Abstract

It was determined that the maximum level of strength is achieved after full heat treatment (quenching and artificial ageing) after welding. Heat treatment of welded joints made by friction stir welding leads to structural heterogeneity alignment and removal of weakening of the heat affected zone. After-welding modes of heat treatment do not practically influence the protective properties of non-metallic inorganic coatings.
