Assessment Process
Assessment Process
The Maintenance Welder Competency is not assessed using a simple pass/fail criteria as is normally used for determining compliance to a standard. There are mandatory elements that the Welder must demonstrate, such as safe work practices and process proficiency.
However, whether a Welder passes is mostly determined by a total score that is based on the overall marking and weighting assigned to the various elements. In this way, a pragmatic approach can be adopted for determining the overall competency of a Welder, rather than strict pass/fail criteria.
A formal Certificate and a sticker with the competency level will be supplied on successful completion

During the course of the Welder completing the coupon, the Accredited Supervisor will be making observations and carrying out inspections.
The data recorded by the Supervisor is supplied to WQMS for use as part of the overall assessment and grading.
Visual Inspection Click to expand
The finished coupon should pass the acceptance criteria as defined in the Maintenance Welder Competency
NDT Click to expand
The coupon must pass MPI with no cracking evident
UT of all welds will be carried out to identify the presence of any imperfections/indications. The locations of any indications will be marked on the coupon, and an NDT report provided. The NDT report shall state whether the coupon complies to AS1554.1 UT requirements.
Mechanical Testing Click to expand
A total of 4 macros will be cut, polished and etched.
One of the macros requires 5 Vickers Hardness traverses to be done through the HAZ of the welds
Sport hardness checks are required on the other 3 macros to find the peak hardness
