Final answer:
Welding clothes should be made of flame-resistant materials like Nomex or leather that protect against the intense thermal energy produced by the welding arc. The clothing should fit properly and be kept free from flammable substances.
Step-by-step explanation:
Material of Clothes for Welding
The material that clothes worn during welding should be made of is a crucial consideration for safety. Welders are exposed to extreme heat, sparks, and ultraviolet radiation, which can pose significant risks. Therefore, welding attire should be constructed from materials that are flame-resistant and can provide protection against these hazards. Materials such as Nomex and leather are commonly used because they are resistant to melting and provide a good level of thermal insulation. Nomex, in particular, is a flame-resistant, high-temperature fiber that doesn't melt or drip and retains its integrity under intense heat.
As highlighted in the reference information, welders utilize heavy-duty gloves and helmets in addition to their protective clothing, to shield themselves from the electric arc. This arc generates enough thermal energy to melt metal, emit hazardous sparks, and produce high-energy electromagnetic radiation that can severely damage one's skin and eyes if not adequately protected. Military pilots, aircrew, and racing car drivers also use Nomex in their attire to ensure protection against the possibility of fires. Similarly, welding clothing should provide enough insulation to protect the welder from high temperatures and potential burns.
It is worth noting that clothing for welders should also fit properly to avoid any loose ends catching sparks, and it should be kept free of oils, grease, or any flammable substances that could ignite under high temperatures. Kevlar thread might also be used to reinforce seams in welding clothing for added durability and fire resistance.
