1. Characteristics and advantages of exothermic welding

(1) The current closure of the welding point is equal to that of the wire;

(2) The welding point is permanent and will not cause high resistance due to loosening or corrosion;

(3) The solder joints are like copper, but are tougher than copper itself, and are not affected by corrosive products;

(4) The welding point can withstand repeated large surge current (fault) without degradation;

(5) The welding operation method is simple and easy to use;

(6) The equipment is light and easy to carry;

(7) There is no need for external power or heat source during welding;

(8) The quality of welding can be verified from the appearance;

Can be used for welding copper, copper alloy, copper plated steel, all kinds of alloy steel including stainless steel and high resistance heating heat source material.
