• The Friction Welding Advantage
  was needed, resulting in extensive downtime. By friction welding the more durable stainless steel ends onto the metal tube shaft, the life expectancy of the part was extended by eight times. With replacement costs lowered and downtime reduced, higher production volume and increased capacity were...
• Welding with light
  thermoplastics often weigh and cost less than equivalent metal castings and stampings. Typically, these assemblies are welded together by heat from friction, hot plates, or radiant heaters. Although these methods produce welds of. Welding with light | Machine Design. Skip to Content. Home. Subscribe...

  width than the HAZ of a conventional weld that incorporates. a filler material. HAZ mechanical properties are similar to the base metal, but, depending upon the temperature. achieved during welding, the cooling rate and the post-weld thermal treatment, all three can change the weld. properties...
• Causing a stir in welding
  the material as it travels from the front of the rotating pin to the back. Here it consolidates and cools, forming a solid-state weld. Unlike fusion welding, there is no actual melting and the weld has the same fine-grained condition as the parent metal. Most friction stir welding systems use...
• Metal Coatings
  , and for cladding in reaction vessels. Electroless nickel plating, in contrast to conventional electroplating, operates chemically instead of using an electric current to deposit metal. The electroless process deposits a uniform coating regardless of substrate shape, overcoming a major drawback...
• The Application of OIM to Friction Stir Processing of Cast NiAl Bronze Materials (.pdf)
  Orientation imaging microscopy (OIM) has been used to investigate deformation and recrystallization during friction stir processing (FSP) of cast NiAl bronze materials. FSP is a novel adaptation of friction stir welding (FSW), a solid state joining technology originally developed at The Welding...
• Improved Fatigue Performance of Friction Stir Welds with Low Plasticity Burnishing: Residual Stress Design and Fatigue Performance Assessment (.pdf)
  Although friction stir welding (FSW). produces minimal distortion, residual stresses. are created that impact fatigue and stress. corrosion performance. X-ray diffraction residual. stress and cold work mapping methods used at. Lambda Research for FSW studies are. described. Post weld surface...
• Controlled Plasticity Burnishing to Improve the Performance of Friction Stir Processed Ni-Al Bronze (.pdf)
  Friction stir welding (FSW) allows the joining of aluminum alloys in ways previously unattainable offering new manufacturing technology. Friction stir processing (FSP) of cast alloys such as Ni-Al bronze eliminates casting voids and improves the properties to that of wrought material. However...

Friction stir welding (FSW) is a new solid state. with comparable fatigue performance regardless of salt. joining...
• Fatigue Life Improvement and Mitigation of Pitting Corrosion Damage of Friction Stir Welded 2219-T8751 Aluminum Alloy by Low Plasticity Burnishing (.pdf)
  Friction stir welding (FSW) is a new solid state joining process for aluminum alloys including those alloys considered not weldable. However, the FSW process produces zones of tensile residual stress at the edges of the stir zone. Recent residual stress studies performed at Lambda Research...
