Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize, ablate or reach the ignition point. At the same time, the molten material is blown away by a high-speed airflow coaxial with the beam, thereby cutting the workpiece. open. Nowadays, CO2 pulse laser is generally used, and laser cutting is one of the thermal cutting methods.
plasma cutting
Plasma arc cutting is a processing method that uses the heat of a high-temperature plasma arc to locally melt (and evaporate) the metal at the cut of the workpiece, and uses the momentum of high-speed plasma to remove the molten metal to form the cut.
Argon arc welding
Argon arc welding is a welding technology that uses argon as a protective gas. [1] Also known as argon gas shielded welding. It is to pass argon protective gas around the arc welding to isolate the air from the welding area and prevent oxidation of the welding area.
Argon arc welding technology is based on the principle of ordinary arc welding, using argon gas to protect metal welding materials, and using high current to melt the welding materials into a liquid state on the base material to be welded to form a molten pool, so that the metal to be welded and the welding material are A welding technology that achieves metallurgical bonding of materials. Since argon gas is continuously supplied during high-temperature molten welding, the welding material cannot come into contact with oxygen in the air, thus preventing the oxidation of the welding material. Therefore, stainless steel and iron hardware metals can be welded .
