Industry Pain Points



In automotive, aerospace, and rail industries, friction stir welding requires durable tools to maintain weld quality. Conventional stir heads wear out quickly, causing frequent replacements, unstable weld seams, and higher production costs. Welding high-strength aluminum, copper, or dissimilar alloys amplifies these challenges.


Our Solution


We provide custom-engineered superalloy FSW tool heads designed for maximum durability and heat resistance. By optimizing both material and geometry, our tools deliver longer service life, consistent weld formation, and adaptability to diverse welding tasks. Clients can choose pin length, thread type, and shoulder design tailored to their production needs.


Key Advantages


  • Extended Tool Life – 30%-50% longer lifespan compared with standard FSW tools.

  • Custom Geometry – Pin, shoulder, and angle design tailored to specific welding conditions.

  • Stable Weld Quality – Optimized design ensures repeatable, defect-free joints.

  • Lower Operating Costs – Fewer replacements and reduced downtime.

  • Multi-Material Capability – Suitable for aluminum, magnesium, copper, and dissimilar alloys.


Applications


  • EV battery tray and motor housing welding

  • Aerospace aluminum-lithium and copper alloy structures

  • Rail transit aluminum extrusions

  • Heat sinks, cooling plates, and electronic housings


Technical Specifications 


  • Material: High-performance superalloy (multiple formulations available)
