GMAW-s WPQ qualified 1

[moe27]

ASME IX
WPS GMAW-s P1 material qualified up to .275" thick weld deposit thickness.
A welders qualifies on .25" thick metal a groove weld....what range of deposited weld metal would the welder qualified for?

 

[SectionIX]

Welder is qualified up to 0.275" (0.25" * 1.1)


ASME IX, QW-404.32 For the low voltage short‐circuiting type
of gas metal‐arc process when the deposited weld metal
thickness is less than 1/2 in. (13 mm), an increase in deposited
weld metal thickness beyond 1.1 times that of the
qualification test deposited weld metal thickness.

See Table QW-355 for other restrictions.

Thank you for that reply....checks out with what I have been told.

And all GMAW-ss coupons require bend testing. RT will miss the interbead Lack-of-Fusion that short-circuiting will give when run 'cold'.
