READ MOREWhat welding process is used for the contacts of the CXCH series-circular electrical connector? How to ensure the reliability and stability of welding?
1. Contact welding process of CXCH series circular electrical connectors
The contact welding process of the CXCH series circular electrical connectors is the key link to ensure its high performance. The contacts of this series of electrical connectors adopt advanced precision welding technology, which specifically includes the following steps:
Material selection and pretreatment:
Contact material: In order to withstand high-load work in harsh environments, the contacts of the CXCH series electrical connectors usually use highly conductive and corrosion-resistant alloy materials, such as copper alloys or precious metal alloys.
Pretreatment: Before welding, the surface of the contact must be strictly cleaned and deoxidized to remove impurities such as oil and oxides to ensure the purity and bonding strength of the welding surface.
Precision welding technology:
Welding method: HENGLIAN uses precision welding technologies such as micro-beam plasma welding or laser welding, which can achieve high-precision local heating and reduce the heat-affected zone, thereby maintaining the original performance of the contact material.
Welding parameter control: During the welding process, the welding current, voltage, welding speed and other parameters are precisely controlled to ensure the consistency and stability of the welding quality.
Post-welding inspection and processing:
Non-destructive testing: After welding is completed, the welding parts are inspected for internal defects by means of X-ray detection, ultrasonic detection and other means to ensure the welding quality.
Appearance inspection: The welding parts are inspected to ensure that the weld is flat, free of cracks, pores and other defects.
Post-processing: The welding parts are cleaned and passivated as necessary to improve their corrosion resistance.
