Structural characteristics and mechanical properties of 2219 aluminum alloy DC A-TIG welding joints

Based on the direct-current active TIG welding（DC A-TIG welding）process of 2219 aluminum alloy, combined with engineering practice, three main parameters of welding current, welding speed, and rotation speed were selected for process testing. The significant changes in microstr...
