Spot welders are mainly classified according to eight dimensions, including purpose, number of welds, conduction method, pressure mechanism transmission method, power supply type, etc., and can be specifically divided into universal type (general/special), single point/double point/multi-point, single-side/double-side conduction method, pneumatic/hydraulic transmission and other types.
Classification dimensions and specific types
The classification system of spot welders includes multiple independent dimensions, each of which corresponds to different industrial needs:
Classification of use:
Universal type (general type, suitable for a variety of scenarios)
Special type (customized for specific workpieces)
Number of welds:
Single point type (single weld operation)
Double point type (double weld simultaneous processing)
Multi-point type (batch welding assembly line application)
Conduction method:
Single-side conduction (single-side electrode energized)
Double-side conduction (double-side electrodes work together)
Pressure mechanism transmission method:
Foot-operated (manual operation)
Motor-cam type (mechanical transmission)
Pneumatic (pneumatic drive)
Hydraulic (hydraulic power)
Compound (gas-liquid hybrid transmission)
Operation characteristics:
Non-automatic (more manual intervention)
Automatic (integrated intelligent control system)
Installation method:
Fixed (fixed installation in the workshop)
Mobile (portable and portable)
Suspended (used in conjunction with a crane)
Power supply type:
Industrial frequency spot welder (50Hz AC power supply)
Pulse spot welder (capacitor energy storage technology)
Variable frequency spot welder (medium frequency/high frequency energy-saving model)
Electrode movement direction:
Vertical stroke (linear motion mode)
Circular stroke (arc trajectory motion)
