Engineered for demanding automotive safety part fabrication, this automatic resistance projection welder delivers repeatable, high-strength joints on carbon steel (Q235, SPHC) and stainless steel sheet metal components. It is purpose-built for brake base plates, brackets, and mounting hardware, combining medium frequency inverter (MFDC) technology with a fully integrated automation cycle to support consistent throughput in high-volume production environments.
The machine performs both spot and projection welding with precise electrode force control, ensuring secure attachment of nuts, studs, and pre-formed projections without part deformation or weak weld nuggets. By pairing a closed-loop water cooling system with programmable PLC-based parameter storage, operators can switch between different workpieces quickly while maintaining weld quality standards required for critical safety components.
Supports both standard resistance spot welding and projection welding on a single platform, enabling optimal joint design for flat sheets, nuts, brackets, and other pre-formed features without additional tooling changes.
Servo or high-precision pneumatic force systems deliver stable, repeatable electrode pressure on every cycle, reducing cold welds, part deformation, and inconsistent nugget formation during long production runs.
Medium frequency direct current power provides concentrated, rapid energy transfer that minimizes heat spread, lowers spatter, reduces electrode wear, and extends consumable service life during continuous operation.
Integrated automatic part positioning, welding, and quality verification reduce manual handling and human error while improving overall production efficiency for brake component manufacturing lines.
A user-friendly color HMI allows digital adjustment of current, time, and pressure, with multiple stored parameter programs for rapid, error-free changeovers between different weld specifications.
Designed for seamless connection with industrial robots or rotary index tables, supporting unattended, continuous operation for manufacturers targeting high-volume output with minimal labor input.
| Industry | Typical Workpiece | Welding Mode |
|---|---|---|
| Automotive Brake Systems | Brake base plates, brackets, mounting hardware | Projection welding of nuts and studs |
| Sheet Metal Fabrication | Carbon steel panels, stainless steel sheets | Spot welding and projection welding |
| Industrial Component Assembly | Brackets, supports, pre-formed projections | Projection welding for rigid joints |
| Automotive Aftermarket Parts | Replacement brake components, hardware sets | Dual-mode spot and projection welding |
The projection welder uses medium frequency inverter (MFDC) technology to convert three-phase AC input into a controlled DC welding current. Pre-formed projections on the workpiece concentrate the electrical current and pressure at specific contact points, generating localized heat that fuses the materials into a strong metallurgical bond. A programmable PLC governs welding current, time, and electrode force, while a closed-loop water cooling system maintains stable temperatures in the transformer, arms, and electrodes for continuous operation.

The machine is designed for carbon steel sheets (e.g., Q235, SPHC) from 1mm to 6mm thick, as well as stainless steel sheet metal. It performs reliably on materials with light coatings or surface oxidation.
Yes, the system includes PLC-based controls and is compatible with industrial robots or rotary index tables, allowing for continuous, unattended operation in high-volume manufacturing environments.
The welder comes with a 1-year warranty covering free spare parts, field installation, commissioning, and operator training. After the warranty, video technical support and online assistance remain available.
Medium frequency direct current provides rapid, concentrated energy delivery with minimal heat spread, reducing spatter, lowering electrode wear, and ensuring consistent weld nugget formation on safety-critical parts.
