Metal Welding

The welding of metal sheets is used to obtain a permanent connection of metal parts with a continuity of the material.

The main feature of welding is the creation of monolithic structures that do not have a discontinuity of characteristics despite the presence of joints. This aspect is very important when mechanical strength of the piece uniform product is required and as well as a uniform resistance to external agents (e.g. corrosion).

According to the AWS abbreviations the main welding techniques are:

• OFW - Oxyfuel Gas Welding
• SMAW - Shielded Metal Arc Welding
• SAW - Submerged Arc Welding
• GMAW - Gas Metal Arc Welding (MIG/MAG)
• GTAW - Gas Tungsten Arc Welding (TIG)
• PAW - Plasma Arc Welding
• ESW - Electorslag Welding
• EGW - Electorgas Welding
• LBW - Laser Beam Welding
• EBW - Electron Beam Welding
• RW - Resistance Welding
• FSW - Friction Stir Welding
