Mobile WebSiteAutomotive wire harness welding currently has two main types of crimping and ultrasonic welding: crimping is the use of terminals to press together multiple strands of wire to form joints; ultrasonic welding uses the physical effects of ultrasonic vibration to join the ends. Ultrasonic application in automotive wire harness welding production began to be popular in Europe and America, mainly due to the development of foreign ultrasonic metal welding technology. Comparison of two welding techniques:
(1) Crimp
Advantages: fast production speed; simple equipment.
Disadvantages: There is a risk of rebound in metal stamping; there is a risk of oxidation and rust under severe conditions, and all risks can lead to poor contact.
(2) Ultrasonic welding
Advantages: Superior electrical connection characteristics (basic zero resistance); insensitive to the risk of oxidation and rust under severe conditions.
Disadvantages: expensive equipment; consumables are also more expensive.
