Welding

Welding

It forms an important part for the productive process. We have approved and experienced welders; and of equipment of welding TIG, MIG, AUTÓGENA, PLASMA And MICROPLASMA. We currently have a ship to house high-tonnage jobs.
Of the processes that exist, the most used in a machining workshop are usually:

TIG

Also called GTAW (for tungsten arc): it uses an electric arc as an energy source that is established between the non-consumable electrode and the piece to be welded with the protective cover of the inert gas. When filling material is used, it is provided by the use of rods, in the same way as in oxyacetylene welding.
During the process, the TIG torch must be connected to the negative pole (-) and the ground clamp to the positive pole (+).
The TIG process can be used for the welding of all materials, including aluminum magnesium and materials sensitive to oxidation such as titanium.
It is a mostly manual process, used when we have to make the pieces on the side and then finish the job with some welding.

MIG

Also named as GMAW (by metal arc and gas).

When using this welding to machine, an electric arc is established between the electrode, (which has the form of a continuous wire) and the piece that is welded.

The gas is inert, in the case that the gas is active, the welding will be known as MAG. There are different ways to perform the soldier with MIG, manually, automatically or semiautomatically.

It can be used for small and medium thicknesses in steel structures and aluminum alloys. It can be used for steel applications, but also for non-ferrous materials.

Submerged arc welding

Submerged arc welding is an electric arc welding procedure in which the welding arc is not seen burning between the endless electrode and the part. The electric arc and the fusion bath are covered by a granulated powder.

The slag formed by the powder serves to protect the weld zone from the influence of the atmosphere.
High-performance welding procedures such as submerged arc welding are applied, above all, mechanized or automated.
