What is Friction Stir Welding

FSW is a solid-state joining process that uses a pin tool to mechanically join two surfaces. This produces welds of high quality in materials such as aluminum and copper and is fast becoming the process of choice for manufacturing.


  • Joins Wide Variety of Materials
  • High Strength Joints/High Toughness
  • Localized Processing Capabilities
  • Low Heat Input/Low Distortion


  • Part Accessibility is Required
  • Process Forces Require Ample Fixturing
  • Localized Material Temper Disruption

Friction Stir Welding Capabilities

HFW has a dramatic impact across many industries, including aerospace, transportation, marine, hybrid electric vehicle and rail. We provide new solutions for old joining problems.


Superior mechanical characteristics

Friction stir welding produces welds with high weld strength and toughness, plus a fine grain structure that resists fatigue stress. Due to the low heat and small heat affected zone, there is minimal distortion of the joined parts, reducing costs associated with preparing the part for subsequent use.


Dual head capability for faster panel welding

Our machines are equipped with upper and lower weld heads for extrusions or panels that require a top and bottom welded assembly.


Virtually defect-free bonding

The bond made between two pieces of material is solely of the original material, giving it similar strength, bending, and fatigue characteristics of the parent metal.


Join dissimilar alloys

Friction stir welding can be used to join dissimilar alloys - even combinations not compatible with conventional welding methods.
