AWS D1.1 Question

admin

Hi!I'm new in the forum. And I have already introduced my self in the "introduce your self" section.I have some question and I really hope you can help me.Here is my doubt: In AWS D1.1 section 4.11.3 it is not clear for me when it is applicable and when do I have to qualify the proposed combination that 4.11.3 describes.AWS D1.1 states the following:"4.11.3 Consumables Verification Test. If both the proposed welding consumable and the proposed WPS for welding teh fillet weld test plate or test pipe described in 4.11.2 are neither prequalified nor otherwise qualified by Section 4, this is: (1) If the welding consumables used do not conform to the prequalified provisions of Section 3, and also(2) If the WPS using the proposed consumable has not been established by the contractor in conformance with either 4.9 o 4.10, then a CJP groove weld test plate shall be welded to qualify the proposed combination."May be, I don't understand this part because of my English. But still, could anyone help me with this?THANKS A LOT!
Reply:If you're not using an AWS certified filler metal, and an AWS approved welding procedure, then you must weld a test plate and subject the test plate to various mechanical tests.Most commercially available filler metals are AWS certified.  Check the manufacturer's website and product data sheet for the filler metal you're using. If you're using some filler metal that isn't AWS certified, you need to prove that it can produce a sound weld.If you're not following a standard welding procedure, then you need to demonstrate that the procedure you want to use will produce a sound weld when followed by a weldor.Benson's Mobile Welding - Dayton, OH metro area - AWS Certified Welding Inspector
