Plasma arc welding involves joining metals together by heating with a constricted arc between the workpiece (transfer arc) and an electrode (non-transfer arc) OR the constricting nozzle and the electrode.The constricted plasma that is formed is highly ionised and concentrated. In simple terms, plasma arc welding uses plasma (gas) that has been superheated to become… Continue reading What Are The Advantages and Disadvantages of Plasma Welding?
