MIG/MAG wire

In consumable electrode shielded gas arc welding (also known as MIG or MAG arc welding), an electric arc is created between the end of the continuously advanced solid wire electrode and the workpiece. The arc and the welding melt are protected by a neutral or active gas jet. The process is suitable for most materials and welding consumables are available for a wide range of metals.

Due to the method of the process, MIG/MAG welding is more productive than MMA, since productivity is reduced if the welder stops and a new electrode is inserted into the electrode holder, and slag loss is also saved. So the mass of weld metal deposited per unit time is much greater.

In MMA welding, there is also material loss from the fact that the end of each electrode must be discarded. About 65% of every kg of coated electrode purchased becomes part of the welding (the rest will be waste / slag).

The use of solid wire raised this efficiency up to 80% and this efficiency was increased to 95% by the appearance of powder coated wire. MIG/MAG is a versatile welding process, with which the welding material can be used with very good output and in all welding situations.

The process is widely used for thin, medium and thick steel structures, as well as for aluminum alloy structures that require a relatively high proportion of manual work.

With the appearance of powder-coated wire, its application is also increasing in the field of shipbuilding, oil and gas offshore industry.

Powder-coated wires have also given robotic welding a new impetus, as these wires are very good at high-speed welding, which would be very difficult to do by hand.
