Dynamic stresses produced by sonic boom pressure pulses in loose fitting windows, analyzing likelihood of breakage due to rattling
Generation of intense sonic and ultrasonic power in the weld zone, close to the puddle, reduces the porosity and refinement of the grain. The ac induction brazing power supply is modified with long cables for deliberate addition of resistance to that circuit. The concept is extensible to the molding of metals and plastics.
