Welding stainless steel

In addition to being specialists in welding black steel, Hosta Industries have set up a department that focuses exclusively on welding stainless steel.

Here, we ensure that your stainless workpieces are handled correctly, and we are in constant contact with our stainless steel suppliers – which means that you get to enjoy an optimised process. When it comes to stainless steel welding, we understand the importance of safe welding and proper handling of the product. We focus solely on offering workpieces of the highest quality – which is why all our employees are certified in the typical weld types.

In the welding of stainless steel, MIG/MAG welding, TIG welding, stud welding and spot welding is possible.

You can read more about the different welding methods below, or contact us for advice.

We also offer welding black steel and aluminium.

The MIG and MAG welding methods are short for Metal Inert Gas and Metal Active Gas. This means that the shielding gas used for the weld is what determines whether the weld is MIG or MAG welding. Often, MIG & MAG welding is referred to as CO2 welding.

MIG & MAG welding creates an arc of light between a workpiece and the filler material, which is continuously fed from a spool.
The filler material acts as an electrode.

The choice of shielding gas is made based on the material to be welded, as well as the filler material used.
Here, the gas consumption is between 10 and 20 l/minute, depending primarily on the type of arc used in the weld; short arc or spray arc.

The MIG/MAG welding process is one of the common welding processes in both manual welding as robotic welding.

The TIG welding method is short for Tungsten Inert Gas and is almost always used when welding thin materials.

TIG welding is the typical welding method for a finer quality because incredibly little, or even no weld spatter is formed when using this method. TIG welding is used for welding black steel, aluminium and stainless steel. Compared to CO2 welding, TIG welding has a smaller output.

However, TIG welding results in a smaller weld and a different visual result. This is due to this welding method gives the welder the option to not use filler metal/welding wire when welding two materials together.

The stud welding method is used only to weld pins and bolts on to workpieces. Hosta Industries has the option of stud welding in M4 – M12.

For stud welding, welding studs and pins are used, as well as a stud welding machine. Here, a short and strong current impulse melts a specially formed point on the bolt. This results in a welded on bolt.

For stud welding, there is no need for laser cutting, perforation or similar of the workpiece.

The spot welding method is widely used in the automotive industry, where two plate surfaces are welded together. Spot welding is used not only in the automotive industry but also in other contexts. The process is also widely used in the production of woodburning stoves.

Copper electrodes are used, which are particularly useful for the various welding jobs. The electrodes are used by pressing the electrodes against the plates, while a high current impulse is applied for a short period. This melts the plates together.

This welding method is especially good for welding aluminium, zinc, steel sheets and hot-dip galvanised steel.

Hosta Industries also offers pickling as a supplement to welding your workpiece. Pickling is useful for changing a workpiece’s surface. To that purpose, electrothermic cleaning with a carbon fibre brush and liquid is used to keep the weld clean. During the cleaning, among others things, the blackness resulting from the weld disappears, and the liquid is subsequently flushed off the workpiece. This is a gentle process that ensures that the workpiece is not scratched.

As a subsequent process, the unit can polish the welds, which means that you can place, for example, a logo or a desired text on the workpiece.

We offer pickling in collaboration with some of Denmark’s leading partners.
