• When to Use Friction Welding
  Normal welding doesn't allow the combination of different materials; but friction welding does. Friction welds provide a strong bond without the use of bolts and/or screws or the addition of extra weight. Forging industry dynamics over the last few years have left many customers with lengthy lead...
• The Friction Welding Advantage
  inspection to ensure each part meets set parameters. Friction welding enabled another manufacturer of large construction equipment to find an alternative to its current source for axles. Only one company in the country provided the type of axle needed in the three different variations required; each...
• Causing a stir in welding
  where pieces are melted and resolidified to form a new and different material structure, friction stir welding produces solid-phase bonds between parts. The plasticized material is stirred and mixes across the joint boundary. This produces welds both strong and ductile, with up to twice the fatigue...
• Metal Coatings
  joined by spot welding and which require a smooth, Class A painted finish. Among today's improved galvanized steels is Inland Steel's Paint-Tite B family of three products. These galvannealed (heat-treated) steels have a hot-dipped zinc coating on one side and a light, gas-jet-wiped coating...
• 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...
• Electrohydraulic Controls Boost Thermal Drilling
  is particularly useful for making attachments to pipes which would otherwise require hardto- apply weld nuts or rivnuts, or have inadequate surface areas for soldering or welding. Authored by Kenneth J. Korane * Thermal drilling beats conventional drilling in thin metals and when weld nuts...
• Tin Vs. Bare
  in the fusion-welding processes, no molten phase is present or required to make the bond thus the term "cold" welding. Instead the metals bond by sharing electrons with each other. In a metal, groups of atoms readily `lose' electrons to form positive ions. These ions are surrounded by and share...
• Casing the extrusion joint
  compartment in Ford GT supercars. Some 35 different extruded profiles from form a stiff, strong, and lightweight platform. Chassis are assembled using a combination of robotic MIG and friction stir welding. In addition, bolt-on extrusions add structural support to the engine compartment and also...
• Fatigue Life Improvement of Welded Elements by Ultrasonic Peening
  energy, or high power ultrasonics have found. practical use in many industrial processes, of which cleaning, welding and drilling are well-. known examples. Other applications include metal forming, treatment of molten metals,. 2. chemical processing, and even therapeutic and surgical uses...
• Hinge Optimization
  . To hold a door or cover open (friction type). HINGES. HINGE SELECTION. EMKA manufacturers over 130 different hinges all designed for metal. enclosures. Thus a design engineer has many options from which to select. a hinge that gives all the functionality that his customers want with the. installation...
