TIG welding

Although TIG welding is slower than MIG / MAG welding, it is particularly effective with clean and fine welding seams.

Area of application:

We use the procedure when we move in the decorative field or when by our customers very fine, clean welds are required.


The TIG welding process produces minimal spatter through the use of a tungsten electrode and low production of welding fume. Nonetheless, we naturally use welding fume extractors in all workplaces.
Another advantage of the TIG welding process is that the electrode does not melt during welding.

Modes of operation:

The TIG welding machine uses a tungsten electrode to melt the underlying workpiece and filler material, thereby joining several metal parts together.
From the ceramic nozzle of the TIG welding machine flows a protective gas, which surrounds the arc and the melt (the weld pool) like a bell, thus protecting it against the gases of the air - primarily oxygen.
As a rule, the inert gas argon is used in TIG welding.
Since the purity of the gas has a very high influence on the result, we always ensure that there is no draft in TIG welding.

For the welding of aluminum we use the so-called pulse welding process. In this case, a high-frequency pulse is applied to the tungsten electrode. Our welding machines have comfortable adjustment options. Thus, in addition to the ignition of the arc, the current, the gas supply and much more can be set and the device can also be switched to DC or AC.

Pickling and passivating stainless steel

Pickling of stainless steel is used for corrosion resistance of non-rusting steels, because even stainless steel in untreated form can rust after welding or mechanical processing.
Pickling is a surface treatment with the help of chemicals, such as acid or lye. The aim of the process is to change the outer layer of the material and thus improve its corrosion resistance.
Pickling is always required when the optimum surface condition for corrosion resistance is no longer ensured, e.g. due to: Formation of tarnish due to welding or grinding, residues of weld spatter or also deposits of metal oxides.
After the previous pickling process, the stainless steel parts are provided with a passivation layer. This layer serves as corrosion protection for the stainless steel.

Stud welding

Arc stud welding ("stud welding") is suitable as a particularly economical welding method for joining pin-shaped metal parts such as welding studs or threaded studs with metallic workpieces such as metal sheets, profiles and pipes.
Here at FACO we work with different stud welding systems of different makes. For mass production, we usually create devices to manufacture the products accurately, quickly and efficiently for our customers.
