焊接加工的時，對職工說很多的即是問題，這是非常重要的一點內(nèi)容。焊接加工時發(fā)現(xiàn)很多人在作業(yè)時沒有做到這一點，為了讓大家的作業(yè)。下面山東自動焊接設備廠家就來詳細介紹一下焊接加工的注意及控制焊接應力措施相關(guān)事項。

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.

焊接加工的注意

Safety precautions for welding processing

1、焊接加工請求便于操作，減少來回走動，避免不必要的折腰、踮腳動作。

1. The welding processing request is easy to operate, reduce walking back and forth, and avoid unnecessary bending and tiptoe movements.

2、定位準確可靠，避免稍有轟動便發(fā)生誤動作。

2. The positioning is accurate and reliable to avoid misoperation in case of slight sensation.

3、機床設備操作件運動方向和被操作部件運動方向要符合規(guī)定，并有簡便符號標志。

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、安設必要的互鎖組織，避免操作件發(fā)生不協(xié)調(diào)動作，以及多人操作時不協(xié)調(diào)出現(xiàn)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、手輪、按鈕的構(gòu)造和擺放方位要符合規(guī)定。發(fā)動按鈕應安設在機殼內(nèi)或裝設避免意外牽動的護環(huán)。設備在軸桿上的手輪、手柄，在主動進刀時，會隨軸滾動傷人，因而應設備主動脫出設備。

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.

上述五點就是焊接加工的注意事項。正確的進行焊接加工是保障焊接加工人員和生產(chǎn)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.

控制焊接應力措施

Measures to control welding stress

1.減小焊接拘束度：盡量使焊縫在較小拘束度下焊接，盡量不用剛性固定的方法控制變形,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.采取合理的焊接順序：在焊縫較多的組裝條件下，應先焊收縮量較大的焊縫，后焊收縮量較小的焊縫；先焊拘束度較大而不能自由收縮的焊縫，后焊拘束度較小而能自由收縮的焊縫。

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.減小焊縫尺寸：在滿足設計要求的條件下，不應加大焊縫尺寸和層高，要轉(zhuǎn)變焊縫越大越的觀念。

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.錘擊法減小焊接殘余應力：在每層焊道焊完后，立即用圓頭敲渣小錘或電動錘擊工具均勻敲擊焊縫金屬，使其產(chǎn)生塑性延伸變形，并抵消焊縫冷卻后承受的局部拉應力。

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.采用拋丸機除銹：通過鋼丸均勻敲打來抵消構(gòu)件的焊接應力。

5. Use shot blasting machine to remove rust: evenly knock the steel shot to offset the welding stress of the component.

6.降低焊件剛度,創(chuàng)造自由收縮的條件。

6. Reduce the rigidity of weldment and create conditions for free contraction.

控制焊接應力的目標是降低其峰值使其均勻分布，措施主要有以上幾種，您可以作為參考內(nèi)容了解了解，當然如果您有什么疑問沒解決的話就來我們網(wǎng)站http://www.meangen.com咨詢吧。
