Welder qualification tests

Why is a welder qualification test necessary?

The necessity of welder qualification tests relates to assuring the quality of welding work which is carried out by your employees. The deployment of certified welders is stipulated in many sets of rules, e.g. in DIN EN 1090, the Machine Directive, the Pressure Equipment Directive etc., or sufficiently qualified personnel is demanded within the framework of the product liability and by the client.

Welder qualification tests for manual welds with the autogenous, manual metal arc, MIG/MAG and TIG welding processes are required, for example, for components made of steel or aluminium for tank structures, steam boilers, civil engineering, bridge and hydraulic structures, pressure equipment, ships, pipelines, rail and road vehicles, wind energy installations (onshore and offshore) etc.
