How does electric welding cause fire? (Technical aspects)

✔Flying sparks, molten metal and slag particles ignite flammable materials and combustible gases near the welding point and cause fire.

✔The soft wire of the electric welder is dragged for a long time, causing insulation damage and short circuit and fire, or the electric welding return line is randomly placed, causing fire.

✔The insulation of the power line of the electric welder itself is damaged and short circuits and heat up, causing fire.

How does electric welding cause fire? (Management aspects)

✔The quality of electric welding workers is uneven, and they lack the necessary safety awareness and skills, which increases the risk of fire. Especially at the site of urban construction projects, there are many flammable and combustible materials. When the fire occurs, it burns violently and spreads rapidly, accompanied by a large amount of toxic gases, which can easily cause poisoning or suffocation and death, causing adverse effects.

✔Failure to declare and file in accordance with the law, illegal subcontracting, working without a license, and barbaric operations are common. This exposes many problems such as imperfect laws and regulations, subcontracting of projects at all levels, and weak supervision of special industries. For example, some construction units take over the demolition project and leave the site safety alone; construction contractors fail to fulfill their safety responsibilities, seriously fail to take safety measures, fail to manage site safety, and arbitrarily subcontract and sub-contract projects; personnel who start fires at construction sites do not hold certificates, and fail to go through approval procedures before starting fire operations.

✔The threshold is low and the equipment is cheap. Some people buy a set of welding equipment on their own and engage in welding operations. Although relevant departments have strict requirements for welders to hold certificates, some construction units do not care whether welders have certificates in order to save costs or after layers of subcontracting. Due to the fast turnover of welders and the lack of fixed units, it is difficult for regulatory authorities to implement qualification permits and effective management.
