Abstract
The paper will present in detail the unconventional method of residual stress relaxation using explosion energy, which was used for the first time during the production of vessels - decanters, decomposers, and pipelines at the "Birač" alumina factory in Zvornik. The factory was built in the seventies of the last century. For the purposes of relaxation of residual stresses after welding, in E.O. Paton AN (Academy of Sciences) in cooperation with the Institute for Welding "Energoinvest" Sarajevo, a procedure for relaxation of residual stresses by explosion on welded joints was patented in 1976. The total length of the weld, which was treated with an explosion, was over 20.000 m.
Keywords
