2021年11月15日 · The welder qualification test coupon or WQT as stated above needs to meet the weld soundness and that is verified either by performing a volumetric NDT test (such as radiographic testing or Ultrasonic testing) or by destructive testing such as bend test. Visual testing is mandatory but it is only for surface inspection.

2022年10月15日 · Welder qualification tests or WQT are used to assess a welder’s ability to deposit sound welds. The most common welding test is the AWS D1.1 weld test as defined in AWS D1.1, Section 6: Qualification, which evaluates a welder’s ability to make sound, full-penetration welds in all positions.

The welder qualification test (WQT) is performed to determine the skill of a welder, in other words, we can say that the welder performance qualification is carried out to check whether the welder or the welding operator can produce a sound weld or not.

Welder Qualification Test or WQT is a process of assuring the quality of a welder’s work. It is a working qualification test and every employer demands qualified welders. For example, in the Pressure Equipment Directive, DIN EN 1090, and the Machine Directive, etc. In the welding field, accuracy of work matters more than anything else.

WELDER PERFORMANCE QUALIFICATIONS TEST (WPQT) While WPS and PQR are used to define and prove the welding process. WQT/WPQT is used to test the actual welder. Is the welder able to produce a sound weld, with the following. • With a particular welding process ie. GMAW or GTAW. • In a given position Horizontal, Vertical or Overhead.
