Introduction
1、Arc welding
Arc welding is a kind of welding process in which two contacting metals are melted and fused by burning the metal with a current. Arc welding includes carbon dioxide gas arc welding, argon arc welding, submerged arc welding and so on. Arc welding has the advantages of simple operation, high welding efficiency and good welding quality.
2、Melting welding
The melting welding is a direct fusion welding process,
which melts the base metal and the filler material into a molten pool to realize the welding. The melting welding process
includes gas welding, tungsten inert gas welding, plasma welding,
etc. The melting welding has the advantages of good adaptability, simple operation, high welding speed and wide application range.
3、Thermal pushing welding
4、Electric melting welding
5、Plasma welding
Welding process
The welding process includes the preparation before welding, welding and the cleaning after welding, etc.
1、Before welding
Before welding, we need to do a good job in the preparation work, which includes surface treatment, groove processing, fit-
up inspection and joint design selection.
b) Groove processing: According to the requirements of the welding process, the groove is machined out, and the size and shape of the groove meet the requirements of the welding process.。
