Metal welding

Another way of working with metals is to weld them. The essence of welding is to create a firm connection between two different metal components.

Metal welding

We weld every day at CENTES. We focus on welding parts made from steel, stainless steel, and aluminium alloys. Local companies, major engineering companies, construction companies, large automotive and aerospace companies from around the world trust us.

All components that need to be connected are welded by oxy-fuel welding, spot welding and by MIG, MAG and TIG welding. Our work does not end with welding. We can further process welded components. You can also request CNC machining and painting components.


We provide metal welding

We have been joining metals by welding at CENTES from the very beginning.

Our experienced welders ensure high-quality: 

  • Oxy-fuel welding
  • Spot welding
  • MIG/MAG welding.

Oxy-fuel welding

Oxy-fuel welding is one of the oldest fusion welding methods. This is also occasionally called autogenous welding. A mixture of acetylene and oxygen is most often used for oxy-fuel welding. This mixture reaches a flame temperature of up to 3200 °C in the right ratio, which is also sufficient for welding steel. Hydrogen or propane can also be used for oxy-fuel welding. However, the flame temperature is lower.

We usually use oxy-fuel welding for steel parts, but this method can also be used for soldering (both steel and non-ferrous metals, but also silver, for example) and oxy-fuel cutting. However, oxy-fuel welding is relatively demanding. This requires great skills on the welder’s part, who must heat the welded surfaces of the base material with a torch in one hand and add welding wire to the weld pool with the other hand. Therefore, we do not perform it as often as other welding methods. In accordance with our Code of Conduct, we pay maximum attention to operational safety in regard to oxy-fuel welding. When working, we always protect ourselves with suitable protective equipment.

Ask us about oxy-fuel welding

Due to the demands on the welder’s skills, oxy-fuel welding is one of the most demanding welding methods. This method can also be used for steel welding, soldering, and cutting.

Spot welding

Spot welding is the most commonly used type of resistance welding. It is used for joining two superimposed materials, e.g., steel sheets, joining wires into netting, etc. In spot welding, the joined materials are pressed together by two electrodes, where an electric current passes through. We provide both direct and indirect spot welding.

We usually use electrodes made from copper, cobalt and cadmium alloy, copper, silver and cadmium or copper, nickel, and silicon. The main advantage of spot welding is the high strength of welds, which are about the size of electrodes. Spot welding is mostly used in series production, e.g., in bodywork production, and in small series operations. That is why we mostly weld steel parts for the French car company s.n.o.p. We are happy to weld what you need.

We offer high-quality spot welding

Spot welding is the most widely used type of resistance welding. It is used to weld thin sheets and connect wires into grilles in the automotive industry.

MIG, MAG, TIG welding

We also provide arc welding with a melting electrode in a protective atmosphere. However, our customers know it and demand it simply as MIG/MAG welding. Both welding methods differ from each other by the shielding gases used. We weld in the shielding inert (MIG) gas or active (MAG) gas. There is also a difference in additional materials.


The biggest advantage of the welding method with a melting electrode in a protective atmosphere is the semi-automatic mode for feeding additional material (welding wire). Thanks to it, we can more easily create a weld bead and control a weld pool. This type of welding is extremely popular among our customers. We also provide TIG welding with the help of a non-melting electrode and shielding inert gas.

We can perform MIG, MAG and TIG welding

We know that any finished product is only as good as its weakest part. That is why we consider that there is no difference between welding for a small family business and TGV.

We use the following welding methods:

  • MIG
  • MAG
  • TIG

Our services

Technical preparation of production

Technical preparation of production (TPP) means detailed technological procedures and activities preceding the production of the ordered component.

Metal cutting

Cutting means machining of a metal workpiece using a machine tool. Metal chips are formed during cutting.

Chipless technologies

Chipless machining methods do not use material removal by mechanical work. Unlike cutting, they produce virtually no chips.


Painting is the final stage of metal surface treatment. In our modern paint shop, we provide powder and wet coating on delivered components.

Electrical equipment production and assembly

We do not focus exclusively on metalworking. We also offer these services for our customers so that they have no need to go elsewhere in terms of electrical equipment production and assembly.

Cutting tools and assembly jigs production

We can produce special cutting tools for sheet metal processing on hydraulic or manual presses. All we need is drawings.
