【Summary Description】 Low carbon steel how to weld? Low carbon steel has low carbon content and good plasticity, and can be made into various joints and components. In the welding process, it is not easy to produce hardened tissue, crack tendency is small. At the same time, it is not easy to produce pores. It is the best Welding materials. Low carbon steel can be welded by gas welding, manual arc welding, automatic submerged arc welding, gas shielded welding and other methods, and good welded joints can be obtained. When using gas welding, do not heat for a long time, otherwise the grains in the heat-affected zone will easily become larger. When the joint stiffness is high and the ambient temperature is low, the workpiece should be preheated to 100~150 ℃ to avoid cracking. How to weld medium carbon steel? Due to the high carbon content of medium carbon steel, the weld and its heat affected zone are prone to hardening and cracking, so it should be preheated to about 300 ℃ before welding and slowly cooled after welding. Gas welding, manual arc welding and gas shielded welding can be used for welding. Welding should be used with good crack resistance, such as 506 joints and 507 joints.
