Under ISO 9606-1, welder competency testing is focused on the three key elements required of a welder, including the ability to: Set up a welding machine. Read a welding procedure. Welding a coupon in ing with the relevant acceptance criteria.

This is caused by the welding wire moving through the contact tip.

For arc welding the main parameters are as follows: Welding current....The other parameters which may be measured and recorded are as follows: Wire feed speed (for MIG/MAG) and other processes with a filler wire. Gas flow rate (shielding, backing and plasma) Temperature (pre-heat, inter-pass and post-weld heat treatment)

It determines the performance qualification thickness range i.e. up to what thickness the welder can weld. AWS D1. 1 and ASME BPVC Section IX are two widely used welding codes. In ASME BPVC Section IX the performance qualification thickness limit for groove weld is given in Table QW452.

The most commonly used codes for qualifying welders are the American Society of Mechanical Engineers (ASME) Section IX and American Welding Society (AWS) D1.

ASME section IX is a part of the ASME boiler pressure vessel code that contains the rules for qualifying welding procedures and welders. It is also used to qualify welders and procedures for welding to ASME B31.

As you probably already know, a welder's qualification continuity log must have an entry made periodically that specifies the process the welder has made a weld to and the date the weld was made. With so many welders working for your company, maintaining each welder's continuity log can quickly become overwhelming.

BS 4872 applies to a wide range of general fabrication work where an approved welding procedure test is not required. Welds would usually be carried out in ance with written instructions and the test weld, subject to visual or surface inspection, a bend and fracture test.
