Welding principle of plastic deformation for seamless steel pipe

Seamless heat treatment after welding is a new technology to eliminate residual stress, this technology can improve the metal's resistance to stress corrosion, and heat treatment temperature is higher, the elimination of residual stress, the better, of course, the heat treatment or can effectively improve the corrosion resistance of welded steel pipe. Try to make the weld metal biphasic organization, content to make ferrite controlled more than three percent, five percent, while the need yo selection of quality basic coated electrodes, so that you can limit the welding seam metal three kinds of S, P, C and other content.
