The goal of controlling welding stress is to reduce its peak value and make it evenly distributed. The stress measures of Shandong automatic welding equipment mainly include the following:
1. Reduce the welding restraint: try to weld the weld under a small restraint, and try not to control the deformation by rigid fixation, so as not to increase the welding restraint.
2. Adopt reasonable welding sequence: under the assembly condition of more welds, the welds with large shrinkage shall be welded first and then the welds with small shrinkage; Weld the weld with large restraint and can not shrink freely first, and then weld the weld with small restraint and can shrink freely.
3. Reduce the weld size: under the condition of meeting the design requirements, the weld size and layer height shall not be increased, and the concept that the larger the weld is, the safer it is shall be changed.
4. Hammering method to reduce welding residual stress: after each layer of weld bead is welded, use a round head slag hammer or electric hammering tool to evenly knock the weld metal to produce plastic extension deformation and offset the local tensile stress borne by the weld after cooling.
5. Derusting by shot blasting machine: the welding stress of components is offset by uniform knocking of steel shot.
6. Reduce the rigidity of weldment and create conditions for free shrinkage.
