Brazing and Welding Technology

Vacuum Brazing Process and Heat Treatment

Using a vacuum furnace to provide a good reducing atmosphere, with a suitable furnace temperature curve and solder, the workpiece is heated to a high temperature for self-joining, and at the same time achieves the effect of higher strength than the base material, stress relief, and restores the metal color of the surface of the workpiece.
The effective hot zone of the vacuum furnace is L2000mm*W1000mm*H914mm.
KAORI has rich experience in fixture design and mold development, a complete supply chain, and a complete quality management system.

It is used for the joining of complex welding surfaces, such as: turbine blades, finned heat exchangers, etc. The appearance after welding can restore the metal color, the deformation is small, and the welding strength can be improved.
The effective hot zone of the vacuum furnace with large space realizes the possibility of large-sized workpieces and mass production.
KAORI's team and supply chain can provide strong technical support.

Overcome the welding that general argon welding cannot perform. Example: surface-to-surface bonding, subtle and complex welding requirements.
The ability to complete bonding, annealing, and oxide reduction at the same time is widely used in automobiles, semiconductor equipment, and aerospace industries.
It can be applied to various joint surfaces, improving the freedom of customer weld bead design, and the workpiece has excellent air tightness, electrical conductivity, and thermal conductivity after hard welding.
Provide a complete product development plan from material preparation, design, proofing, to mass production.
