Potential Safety Hazards and Key Precautions in Welding Operations!
As a critical industrial process, welding is widely used in modern industrial production and daily life. However, if operators neglect safety precautions or violate safety operating procedures during welding, they may create fire hazards.
Welding is classified as hot work. Violations such as performing hot work during business hours, operating without a hot work permit, working without proper certification, handling flammable or explosive materials during operations, and failing to provide appropriate firefighting equipment are all considered non-compliant practices. These significantly increase the risk of fire or explosion.
During welding operations, molten metal sparks can scatter in all directions. Careless operation can easily lead to fires. Electric welding is an open-flame operation, with arc temperatures typically reaching 3,600–6,000°C, posing risks of high temperatures, high pressure, and flammability or explosiveness.
The extensive high-temperature sparks and slag generated during welding can smolder and spread upon contact with combustibles such as wood, leading to fires. Contact with explosive gases may trigger explosions.
The power cables connected to welding machines are frequently dragged during operation, which can cause insulation aging and damage, resulting in short circuits that may ignite nearby combustible materials.
Given these safety hazards, how can we prevent fires caused by electric welding?
