Welding Inspection & Metallurgy API ICP Self Study Notes

Due to this inherent nature of the welding process the BPV Code Section IX,
restricts this process by:
a. Requiring welders qualify with mechanical testing rather than by
radiographic examination.
b. Limiting the base metal thickness qualified by the procedure to 1.1 times
the test coupon thickness for coupons less than 1/2 in. thick (12.7 mm) per
variable QW-403.10.
c. Limiting the deposited weld metal thickness qualified by the procedure to
1.1 times the deposited thickness for coupons less than 1/2 in. thick (12.7
mm) per variable QW-404-32.
d. Making variable QW-409.2 an essential variable when qualifying a welder
for the GMAW-S process.
