Possibilities of Porosity Repairs after Aluminium Alloys Welding

Abstract

This article describes problems of porosity which are caused after welding of aluminium alloys. The main part of this article is dedicated of methods of correction of porosities. The best correction is by welding or by cementation. Described parts are used for welded aluminous vehicle parts in a cooperative company. Thanks to porosity are effected not only ductility and strength of welded structures but also weld quality thereby fall also resulting in surface treatment.This article describes problems of porosity which are caused after welding of aluminium alloys.
