Reinforced pressure on the welding machine is developed to improve the company repeatedly development for welded steel construction and advanced intensive pressure welding type, widely used in walls, columns, beams, piles, floor, slope protection, bridges and other steel joints. Diameter welded steel range 12 - 38mm, suitable for horizontal, vertical reinforcing steel in any direction such as welding, applicable to domestic I - 3 level and imported steel. Steel welded joints with a diameter of 25mm 4kg savings than lap steel, welding costs only 0.3 yuan; The machine has compact and flexible and easy to use, welding speed and welding process is simple, reliable, high joint strength, the advantages of small investment in equipment. Reduce the project cost with docking function, improve construction quality, improved working conditions.
