In the automated production of relays and magnetoelectric components, resistance welding has become one of the core joining processes due to its advantages of high efficiency and strong weld spot consistency. It is widely used in the welding forming and assembly of key components. Its application scenarios focus on relays (such as electromagnetic relays, solid-state relays) and magnetoelectric devices (such as electromagnets, inductance coils, magnetic core assemblies), etc.
Specific Applications of Resistance Welding in Automated Relay Production
• Spot welding / projection welding of coil leads and pins
• Seam welding / butt welding of iron cores and yokes
• Projection welding / spot welding of contacts and brackets
• Spot welding of movable reeds and armatures
• Seal welding of housings and bases
• Welding of coil leads and terminals: low loss, high adaptability
• Welding of magnetic cores and yokes
• Welding of pins and bases: integrated structural fixation and electrical conductivity
For the above welding processes, the following electrodes can be selected based on different base metals:1: Inserted electrodes 2. Tungsten-molybdenum electrodes 3. Copper alloy electrodes
