For those who discuss to any welder and ask, “Are you licensed?” you are most probably to listen to an enormous, comfortable “YES!” in reply. The true query needs to be, “What positions are you licensed in?” There may be by no means a easy reply to welding certifications, however the fundamentals of welding positions are simple!
Welding certifications are damaged down into two principal classes and a pair extra positions. The primary class is structural welding, principally used for welding square-shaped objects. Structural welding certifications are the most typical and nearly any pupil welders will go them. The second kind of welding certification is for welding pipe. Not many welders have any such certification, as only a few of them are capable of go the examination.
Welding positions are simply that, positions! Structural welding is completed within the flat, horizontal, vertical, and overhead positions. Sq. shapes give a straight line to weld, due to this fact – one angle, and one place at a time. Pipe welding, then again, by no means permits the welder to make use of a single angle or place! When welding pipe, the angle and place of the weld are by no means the identical, as each are constantly altering as you’re employed via your complete weld.
Welding certification positions have a coding system that welders all the time confer with. Structural welding positions are coded one via 4. One is for flat, two is for horizontal, three is for vertical, and 4 is for overhead welding. Most welding certifications are completed in groove welds and what meaning is the weld joint is beveled. The abbreviation that’s used for groove welds is “G”. Placing collectively the coding system is easy. For sensible causes, most structural welders will take two welding certifications. The primary is the 3G place which is a groove weld within the vertical place. The 3G place qualifies the welder to weld within the flat, horizontal, and vertical positions with a single check. The 4G place is a groove weld within the overhead place which qualifies a welder to weld within the flat, horizontal, and overhead positions with a single check. When combining the 3G and 4G welding certifications, the welder is certified to do structural welding in all positions.
Pipe welding certifications use the identical coding system however add a couple of extra positions and mixtures. For pipe welding, the numbering system goes from one via six. One is for a pipe that’s rolled within the flat place, two is for a pipe that’s working up and down alongside the floor of a wall, 4 is a pipe that’s horizontal working alongside the ground, and 6 is a pipe standing on a 45 diploma angle. The 1G pipe place covers flat welding, the 2G covers horizontal welding, the 5G place is a mixture of overhead, vertical, and flat welding, and eventually the 6G place covers the flat, horizontal, vertical, and overhead positions in a single weld joint. There isn’t any such factor as a 3G or 4G Pipe Welding certification. For sensible causes most pipe welders are licensed within the 6G place and that covers all the structural and pipe welding positions in a single check. It is the toughest welding place and the pay scale for a welder with a 6G welding certification could be greater than double that of a structural welder’s wage.
