For some large Weixing storage tanks, large-scale production is the need to use the way of welding splicing, then here for the welding requirements, stainless steel storage tank manufacturers below to introduce the stainless steel storage tank welding requirements are what? 1, first of all you want to weld the storage tank should meet the relevant requirements of welding process and welding materials. 2. When welding the top plate of the large Wuxi storage tank and the hemming angle steel, the main welds shall be symmetrically and evenly distributed, and the welding shall be performed in sections along the same direction. 3, first welding the inner weld, after welding the outer weld, radial long weld should adopt the seam symmetrical welding method, and by the middle

For some large Weixing storage tanks, large-scale production needs to be spliced by welding, so there are requirements for welding here,Stainless steel storage tank manufacturersThe following is a brief introduction to the welding requirements of stainless steel storage tanks?

First of all, the storage tank you want to weld should meet the relevant requirements of welding process and welding materials.

2. When welding the top plate of the large Wuxi storage tank and the hemming angle steel, the main welds shall be symmetrically and evenly distributed, and the welding shall be performed in sections along the same direction.

3. The inner weld shall be welded first, and the outer weld shall be welded later. The radial long weld shall be welded symmetrically at spaced seams, and the welding shall be performed in sections from the center to the outside.

4, before welding should check the assembly quality, remove the groove surface and groove on both sides of the 20mm range of rust, moisture and dirt, and should be fully dry.

5. When the defect depth or grinding depth exceeds 1mm, repair welding shall be carried out and polished smoothly.

6, the depth of more than 0.5 ㎜ scratches, arc scratches, welding scars and other harmful defects, should be polished smooth, polished steel plate Qianzhou reverse osmosis pump thickness should not be less than the nominal thickness of the steel plate minus negative deviation value.

7. For the welding of the tank wall, the vertical weld is welded first, and then the circumferential weld is welded. After the longitudinal weld of two adjacent circles of wall plates is welded, the circumferential weld between them is welded again. Welders are evenly distributed and welded in the same direction.

8, tack welding and welding fixture, should be qualified welder welding, arc should not be on the base metal or completed weld.

  Stainless steel storage tankThe welding requirements are the above. Only with good welding can the storage tank have good quality and will be used for a longer time.
