(5) the Groove position welds and welding the same welding process should be adopted, by qualified Welders and welding. Tack weld should be evenly distributed, there is generally no less than 2-3, length should be to 10-15mm, uniform distribution, wall thickness of no more than 2/3. (6) the tack should ensure good penetration and fusion, and free of porosity, slag and other defects. (7) to ensure the bottom bead molding well to reduce stress concentration, tack should be a smooth transition to the base metal and welds polished at both ends should be generated. (8) unless the process or inspection required-welded, but each seam continuous welding finish, otherwise again before welding, to preheat the weld. (9) the welding arc scraped surface is strictly prohibited, without any introduction arc welding on the surface. (10) should ensure that the arc and arc welding of quality, arc should fill crater, multi-pass welding joint should be staggered. (11) Tig welding should be ventilated in advance, expired after welding should be delayed, and should ensure that the welding in the welding process melts to get effective protection of argon gas. (12) when using the multi-pass welding, weld before should be cleaned, after making sure that no defects, and again the next. (13) the weld should be a smooth transition to the base metal and weld both ends ground into slope. (14) card with the welding, the material should be identical to the base metal, and at the time of demolition cards should not damage materials and residues in the welding scar on the base metal polished fixed flush to the base metal.
