COMPARATIVE MECHANICAL AND METALLOGRAPHIC INVESTIGATIONS OF WELDED COMPOUNDS WITH HIGH-STRENGTH TITANIUM ALLOYS OBTAINED BY METHOD OF TIG AND EBW
The paper presents the results of mechanical and metallographic studies of the welded joints structure of the high-strength titanium alloys 20-30 mm width. In the paper is shown that with TIG and EBW welding of high-strength titanium alloys, there is a tendency to form defects in the weld metal. The...

| Summary: | The paper presents the results of mechanical and metallographic studies of the welded joints structure of the high-strength titanium alloys 20-30 mm width. In the paper is shown that with TIG and EBW welding of high-strength titanium alloys, there is a tendency to form defects in the weld metal. The results of metal chemical composition are shown in the paper as well thermal influence, micro- and macrostructure of welded joints and the measurement of hardness are presented. Recommendations are developed, which in a great degree exclude the appearance of defects in welded joints and increase their performance characteristics. |
