TP278 full pen weld joint substitution

TP278 full pen weld joint substitution

TP278 full pen weld joint substitution

We are building a M2 Cat.A weldment. TP278 permits Partial Penetration joints within the same design group to be interchanged without drawing changes provided weld efficiencies are not reduced. Is there any allowances for Full Penetration joints? Could I substitute a C2V6 for a C2V5 without a drawing change? Our Weld accessibility will be increased with a C2V6. The drawing requires Records IAW 4.1.3 even though it is a M2 and our customer is not entertaining drawing changes. Thanks for your help.

RE: TP278 full pen weld joint substitution

I believe your last sentence says it all. I assume the original design drawings were submitted and approved by your customer. Any changes/revisions would require approval by your customer.


Best regards - Al
