6G Welding Test Techniques

A 6G welding test is used to measure the skills of a welder studying toward a 6G welding certification. This certification allows companies to guarantee their workers can weld correctly in different positions and circumstances and still meet the welding quality standards required of them. The 6G pipe test, for instance, requires you to weld a pipe fixed on a 45 degree angle. If you are planning to take a 6G welding test, check standards that will be used to assess your work. There are several organisations that provide standards and best practice guidelines on welding such as the American Society of Mechanical Engineers and the American Welding Society.

Welder Position

There are four main position techniques used in a 6G welding test: vertical, horizontal, flat and overhead. This describes the position in which you must weld. The test assesses your ability to adapt to different working positions.

Pipe Position

The 6G test also looks at your technique when welding pieces which are fixed in different positions. There are four position techniques you must practice in your 6G test: horizontal rolled, horizontal fixed, vertical and inclined positions.

Testing and Repair Technique

The 6G test also looks at your technique when testing your finished products and carrying out necessary repairs. You should know what test is required for each test sample. For instance, a 6G pipe weld requires you to visually inspect for any cracks and excessive weld reinforcement . You must then test the pipe mechanically by bending the pipe and checking the weld holds under the pressure.
