PECULIARITIES OF THE STRUCTURE OF WELDED ALUMINUM ALLOY JOINTS

The paper presents results of studying the structure, distribution of chemical elements and microhardness values across the width of welded joints of AMg6 aluminum alloy sheets after pulsed arc welding and 01420 ones after laser welding. Results of studying the variation in the values of the contact elastic modulus through the welded joint of the AMg6 alloy and the strength of the 01420 alloy joint are discussed, as well as results of studying the granular structure of the alloys by the EBSD method.
