There are many ways to weld metals. How to find the most suitable welding method for you? I believe everyone is very smart. They will consider the cost, efficiency, product quality, quality of welded products, mechanical life, environmental protection and other aspects. These small series will not be written in detail for the time being. Let's talk about the basic methods first.
 
1. from the broad category, there are three methods namely
 
1. Pressure welding
2. Fusion welding
3. Brazing
 
1) Pressure welding is subdivided:
 
① Resistance butt welding
Resistance spot welding, projection welding and seam welding
③ Cold welding
④ Ultrasonic welding
⑤ Explosive welding
⑥ Forging and welding
⑦ Diffusion welding

2) Fusion welding can be subdivided:
 
① Arc welding: plasma arc welding, atomic hydrogen welding, argon arc welding, gas shielded welding, submerged arc welding, stud welding, electrode welding.
② Gas welding: oxygen hydrogen gas welding, oxygen acetylene gas welding, air acetylene gas welding.
③ Thermite welding
④ Electroslag welding
⑤ Electron beam welding
⑥ Laser welding
 
 
3) Brazing can be subdivided:
 
① Flame brazing
② Induction brazing
③ Furnace brazing
④ Salt bath brazing
⑤ Electron beam brazing
