Different types of welding electrodes Normal welding electrodes- Welding joint between Steel to Mild Steel Hard Facing electrode Welding electrode for Mild Steel and High chromium alloy joint For Simply for welding purpose we generally use 7018 and 6013. These above two electrodes use for general purpose , This 7018 and 6013 electrodes is very must useful in rusty - dusty areas. Applicable for - Vehicles bodies joint Ship Structure welding works Mechanical Structure works Beams and structure works Welding Electrode 7018. 7018 = 70 and 1 and 8 Frist two digit show Tensile strength of electrode material 70= 70000 Pounds per square Inch Tensile Strength Third Digit show the welding position Mainly three position of welding if 1= Stands for all positions 2= For flat and horizontal positions 4= Stands for overhead, vertical, horizontal, and flat electrode positions. Fourth Digit show the taking current during welding The last digit implies the coating t...
