A welding platform work surface should not have rust, scratches, bumps and other effects of the appearance of defects.
  2, the working surface of the Welding Material should not have sand holes, pores, cracks, slag inclusions and shrinkage of casting defects. Casting surface should be thoroughly cleared the sand, and the surface is smooth, solid paint, repair blunt edge of each tax.
  T-slot on opposite sides of the surface of the plate should install the handle or lifting position of the set, the screw hole or cylindrical hole. Set the lifting position should consider to minimize the deformation caused by lifting.
  4, the Welding Wires  stability of the treated and demagnetization.
