Exothermic Welding Products

Exothermic welding safety:

1. All personnel participating in aluminothermic welding must wear protective goggles during the operation.
2. Protective eyepieces it is recommended to declare that glass eyepieces replace existing plastic eyepieces.
3. The aluminothermic welding site shall be isolated by the warning line, and the equipment of the thermite welder shall be classified and placed in a place that does not affect the construction operation.
4. The area should be divided, the warning line should be drawn, the tools should be placed neatly, and each joint after welding should be cold polished thoroughly.
5. When grinding, the grinding wheel can not fall into place at once, but should be polished step by step, layer by layer.
6. Oxygen, acetylene regulating valves and gas pressure gauges should be regularly inspected and marked.
7. The welds after each welding are numbered and recorded, and the welds are welded after cooling.

Exothermic welding advantages

1. Good electrical conductivity:the current-carrying capacity of the welded joint surface is almost the same as that of the metal conductor, and the electrical conductivity is strong. Experiments have shown that the change rate of DC resistance before and after welding is close to zero, which is incomparable with any traditional connection mode.
2. Long and durable life: due to the high temperature fusion between the metal conductors during exothermic welding, an integrated permanent joint is formed, which is very strong and difficult to break and damage.
3. Strong corrosion resistance: the material of the welded point is mainly copper, and the corrosion resistance is almost the same as that of copper.
4. The operation is convenient and simple with no need for professionals, but can be performed only after people are simply trained by professionals.
5. The requirement for operating environment is low, and no external power source or heat source is required for welding.
