冷器焊接專機的結(jié)構(gòu)形式很多，使用范圍廣，長與焊件變位機械相配合，完成各種焊接作業(yè)。操作人員在使用冷器焊接專機的時候是有一些注意事項的，大家知道嗎？下面山東自動焊接設(shè)備廠家就帶你一起來看看。

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.

冷器焊接專機的特點

Features of special welding machine for cooler

①焊接夾具通常是焊接電源二次回路的組成部分，因此絕緣和傳導(dǎo)是設(shè)計中注意的問題。

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用于焊接夾具，主要承受重力焊接，焊接應(yīng)力和夾緊力。有些還要在組裝時承受錘子，焊接夾具也承受鍛造力。

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焊接夾具，焊接結(jié)構(gòu)尺寸的安裝尺寸增加，重量增加，形狀變得復(fù)雜，增加了夾具難以拆卸的難度。

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焊接過程中，部件由于冷卻而被焊接加熱或拉長或縮短，為了減少焊接變形，一些零件的夾具要求可以是抗變形或剛性夾緊焊接應(yīng)力，也允許某些部件在一定方向上可以自由伸展。因此，焊接夾具不適用于所有部件的剛性夾緊。

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由于焊件通常由多個簡單部件焊接，并且這些部件的組裝和定位在焊接夾具中依次進行，因此它們的定位和夾緊是分開的。

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.

使用冷器焊接專機要注意的事項

Matters needing attention when using a special welding machine for cooler

①電焊鉗過熱后不可以浸在水中冷卻后使用；

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

②裝卸乙炔氣瓶或石油氣瓶應(yīng)注意輕拿輕放，不得拋、碰、滑、滾等劇烈震動；

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進行二氧化碳氣體保護焊時，作業(yè)前二氧化碳氣體預(yù)熱15分鐘；

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

④焊機二次測把線及地線長度不超過30米；

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

⑤交流電焊機空載電壓不得超過80伏；

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

⑥焊接完成后，應(yīng)切斷閘斷電，將地線和把線分開，并在離開現(xiàn)場前確保熔渣的火星是熄滅狀態(tài)；

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焊機一次測的電源線長度不超過5米；

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

⑧嚴(yán)禁用金屬管、金屬腳、軌道、結(jié)構(gòu)鋼筋等金屬物體代替地線。

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