Steel welding

The stainless steel welding process in Minifaber

Stainless steel is a special alloy that has important attributes such as corrosion resistance and high hygiene standards, which is why it is widely in demand for the food and medical sectors. For more than 50 years, Minifaber has been welding stainless steel according to each specific request. Click here to learn more about stainless steel welding. 
Stainless steel welding is an important process because of the quality of this material, and can be done using different methods: MIG/MAG, TIG or Laser welding. 
Let's look at the differences between them and their respective applications. 
Stainless steel is one of the most widely used materials in numerous sectors, from food and pharmaceuticals to mechanical and vending. The demand for finished and semi-finished parts made of stainless steel is due to its properties, primarily corrosion resistance. 
Stainless steel welding is therefore one of the fundamental metalworking procedures: let's see how it is done and what methods are most effective.

Stainless steel welding: TIG, MIG/MAG and Laser

Stainless steel can be welded with similar materials as well as with ferrous materials. Stainless steel welding must take account of the type of steel being welded, and must ensure that the corrosion resistance qualities remain the same, even after welding.

• The choice comes down to three different methods:
• TIG welding
• MIG/MAG welding
• Laser welding

Stainless steel TIG welding
Stainless steel welding using the TIG (Tungsten Inert Gas) process is suitable when it is necessary to create joints with impeccable quality while minimizing deformation. Not only that, the quality of this process makes it ideal for welding very thin pieces of stainless steel. 
TIG welding is done with an electric arc that strikes between an infusible Tungsten electrode and the part through a shielding atmosphere of ionized inert gas. 

Stainless steel MIG/MAG welding 
On the other hand, when a very high production rate is required and the thicknesses are higher, the most suitable stainless steel welding method is MIG (Metal Inert Gas)/ MAG (Metal Active Gas) welding, in which the filler material is melted directly under the cover of gas. In addition to high-productivity, the MIG/MAG method of stainless steel welding is also perfect when application flexibility is required. 

Capacitor discharge, short arc, electric resistance welding for stainless steel 
These welding processes are widely used for welding pins and studs. 
Capacitor discharge welding is used extensively on stainless steel to weld pins and studs without leaving deformation while offering excellent aesthetic appearance. 
It is used in the small appliance industry. 
Short arc welding offers more significant welded joints when the aesthetic aspect is less important. It is used in the electromechanical industry and in metalwork in general. 
The projection form of resistance welding is also used to weld custom-made pins and bushes. 

Laser welding 
Finally, when talking about welding stainless steel with a laser process, we are referring to the process that offers the best quality in terms of deformation reduction and weld penetration combined with execution speed.

Stainless steel welding with Minifaber

At Minifaber, we also perform stainless steel welding using the above methods. Our service is among the most flexible in that we can:

• Perform welding on semi-finished stainless steel parts, or welding to assemble complex finished products
• Produce small batches or large quantities of parts, even staggering fabrication over several periods of the year.

In all stainless steel welding processes, our primary goal is to produce stable, strong and excellent quality joints that are suitable for a wide variety of markets: from medical to food, including all applications for the electromechanical and household appliance sectors.
