Arc welding safety|shielded metal arc welding preparation & safety

Welding safety: During arc welding the welder is exposed to hazards such injury due to harmful rays (ultra violet and infra red rays) of the arc, burns due to excessive heat from the arc
and contact with hot jobs, electric shock, toxic fumes, flying hot spatters and slag
particles and objects falling on the feet.

SAFETY IN MANUAL METAL ARC WELDING

Welding Safety apparels

The following safety apparels and accessories are used to protect the welder and other
persons working near the welding area from the above mentioned hazards.

Safety apparels

a. Leather apron
b. Leather gloves
c. Leather cape with sleeves
d. Industrial safety shoes

Hand screen

a. Adjustable helmet
b. Portable fire proof canvas screens

Chipping/ grinding goggles

Respirator and exhaust ducting

Safety apparels

The leather apron, gloves, cape with sleeves and leg guard are used to protect the body, hands, arms, neck and chest of the welder from the heat radiation and hot spatters from the arc and also from the hot slag particles flying from the weld joint during chipping off the solidified slag.

All the above safety apparels should not be loose while wearing them and suitable size has
to be selected by the welder.

industrial safety boot

The industrial safety boot is used to avoid slipping, injury to the toes and ankle of the foot.

It also protects the welder from the electric shock as the sole of the shoe is specially
made of shock resistant material.

welding safety glasses

Welding hand screens and helmet

These are used to protect the eyes and face of a welder from arc radiation and sparks
during arc welding.

hand screen

A hand screen is designed to hold in hand

helmet screen

A helmet screen is designed to wear on the head.

It provides better protection and allows the welder to use his both hands freely.

Screens are made of non-reflective, nonflammable, insulated, dull coloured, light material
with coloured (filter) glasses fitted with plain glasses on both sides to see the arc and molten pool while welding.

Clear glasses are fitted on each side of the coloured glass to protect it from weld
spatters.

Coloured (filter) glasses are made in various shades depending on the welding current
ranges used as given below:

Recommendation of filter glasses for manual metal arc welding Shade No. of coloured glass

Range of welding current in amperes

Portable fire proof canvas screens are used to protect the persons who work near the welding area from arc flashes.

Plain goggles are used to protect the eyes while chipping the slag or grinding the job.

It is made of Bakelite frame fitted with clear glasses and an elastic band to hold it securely on the operators head.

It is designed for comfortable fit, proper ventilation and full protection from all sides.
