Blu-ray independent research and development production of steel pressure welding fixtures, the use of seamless steel tubes for the guide tube, the upper and lower fixed by manganese steel castings for special treatment, further strengthened its surface hardness and inner toughness. The clamp has a flexible operation, reliable performance, easy maintenance and easy adjustment. Suitable for advanced construction-intensive steel welding pressure welding type, widely used in walls, columns, beams, piles, floor, slope protection, bridges and other steel joints. Diameter welded steel range 12 - 36mm, 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 0.4 yuan; This machine has a compact and easy to use and flexible, welding speed and welding process is simple, reliable, high joint strength, the advantages of small investment in equipment.
