We distinguish several different welding methods depending on what media and devices are used in this process. Below we present all the most popular welding methods.
311-G gas welding - it is mainly used with acetylene, a temperature of up to 3100 ° C is needed to obtain the weld. This method is most often used when welding sheets with a thickness of 0.4-40 millimeters.
Electric welding - this method uses welding machines - devices that are based on the phenomenon of an electric arc, welding takes place at a temperature of up to 4000 ° C. The method is used when welding metal sheets in the range of 1-80 millimeters. Within the framework of electric welding, the following are distinguished:
- welding with coated electrodes - method 111
- submerged arc welding
- gas-shielded welding - MIG 131 (Metal Inert Gas), MAG 135 (Metal Active Gas), TIG 141 (Tungsten Inert Gas), cored wire welding
Electron welding - electron beam welding involves the use of an electron welder, in which the electron source is an electron gun.
Hybrid welding - a combination of laser welding and arc welding with a consumable electrode.
Laser welding - welding with the use of laser rays in an inert gas or air shield.
Plasma welding - a method that uses electric arc focusing and plasma, i.e. ionized gas.
Hydrogen arc welding.
Electro-gas welding.
Thermite welding.
Slag welding.
