Background
Electric welding is a general term for electric arc welding, refers to a welding mode realized by melting metal parts to be connected through electric arc at high temperature by using a welding rod, and is the most widely applied welding method in industrial production. Theoretically, the process of metal combustion is the welding process, which is to melt the base material (welding part) and the filler (welding rod) to form a molten pool by using the high temperature generated by the current in the instant short circuit, and then the molten pool is cooled and transited into a welding line.
When welding, the welding rod is used as one electrode of the circuit, the weldment is the other electrode, an electric arc is formed between the two electrodes, and the metal is melted for welding. When welding, the temperature of the electric arc can reach 3000-.
In view of the harm of electric welding sparks, welders need to wear protective equipment such as protective head covers, flame-retardant protective clothing (conjoined or split), protective boots and the like during welding. At present, the fabrics of electric welding protective clothing are widely adopted in China, and mainly comprise oxhide, after-finishing flame-retardant cotton fabrics, Nomex IIIA fabrics and Kevlar fibers. However, the electric welding protective clothing made of cowhide has good protective effect, but is airtight, heavy to wear and poor in comfort; the electric welding spark impact resistance of the post-finished flame-retardant cotton fabric is poor, and the strength is low; the Nomex IIIA fabric and the Kevlar fiber are expensive. Therefore, a protective fabric which is comfortable to wear and has a good electric welding protection effect is in urgent need of development.
