Experimental Section


Depending on the shape and size of the piece, heat treatment for residual stress relief can be carried out by heating the entire piece, or parts of it, in a furnace; or transforming it in a combustion chamber by installing a temporary burner into it, or treating the welds one by one by means of electric resistances. Heating by exothermic kits, which enjoyed some popularity in the sixties and seventies, was abandoned because it did not produce the expected results.
