Welding
is 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 of
metallic structures for instance bridges, pressure vessels, automobiles, ships,
and rails. In welding process, the welder must to protect their body for safety
and health from risk of hazardous which will be done with personal protective
equipment and other equipment. The welders should be overcome about hazardous
in 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 to
the welder with direct contact or no. Many factors of hazards may occur to the welder
in the weld area, the welder may have a knowledge about the potential hazards in
a welding process be solved with get through the work area, equipment,  material and consumables to be used. The physical
hazards are caused by Electricity, radiation, heat, flames, fire, explosion,
noise and magnetic field. 

 

One
of the potential hazard in a physical hazard is electricity. The electricity
hazard occur due to electric shock or electrocution. The electric shock in
welding process may bring out death or severe burns, if the welder contact with
electric energy, the welder will results shock and fall. So, the welder do not
works in wet area, broken insulation wire, carrying electric current cable
around the body, weld close to the welding cable, etc. Make sure that the
electrical installation is in good condition.

 

Then
the radiation from welding process have a reason to skin burning and peeling by
reason of the metal liquid on the weld metal is hot and contain ultraviolet when
the welder  not wear the right cloth.
Ascertain the combustible materials are kept away from welding area such as
paper, wood, plastic and others which will built a fire.

 

On
grinding process can results noise and sparks. Hearing loss can be caused by
hazardous noise levels, it is at or above 85 decibels that long or repeated
exposure to sounds can cause hearing loss. The safety equipment to reduce noise
is 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 by
welding fumes, fuel gases, inert gases, gas mixtures, and solvents. Chemical
hazards in the welding process are a type of welding risk that caused by
exposure to chemicals in the workplace. Exposure to chemicals in the field may
occur acute or long-term negative health effects.

 

Welding
process produce smoke that comprising particles of various types of oxides.
Fumes, such as carbon dioxide, ozone, and fumes containing heavy metals, can be
dangerous to the welders lacking proper ventilation and workplace procedure. When
welding with a fuel gas will produce carbon dioxide, but if a reduced flame
will produce carbon monoxide. Shielding gases such as argon, helium and carbon
dioxide, either alone or in mixtures with oxygen or hydrogen can also affect
health when not following proper work procedures such as working in a room with
good air circulation.

 

In
this research article, the potential hazards may experience as the welder in the
welding process are physical hazards and chemicals hazards.

 

Since
many of the hazard risks may occur in the welding process field, the welder
must have knowledge about how to protect and work in safe conditions with the
proper attributes of personal protective equipment for safety and health.
