Globular welding process

WebJan 11, 2024 · Globular arc welding is regarded as an intermediate step between short-arc and spray-arc welding. In this method, the parameters are 180–260 A and 23–28 V. In globular arc welding, both short circuit transfer and spray transfer without short circuits are used to transfer the filler material. WebMar 20, 2024 · There are four types of metal transfer modes in MIG/MAG or GMAW Welding to transfer the metal from filler wire to weld. These fours metal transfer modes are- Short circuit transfer (Dip transfer), Spray transfer, Globular transfer, and Pulsed transfer mode. The transfer mode is affected by the type of shielding gas, welding current & …
