WHAT IS THE DIFFERENCE BETWEEN AC AND DC WELDING?
Wel come to yo yo Abhinandan WHAT IS THE DIFFERENCE BETWEEN AC AND DC WELDING? A.C . WELDING ☆ONLY WELDING TRANSFORMERS IS REQUIRED CHEAPER . ☆ EFFICIENCY OF TRANSFORMER IS 80 TO 85%. ☆ ZERO CURRENT TWICE IN EACH TEMPERATURE. ☆ EQUIPMENT COST IS LOW. ☆ LESS SPACE REQUIRED ☆ USE OF INTERMITTENT CURRENT REDUCED ENERGY CONSUMPTION. ☆COATED ELECTRODE IS USED. ☆ SPEEDLY WELDING WORK. AC and DC welding are forms of arc welding that use different currents to produce an electric arc. ... The electric arc provides heat to fuse the metals together. A power supply is used to generate the arc, which can either use an alternating current ( AC ) or a direct current (DC). Advantages The advantages of AC welding are: The alternating current between positive polarity and negative polarity allows for a steadier arc for welding magnetic par...
