Spawanie stali kwasoodpornej MIG/MAG, TIG. Grubość do 20mm. Welding of carbon steel using MAG, MIG and TIG methods Low-alloy steels are alloys to which additional components have been added, such as manganese, chromium or nickel, in quantities not exceeding 2% of a single component. Considering the specific properties and intended use, we distinguish three groups of materials: steels with increased strength , low-alloy steels for power engineering and steels for thermal improvement. Carbon Steel Welding Procedures It is worth noting that the increase in the content of carbon and alloying elements worsens the weldability of steel and carries the risk of cold cracks. Before starting welding, our specialists will assess the weldability of steel based on the chemical composition and the Ce equivalent. On this basis, they will determine whether they are dealing with easily weldable steel, with limited weldability or difficult to weld. We also use the hardness criterion for the initial assessment of weldability. In the case of low-alloy steels with a higher carbon equivalent, we use specific technological measures, such as: increased linear arc energy, preheating and low-hydrogen welding processes.
