Computation and Analysis of the Influence of Transient Thermal Tensioning Intensity on Welding Distortion in Butt Joint with 304L Stainless Steel

doi:10.3901/JME.2021.06.060

Abstract

Abstract: Welding induced buckling is common during thin plate welding and seriously affects the production efficiency and manufacturing cost of thin plate welding structures. 304L stainless steel thin plate butt joints are taken as the research object. The pattern of saddle shape is observed through experiments, and the magnitude of out-of-plane deformation is measured using a three-dimensional optical scanning system. Subsequently, a thermo-elasto-plastic(TEP) finite element analysis is carried out to represent the process of welding distortion. The numerical predicted results based on large deformation theory are in good agreement with the measured data, and are different from the results based on small deformation theory, which verifies the occurrence of welding induced buckling. Meanwhile, in order to achieve transient thermal tensioning, two symmetrical additional heat sources moving synchronously with welding arc are applied to the region, which is away from welding line with the distance of 110 mm. In addition, the influence of the intensity of the additional heat source is studied. The results show that transient thermal tensioning decreases the compressive force during heating process and the tensile force during cooling process in the weld from base material, which will reduce the longitudinal self-constraints of the base material as well as reducing welding induced buckling. When the maximum temperature of the additional heating area reaches 195 ℃ and 273 ℃, the maximal deflection of points along the weld is decreased by 80% and 72%, respectively, and the welding induced buckling is almost controlled.
