Submerged Arc Welding (or SAW) is an extremely efficient automated welding method from mild steel to the toughest steels. The SAW method is the most productive, and offers a deposition rate generally varying between 8 kg/h (17 lbs/h) and 100 kg/h (220 lbs/h) in specific applications with several wires.

MIG/MAG - GMAW welding is a welding process that is ideal for automation. Sahel Gaz has many years of experience in this regard and over the years we have become pioneers in robotic welding and other applications in Senegal and the sub-region.

The TIG (tungsten under inert gas) or GTAW (tungsten arc under gas shielding) process uses a refractory solid tungsten electrode. The electrode, the arc and the area surrounding the molten weld pool are shielded from the atmosphere by an inert gas screen. Which makes it one of the safest welding processes around.

Friction welding is a method primarily for joining aluminum and copper alloys without the use of an exposed arc. This method provides a bond similar in structure to the base metal with minimal distortion in a single pass for a plate thickness of up to more than 50 mm (2").

Hybrid laser welding offers manufacturers the ability to fulfill orders while improving productivity and quality over conventional welding processes. The HLAW method makes it possible to weld thin materials at welding speeds three to five times higher than those of MIG/MAG - GMAW welding.
