Guide to the various types of welding

Welding is a joining operation that creates the chemical-physical union of two elements, with or without filler material. This processing can be carried out using different machines and techniques: let’s see the most common types.

  • MIG / MAG welding

This type of electric arc welding is carried out with the aid of a fuse wire (with the function of a positive pole or anode) on the object to be welded (negative pole or cathode). The acronyms MIG and MAG refer to the material to be joined: a MIG (Metal Inert Gas) joint is indicated for light alloys while a MAG (Metal Active Gas) is recommended for non-alloy steels.

The peculiar traits of this type of operation are the versatility, the high productivity and ease of use: it can be carried out both manually and automatically and is widespread in most industrial sectors.

  • TIG welding

In TIG welding (acronym for Tungsten Inert Gas) the electric arc is enclosed between the cathode (infusible tungsten electrode) and the anode (element to be welded, protected by a non-oxidizing gas). High quality and precision are the specifications of this manual or automatic processing, suitable for irreversibly joining a large variety of materials.

  • Electrode welding

Simple, cheap and versatile: electrode welding is probably the most widespread and used type in the world. It is made using an electrode, composed of a core, metal rod, and its coating, consisting of a dried mixture of deoxidizing materials.

  • Laser welding

Laser welding is one of the most modern methods, particularly suitable for high production volumes. Characterized by a higher energy density, this technique is faster than the others, as well as qualitatively better; it is used in all industrial sectors.
