Welding, also known as fusion and fusion, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. In order to ensure the safety of welding production and avoid all kinds of accidents, the safety inspection related to welding production shall be carried out before welding. It can be divided into the following points:

1、 Safety inspection of welding production site

1. Necessity of safety inspection on welding production site

In the welding process, in order to ensure the smooth progress of welding production and prevent accidents in advance, the safety of the welding site must be checked.

2. Contents of safety inspection on welding production site

(1) Whether the equipment, tools and materials on the welding and cutting site are arranged in order, and there shall be no disorderly stacking on the site.

(2) Whether the welding personnel have necessary channels and whether these channels can meet the needs of welding production.

(3) Whether the area of welding site is wide. It is required that the working area of each welder shall not be less than 4m; the ground shall be dry; the working site shall have good natural lighting or local lighting facilities.

(4) Check whether the gas welding rubber tube and the rubber tube, the electric welding cable, or the gas welding rubber tube and the electric welding cable are intertwined.

(5) Within a certain range of welding operation site, there shall be no combustible and explosive materials.

(6) Indoor operation ventilation shall be good, and arc protection screen shall be provided between multi site welding operations.

(7) The outdoor climbing welding site shall meet the requirements; when welding in trenches, tunnels, inspection wells, pipe sections and semi closed sections, check whether there is explosion and poisoning hazard.

2、 Safety inspection of tools

1. Tool safety inspection for welding operation

(1) Welding tongs: the function of welding tongs is to clamp welding rod and conduct welding power. Before welding, check the conductivity and heat insulation of the welding tongs, whether the welding rod is firmly clamped and whether it is convenient to replace the welding rod.

(2) Welding mask: the welding mask is a kind of shielding tool to prevent the splashing, arc and other radiation from damaging the welder's face and neck during welding. There are two types: hand-held type and helmet type.

(3) Hammer: check whether the hammer head is loose, and prevent the hammer head from hitting people during use.

(4) Flat shovel: before use, check whether there is any flying injury or crack on the edge.

2. Precautions for automatic welding

(1) Before welding, the mechanical and electrical equipment shall be checked. The grounding device, protective device, limit device, etc. shall be kept in good condition. The mechanical transmission part must be flexible and lubricated with oil. The electrical circuit shall be well insulated. A kind of

(2) During operation, pay attention to the surrounding environment and the connection of the mechanical power line, and do not arbitrarily remove the bolt from the control box to the welding head of the transformer. A kind of

(3) When cleaning up welding slag, use small broom and other tools, do not touch with hands, and wear protective glasses. A kind of

(4) During welding, the conductor shall be placed well to avoid slag burning. If the conductor is damaged and exposed, it shall be bound or replaced in time to prevent leakage. A kind of

(5) After welding, the welding handle shall be placed properly, especially to prevent short circuit between the wire feeding button of the welding handle and the welding object. A kind of

(6) When welding in the narrow box room, good ventilation and supervision shall be provided, and measures shall be taken in time in case of problems.
