冷器焊接专机的结构形式很多，使用范围广，长与焊件变位机械相配合，完成各种焊接作业。操作人员在使用冷器焊接专机的时候是有一些注意事项的，大家知道吗？下面山东自动焊接设备厂家就带你一起来看看。

There are many structural forms of cooler welding machine, which can be used in a wide range. It can complete all kinds of welding operations by cooperating with weldment displacement machinery. Do you know that the operators have some precautions when using the special machine for welding the cooler? Now, Shandong automatic welding equipment manufacturer will show you.

冷器焊接专机的特点

Features of special welding machine for cooler

①焊接夹具通常是焊接电源二次回路的组成部分，因此绝缘和传导是设计中注意的问题。

① The welding fixture is usually a part of the secondary circuit of the welding power supply, so insulation and conduction are the problems to be paid attention to in the design.

②用于焊接夹具，主要承受重力焊接，焊接应力和夹紧力。有些还要在组装时承受锤子，焊接夹具也承受锻造力。

② It is used for welding fixture, which mainly bears gravity welding, welding stress and clamping force. Some also bear the hammer during assembly, and the welding fixture also bears the forging force.

③焊接夹具，焊接结构尺寸的安装尺寸增加，重量增加，形状变得复杂，增加了夹具难以拆卸的难度。

③ Welding fixture, the installation size of welding structure size increases, the weight increases, and the shape becomes complex, which increases the difficulty of fixture disassembly.

④焊接过程中，部件由于冷却而被焊接加热或拉长或缩短，为了减少焊接变形，一些零件的夹具要求可以是抗变形或刚性夹紧焊接应力，也允许某些部件在一定方向上可以自由伸展。因此，焊接夹具不适用于所有部件的刚性夹紧。

④ During welding, parts are heated or stretched or shortened by welding due to cooling. In order to reduce welding deformation, the fixture of some parts can be anti deformation or rigid clamping welding stress, and some parts are also allowed to stretch freely in a certain direction. Therefore, the welding fixture is not suitable for rigid clamping of all parts.

⑤由于焊件通常由多个简单部件焊接，并且这些部件的组装和定位在焊接夹具中依次进行，因此它们的定位和夹紧是分开的。

⑤ Since weldments are usually welded by multiple simple parts, and the assembly and positioning of these parts are carried out in turn in the welding fixture, their positioning and clamping are separated.

使用冷器焊接专机要注意的事项

Matters needing attention when using a special welding machine for cooler

①电焊钳过热后不可以浸在水中冷却后使用；

① Electric welding tongs cannot be used after being immersed in water and cooled after overheating;

②装卸乙炔气瓶或石油气瓶应注意轻拿轻放，不得抛、碰、滑、滚等剧烈震动；

② When loading and unloading acetylene cylinders or petroleum cylinders, pay attention to handle them with care, and do not throw, touch, slide, roll and other violent vibrations;

③进行二氧化碳气体保护焊时，作业前二氧化碳气体预热15分钟；

③ When carbon dioxide gas shielded welding is carried out, carbon dioxide gas shall be preheated for 15 minutes before operation;

④焊机二次测把线及地线长度不超过30米；

④ The length of the secondary measuring line and ground wire of the welding machine shall not exceed 30 meters;

⑤交流电焊机空载电压不得超过80伏；

⑤ The no-load voltage of AC welding machine shall not exceed 80V;

⑥焊接完成后，应切断闸断电，将地线和把线分开，并在离开现场前确保熔渣的火星是熄灭状态；

⑥ After welding, cut off the power supply, separate the ground wire from the connecting wire, and ensure that the spark of molten slag is extinguished before leaving the site;

⑦焊机一次测的电源线长度不超过5米；

⑦ The length of the power line measured by the welder at one time shall not exceed 5 meters;

⑧严禁用金属管、金属脚、轨道、结构钢筋等金属物体代替地线。

⑧ It is strictly forbidden to replace the ground wire with metal objects such as metal pipes, metal feet, tracks, structural reinforcement, etc.
