A welder (TIG, MAG) welds demanding pressure vessels in modern production facilities. The welding includes BW and FW joints in different positions. The welder knows how to weld in all positions, preferably with more experience with metals over 10 mm thick. The material used is mainly carbon steel and stainless steel, but also, for example, titanium. All welding seams are checked with ultrasound. The welder must be able to read technical drawings and perform the installation independently.
