When should arc welding and cutting operations be shielded?

Arc welding and cutting operations should always be shielded to protect against various hazards associated with these processes. The shielding serves to safeguard not only the welder but also those in proximity from harmful effects such as intense ultraviolet (UV) and infrared (IR) radiation, sparks, spatter, and heat. The shields help to prevent possible injuries, including burns and eye damage, that can result from exposure to bright welding arcs.

In addition, shielding can prevent the ignition of flammable materials and can help contain equipment malfunctions. The use of protective barriers or enclosures is a required practice in construction environments to ensure that workers who are not directly involved in welding operations are adequately protected. Overall, the consistent application of shielding reflects compliance with safe work practices as outlined in OSHA standards.
