山东自动焊接设备应力的措施主要有什么?

来源:http://www.tayfsk.com/  发布时间:2021-08-30 浏览次数:

控制焊接应力的目标是降低其峰值使其均匀分布,山东自动焊接设备应力的措施主要有以下几种:

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.减小焊接拘束度:尽量使焊缝在较小拘束度下焊接,尽量不用刚性固定的方法控制变形,以免增 大焊接拘束度。
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.采取合理的焊接顺序:在焊缝较多的组装条件下,应先焊收缩量较大的焊缝,后焊收缩量较小的焊缝;先焊拘束度较大而不能自由收缩的焊缝,后焊拘束度较小而能自由收缩的焊缝。
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.减小焊缝尺寸:在满足设计要求的条件下,不应加大焊缝尺寸和层高,要转变焊缝越大越安 全的观念。
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.锤击法减小焊接残余应力:在每层焊道焊完后,立即用圆头敲渣小锤或电动锤击工具均匀敲击焊缝金属,使其产生塑性延伸变形,并抵消焊缝冷却后承受的局部拉应力。
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.采用抛丸机除锈:通过钢丸均匀敲打来抵消构件的焊接应力。
5. Derusting by shot blasting machine: the welding stress of components is offset by uniform knocking of steel shot.
6.降低焊件刚度,创造自由收缩的条件。
6. Reduce the rigidity of weldment and create conditions for free shrinkage.
