A 6G welding test is a certification exam that requires test takers to weld pipes and plates in all positions, including overhead, vertical and horizontal positions. Welding using both left and right hands may be necessary.
Pipe welding has five distinct positions and two types of joints. Different positions are assigned with specific numbers or letters?such as 1, 2, 5, 6 and R?that describe the positions of the pipe. The 6G pipe welding certification is considered one of the toughest tests due to the immovable placement of the pipe and its position at a 45-degree angle.
The American Welding Society administers the pipe welding exam with the help of other organizations. More than 80 accredited testing facilities are accessible to applicants, as of 2015. Private firms and welding schools also offer the certification test.
Applicants who choose to get certification from the American Welding Society must submit a registration form that requires their test scores, personal information and details about the kind of certification they want to obtain. They apply through a third-party testing site and send the test results together with the registration form. Those who apply to other certification providers undergo a training course and take a hands-on exam. A minimum of two years of welding experience or a 3G welding certification is typically required to apply for a 6G certification.
