焊接设备上的电机、电器、空压机等应按有关规定执行,并有完整的防护外壳,一、二次接线柱处应有保护罩。
The motor, electric appliance, air compressor, etc. on the welding equipment should be carried out according to the relevant regulations, and have a complete protective shell. There should be a protective cover at the one or two junction.
 
现场使用的电焊机应设有可防雨、防潮、防晒的机棚,并备有消防用品。
The electric welding machine used in the field should be equipped with rain proof, moistureproof, sunscreen and fire protection equipment.
 
焊接时,焊接和配合人员必须采取防止触电、高空坠落、瓦斯中毒和火灾等事故的安全措施。
In welding, the welding and matching personnel must take safety measures to prevent accidents such as electric shock, high altitude falling, gas poisoning and fire.
 
严禁在运行中的压力管道、装有易燃易爆物品的容器和受力构件上进行焊接和切割。
It is strictly prohibited to weld and cut the pressure pipes, vessels equipped with inflammable and explosive materials and force members in operation.
 
焊接铜、铝、锌、锡、铅等有色金属时,必须在通风良好的地方进行,焊接人员应戴防毒面具或呼吸滤清器。
When welding copper, aluminum, zinc, tin, lead and other non-ferrous metals, it must be carried out in a well ventilated place, and the welder should wear a respirator or a respirator.
 
在容器内施焊时,必须采取以下措施:容器上必须有进、出风口并设置通风设备;容器内的照明电压不得超过12V,焊接时必须有人在场监护,严禁在已喷涂过的油漆或塑料的容器内焊接。
The following measures must be taken when welding the container. There must be inlet and outlet and ventilation equipment on the container. The lighting voltage in the container should not exceed 12V. When welding, there must be someone on-site monitoring, and it is forbidden to weld in the painted paint or plastic container.
 
焊接预热焊件时,应设挡板隔离焊件发出的辐射热。
When welding preheated weldments, the radiant heat from the baffle isolating weldment should be set.
 
高空焊接或切割时,必须挂好安全带,焊件周围和下方应采取防火措施并有专人监护。
When welding or cutting at high altitude, a safety belt must be hung. Fireproof measures and special guardianship should be taken around and below the weldment.
 
电焊线通过道路时,必须架高或穿入防护管内埋设在地下,如通过轨道时,必须从轨道下面穿过。
When the wire is passed through the road, it must be high or buried inside the protective tube, such as through the track, it must pass through the track.
 
接地线及手把线都不得搭在易燃、易爆和带有热源的物品上,接地线不得接在管道、机床设备和建筑物金属构架或轨道上,接地电阻不大于4Ω。
The ground and handlebars shall not be attached to inflammable, explosive and heat source articles. The grounding wires must not be connected to pipelines, machine tools and building metal frames or tracks, and the grounding resistance is not greater than 4 ohms.
 
雨天不得露天电焊。在潮湿地带作业时,操作人员应站在铺有绝缘物品的地方并穿好绝缘鞋。
There is no surface electric welding on rainy days. When working in a damp area, the operator should stand in the place of insulation and wear insulating shoes.
 
长期停用的电焊机,使用时,须检查其绝缘电阻不得低于0.5MΩ,接线部分不得有腐蚀和受潮现象。
When used for a long time, the electric welding machine must be checked that the insulation resistance should not be less than 0.5M Omega. The connection part must not have corrosion and damp phenomenon.
焊钳应与手把线连接牢固,不得用胳膊夹持焊钳。
With the hand line welding tongs should be firmly connected, no arm clamping pliers.
 
清除焊渣时,面部应避开被清的焊缝。
When cleaning slag, the face should avoid the clear weld.
 
在载荷运行中,焊接人员应经常检查电焊机的温升,如超过A级60°C、B级80°C时,必须停止运转并降温。
During the load operation, the welder should often check the temperature rise of the welding machine, such as over a class a 60 C, B level 80 C, must stop running and cooling.
 
施焊现场的10m范围内,不得堆放氧气瓶、乙炔发生器、木材等易燃物。
In the 10m range of the welding site, inflammable materials such as oxygen gas cylinder, acetylene generator and wood shall not be stacked.
 
作业后,清理场地、灭绝火种,切断电源,锁好电闸箱,消除焊料余热后,方可离开。
After the operation, cleaning up the site, the fire extinction, cut off the power supply, the lock gates box, eliminating solder heat, can leave.
