welding method of tank wall
for the welding of tank wall, the longitudinal weld should be welded first, and then the circumferential weld. when the longitudinal weld of two adjacent rings of wall plates is welded, the circumferential weld between them should be welded. the welders should be evenly distributed and welded along the same direction. at the same time, when the panel is assembled, a gap is set for each panel. after the longitudinal seam welding shrinkage deformation is corrected, cutting and spot welding are carried out according to the circumference.
the longitudinal weld of tank wall is welded by argon arc butt welding, and the outer weld is formed at one time, which makes the outer tank weld more beautiful; the inner welding seam is filled and covered by manual arc welding, and polished after welding. when manual welding is used, the welding root should be cleaned before welding to ensure the quality of weld.
argon arc butt welding is also used for the welding of tank wall girth weld. the outer weld is formed at one time, and the inner weld is overlaid by manual arc welding and polished after welding. when manual welding is used, the welding root should be cleaned before welding to ensure the quality of weld. when welding circumferential welds, welders shall be evenly distributed and weld in the same direction.
