Welding safety inspection notes of gi seamless pipe

Gi seamless pipe during the welding process of the fluid pipe, due to various reasons, there may be some hidden dangers. Therefore, regular safety inspections are necessary. Below, let me introduce the precautions for welding safety inspection.

Welding site, equipment safety inspection:
1. Check whether the equipment, tools, and materials for the welding and cutting work points are arranged neatly and not in a random manner.
2. Check whether the welding site maintains the necessary channels, and the width of the vehicle channel is not less than 3m, and the pedestrian channel is not less than 1.5m.
3. Check whether all welding hoses and welding cables are entangled with each other. If they are entangled, they must be separated. Whether the cylinders are removed from the work site after use or not, various gas cylinders at the work site must not be placed horizontally.
4. Check whether the welding work area is sufficient. The welding work area should not be less than 4m2. The ground should be dry and the work place should have good natural lighting or local lighting.
5. Check whether the various combustible and explosive articles are cleared within 10m around the welding cutting site. If it cannot be cleaned, take reliable safety measures, such as spraying wet or covering with waterproof cover, wet sack, and asbestos cloth. Indoor operations should check whether the ventilation is good. When multiple welding operations or mixed with other types of work, protective screens should be set up between the workstations.
6, The outdoor job site to check the following content: whether the site to meet the safety requirements for climbing work; in the trench, tunnels, inspection wells, pipe sections and semi-enclosed sites, etc., should strictly check for the risk of explosion and poisoning, should use equipment ( Such as explosion testers, toxic gas analyzers, etc., for inspection and analysis, prohibit inspection with open flames and other unsafe methods. For open holes and trenches in the vicinity, apply asbestos plates to prevent sparks from entering.

Safety inspection of fixtures:
1, Welding clamp. Before welding, check whether the welding clamp and the welding cable joint are firm and the jaws are in good condition.
2, Masks and eye protection lenses. Check for tightness and light leakage.
3, Angle grinder. To check the wheel rotation is normal, there is no leakage phenomenon, whether the wheel has been fastened firmly, whether there are cracks, damage, to prevent the use of debris fly out of the wound.
4, Hammer. To check if the hammer is loose, avoid the hammer flying out of the wound during the strike.
5, Flat shovel, dumplings. Should check whether the edge of the fly, cracks, if any should be promptly removed to prevent the use of debris flying out of wounds.
6, Fixtures. All kinds of fixtures, especially fixtures with screws, should check whether the screws on them are flexible. If they have rust, they should be rusted and lubricated, otherwise they will lose their function during use.
