PM Series Friction Stir Welder

MTI’s PM Series is the most compact and cost-effective Friction Stir Welding solution; purpose built for high volume production of smaller components. Engineered with precision 3-axis weld capability, the PM Series delivers true force and position control in a streamlined footprint, making it an ideal choice when manufacturers need full FSW capability without the scale of larger platforms. The PM Series offers robust process stability and repeatability for aluminum and other light metal welds commonly used across all industries including, and popular in automotive, electronics enclosures, and thermal management assemblies.  

To maximize productivity, PM machines can be equipped with dual part loading allowing operators to prepare the next set of parts while welding is in progress. This configuration significantly reduces idle time and supports continuous flow manufacturing. With its combination of accuracy, throughput, and small-scale efficiency, MTI’s PM series provides a powerful entry point into solid-state joining for manufacturers seeking reliable, repeatable performance in a compact production-class machine. 

All MTI FSW machines come standard with Stirtec’s STIRlytics® control platform, which combines closedloop force and position control with realtime process monitoring to ensure ISO 25239 compliant weld quality at high production speeds. Built on SIEMENS Sinumerik ONE CNC and S7 PLC hardware, STIRlytics® captures full weld traceability data, supports remote diagnostics and updates, and provides Industry 4.0 ready connectivity. This advanced digital control system minimizes downtime, strengthens process repeatability, and delivers the high level of consistency manufacturers expect from MTI’s FSW solutions. Together with Stirtec, MTI also provides customer-specific fixturing and pin tool design and manufacturing to drive superior process capability and weld quality for your application.
