Weldingis a technique of manufacture to join two piece of metal by fusion.
Up to now,welding process is the most familiar application to joining multi techniques ofmetallic structures for instance bridges, pressure vessels, automobiles, ships,and rails. In welding process, the welder must to protect their body for safetyand health from risk of hazardous which will be done with personal protectiveequipment and other equipment. The welders should be overcome about hazardousin a welding process which are physical hazards and chemical hazards. Firstly,a physical hazard is a representative or fortune which would be effect of risk tothe welder with direct contact or no. Many factors of hazards may occur to the welderin the weld area, the welder may have a knowledge about the potential hazards ina welding process be solved with get through the work area, equipment, material and consumables to be used. The physicalhazards are caused by Electricity, radiation, heat, flames, fire, explosion,noise and magnetic field.
Oneof the potential hazard in a physical hazard is electricity. The electricityhazard occur due to electric shock or electrocution. The electric shock inwelding process may bring out death or severe burns, if the welder contact withelectric energy, the welder will results shock and fall. So, the welder do notworks in wet area, broken insulation wire, carrying electric current cablearound the body, weld close to the welding cable, etc. Make sure that theelectrical installation is in good condition. Thenthe radiation from welding process have a reason to skin burning and peeling byreason of the metal liquid on the weld metal is hot and contain ultraviolet whenthe welder not wear the right cloth.Ascertain the combustible materials are kept away from welding area such aspaper, wood, plastic and others which will built a fire. Ongrinding process can results noise and sparks.
Hearing loss can be caused byhazardous noise levels, it is at or above 85 decibels that long or repeatedexposure to sounds can cause hearing loss. The safety equipment to reduce noiseis ear plugs or ear muff. And the sparks from grinding can bring out explosion,if concentrated to fuel tube regulator area. finally,potential hazards in welding process are chemical hazards, they are cause bywelding fumes, fuel gases, inert gases, gas mixtures, and solvents.
Chemicalhazards in the welding process are a type of welding risk that caused byexposure to chemicals in the workplace. Exposure to chemicals in the field mayoccur acute or long-term negative health effects. Weldingprocess produce smoke that comprising particles of various types of oxides.Fumes, such as carbon dioxide, ozone, and fumes containing heavy metals, can bedangerous to the welders lacking proper ventilation and workplace procedure. Whenwelding with a fuel gas will produce carbon dioxide, but if a reduced flamewill produce carbon monoxide. Shielding gases such as argon, helium and carbondioxide, either alone or in mixtures with oxygen or hydrogen can also affecthealth when not following proper work procedures such as working in a room withgood air circulation. Inthis research article, the potential hazards may experience as the welder in thewelding process are physical hazards and chemicals hazards.
Sincemany of the hazard risks may occur in the welding process field, the weldermust have knowledge about how to protect and work in safe conditions with theproper attributes of personal protective equipment for safety and health.
