AWS D1.1 Welder test. Bends or radiographic examination ?

AWS D1.1 Welder test. Bends or radiographic examination ?

AWS D1.1 Welder test. Bends or radiographic examination ?

I intend to test welders to a WPQR that was approved using a metal core wire (AWS A5.18 E70CGMH4) for the root & a Fluxcore Wire (AWS A5.29 E81T1-Ni1M) for the fill & cap

I note that AWS D1.1 allows a substitution of RT for guided bend tests, except for joints welded by GMAW-S
Is this acceptable with the root wire used? I'm assuming that this wire comes in the short circuiting transfer grouping

RE: AWS D1.1 Welder test. Bends or radiographic examination ?

Transfer mode and wire classification are two different things.  What mode was used when it was welded?

RE: AWS D1.1 Welder test. Bends or radiographic examination ?

metal cored wire can be used in short-circuit, globular, or spray, it just depends on the paramers used during welding.

RE: AWS D1.1 Welder test. Bends or radiographic examination ?

Thanks for the response GRoberts & HgTX

The welding parameters used in the WPQR for the root:-
Amps 90 Volts 24, is this in the short-circuit dip transfer range?
The fillers were welded using a range from 163-174 amps and 21-23 volts
To me it seems as if I have a weld made part with short-circuit transfer and part with spray.
How do AWS define the two types of weld transfer?

RE: AWS D1.1 Welder test. Bends or radiographic examination ?

You can look in the "Recommended Practice for GMAW" published by AWS or you can look in the AWS Handbooks. In either, there is a diagram that shows the amperage and wire feed speeds for short circuiting transfer and spray transfer for carbon steel using different electrode diameters.

In any event, the voltages and amperage's you list, it is likely the short circuiting transfer mode was most used if you can depend on the data provided. You didn't list the electrode diameter or the shielding gas used, so my guess is as good as any with the information provided.

I would use bend tests.

Best regards - Al
