Plasma-Liquid Welding of Copper Products

Experimental studies and analysis of the obtained results of plasma-liquid welding of products made of M1 grade copper plates with a direct current electric discharge at atmospheric pressure have been carried out. Welding of samples was carried out by immersing a metallic cathode (welded products) in a liquid (non-metallic) anode. Electro physical welding parameters including volt-ampere characteristic were determined. A graph of current and voltage dependencies on time was plotted and the structure of the weld was analyzed by SEM image.
