t 1.0 PURPOSE
~
The purpose of this report is to provide final data and a
information as required by 10CFR50.55(e)(3) subsequent to the notification of a reportable deficiency.
The subject deficiency is associated with spot / resistance welding in strut material.
2.0 SPOT-WELDED STRUTS 2.1 Struts O
Basic strut sections are light gage (thickness varying from 0.105 to 0.109 inch) channels manufactured by cold forming mild steel strip.
These channel sec-tions are connected to each other in various configura-tions such as back-to-back, back-to-side, or side-to-side by using a welding process commercially known as spot-welding or resistance welding.
The channel sections and built-up sections used on Susquehanna project are either mill-galvanized or hot-dip galvanized af ter spot-welding and are supplied by Unistrut Corporation, Wayne, Michigan; Power Strut, Division of Van Huffel Tube Corporation, Warren, Ohio; and B-Line Systems Incorporated, Highland, Illinois.
These were procured as standard off-the-shelf items with no formal Quality Assurance.
Various configurations used on Susquehanna are given in Figure I.
Strut members are used in field fabricated supports for electrical raceways, HVAC ducts and instrumentation s (P-133a)
s t
lines.
The governing documents are drawing 8856-E-53 for electrical raceways, Specification 8856-M-323-C for HVAC ducts and Drawing 8856-JG-16 for instrumenta-tion.
The supports are designed in accordance with ' Specifi-cation for the Design of Cold-formed Steel Structural Members' (1968 Edition), published by American Iron and Steel Institute.
0 2.2 Spot-Welding
/~
The spot / resistance welding process consists of passing high current through the thicknesses of adjoining plates resulting in metal-to-metal fusion.
The quality of a spot weld is dependent on many variables such as pres-sure on the electrode tips, finish of the material, presence of impurities on the material, build-up of zinc and other contaminents on the welding electrodes, contact between joining surf aces, voltage and amperage.
Therefore, unless these parameters are closely moni-tored and controlled, the result may be inadequate fusion.
3.0 BACKGROUND
Since the use of strut material began on the Susquehanna Pro-ject, there were three isolated instances when the adjoining channels separated during handling or assembling.
These member lengths were rejected.
- (P-133a)
t However, in recent months there have been significant in-stances on other nuclear projects where inadequate fusion was observed at the weld spots. _ As_a_ result of this, on March 25 and 26, 1978, Bechtel field engineering personnel performed an inspection on Unistrut member P-1004A, Power-strut member PS-3022 and B-Line member B22-X.
The tested members were part of installed electrical raceway and' HVAC duct supports.
The method of inspection consisted of
' sound ing' the members with a ball peen hammer to detect
/'
separated spot welds and verification of the separation by insertion of a card between the members at the spot welds.
The inspection indicated a high incidence of spot-welds with inadequate or no fusion. Therefore, Project Quality Assurance (QA) issued Management Corrective Action Report (MCAR) 1-23 on March 28, 1978.
4.0 DEFICIENCY AND ITS SAFETY IMPLICATIONS Based upon the results of the inspection as described in Section 3.0, it was determined that:
a.
The deficiency is related to spot-welding technique and/or procedure.
b.
The quality of the spot-welding is indeterminate, without further investigation.
Various combinations and configurations of channel struts have been used in the support systems.
Individual members l (P-133a)
I
r o
ste 28 78 093470 1
have been designed as composite sections for which the con-nection (spot-welding used in this instance) between adjoin-ing channels is relied upon to carry the postulated loads within established design margins.
Thus, inadequa te fusion at the spot-welding may result iri inadequate strength, and may adversely affect the safe operation of the plant under
~
design loading conditions.
5.0 IMMEDIATE ACTION 1
A ' Hold' was imposed on f ur ther installation o f member P-1004A or its equivalent unless the member was stitch-welded to develop equivalent design strength of the spot-welding.
6.0 TEST PROGRAM 6.1 General Although it was determined that a deficiency existed in scme spot-welded members, the ex ten t o f the de-t
-'l ficiency was unknown.
So the first step was to es-tablish the scope of the problem.
Since there is no practical nondestructive method for examining the sound-ness of spot welds in the erected material, it was de-cided to initiate a destructive test program.
6.2 Basis of Test Program The underlying approach is described below.
W (P-133a)
a.
Obtain representative samples, selected at random, from the installed and stock material for all shapes and manufacturers.
o.
~~~~
b.
Perform destructive shear test on the samples to obtain failure loads, Analyze the test results,-statistically for each shape c.
and manufacturer to compute corresponding expected strength per spot-weld at a certain confidence level.
6.3 Samples Samples were obtained by Bechtel field engineering personnel and sent to a recognized testing laboratory.
Samples were typically 6" long containing two spot-welds.
For the stock material, two samples were obtained from each 20'-0" length and only one sample f rom any given installed member selected at random.
