Stud welding is a precision welding process that melts the stud end and the workpiece surface via arc heating, then completes metallurgical bonding through instant pressurization. Its core features focus on three dimensions: high speed and efficiency, single-sided operation, and high strength & reliability. The welding cycle can be controlled within 0.5 seconds

Spot welding (resistance welding) is a foundational process in automotive manufacturing. By applying pressure through electrodes and passing high current through workpieces, localized melting occurs via contact resistance heat to form a weld nugget. Its core advantages include high efficiency, low cost, ease of automation, and a small heat-affected zone

Projection welding is a precision branch of resistance welding. By pre-forming protrusions on the workpiece surface, the welding current is concentrated at these projections, which are melted by resistance heat and formed under compression. Its core features are precise heat generation, stable quality, minimal workpiece damage

SPR (Self-Piercing Riveting) is an advanced cold-forming solid-state joining technology. Its core principle is: a special rivet directly pierces the upper sheet metal under pressure and plastically expands in the lower sheet metal to form a mechanical interlock structure, completing the connection in one step. The whole process features

FDS (Flow Drill Screwdriving) is an innovative thermo-mechanical joining process. Its core principle is: the screw rotates at high speed to generate frictional heat with the workpiece,

Adhesive application is a core process in new energy manufacturing that integrates both functional and structural purposes. By applying adhesives, sealants, thermal gels, and other compounds along predefined paths on workpieces, it delivers five core values: sealing and waterproofing, bonding and fixing, shock absorption and cushioning
