,erry o,a arc acvertisigg April 20, 1979 Mr. Robert Minogue Director of the Office of Standaras Development

!Juclear Regulatory Coccissica Washington, D.C. 20555

Dear Mr. Minogue:

In light of recent deveicpcents at the Three Mile Island nuclear pcwer plant, I thought it might be worthwnile to bring to ycur attention a pecduct manufactured by a client of c_ne, the G.A.L. Gage Cocpany, Inc. The HI-LC#

Welding Gage, manufactured by G.A.L.,

is a device used to properly align butt and socket welds en critics.1 piping systems used in the construction of nuclear generating plants, i.e. reactor coolant.

As you may see by the enclcsed literature, the HI-LC8 gage ceasures internal mismatch on butt welds to 32nds of an inch, well within the existing codes.

It also allows proper setup of socket welds. An improperly spaced (1/16" minimus) socket weld is difficult to detect during construction, but can becoce plainly apparent during in-service operation of a nuclear plant.

The HI-LOe gage improves welding accuracy (and therefore performance safety) and cuts welding time and waste (and therefore costs).

The G.A.L. HI-LC' gage is now used by many of the =ajor nuclear power plant canufacturing cocpanies, wit". the notable exception of Eabccck and Wilcox, the cca,any which designed and sup;11ed critical cccpcnents fcr the Three Mile Island plant.

The G.A.L. Gage Cc=pany would be happy to forwarc a gage to you fcr inspection and/cr testing prcposes.

For any forcher information please contact Mr. Goodwin A. Lycan, G.A.L. Gage Ccapany, P.O. Ecx 231, Stevensville, Michigan 49127.

I tl Ycu can reduce welding costs in all tnese ways anc core with cne, hanay pccKet tool.....the G.A.L. HI-LC# Welding Gage.

The G.A.L. HI-LO" Gage measures key welding dimensions to an accuracy (1/32") not pessible any other way.

This extreme accuracy permits quicker more accurate fit-ups that checx cut within code limitations, thereoy C'JTTI?;G WELDI:;G COSTS!

A fitter can get the exact alignment quicker and easier.

delders know their welds are accurately prepared and completed.

Q.C. People can confirm their inspecticns are within coce.

All wit e ne HI-LC# Uage.

And these accuracy savings come on a number of measurenents!

The HI-LC# Cage gives craftsmen or inspectcrs an easy way to ceasure these welding dimensions to 1/16" (1/32" where in".icated):

OF THE ~Hi-LO" l

TOCL FOR FIT-LPS wfLOERS GAGE Mh AND RACIOGRAPHED W ELDS.

The spring-loaded Vlier plunger allcws smooth slide action, making measurement adjustments quick anc easy -- a lockscrew holds measurements for later comparison or transfer. The exclusive G.A.L. wide bocy assures interior alignment stops are parallel with the pipe run.

Over 90 ccrooraticns and oublic utilities includine the NRC are cresently usine the HI-LC# Gate to cut their welding costs.

Is it any wonder?

Rejects at any stage in a weld are costly -- some running to twice, three times, even ten times the proper cost of the weld.

These rejects start cefore any welding cegins -- witn improper alignment. Assuring internal mismatch ceet codes before expensive welding starts is wnere the HI-LOS Gage can save substantially.

Recember GOOD FIT-UP assures a GOCD WELD.

Just one simple gage....to get seven different ceasurements....to give ccre accurate fit-up and assure acceptable ccmpleted butt welds...to cut rejects at every step in the welding process....to assure that socket welds are ccmpleted within the code (1/16" pipe-end-to-shoulder gap to allow for thermal contraction).

But don't take our word for it.

One HI-LC# Gage on ycur job site will deconstrate its worth. Give it to a fitter cr welder to monitor fi'-up.

Let welders Use iL to check fillet weld legs (codes require tso passes eini.,un) before they tcve to the next weld. Tell your Q.C. pecole co use it anc watch the accuracy of their internal mismatch inspecticns increase.

We're sure you'll find what over 90 corporations have already found:

that the HI-LC' Welding Gage will save you two to three tines its $43.00 price during the first month alone.

(Elicinate one radiographic reject because of improper fit-up or internal miscatch and you've more than paid for the gage.)

To test this sage for yourself, just fill in the reservation form and forward it with your ccmpany's purchase ceder.

We'll ship ycur HI-LC* 3 age via U?S the same day we receive ycur nctice. Cr call 616/429-1793 for shi; cent tocay.

Then you can start recucing welcing rejects anc cutting welcing costs i =ediately!

Hope to hear feca you scon, 0s.

=M, C.A. Lycan, President G.A.L. Sage Iccpany GAL::s P.S. -- Everycne wnc usec the HI-L35 Welding Gage quickly sees its value

-- so gages have a tencency tc te "tcrrowec".

'ince everycne wants cne, it caves t1:e and trcu;1e (and acney) to arc;r in quantity.

More people using the HI-L3* gage en your ;cb means greacer aa'ings in time and materials.

Groer tocay and start caving rignt away.
