Welding Expert.


The welding technician is an expert in techniques and applications of this technology. There are two large groups of welding techniques: autogenous and electric. The first uses the flame produced as a heating source by the combination of oxygen and acetylene or butane gas, while the second is produced by an electric arc between the electrode and the part to be welded. Depending on the inert gas and the electrode used, there are several types of electric welding (MIG, MAG, TIG, ...).

Electric welding is a very common production process in machining companies without scrap extraction, assembly of metal structures, automotive, machinery manufacturing... Most companies use electric welding for maintenance work. Electric welding equipment ranges from manual to robotic, depending on operations to be performed. In many manufactures (mainly in the car industry) the welding process is automated, basically by means of CNC robots (robotic welding). In this case the welding process is completely automated, both in the welding operation and piece holding. This type of welding is usually used to perform point and arc welding techniques, where it is applied on a large scale. Furthermore, autogenous welding is mainly used in boiler making, shipbuilding and metal cutting (oxy-cutting) operations.

This professional generally depends on the workshop manager, plant manager or production manager.
