The results show that maximum weld longitudinal residual tension and transverse recurring stress were respectively reduced by 12.3% and 13.6% when likened to no permanent magnet field, furthermore have blind hole testing method measure welding left over stress, Check measurement and simulation beliefs were basically consistent.

Arc heat supply model of GTAW under the permanent magnetic field had been established, furthermore consider actual attributes of components varying with the temp and the influence transformation, through the method of killing or triggering elements therapy like as burning or solidification by welding pool, 3D FEM simulation analysis for the temperatures gradient and left over stress size distribution to GTAW welded joints likened to on permanent magnetic field or not. Summary: Intending at adscititious permanent magnet field impact GTAW arch, decrease the optimum welding residual which by arc shape end up being changed, avoid the temperatures excessive focus on welding pool, reduce temp gradient and therefore on.
