Meeting 11th Conference on Trends in Welding Research + Additive Manufacturing (TWR+AM)
Symposium 11th Conference on Trends in Welding Research + Additive Manufacturing (TWR+AM)
Presentation Title Linear Friction vs Linear Solid State
Author(s) Paul Cheng
On-Site Speaker (Planned) Paul Cheng
Abstract Scope Linear Friction is well known. Large energy input to generate heat and forge. Result: fusion line, grain flow at 90 degrees and sharp profile. Large equipment footprint. Linear Solid State places induction coil in-between work faces. Take to hot working temperature in an inert environment. Remove coil. Push and shear. Result: no fusion line (an assumption), smooth profile. Edges line up flush. Grain flow merge into each other (an assumption) similar to tubular solid state. Energy consumption is magnitudes less than friction. Equipment is size of two legal filing cabinets. Weld profile is repeatable. Samples at U Waterloo for analysis. Will have results by mid March. Have joined two steel plates ½” x 5”. Aim is to join thick to ultra thin; exotic and aluminum.
