1、铆焊加工时的电器、内燃机、电机、空气压缩机等的使用应有完整的防护外壳,一、二次接线柱处应有保护罩。
1. The use of electrical appliances, internal combustion engines, motors, air compressors and so on in the riveting and welding process should have a complete protective shell, and there should be a protective cover at the one or two junction.
2、焊按操作及配合人员必须按规定穿戴劳动防护用品。并必须采取防止触电、高空坠落、瓦斯中毒和火灾等事故的安全措施。
2. Welding operators and personnel must wear protective clothing according to the regulations. Safety measures must be taken to prevent accidents such as electric shock, high altitude fall, gas poisoning and fire.

3、现场使用的电焊机,应高有防雨、防潮、防晒的机棚,并应装设相应的消防器材。
 
3. The welder used on site should be equipped with rainproof, moisture-proof and sunproof machinery shed, and the corresponding fire-fighting equipment should be installed.
4、施焊现场10m范围内,不得堆放油类、木才、氧气瓶、乙炔发生器等易燃、易爆物品。
4. Within the 10m scope of the welding site, no inflammable and explosive materials such as oil, wood, oxygen bottles, acetylene generators can be stacked.
5、当长期停用的电焊机恢复使用时,绝缘电阻不得小于0.5MΩ,接线部分不得有腐蚀和受潮现象。
5. When the long-term outage of the welding machine is resumed, the insulation resistance shall not be less than 0.5M, and the wiring part shall not be corroded or damped.
6、电焊机导线应具有良好的绝缘,绝缘电阻不得小于1MΩ,不得将电焊机导线放在高温物体附近。
6. Welding machine conductor should have good insulation, insulation resistance should not be less than 1M, welding machine conductor should not be placed near high temperature objects.
7、电焊钳应有良好的绝缘和隔热能力。电焊钳握柄必须绝缘良好,握柄与导线连接应牢靠,接触良好,连接处应采用绝缘布包好并不得外露。操作人员不得用胳膊夹持电焊钳。
7, the electric welding clamp should have good insulation and heat insulation ability. The grip handle of electric welding clamp must be well insulated, the grip handle should be firmly connected with the conductor, good contact, the connection should be wrapped with insulating cloth and not exposed. The operator shall not hold electric welding pliers with their arms.
8、电焊导线长度不宜大于30m。当需要加长导线时,应相应增加导线的截面。当导线通过道路时,必须架高或穿过防护管内埋设在地下;当通过轨道时,必须从轨道下面通过。当导线绝缘受损或断股时,应立即更换。
8, the length of electric welding wire should not be greater than 30m. When lengthening conductor is needed, the cross section of conductor should be increased correspondingly. When a conductor passes through a road, it must be erected or buried underground through a protective pipe; when passing through a track, it must pass under the track. When the conductor insulation is damaged or broken, it should be replaced immediately.
9、对承压状态的压力容器及管道、带电设备、承载结构的受力部位和装有易燃、易爆物品的容器严禁进行焊接和切割。
9. It is strictly forbidden to weld and cut the pressure vessels and pipes, the charged parts, the bearing parts of the bearing structure and the containers equipped with inflammable and explosive materials in the pressure state.
10、焊接铜、铝、锌等有色金属时,应通风良好,焊接人员应戴防毒面罩、呼吸滤清器或采取其他防毒措施。
10. Welding copper, aluminum, zinc and other non-ferrous metals, should be well ventilated, welding personnel should wear anti-virus mask, breathing filter or take other anti-virus measures.
11、当需要焊受压容器、密封容器、油桶、管道、沾有可燃气体和溶液的工件时,应先消除容器及管道内丈夫力,消除可燃气体和溶液,然后冲洗有毒、有害、易燃物质;对存有残余油脂的容器,应先用蒸汽、碱水冲洗,并找开盖口,确认容器清洗干净后,再灌满清水方可进行焊接。
11. When a pressure vessel, a sealed container, a tank, a pipe, a pipe, a combustible gas and a solution need to be welded, the husbands' force in the container and pipe should be removed first, the combustible gas and solution should be eliminated, and then the toxic, harmful and flammable substances should be washed, and the container with residual oil should be washed with steam and alkaline water first and found open. Cover the mouth and make sure that the container is cleaned before filling with clear water.
12、当焊接预热焊件温度达150~700℃时,应设挡板隔离焊件发出的辐射热,焊接人员应穿戴隔热的石棉服装和鞋、帽等。
12. When the temperature of the welding preheating weldment reaches 150~700 C, the radiant heat from the baffle isolating weldment should be set, and the welders should wear insulated asbestos clothing and shoes and caps.
13、高空焊接或切割时,必须系好安全带,焊接周围和下方应采取防火措施,并应有专人监护。
13. Safety belt must be fastened when welding or cutting at high altitude. Fire prevention measures should be taken around and below the welding and special guardianship should be taken.
14、雨天不得在露天电焊。在潮湿地带作业时,操作人员应站有铺有绝缘物品的地方,并应穿绝缘鞋。
14, the rain day must not be in the open welding. In wet areas, operators should have insulated goods and wear insulating shoes.
15、应按电焊机额定焊接电流和暂载率操作,严禁过载。
15, the rated welding current and temporary load rate of electric welder shall be operated strictly without overload.
16、当清除焊缝焊渣时,应戴防护眼镜,头部应避开敲击焊渣飞溅方向
16. When removing welding slag, wear protective glasses. The head should avoid the direction of percussion slag splashing.
