D series Laboratory Vacuum Diffusion Welding Furnace

Diffusion welding can weld almost all metals or non-metals without reducing the performance of the welded material, as the substrate does not overheat or melt. It is particularly suitable for fusion welding and other materials that are difficult to weld, such as active metals, heat-resistant alloys, ceramics, and composite materials. For the same type of material with poor plasticity or high melting point, as well as dissimilar materials that are immiscible or produce brittle intermetallic compounds during fusion welding, diffusion welding is a more suitable welding method. The diffusion welded joint has good quality, and its microstructure and properties are similar or identical to the base metal. 

There are no fusion welding defects, overheating structure, and heat affected zone in the weld seam. Welding parameters are easy to precisely control, and joint quality and performance are stable during mass production. Welding parts have high accuracy and small deformation. Due to the low pressure applied during welding, the workpiece is mostly heated as a whole and cooled with the furnace, resulting in minimal overall plastic deformation of the welded part. The welded work piece is generally not subjected to mechanical processing.

It is possible to weld large section workpieces with relatively low welding pressure, so the tonnage of equipment required for large section welding is not high, making it easy to achieve. It can weld workpieces with complex structures, difficult to access joints, and significant thickness differences, and can simultaneously weld many joints in the assembled parts.  Fast cooling speed: optional with a fast cooling system under a gas pressure of 2 bar to 10 bar, ensuring fast cooling and efficient operation of the workpiece after hot pressing;
