Direct current TIG welding of metal matrix composites

The introduction of new generation materials with improved mechanical and operational properties increases the reliability of water transport means, thus the safety of shipping, and reduces operating costs. This group includes cast metal composite materials. However, there is still no precise and quick description of the method of combining these materials, which significantly hampers their use. Therefore, work is ongoing on the selection of good quality methods of their bonding. In this work, an attempt was made to join cast AlSi/SiC composites by TIG welding using direct current.
