Welding is a process of physical joining of materials by melting and fusing the contacting metal surfaces. Different materials require using appropriate welding methods.
MIG/MAG WELDING
Welding by means of a consumable electrode shielded by inert (MIG) or active (MAG) gases is the most commonly used method of welding.
TIG WELDING
Welding by means of a non-consumable solid tungsten electrode shielded by inert gases, such as argon or helium, or their mixtures.
WELDING OF PLASTICS
This is the process of welding in a stream of hot gas (gaseous heat medium) using welding rods as the binder.
