Understand the different welding techniques

The different welding techniques, their advantages and our training

At the heart of the industrial piping and welding field, there are several techniques that meet various needs.

We will present the different techniques, their advantages and the different training courses that we offer.

1. The coated electrode arc welding

Coated electrode arc welding is one of the most common techniques used. This technique works with an electric arc (a metal rod covered with an enrobing) and the part to be welded. The arc will melt the electrode, which will become a bonding metal between the two pieces. The coating produces a protective gas that protects the weld against air oxidation.

This process requires good skills. It is used in high-tech fields.

Benefits :

  • Can be used outdoors
  • Suitable for various metals (steel, stainless steel, cast iron, etc.)

2. MIG/MAG welding

MIG/MAG welding is a semi-automatic process that uses a continuous weld metal until melting. An electric arc will form between the wire and the solder, melting the wire to weld the metals together.

The term MIG means “Metal Inert Gas”, which is the welding under an inert gas. Uses an inert gas (such as argon) that does not react with the metal, ideal for materials sensitive to oxidation such as aluminum.

The term MAG means “Metal Active Gas”, meaning solder under active gas. Uses an active gas (such as CO ), which reacts with the metal to promote melting, mainly used for welding steel. The MAG has a direct effect on the profile of the cord as well as on the mechanical properties.

The choice between MIG and MAG depends mainly on the type of metal to be welded and the protection requirements of the melt.

Benefits :

  • Welding fast enough and efficient
  • Less slag than arc weldin
  • Requires less cleaning

3. TIG welding

TIG welding is a very precise technique that uses a tungsten electrode and an inert gas to protect the weld. The filler metal must be added manually as a filler metal. TIG welding is mainly used for projects with high quality clean finishes.

Benefits :

  • Technique requiring dexterity
  • Allows for qualitative welds with excellent properties
  • No projections
  • Welds with good characteristics

4. Torch welding

Flame welding, also known as oxyacetylene welding, uses a flame that produces a mixture of gases to heat and melt the metal.

Benefits :

  • Versatile
  • Widely used for repairs
