Abstract

The specimens of damaged tubes, ASTM A297 HK 40, are repaired by welding. Before repairing, solution annealing is used as a procedure for properties restitution. This paper explores the influence of used solution annealing procedure (1 050 şC / 2h) on mechanical and micro-structural properties. The emphasis is put on specific procedures at repair by welding.

Keywords
