Overview

Advanced Shaft Welding for Complex Assemblies & Multi-Material Solutions

AmTech International manufactures welded shafts with diameters from 25mm to 200mm and lengths from 25mm to 1016mm, supporting a wide variety of industrial and OEM requirements.

Friction Welding for Cost-Effective Performance

Rising raw material costs and the demand for high-performance components have made efficient manufacturing methods essential for OEM customers, especially in pump shaft production. Friction welding is a proven solution that helps reduce production costs while maintaining exceptional product integrity.

In friction welding, multiple shaft sections are joined by pressing them together while one part rotates at high speed. The resulting friction generates heat, causing the materials to reach a plastic state and fuse into a permanent, high-strength bond. This process is ideal for joining dissimilar materials—such as stainless steel to carbon steel—optimizing both cost and performance. Welded shafts produced by friction welding maintain mechanical properties comparable to forged shafts, with excellent fatigue resistance and tensile strength.

Advanced Welding Techniques

  • Laser Welding: Enables precise, high-speed joining with minimal heat distortion, making it suitable for delicate or complex shaft assemblies.
  • Robotic Welding: Provides consistent weld quality and repeatability, especially valuable for high-volume production runs.
