Optimisation of GMAW via the alternating shielding gas technique
The use of the alternating shielding gas technique in arc welding systems has been previously studied due to advantages such as greater penetration of the weld joint, refined microstructure of the fusion zone, reduced heat input, and increased travel speeds of the welding torch. Yet, relatively …
