The technical features of high-frequency welded H-sections include: (1) Fast welding speed, reaching 18–45 m/min; (2) Low thermal shock, making it easy to control deformation of the H-sections; (3) Capability to weld H-sections composed of different materials; (4) Ability to achieve production under slight tension, thereby reducing welding stress. Technical Specifications: (1) High dimensional accuracy of the cross-section; (2) Excellent cross-sectional properties; (3) Cross-sectional dimensions can be customized according to customer requirements.
This process involves locally heating a metal surface with high-frequency current and then welding it under external force. It requires no welding wire or flux and allows for continuous, high-volume production. Assemble two current-divider terminals (T-shaped, H59-1 brass) with five resistor plates (1.5 mm thick, 20 mm wide, 45 mm long, manganese-copper sheet); apply high-frequency heating; and solder using a special copper-phosphorus solder. Requirements: Brazing time ≤ 1 min; key challenges to address: positioning and brazing issues (previous brazing used oxy-acetylene welding). Main technical and economic indicators: No oxidation on the product surface after brazing; brazing quality superior to that of oxy-acetylene welding; terminals and resistor plates are firmly brazed together with no melting or deformation; the shunt’s resistive performance is guaranteed; production efficiency is doubled.
