Welding

• The MAG (Metal Active Gas) method is a process of arc welding with a consumable electrode in a shield of chemically active gases or gas mixtures. The consumable electrode is a solid or powder wire, which also serves as a binder. In MAG welding processes, carbon dioxide or gas mixtures containing: argon, oxygen, carbon dioxide and others are used as shielding gases.

• The MIG (Metal Inert Gas) method is an arc welding process with a consumable electrode in the form of a solid wire in a shield of inert gases. As in the MAG method, the wire also serves as a binder (so-called electrode wire). The MIG welding process uses noble shielding gases such as argon and helium and their mixtures.

Advantages:
• good quality of welds,
• high process efficiency,
• possibility of welding in all positions,
• high work stability,
• possibility of welding materials with a wide range of thicknesses.

Defects:
• the appearance of welding spatter,
• the need to use shields when welding in open spaces,
• tendency to stick in welded joints,
• the need to prepare the edges of welded elements.

The TIG method is an arc welding process with a non-consumable electrode in an inert gas shield. The gases used to shield the welding area in the TIG method are: argon, helium or their mixture (similarly to the MIG method).

Advantages:

• no chips,
• ability to work in various positions,
  possibility of joining virtually all metals and their alloys,
• great control over the welding process,
• welding elements of different thickness.
