The stainless steel pipe welding is one of the most demanding processes in the industrial sector.
At CORVATS ESPECIALS SL (COES), based in Terrassa (Barcelona), we have the experience,
the equipment and technical precision required to ensure clean, strong and durable joints.
Technical challenges in stainless steel welding
Stainless steel requires a high level of control during welding. Temperature, cleanliness and protection
The use of inert gas is a decisive factor to avoid material contamination or loss of mechanical properties.
Even a small deviation in the process can cause deformations or defects in the weld seam.
Importance of the controlled environment
During TIG or MIG welding, oxygen and humidity can generate oxides or inclusions. For this reason, at COES we apply
pre-cleaning protocols and protection with noble gases that preserve the purity of the stainless steel, maintaining its finish.
aesthetics and corrosion resistance.
Thermal control and deformation
Stainless steel has a high thermal expansion, which can cause internal stresses and deformations.
Thermal control by means of thermal control techniques orbital TIG welding or the use of controlled pulses allows reducing
heat input and maintain the geometry of the tube.
Advanced applied techniques
At COES we use automated systems and precise welding procedures that ensure uniformity and repeatability.
on each part. This is essential in industrial production and in sectors that require very tight tolerances.
Selection of the appropriate welding method
Depending on the thickness, type of alloy and function of the tube, we select the most appropriate technique: TIG, MIG or resistance welding.
Each method offers specific advantages, and the experience accumulated by our technical team allows us to adapt the process to the specific needs of our customers.

FAQs on stainless steel pipe welding
Why is cleaning before welding stainless steel so important?
Stainless steel can easily become contaminated with particles or oils. If welded without proper cleaning,
pores or inclusions are produced that weaken the bond. In COES we perform mechanical and chemical cleaning before the process.
to guarantee pure and resistant joints.
What is the difference between TIG and MIG welding on stainless steel?
TIG welding offers greater control and aesthetic finish, ideal for thin thicknesses and visible beads.
MIG, on the other hand, is more productive in thicker or structural parts. At COES we apply both methods
according to project requirements.
How to avoid deformation in thin tubes?
It is controlled by reducing the heat input and using pulse or orbital TIG welding techniques.
In addition, the tooling and fixtures maintain the geometry during the process, ensuring perfect alignment.
Which sectors require stainless pipe welding?
Automotive, food, energy, architecture and industrial machinery are some of the main ones.
All share the need for clean, durable and aesthetically accurate welds.
