Gmaw modes of metal transfer
WebJun 4, 2024 · Gas metal arc welding (GMAW) is a welding process in which an electric arc is formed between a wire electrode and a metal workpiece alongside a shielding gas to protect the arc from contaminants. There are several ways in which the molten electrode droplet can be transferred to the weld pool known as metal transfer modes. Identifying … WebThis metal transfer mode is commonly used for carbon steels with 100% CO 2 shielding gas. In addition, the transfer is only used in flat and horizontal position, as the formed …
