Welding is a manufacturing technique for joining two pieces of metal by fusion. So far, the welding process is the most famous application for joining several techniques of metal structures such as bridges, pressure vessels, automobiles, ships and rails. During the welding process, the welder must protect his body for safety and health reasons from dangerous risks, which will be done with personal protective equipment and other equipment. Welders must be aware of the risks associated with the welding process, namely physical risks and chemical risks. Say no to plagiarism.

Many danger factors can arise for the welder in the welding area. The welder can have knowledge of the potential hazards of a welding process and address them by walking through the work area, equipment, materials and consumables to be used. Physical hazards are caused by electricity, radiation, heat, flame, fire, explosion, noise and magnetic field. One of the potential dangers of a physical hazard is electricity. Electrical hazard occurs due to electric shock or electrocution. Electric shock during the welding process can cause death or serious burns. If the welder comes into contact with electrical energy, he will suffer shock and fall. So the welder does not work in a wet area, broken insulation wire, electric current cable around the body, welding near the welding cable, etc. Make sure the electrical installation is in good condition. Then the radiation from the welding process has a reason for skin burning and peeling due to the metal liquid on the welded metal is hot and contains ultraviolet when the welder does not wear the right cloth. Make sure combustible materials are kept away from the welding area, such as paper, wood, plastic and others, which may cause fire. The grinding process may cause noise and sparks. Hearing loss can be caused by dangerous noise levels, it is above 85 decibels that prolonged or repeated exposure to sounds can cause hearing loss. Safety equipment to reduce noise is earplugs or noise-canceling headphones. And sparks from grinding can cause an explosion if concentrated in the fuel tube regulator area. Finally, potential hazards related to the welding process are chemical hazards, they are caused by welding fumes, combustible gases, inert gases, gas mixtures and solvents. Welding process chemical hazards are a type of welding hazard caused by exposure to chemicals in the workplace. Exposure to chemicals in the field can cause acute or long-term negative health effects. The welding process produces smoke containing particles of various types of oxides. Fumes, such as carbon dioxide, ozone, and fumes containing heavy metals, can be hazardous to welders who do not have adequate ventilation and work procedures. When welding with a combustible gas, carbon dioxide will be produced, but a reduced flame will produce carbon monoxide. Shielding gases such as argon, helium and carbon dioxide, alone or mixed with oxygen or hydrogen,..
