The go-to tools for Hard MMCs (Metal Matrix Composites), Aluminium, and even Copper or Titanium alloys.
High-grade tungsten carbide grades minimize tool debris shedding into the weld nugget, critical for aerospace and EV battery tray applications.
Friction Stir Welding (FSW) is a revolutionary solid-state joining process that creates high-strength, defect-free bonds without melting the base materials. Unlike traditional fusion welding, which relies on high heat and filler metals, FSW uses a non-consumable rotating tool to generate frictional heat. As the tool traverses the joint, it plasticizes the metal, “stirring” the two workpieces together into a single, seamless forged bond. This low-heat approach virtually eliminates common welding defects like porosity, solidification cracking, and extreme distortion, making it the gold standard for high-performance applications in aerospace, automotive, and marine industries.

In high-cycle production and the welding of hard alloys, the tool is the most vulnerable point in the process. Tungsten Carbide (WC) pins offer a massive performance leap over standard tool steels by maintaining exceptional hardness and structural integrity at temperatures exceeding 1000°C. While traditional steel tools may soften or deform under intense friction, our Tungsten Carbide grades provide the extreme wear resistance needed to maintain precise pin geometry. This results in a more stable “stir zone,” consistent mechanical properties in the weld nugget, and a significantly lower cost-per-meter due to extended tool life and reduced machine downtime.

Shorter overall length by regrinding
The right surface treatment turns a consumable tool into an industrial asset by minimizing stress, stopping material sticking, and improving tool life.
Delicate mirror polishing with elastic cored abrasive media
Chrome-nitride or Diamond like carbon
Against high wear or abrasive aluminium
We manufacture high-performance tungsten carbide FSW tooling that has precision performance where standard tool steels fail.
In high-cycle production and high-melting-point alloy welding, tool degradation is the enemy of consistency. Our proprietary Tungsten Carbide pins are engineered for maximum thermal stability and wear resistance, ensuring that your 1,000th meter of weld is as structurally sound as your first.

The FSW pressing holder is a customizable spot welding device for friction stir welding of large or thin sheets.
Holder applies light pressure on sheet surface
Eliminates need and cost for large scale jigs
No need for temporal fastening/fixing
How our FSW pressing holder works:
Holder touches top layer and applies light pressure.
FSW spindle rotation starts to make spot welding.
As material layer is fixed now, it is ready for further processing (line welding, milling, next material layer).
Clampless additive manufacturing for large sheet metal fabrication
Our FSW pressing holder allows additive manufacturing of sheet format materials to form coolant channels layer by layer.
First, a new material layer is stacked, temporarily spot welded to fix its position.
Then friction stir line welding creates waterproof connection, finished by surface milling.
Prototype friction stir welding pins can be further evaluated at FUJI SEIKO JAPAN for observation of welding behavior in a machining center:
With the analysis of tool groove stresses from lateral load data, we can optimize groove geometry and welding conditions.
Equipment
We have two types of FSW testing equipment and a variety of measuring instruments. We also provide test cut services.
