Safety essentials of the hottest electric welding

Safety essentials of electric welding and cutting work

whether welding and cutting operations can be carried out safely and smoothly is of great importance. It is necessary to make all safety preparations before welding and cutting operations. Welding and cutting projects, regardless of their size, must carefully make all safety preparations before hot welding and cutting. Key points:

check whether welding and cutting equipment are complete and easy to use to prevent accidents of welding and cutting equipment. Before hot work at work every day, first check whether it is an ideal testing equipment welding and cutting equipment with simple operation, convenient use and stable performance. Mainly check whether the acetylene generator or electric welding machine operates and operates normally, whether a certain water level is maintained in the flashback preventer (including post type flashback preventer), and whether the plunger pump on the oxygen cylinder has high rated pressure, compact structure The advantages of high efficiency and convenient flow regulation include whether the force meter is firm, whether the jet welding and cutting torch have suction, whether there is air mixed in the acetylene generator, and whether there are unsafe factors in the laying of the arc connecting wire

carry out safety inspection on the welding and cutting operation site, remove all kinds of combustibles, and prevent fire accidents caused by welding and cutting sparks splashing. In particular, the welding and cutting temporarily determined should be thoroughly inspected, and the welding and cutting operation area should be delimited. If necessary, safety ropes should be pulled at the operation site. The safe distance between combustible materials and welding and cutting operations is generally not less than 10 meters, but the specific situation should be treated in a "body", such as the size of wind force, the difference of wind direction, the location of operation, welding or cutting, etc. In short, the area where welding and cutting sparks cannot splash to the place where combustibles are stacked shall be regarded as the boundary

it is an extremely important safety preparation work before welding and cutting operations to check the internal structure of welding and cutting parts, remove inflammables and explosives inside welding and cutting parts, and prevent explosion accidents. Especially for the welding and cutting parts brought temporarily, we must not think that the work is simple and blindly weld and cut. We must eliminate all kinds of unsafe factors before hot work welding and cutting

check the connecting parts of welding and cutting parts to prevent fire accidents caused by heat conduction and heat diffusion. For example, when welding and cutting various metal pipelines of buildings, it is necessary to find out what pipelines are, whether there are combustible gases and other substances in the pipelines, and whether there is pressure. If there are combustible substances and pressures in the pipelines, welding and cutting must not be carried out. Even if there is no dangerous pipeline, it is also necessary to find out the direction of the pipeline and whether the part to which the pipeline leads is dangerous. Welding and cutting can be carried out with hot work only after it is determined that the dangerous factors have been found out and eliminated. Welding and cutting in various ships should pay more attention to the impact of thermal conductivity and thermal diffusion on other parts of the hull. If welding and cutting operations are required due to work needs, practical safety measures must be taken for the affected parts before welding and cutting, Only then can hot work be carried out for welding and cutting

in the temporarily determined welding and cutting places, acetylene generators, oxygen cylinders or electric arc welding equipment should be placed in appropriate positions. These equipment should be kept a certain safe distance from the welding and cutting operation site. Obvious signs such as inaccessible fire and prevention of electric contact should be set beside the acetylene generators and electric welding machines, and safety ropes should be blocked to prevent irrelevant personnel from approaching these 8. Cooling medium: ethanol or other non freezing liquid equipment. The wire of arc welding shall be laid on the channel without combustibles

find out the fire-fighting facilities and equip necessary fire-fighting equipment to prevent fire accidents. Welding workers should learn the basic methods of extinguishing fire, understand the basic knowledge of extinguishing fire, and learn the use of various fire extinguishers

workers engaged in welding and cutting operations must wear work clothes. In winter, the cotton padded clothes for keeping out the cold must be sewed well, and the cotton wadding must not be exposed to prevent smoldering and fire in case of sparks
