1. Strong thermal conductivity, Fuse Copper Contact Knife Cap has high thermal conductivity, and requires a high-power heat source; preheating the weldment can be used for welding End Cap and Contact.

2. The fluidity is large, and the molten copper liquid has good fluidity, and can only be welded in the flat welding position. If one-side butt welding is to be performed in a spatial position, a backing plate must be added to ensure penetration and obtain good forming.

3. The thermal expansion and cold contraction are large, and the coefficient of linear expansion of Copper End Cap and Contact Welding Components is large, and the phenomenon of thermal expansion and cold contraction during the welding process is particularly obvious, so the deformation after welding is large.

Resistance brazing of Fuse Contact Caps features:

1. Fast heating speed

Direct heating through the current, second-level speed.

2. Good welding effect

The brazed joint of Fuse Cap and Contact is smooth, beautiful and firm.

3. Small deformation

The heating concentration is uniform, so the heat affected zone is small, and the deformation and stress are also small. It is easy to ensure the dimensional accuracy of the workpiece End Cap Contact, and it is not necessary to consider the correction or heat treatment process after welding.

4. High thermal efficiency

Using the internal resistance heat source of the workpiece itself Tin Plated Copper End Caps, the heat energy loss is relatively small, the thermal efficiency is relatively high, and the energy saving is saved.
