The 1G is horizontal rolled position weld. The 2G is Vertical Position. The 5G is horizontal fixed position. And the 6G is inclined fixed position that is at about 45 degrees. It is necessary that you understand the welding position norms.
What does 6G welding mean?
The different welding positions for pipe welding are 1G, 2G, 5G and 6G positions. The 1G is horizontal rolled position weld. The 2G is Vertical Position. The 5G is horizontal fixed position. And the 6G is inclined fixed position that is at about 45 degrees.
What is a 2G weld test?
A 2G weld test checks your proficiency at producing welds that meet specific criteria for the finished weld and includes: Welding two horizontal beveled plates. Proper setup. Making the weld with or without a backer plate.
What is 3G welding?
Welding in a 3G position means moving the torch vertically, up and down across a surface. This is in contrast with 1G (flat surface welding), 2G (horizontal welding), and 4G (overhead ceiling welding).

What is 6G in welding?
In welding, a 6G position requires one pipe to be positioned at a 45-degree angle to the other. Both are horizontal. This presents a very challenging position for a welder, who uses all his skills and a variety of body positions to accomplish the most difficult weld in the 6G join: the overhead weld.
What does 3 G stand for in welding?
Welding in a 3G position means moving the torch vertically, up and down across a surface. This is in contrast with 1G (flat surface welding), 2G (horizontal welding), and 4G (overhead ceiling welding).

What is 3G and 4G welding?
By taking the 3G and 4G welding certifications together, it certifies you to weld plate in all positions, and to do fillet welds on pipe with a minimum diameter of 24 inches. ... When doing horizontal and overhead welds they are typically done in stringer beads verses flat and vertical welds using weave welds.Jul 21, 2021
What is a 2G welding test?
A 2G weld test checks your proficiency at producing welds that meet specific criteria for the finished weld and includes: Welding two horizontal beveled plates. Proper setup. Making the weld with or without a backer plate.
