High-handed Pipe in Power Plant F11 Steel Joins by Welding the Technology and Analyse

Through the situation of slight crack of brazing seam is verified to high-handed pipe.Decision adopts and join by welding near dig the method built up and carry on renovate.For this to mother's material metal F11 the steel joins by welding the nature and weld and built up the characteristic of technology make the detailed analysis.It is reasonable to carry join by welding and standard of heat treatment,Dig with the guarantee built up and join by welding the effect renovate.And point at the interval of root more wider practical situation.Seek for F11 the steel thick wall wide interval fining charge of built up and weld the method.Adopt the double-deck TIG weld and beat the bottom join by welding.It proved to join by welding the center in the high alloy steel high alloy steel.In guarantee air of argon to protect the measure on the tight foundation.Adopt and weld the double –deck the double-deck beat the method the bottom TIG join by welding the double desk and beat the method the bottom welded.Better guarantee joins by welding the quality.cut down the production to join by welding defect.It got the better effect.
