焊接加工的安全注意及控制焊接应力措施

来源:http://www.babaluma.com/  发布时间:2022-08-09 浏览次数:

焊接加工的时,对职工说很多的即是安全问题,这是非常重要的一点内容。焊接加工时发现很多人在作业时没有做到这一点,为了让大家安全的作业。下面山东自动焊接设备厂家就来详细介绍一下焊接加工的安全注意及控制焊接应力措施相关事项。
During the welding process, it is very important to say a lot about safety to the employees. During the welding process, it was found that many people did not do this during the operation, in order to make everyone work safely. Next, Shandong automatic welding equipment manufacturer will introduce in detail the safety precautions of welding processing and the related matters of welding stress control measures.
焊接加工的安全注意
Safety precautions for welding processing
1、焊接加工请求便于操作,减少来回走动,避免不必要的折腰、踮脚动作。
1. The welding processing request is easy to operate, reduce walking back and forth, and avoid unnecessary bending and tiptoe movements.
2、定位准确可靠,避免稍有轰动便发生误动作。
2. The positioning is accurate and reliable to avoid misoperation in case of slight sensation.
3、机床设备操作件运动方向和被操作部件运动方向要符合规定,并有简便符号标志。
3. The movement direction of the operating parts and the movement direction of the operated parts of the machine tool equipment shall comply with the regulations and shall be marked with simple symbols.
4、安设必要的互锁组织,避免操作件发生不协调动作,以及多人操作时不协调出现的事故。
4. Necessary interlocking organization shall be installed to avoid uncoordinated action of operating parts and accidents caused by uncoordinated operation of multiple persons.
5、手柄、手轮、按钮的构造和摆放方位要符合规定。发动按钮应安设在机壳内或装设避免意外牵动的护环。设备在轴杆上的手轮、手柄,在主动进刀时,会随轴滚动伤人,因而应设备主动脱出设备。
5. The structure and placement orientation of handle, hand wheel and button shall meet the requirements. The start button shall be installed in the cabinet or equipped with a guard ring to avoid accidental pulling. The handwheel and handle on the shaft of the equipment will roll with the shaft and hurt people when the tool is actively fed, so the equipment should be taken out of the equipment actively.
上述五点就是焊接加工的安全注意事项。正确的进行焊接加工是保障焊接加工人员安全和生产效率的根本。
The above five points are the safety precautions for welding processing. Correct welding processing is the fundamental to ensure the safety of welding workers and production efficiency.

控制焊接应力措施
Measures to control welding stress
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 constraint: try to make the weld weld weld under a small constraint. Try not to control the deformation by rigid fixation to avoid increasing the welding constraint.
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 with many welds, the weld with large shrinkage shall be welded first, and then the weld with small shrinkage shall be welded; Weld the weld with large restraint and free contraction first, and then weld the weld with small restraint and free contraction.
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: on the condition that the design requirements are met, the weld size and layer height should not be increased, and the concept that the larger the weld, the safer the weld.
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 the welding of each layer of weld bead is completed, use a small round head slag hammer or an electric hammering tool to evenly strike 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. Use shot blasting machine to remove rust: evenly knock the steel shot to offset the welding stress of the component.
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 contraction.
控制焊接应力的目标是降低其峰值使其均匀分布,措施主要有以上几种,您可以作为参考内容了解了解,当然如果您有什么疑问没解决的话就来我们网站http://www.babaluma.com咨询吧。
The goal of controlling welding stress is to reduce its peak value and make it evenly distributed. There are mainly the above measures. You can learn about them as a reference. Of course, if you have any questions, please come to our website http://www.babaluma.com Consult.
