40-200KVA 25mm CE RoHS Resistance Butt Welder For Copper Rod Steel Wire Ring Welding
This resistance butt welding machine is a professional system engineered for the precision butt joining of metal rings, copper rods, and various steel materials. Its core technology is based on resistance welding principles. By applying precisely controlled pressure and a high-density current to the facing ends of two workpieces, the contact surfaces are instantly melted by resistance heat and forge-welded into a solid metallurgical bond under upset force. The equipment excels at creating reliable joints between highly conductive materials (like copper) and structural steels. It is widely used for butt welding metal bars, pipes, and profiles, serving as a dependable choice for achieving high-efficiency, high-strength, and highly consistent butt welding operations in the electrical, hardware, and machinery manufacturing industriesTechnical Parameters

-
High-Stability Pneumatic/Hydraulic System: Utilizes a high-performance pneumatic or hydraulic pressurization system to deliver sustained, stable, and high clamping force. This fundamentally ensures the workpiece remains completely free from slippage or misalignment throughout the entire upset welding process, resulting in exceptionally stable and reliable welding performance.
-
High-Precision Wear-Resistant Guidance: Features a hardened, precision dual-guide rail system with strong wear resistance, enabling smooth and stable movement. This provides a solid mechanical foundation for achieving exceptional alignment and consistency of the workpiece butting faces.
-
Efficient & Reliable Upset Actuation: Incorporates an optimally designed hybrid-drive upset mechanism that operates smoothly and can deliver an instantaneous, massive, and precisely controllable upset force. This ensures thorough recrystallization of the molten metal under high pressure, significantly enhancing joint density and overall mechanical properties.
-
Dedicated High-Performance Forming Electrodes: The die electrodes are precision-manufactured from high-strength Chromium Zirconium Copper alloy. This material offers outstanding electrical conductivity, high-temperature strength, and wear resistance, specifically optimized to withstand high-current welding and continuous production, ensuring a stable welding process and long electrode service life
