This automated projection resistance welder is purpose-engineered for joining carbon steel brake base plates and fasteners in automotive safety assemblies. By combining medium-frequency inverter (MFDC) or capacitor-discharge power with a servo-driven pressurization system and PLC-based digital control, it delivers repeatable nugget quality and consistent weld strength across Q235/SPHC steel sheets from 1 to 6 mm thickness.
The machine supports both spot and projection welding modes, making it an ideal solution for high-volume brake component manufacturing. With optional robot or rotary multi-station integration, it enables fully automated production lines where cycle time, weld consistency, and operator safety are critical. Built for durability, it minimizes spatter, reduces electrode wear, and maintains stable output even under continuous shift operation.
The weld head is driven by a servo motor or a high-accuracy pneumatic system, guaranteeing stable electrode force. This eliminates false welds and part deformation commonly seen with manual or low-cost machines, ensuring every joint meets automotive safety standards.
Switch freely between flat spot welding and nut/stud projection welding. This flexibility allows the same platform to handle different brake plate designs without additional capital investment, reducing your per-part cost.
Current, time, and pressure are precisely adjusted via PLC and touchscreen. Up to multiple welding recipes can be stored, enabling rapid changeover when you switch between workpiece variants — cutting downtime during batch production.
Integrated automatic positioning, welding, and optional detection functions reduce manual intervention. This boosts throughput and makes quality traceability easier for audit-ready automotive manufacturing.
Suitable for 1–6 mm carbon steel plates, including surfaces with light oil, coating, or slight corrosion. The MFDC or capacitor-discharge power supply delivers low-spatter, low-electrode-loss performance that extends consumable life and lowers maintenance.
A dedicated water cooling circuit keeps the welding transformer and electrodes at optimal temperature for non-stop work. The machine runs with reduced noise and fume, creating a cleaner, safer workshop environment.
| Industry | Typical Workpiece | Welding Mode |
|---|---|---|
| Automotive Brake Systems | Brake base plate (Q235/SPHC, 1–6 mm) | Projection welding of nuts/bolts |
| Heavy-Duty Equipment | Mounting brackets, structural plates | Spot welding with flat electrodes |
| Home Appliance & General Manufacturing | Sheet metal housings, support frames | Combination spot/projection welding |
| Automotive Aftermarket | Brake backing plates, wear indicators | Projection welding of small studs |
The machine uses an MFDC or capacitor-discharge power supply to generate a precise welding current. The upper electrode descends under servo/pneumatic force, clamping the workpiece between the electrode and the lower die. At the contact point, high current flows through the resistance of the material, generating localized heat that melts the metal and forms a solid weld nugget. For projection welding, raised features (nuts/studs) concentrate current and pressure at pre-defined points, enabling fast, repeatable joints with minimal thermal distortion. After the weld, the electrode retracts and the cycle repeats automatically under PLC control.

Yes, the machine supports welding of stainless steel nuts onto carbon steel base plates. The medium-frequency or capacitor-discharge power supply provides precise heat control, which is essential when joining dissimilar metals to prevent excessive intermetallic formation.
The standard models handle up to 6.0+6.0 mm combined carbon steel thickness. For heavier sections, we can configure a higher-force version or recommend a different power class.
Yes, with the optional robot or rotary multi-station feeding system, the welder can operate continuously. The PLC program automatically indexes parts, welds each point, and performs quality checks, reducing manual labor by up to 80%.
Thanks to the quick-release fixture system and stored welding recipes, a typical changeover takes less than 15 minutes. Simply swap the positioning component and recall the matching parameter set from the touchscreen.
