pipe welding tips
A set of manual welding equipment, a handle type Angle grinder, an electric hammer, a plane ruler.1. Check and debug equipment to ensure normal operation;2. Prepare 44.01402 shreds for drying at 300℃-350℃ for one hour.Welding process 1. Assembly assemble the vertebral body and large-caliber straight-seam welded pipe together according to the requirements of the drawing, and divide the large-caliber straight-seam welded pipe into 8 equal parts on average.2, welding because the large straight seam welding pipe is thicker, the groove is larger, so the use of segmental symmetry, multilayer welding.Quality requirements weld strength at least to base strength.The surface of welding seam is smooth and smooth, without defects such as burning through, air hole, welding leak, slag inclusion, undercut and incomplete welding.Residual height is less than 2mm.1. Use]506 welding rod for surfacing and small current welding.Strictly follow the welding process.2. After each welding position, the horizontal ruler should be used to clamp a large amount of deformation of the flat surface of the straight seam welding pipe.
