Advantages and disadvantages of diffusion welding machine [DW02]
Dec 20,2023
Advantages
Compared with other welding methods, diffusion welding machine has the following advantages:
- Suitable for homogeneous or dissimilar materials that are difficult to be welded by fusion welding and other methods.
Because the matrix metal does not overheat or melt during diffusion welding, almost all metals or nonmetals can be welded without reducing the properties of the materials. Diffusion welding is especially suitable for materials that are difficult to be welded by fusion welding and other methods, for example, active metals, heat-resistant alloys, ceramics and composites. As for homogeneous materials with poor plasticity or high melting point, and for dissimilar materials that do not fuse or produce brittle inter-metallic compounds during fusion welding, diffusion welding is a suitable welding method.
- Good quality of diffusion welded joint
The microstructure and properties of the diffusion welded joint are similar to or the same as the base metal. There is no weld defect, superheated structure or heat affected zone in the weld connection. The welding parameters are easy to reach accurate control, and the joint quality and performance are stable in batch production.
- High welding accuracy, small deformation.
Because the welding pressure is small, the workpiece welding area is heated and cooled overall as a whole. So the overall plastic deformation of the welding is very small. The workpieces after welding generally only need a slight mechanical processing.
- Able to weld large section workpiece.
Because the welding pressure is not big, large section welding equipment tonnage is not high, easy to achieve.
- Able to weld complex structure workpiece or parts with difficult access to joints or large thickness differences. Also able to weld many joints in the assembly at the same time.
Disadvantages
The main disadvantages of diffusion welding machine are as follows,
Strict requirements on the quality of welding surface preparation and assembly, especially on the joint surface.
Welding heat cycle time is long, long may be several minutes for big welding area workpieces. Low productivity. Presently there has been a huge improvement.
The one-time investment of the welding equipment is large, and the size of the welding workpiece is limited by the equipment. It is impossible to carry out continuous batch production.
The power of the diffusion welder is generally large and the requirement for the power grid is high.
Now the diffusion welding machine is mainly custom provided, based on customer demand or products to be processed. To a large extent, the welder can offset the shortcomings of its own process.
