Pressure Equipment   -   Welder Qualification

Welder certification is based on specially designed tests to determine a welder's skill and ability to deposit sound weld metal. The tests consist of many variables, including the specific welding process, type of metal, thickness, joint design, position, and others. Most often, the test is conducted in accordance with a particular code. The tests can be administered under the auspices of a national or international organization, ISO standards on welder qualification (ISO 9606), with the exception of qualification for steel welders, new version of the old European EN 287-1 standard still applies. Welders involved in the manufacture of equipment that falls within the scope of the Pressure Equipment Directive must be approved by a competent third party which may be either a notified body or a third-party organization recognized by a Member State.  EN 287, ISO15614, ISO 15609-1, ISO 15609-2 etc…
