Welding is a kind of joint process method that promotes the local heating and melting of the section of the welded metal to reach the liquid state through the arc thermal effect produced by the welding equipment, so that the originally separated metal can be combined into a solid and non detachable joint. Because it is dangerous to operate, many electric welding workers have a lot of precautions during operation. The specific matters are as follows:
1. Work with certificate
Metal welding operators must receive professional safety technical training, pass the examination, and take the post with special operation certificate. Non electric welders are strictly prohibited from welding.
2. Safe operation
The welding workers shall wear welding work clothes, insulating shoes, welding gloves, protective masks and other safety protection articles during operation, and wear safety belts when working at heights.
3. Pre work inspection
Before operation, welding workers must check that inflammable and explosive materials are not allowed to be stacked within 10m around the operation site.
4. Precautions for outdoor operation
Open air operation is not allowed in rainy, snowy and windy days with force 6 or above. After rain and snow, the accumulated water and snow shall be removed before welding.
5. Check welding machine and tools
Before operation, first check the welding machine and tools, such as the insulation of welding tongs and welding cables, the protective grounding of the welding machine shell and the connection points of the welding machine, and confirm that they are safe and qualified before operation.
6. Prohibited area
It is strictly prohibited to weld and cut in the flammable and explosive gas or liquid diffusion area, the pressure pipeline in operation, the container containing inflammable and explosive articles and the stressed components.