For the installed A--
material, generally one sample was obtained for every 100 feet of the installed quantity.
6.4 Testing Testing was done by Pittsburgh Testing Laboratory (PTL) 1 in Pittsburgh, Pennsylvania.
Test method and procedures are f ully described in PTL's report. (See Attachment A).

-s-(P-133a)

i i
- 6. 5 ' Statistical Analvsis Based upon the test results, histograms were plotted for each shape and manuf acturer.
Mean and standard deviation were computed for each case.
The test results generally follow the no'emal distribution.
The expected failure load per spot weld was determined by using the mean of the failure load based upon the test results and subtracting one and a half times the standard deviation.
This approach provides more than 90% confidence level for the expected failure load.
Based upon above criteria, the expected failure loads were computed and are given in Table I.
7.0 TECHNICAL EVALUATION
OF DEFICIENCY 7.1 General The technical evaluation in this section is limited s.
to all strut members installed and/or at the jobsite which are not fabricated.
7.2 Design Criteria and Theoritical Considerations AISI specification specifies allowable shear strength j
per spot-weld to be equal to 1.65 kips with a f actor 4
of safety of 2.5 for 0.109 inch thickness.
This al-lowable shear is based upon " Recommended Practices
~
_6_
(P-133a)
s for Resistance Welding," AWS C1.1, by American Welding Society.
Based on this criteria, failure load for a spot should be over 4,000 pound-However, in light of the problem associated with spot-welding, it is necessary to assess bases of code requirements and evaluate structural adequacy of the installed material without compromising the basic design philosophy.
The connection provided by spot welds between adjoin-ing channel sections is relied upon to maintain the integrity of the built-up sections.
The calculated shear in a spot weld in a member depends upon many variables such as loading, sectional properties, end conditions and if the member is used as a beam, brace, column or tie.
The allowable shear of 1.65 kips / spot specified by the code is the upper limit for designing purpose.
However, frcm the evaluation point of view, it is more realistic to consider actual maximum design shear cal-culated individually as required for each shape.
Sec-ondly, for the strut material (F
= 33 k.s.i.) the y
allowable bending ctress (Fb) per code is 20 k.s.i. for 0.105 inch thickness.
Therefore, the f actor of safety for the bending stress is considered to be 1.65 while for the spot-welds it is 2.5, which is rather high.
Reason for this could be attributed to many variables, h
affecting the weld strength.
For the material in ques-s tion on Susquehanna, an extensive test program has been carried out and expected failure loads for each shape are well defined.
Therefore, it is reasonable to as-sume that a factor of safety of 2.0 for spot-welds, which is still higher than the f actor of safety for bending of the strut materia _1 would still be adequate and consistent with the basic design philosophy.
(i 7.3 Comoutation of Design Shear Design loads on the support systems are governed by many considerations such as type of support, structure, elevation, etc.
For individual members in a support,
[
design shear forues additionally depend upon if the members are flexural or axially loaded.
It is noted that for flexural members, shear forces are generally
(
high.
For simplifying the presentation of design shears for this report design calculations were re-viewed and a 5'-0" long member supporting uniformly distributed load was considered to be a representative case for all various loading conditions and member shapes.
Accordingly, for allowable bending stress as governing, corresponding uniform load and shear forces were computed for each shape used. w (P-133a)
< c r
7.4 Summary Table II provides the computed design shears per spot and expected failure loads including corresponding factor of safety for each configuration.
Sections with a factor of safety equal to 2.0 or more, are considered as acceptable with no repair.
For remaining sections, a detailed analysis / design is being performed.
On completion of this reevaluaYi~on, the members will be strengthened as required to meet k
the criteria discussed above.
8.0 CORRECTIVE ACTION 8.1 General Corrective actions are grouped in many categories.
Each category and corresponding action is described below.
8.2 Installed and Stock Material 8.2.1 Powerstrut PS-3022, Unistrut P-1004A and B-Line B-22X.
Based upon the inspection by Bechtel field engineering personnel, all material of this configuration was deemed to be deficient, and will be completely repaired without taking any credit for the existing spot welds.

'~'
- ~ ~ ~
,.. f.
h dh 8 h9 bb 8.2.2 B-Line B-llA.
Installed and stock quantity for this shape was small, there fore, no samples were obtained.
In the absence of any test data on the existing spot welds, this section will be repaired to develop required design streng th.
o 8.2.3 Power s tr ut PS-201, PS-151, PS-3080 and PS-202, Unistrut P-1001, P-5501, P-1001C, P-3301, P-1001A, and P-1001C3.
(~
Based upon the technical evaluation in Section 7.0, existing spot-welding is adequate and'will l
per form satisf actorily under design loads.
There-fore, no further action is deemed necessary.
