METHOD FOR MECHANICAL CHARACTERIZATION OF METAL MATERIAL

PROBLEM TO BE SOLVED: To ensure that a built-up weld metal is suitable for repair without unfavorably weakening the mechanical characterization of a repaired area. SOLUTION: The method characterizes a metal material mechanically to a material to constitute a portion to be repaired, and justifies a d...

Zusammenfassung:	PROBLEM TO BE SOLVED: To ensure that a built-up weld metal is suitable for repair without unfavorably weakening the mechanical characterization of a repaired area. SOLUTION: The method characterizes a metal material mechanically to a material to constitute a portion to be repaired, and justifies a device for repairing the portion by the build-up welding with the metal material. According to the method, a recess is machined in a metal bar, the recess is subjected to the build-up welding 54 by the repairing device. A test piece 56 is cut out of the metal bar so that the test piece has a center area consisting of only build-up weld metal, and the test piece is subjected to the axial direction vibration fatigue test.
