Тechnological aspects of surface preparation of wrought aluminum alloys to arc welding
The researches results of influence of surface preparation method of welded wrought aluminum alloys to arc welding are presented. It is shown that the optimal method of surface preparation of aluminum alloys under arc welding is thermal vacuum processing and high-speed milling. It is founded that the structure and the thickness of the oxide films are defined by the chemical composition of the alloy and method of preparation.
