1. Due to the good welding performance of hot-rolled carbon steel coil flat products, the welding requirements are not too high in the case of not thick plates, and the AC spot welding machine can meet the welding requirements. 2. If the equipment cost allows, try to use the medium frequency inverter spot welding machine to spot weld the mil steel plate. The welding effect is better, the nugget and the welded joint will be more perfect. 3. There are cold-rolled steel plates and hot-rolled steel plates. Cold-rolled steel plates do not need special cleaning before welding, while hot-rolled steel plates must remove impurities such as oxidation, rust, and oil stains on the surface. 4. If the capacity of the spot welding machine used allows, it is recommended to use hard specification welding to reduce the influence of thermal diffusion on the product and also reduce the deformation of the product.
After heat treatment, the hardness and wear resistance can be improved.
The hardness is appropriate during annealing, and the machinability is good.
Carbon steel plate has good toughness and plasticity, so it has a certain elongation.
It has good welding performance and heating performance, so it is widely used in steel structure construction engineering.
