Automatic welding
Hot wire TIG process
We have state-of-the-art technology for automatic radial hot wire TIG welding.
The TIG process is the most demanding welding process, requiring experienced welders; while productivity is low, it is used for products in which a very high-quality weld and a beautiful aesthetic appearance are required. With automatic welding, we can guarantee a high quality of welds and their uniformity and repeatability.
The hot wire TIG process is relatively new and uses a constant speed oscillating welding wire feed generated by a patented four-cylinder drive system. Wire feeding is up to 200% faster, allowing welding with a smaller heat-affected zone, with excellent mechanical and corrosion properties, and reducing the possibility of cracks.
Lower energy input also causes the formation of a smaller amount of welding gases and significantly reduces the oxidation of the weld joint.
Hot wire TIG welding is performed with the help of a mobile console and a rotating welding positioner that moves the welder evenly. Together, this ensures an automated TIG welding process.
The achieved weld quality is suitable both for the food industry and demanding pressure vessels, where X-ray inspection of the weld is required. The TIG process is intended for the food and pharmaceutical industries. Our welding processes are duly certified (WPQR).

Automatic device for longitudinal welding VAR-STROJ L – 2000/D-2500 LCD/MIG
The welding machine is intended for longitudinal welding of cylindrical welds. Welding can be performed using the TIG or MIG/MAG process. The root of the weld is protected with a backing strip with a protective gas-blowing system. We use certified shielding gases for welding.
We can weld stainless steel from 2 mm to 10 mm on the machine. The minimum diameter of the weld is 300 mm, and the maximum is 3000 mm.
The achieved weld quality is suitable both for the food industry and demanding pressure vessels, where X-ray inspection of the weld is required. The TIG process is intended for the food and pharmaceutical industries and MIG/MAG for pressure vessels. Our welding processes are duly certified (WPQR).

Automatic device for radial welding VK-YZ-1GM
The machine is intended for circular MIG/MAG welding. The welding console is 2. 6/1. 5 m. The circular movement is achieved with the help of the ON-5T turning device on which the welder is placed. The welding console allows us to move the welding head on the Y-axis and the Z-axis to more easily reach the place of the circular weld, which we follow while the welder moves on the turning device.
We can weld stainless steel from 2 mm to 10 mm on the machine. The minimum diameter of the weld is 300 mm, and the maximum is 2500 mm. We use certified shielding gases for welding.
The achieved weld quality is suitable also for demanding pressure vessels, where an X-ray inspection of the weld is required. Our welding processes are duly certified (WPQR).

Manual welding
We perform welding with various welding sources. We have several different welding machines at our disposal, suitable for the TIG welding process and the MIG/MAG process.
Our experienced and certified welders are specially trained to weld stainless steel. When welding, we use the TIG process, which is suitable for the most demanding industries, such as the food and pharmaceutical industries. The welding process is prescribed and supervised by our welding engineer IWE, who is responsible for ensuring that all welding sites are properly prepared and that the resulting weld meets the requirements of our loyal customers.
Manual welding of stainless steel can be performed for materials and pipes with a thickness of 1 mm or more. Welds can be without or with added welding material (welding wire). When welding, we use duly certified protective welding gases.
Our welders are also trained in the MIG process, mainly used for construction or thicker materials.
Welds are regularly checked by visual inspection and leak tests. If necessary, we also carry out more demanding non-destructive tests, such as penetrant inspection, X-ray of welds and pressure tests.
