AUTOMATIC BUILDING UP-WELDING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a new automatic building up-welding system effective for the automation of building up-welding, and easy to maintain stable quality. SOLUTION: Regarding surface modification by building up-welding, the automatic building up-welding system comprises: a filler metal feeding means; a flame torch preheating the surface part of a base material; a light source emitting light toward the surface part of the base material preheated with the flame torch; and a light receiver receiving light reflected at the surface part of the base material, and further comprises a control section detecting a surface smoothing phenomenon by the melting of the thin film at the surface of the base material as a light receiving intensity change and automatically controlling welding conditions.
