Electric welding machine advantages: electric welding machine using electric energy, electric energy will be instantly converted to heat, electricity is very common, electric welding machine suitable for work in a dry environment, do not need too many requirements, because of the compact size, simple operation, easy to use, faster, welded welded seams after welding and other advantages are widely used in various fields.

Special for the requirements of high strength parts especially practical, can instantly will be the same kind of metal materials (can also be connected to dissimilar metals, just welding method is different) permanent connection, weld after heat treatment, and the parent material of the same strength, sealing is very good, which to the storage of gases and liquids containers to solve the sealing and strength of the problem of the manufacture of containers.

Disadvantages of electric welding machine: electric welding machine in the use of the process of welding machine will produce a certain amount of magnetic field around the arc burning will produce radiation to the surrounding area, the arc has infrared, ultraviolet and other light species, and metal vapors and soot and other hazardous substances, so the operation of the operation must be done to provide adequate protection measures.

Welding is not suitable for high-carbon steel welding, due to welding weld metal crystallization and segregation and oxidation processes, for high-carbon steel, welding performance is poor, easy to crack after welding, resulting in hot and cold cracks. Low-carbon steel has good welding performance, but the process should also be operated properly, rust removal and cleaning is more cumbersome, and sometimes the weld will appear slag cracks pores biting and other defects, but properly operated will reduce the production of defects.
