Aluminum welding agent(Also known as exothermic welding) is a method of heating metals using the superheated molten metal produced by the exothermic reaction between metal oxides and aluminum to achieve bonding.

1. Operation method of aluminum welding agent

Compared with other welding methods,Aluminum welding agentit is simple, convenient, and practical. Thermite welding involves welding two wires together; it is easy to use; similar to a chemical reaction. Thermite welding is a welding process, so it requires its own operation method; the welding process is not complicated or troublesome due to electric welding; this welding process requires a thermite welding mold and a package of thermite welding agent, which can be used over 100 times. One package of thermite welding agent corresponds to one weld point; the weld points of aluminum welding technology have advantages such as being strong, corrosion-resistant, and having good conductivity.

2. Characteristics and advantages of aluminum welding agent

The current cutoff value of the weld point is equal to that of the conductor; the weld point is permanent and will not produce high resistance due to loosening or corrosion; the weld point is like copper but tougher than copper itself, unaffected by corrosion products. The weld point can withstand repeated large surge (fault) currents without degrading; the welding method is simple and easy to implement; the equipment is lightweight and portable; no external power source or heat source is needed during welding; the quality of the weld can be inspected visually; it can be used for welding copper, copper alloys, copper-clad steel, various alloy steels, including stainless steel and high-resistance heating source materials.

3. Introduction to aluminum welding agent process

Thermite welding is a process for welding two or more wires or connections between pipes in cathodic protection. The aluminum welding agent process typically consists of thermite welding agent and thermite welding molds.

Thermite welding was established in the late 19th century when scientists discovered that the exothermic reaction between aluminum powder and metal oxides could be initiated by an external heat source, and once the reaction could sustain itself, its general formula was:

Aluminum oxide (powder) aluminum metal thermal energy

Exothermic welding can primarily weld pure copper, brass, bronze, red copper, copper-clad steel, pure iron, stainless steel, wrought iron, galvanized steel, cast iron, etc.
