Welding, also known as the melt, Jae Yong is a heating, high temperature or pressure bonding of hot metal or other plastic materials manufacturing process and technology.
Production and harm of welding dust In the welding process, will produce a lot of smoke and dust. It includes smoke and dust, particles of less than 0.1 microns in diameter for the smoke, the diameter of 0.1 Mu to 1 m between the particles called dust. Welding arc temperature as high as more than 3000 DEG C, the temperature of the arc center even higher than 60 DEG C, metal elements in operating under high temperature to vaporize rapidly after a run of low temperature air and rapid condensation, thus forming a metal oxide, spread to the surrounding, and other air material combination into a mixed dust.
Welder, long-term exposure to metal fumes, if inappropriate protection and breathed in too much dust will cause headache, nausea, tracheitis, pneumonia and even the formation of welder pneumoconiosis, some radioactive dust and carcinogenic, toxic dust inhalation can cause systemic symptoms of poisoning.
Hebei Shengtian group provide a series of products of good quality steel pipe fittings for you.
