Welding parameters of metal oil tanks should be strictly controlled

When welding metal oil tanks, to avoid deformation of the weld seam, it is necessary to use the corresponding welding process according to the type of steel used in the tank, and strictly control the welding process parameters.

When the metal oil tank wall needs to adopt the double-sided welding and double-sided forming process, if it is not properly described, it is very easy to produce angular deformation, because when welding the outer side of the longitudinal seam, there is a gantry plate on the inner side to restrict the inward angular deformation, so as to prevent the inward angular deformation when welding the outer side, and the gantry plate needs to be removed when welding the inside, and other effective control measures are not taken, the outward angular deformation is out of tolerance.

By controlling the welding process parameters, the input of welding line energy is reduced on the premise of ensuring the welding quality, so as to reduce the angular deformation.
