It only takes one wrong move to put the quality of the weld in jeopardy. Some examples are using the wrong filler metal for the materials being joined; not performing pre- or postheat processes; using the wrong shielding gas; running the wire at the wrong speed; using the amps or voltage outside the proper range; not applying the proper joint preparation; and even something as simple as having a fan blowing toward the weld station that can blow away the shielding gas. These factors all can result in a bad weld.

Properly certifying welders is a requirement for controlling weld quality. A welder qualification is similar to the weld procedure qualification (WPQ) in which test coupons are welded together. The coupon undergoes a bend/break test, and upon satisfactory results, the welder is granted a certification once he or she has passed. Certified welders are issued a stamp number, which is used during production to identify who performed the welding. This initiates accountability and traceability, which increase quality assurance of the welder.
