Resistance welding process parameters have a direct impact on welding quality. Reasonable selection and adjustment of these parameters can ensure the stability and consistency of welding quality. The following are some common resistance welding process parameters and their impact on welding quality:
1. Welding current (Welding Current):
Impact: The welding current directly affects the heat input during welding. Too high or too low welding current will affect the welding quality.
Impact of high current: Too high current may cause excessive melting, deformation of welding points or overflow of welding materials, thereby affecting welding quality.
Impact of low current: Too low current may cause insufficient melting of welding points, weak welding, and affect welding strength.
2. Welding time (Welding Time):
Impact: The welding time affects the heat input and solidification time of the welding point, and has an important impact on the formation and stability of the welding point.
Impact of too long welding time: Too long welding time may cause excessive melting, too large heat-affected zone, and even deformation of the welding point.
Impact of too short welding time: Too short welding time may cause insufficient melting of welding points and insufficient welding strength, affecting welding quality.
3. Welding Pressure:
Impact: Welding pressure affects the fit of the welding contact surface and the density of the welding point.
Impact of excessive pressure: Excessive pressure may cause deformation of the welding contact surface, affecting the welding quality and surface flatness.
Impact of too little pressure: Too little pressure may lead to insufficient welding contact surface, affecting the firmness and strength of the welding point.
4. Welding environment temperature and humidity:
Impact: The temperature and humidity of the welding environment have a direct impact on heat transfer and material properties during welding.
Excessive temperature: High temperature environment may cause local overheating of the welding point, affecting the welding quality.
Excessive humidity: Excessive humidity may cause oxidation of welding materials, affecting the welding quality and strength.
5. Welding electrode material and shape:
Impact: The material and shape of the electrode directly affect the formation and stability of the welding point.
Appropriate material and shape: Appropriate electrode material and shape can provide good welding contact and thermal conductivity, which is conducive to improving welding quality.
6. Welding surface treatment and cleanliness:
Influence: The treatment and cleanliness of the welding surface directly affect the welding contact and thermal conductivity.
Clean surface: A clean welding surface is conducive to the formation of welding points and the improvement of welding quality.
In summary, the reasonable selection and control of welding current, time, pressure and other parameters, as well as the attention to factors such as temperature and humidity of the welding environment, can effectively ensure the stability and consistency of welding quality.
