1.0 BCOPE l
1.1 This instruction establishes.the Quality requirements associated with the application of temporary attachments to the TRUPACT-container or subcomponents and the t
inspection of base metal upon removal of the attachments.
2.0 RESPONSIBILITIES 2.1 It shall be the responsibility of the Quality Assurance Manager to assure that welder. and welding data is properly recorded, visual, dimensional and nondestructive testing is properly performed and documented.
2.2 It shall be the responsibility of the Inspector to assure that welding of temporary attachments.is performed using.
a qualified welder and an approved welding procedure.
3.0 PROCEDURE 3.1 Temporary attachments, which are-installed for the purpose of handling or controlling material dimensions during fabrication, shall be located in an area which has sufficient thickness to prohibit a minimum wall violation l
once the. attachment has been removed and the area blended.
I 3.2 Quality Assurance shall establish hold points during the l
preparation of inspection planning to assure that all required inspections are performed.
l 3.3 Attachments shall be.made using a welder and welding procedure qualified in accordance with Section IX of the ASME Code.
The material and welding consumables used shall be identified and compatible with the materials.
being joined.
This information shall be recorded on a Manufacturing / Inspection Plan (MIP) or Weld Repair Data Sheet as depicted in QI-5.1.
QA will verify the subject information.
3.4 The Welding Supervisor shall notify QA of any intended attachments which will infringe on the inspection area of the weld joint (1/2" on each side) in order that the base metal can first be inspected for surface discontinuities.
This inspection will consist of a visual and liquid penetrant examination which will be documented on the l
applicable traveler.

1 testing' as was originally: required.
Results'of-the re-examination shall be documented on the affected traveler.
3.5.After, removal'of temporary. attachments.and blending'of
.the base metal, Quality Assurance-will perform the following inspection:
A.
Visual inspection of base metal-B.
Liquid penetrant' inspection of base. metal
.C..
Ultrasonic digital thickness dimensional inspection l
of base metal-Results, including a-sketch showing theHlocation ofithe.-
attachment, will. be. documented on the-appropriate
. inspection forms and attached to the, MIP; and/or Weld Repair Data Sheet-which will be. incorporated.into the-final data package.
3.6 A Quality Discrepancy. Report will be generated,.in accordance with QI-7, to disposition.' unsatisfact'ory inspection results.
