Gas Metal Arc welding is better known as MIG or MAG welding.
The technique employs a shielding gas, argon being the most popular, which simplifies the welding process.
MIG welding (MIG stands for Metal Inert Gas) leaves a lot of black carbon that can cause welds to become brittle (porosity).
The MAG welding process (MAG stands for Metal Active Gas) uses a mixed shielding gas of carbon dioxide and argon to avoid this phenomenon. The ”burn-off” process and the electrical power from the arc both generate heat in the MAG weld. MAG therefore produces somewhat more heat compared to MIG welding.

This chair is finished using the MIG welding technique. Quite often projects may require that you adapt different techniques before pieces are joined. This will ensure the best result and cost efficiency.
