What are welding equipments?
The welding equipment includes the welding machine, power supplies, and devices directly used to conduct the welding process, jigs and fixtures for the rapid assembly of the parts to be welded, for holding the parts during welding, and for preventing or reducing warpage of the welded articles, auxiliary equipment used …
What is 6G welding position?
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 is 3G welding position?
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 argon welding?
During the welding, process metals are exposed to temperatures of upwards of 7000 Degrees. At these temperatures, most metals become liquid, which allows the formation of the weld. Argon is used to protect the molten pool of metal against elements in the Atmosphere including Oxygen, Nitrogen, and Hydrogen.
What are the 4 types of welding machines?
There are four main types of welding. MIG – Gas Metal Arc Welding (GMAW), TIG – Gas Tungsten Arc Welding (GTAW), Stick – Shielded Metal Arc Welding (SMAW) and Flux-cored – Flux-cored Arc Welding (FCAW).

What is 1G 2G 3G 4G 5G 6g welding?
The positions of groove welds are divided into 1G, 2G, 3G, 4G, 5G and 6G, respectively indicating flat welding, horizontal welding, vertical welding, overhead welding, horizontal fixed welding of pipeline and 45 °inclined fixed welding of pipeline.
What is the 4G welding position?
4: Overhead With this key in mind, what 4G mainly covers is Overhead Groove Welding. Meaning, the ability of welding metals to be joined together in an overhead position. Since this is the fourth, that most likely means that it is the hardest to do from the rest of the welding positions.
What is g5 welding?
In the 5G welding position, the pipe is in the horizontal position. Unlike the 1G position, the pipe is in a fixed position and it cannot be rotated. The welder moves around the pipe in the vertical direction to perform the welding.
What is co2 welding?
Metal arc welding in which the consumable electrode is fed into the arc at a constant speed with a high current density, any alteration in arc length being corrected by naturally occurring changes in the burn-off rate.
What is MAG welder?
Metal Inert Gas (MIG) / Metal Active Gas (MAG) welding refers to a group of arc welding processes that use the heat generated by a DC electric arc to fuse the metal in the joint area. A continuous electrode (the wire) is fed by powered feed rolls (wire feeder) into the weld pool.
What does MIG stand for welding?
metal inert gas
MIG—i.e., metal inert gas—welding is generally used for large and thick materials. It employs a consumable wire that acts as both the electrode and the filler material.
