The Experimental Research on Plasma Welding of SUS 304 Stainless Steel Thin Plates

The article introduces some experimental research results on the application of plasma welding technology for SUS 304 stainless steel thin plates, using welding equipment of LINCOLN CB-MATIC SF 32–33 (USA) with a production industry scale in local conditions of Vietnam. The quality of the weld is preliminarily assessed through the criteria of its surface morphology and the maximum deformation of the weld structure in the state after natural environmental cooling. The experimental results help to set the limitation of the domain of in-depth investigation on the influence of key technological parameters on the mechanical properties and microscopic structure of the weld material, using an experimental design method as a scientific platform to determine the welding mode in accordance with the technical requirements of the mechanical product, which needs to be manufactured.
