Welding method of steel structure

    1, manual arc welding: This is a commonly used welding method. Manual electric arc welding equipment is simple, flexible and convenient to operate, suitable for welding in any space position, especially suitable for welding short welding seam. But the production efficiency is low, the labor intensity is big, the welding quality has a great relationship with the technical level and the mental state of the welder.

    2, automatic or semi-automatic submerged arc welding (arc welding): submerged arc welding is a kind of arc welding method of arc burning under the flux layer. The movement of welding wire feeding and welding direction is controlled by special agencies, called submerged arc automatic welding. The welding wire is sent to a specialized agency, while the movement of welding direction is called semi submerged arc welding by workers.
