Technical Advantages
When welding with a vacuum electron beam welding machine, the energy density is high (about 108 watts/cm2), resulting in a high depth-to-width ratio of the weld seam and a small heat-affected zone. There is no need for filler metal, and it offers a high welding speed for high-quality industrial products, allowing for the one-time penetration of thick materials. Welding under vacuum conditions effectively prevents oxidation of the workpiece during the welding process. It provides high reliability and repeatability, with a wide range of adjustable process parameters and strong adaptability for welding a variety of materials.
