Welding is a joining method in which two separated solids are joined together by the bonding force between atoms by appropriate physical and chemical methods,
Objects Welded: Solid
Metal_metal
Metal_Non-Metal
non-metal_non-metal
Essence of welding: relying on the bonding force between atoms
Welding means:
Heating: fusion welding, brazing (materials with a lower melting point than the base metal are used as filler metals)
Pressurization: cold pressure welding
Heating + pressure: resistance welding, diffusion welding
Welding methods: fusion welding, pressure welding (using physical effects such as friction, diffusion and pressure), brazing.
Fusion welding: gas welding, aluminothermic welding, electroslag welding, electron beam welding, laser welding, resistance spot welding, resistance seam welding (rolling electrode), arc welding (melting electrode arc welding, non-melting electrode arc welding)
Melting electrode arc welding: electrode arc welding MMA, submerged arc welding SAW, molten electrode argon arc welding MIG/MAG, CO2 gas shielded welding, stud welding
Non-melting electrode arc welding: argon tungsten arc welding GTAW TIG, plasma arc welding PAW.
