Introduction about the welding:

A welding flux is needed in welding. This flux is made of pine resin and resin mixture. The main ingredient is rosin (C20H30O2). At a high tempeature, rosin acid then cinveted to the new rosin acid. This results in production of toxic ingredients such as acetylsalicylic acid (HOC6H4COOH) and sobrerone. These toxic substances in to volatile gases. Flux which contains a lot of resin, also bring a phenyl(C6H5OH). and flux in the resin and activator also have chlorohydric acid (HCL) and other compounds. These gas inhalation cause headache, vomit halo, eye diseases and other diseases harmful to health.