Unistrut P-1001 and Powerstrut PS-201:
For the members with shor t span and comparatively heavy point loads, in conduit supports, the existing spot welding requires further evalta-tion.
These specific cases are presently be-ing analyzed and the members, if determined to be inadequate, will be repaired.
8.2.4 Power s tr u t PS-101 and PS-204, Unistr ut F-5001 and B-Line B-12A.
7 ( P-13 3 b)
se 28 '78 ' 0 9 3 4 7 0 These member s do not meet the design criter ia,
therefore, a detailed re-analysis and redesign will be per formed to compute required additional strength and design drawings will be prepared to show the necessary repair details.
The re-quired repair will then be per formed on the in-stalled and stock material.
On completion of the repair, the strut material will satisfy the
~~
design eritet la.
['
8.3 Strut Material to be Received in the Future Until now, the strut material was procured as a stan-dard 'of f the shelf' item.
However, in light of the problem experienced with the spot-welding, a new speci-fication 8856-C-92 (see Attachment C) was developed for l
procurement of all struts in the future.
The results of the testing by PTL positively indicate that the spot-welds on a plain material have much higher streng th than spo t-weld s on mill-galvanized mater ial.
Therefore, the specification stipulates that strut l
material to be coated after spotwelding.
In addition to this, to provide a reasonable assurance o f attaining the design strength, the supplier is re-quired to introduce a destructive testing program on the production samples and no material will be shipped to Susquehanna j obsite unless it meets the acceptance criteria.
This action should prevent the recurrence of this problem in the future.

SEP 28 '78. 0 9 3 4 7 0 9.0 REPAIR METHODS 9.1 General Construction has been provided the option to select any one of the following methods on a case-by-case basis.
9.2 Replacement This method is to replace the deficient material with new mater ial to be procured per Specification 8856-C-92 ( see Attachmen t C).
9.3 Mechanical Fasteners Second method is to provide 1/4" dia. self-drilling and self-tapping metal screws to obtain required shear streng th.
These screws will be procured per l
Specification 8356-C-91 ( see Attachment C).
In order to assure streng th r equirements for the screws, it is required to per form a destructive shear te st on samples and each lot must meet the acceptance criteria.
In addition to self-drilling and self-tapping screws, other mechanical f astener s ar e being considered such as pop-rivets or clamps.
If these are determined to be technically acceptable, they will be used as al te r na te to the screws.

10.0 CONCLUSION
On completion of the required repair / replacement of the existing spot-welded struts determined to be deficient, the existing support systems will be structurally ade-quate to satisfy the design requirements. Secondly, pro-curement of new spot-welded strut material per new spec-
\\
ification (see Attachment C), will provide adequate as-surance of preventing the recurrence o f this problem in the future.

8856 F 28671 REPORT July 19, 1978 2.4 (Continued) for performing the destructive test.
Every care was taken to insure that a sample would contain two complete spot welds.
Wherever this was not possible, the deviation / variation is noted on the e
test records, i
3.0 ULTRASONIC EXAMINATION 3.1 All spot welds in a sample were marked serially on the sample and then examined ultrasonically using the test procedure No. PTL B-1001.
(See Appendix "D")
3.2 The results (i.e. the gradation according to the soundness of welds) were noted on the test records.
(
3.3 For shape Q, no ultrasonic examination was done, because it was not feasible due to its configuration.
4.0 TENSION TEST 4.1 General l
The samples to be tested for tension loading were marked by Bechtel.
Tension test was performed using the test procedure PTL T-S 2000.

July 19, 1978 4.4 TESTING The test comprised of pulling the two channels connected by the spot welds away from each other.
The samples were so positioned that each spot weld would be subj ected to equal load.
The load
.(
was applied until both the welds failed and the channels separated.
5.0 SHEAR TEST 5.1 GENERAL The shear test was performed on 500 samples using the test procedure PTL-T-S-2000. (See Appendix "D")
5.2 EQUIPMENT USED i
J See Section 4.2 5.3 FIXTURES Special fixtures were designed and fabricated by PTL.
They were designed so that one channel (two channels for shape N) could be held in fixed position, thus allowing the other channel to move.

8856 F 28671 REPORT July 19, 1978 5.4 TESTING 5.4.1 For Shapes J, K, L, P, Q, and R One channel was held in position by the fixture and a compression load was applied to the other channel, which resulted in a g
shear load being applied on the spot welds.
5.4.2 For Shape N The test was performed in two operations on this shape to obtain the ultimate shear load for each set of spot welds.
First back to back channels were held in position and the back to side channel was pushed down.
Subsequently, one of the back to back channel was held in position and the load was applied to the other channel until it was separated.
5.4.3 For Shape M Because of the peculiar configuration of this i
shape, a tension test was performed on this section which would result the spot welds being in shear.
A sample for this shape had a total of eight spot welds.
It is noted that, Page 8
