Research on Welded Thin NiTi Wires and Orthodontic Bands

Abstract:

NiTi welded joints in the form of wires or thin blades are used in orthodontic appliances. Problems arise due to welding heat transfer sections specifically reduced. The research is focused on the welding flame, laser and ultrasound. The main objective is to define the characteristics of use of welded joints based on mechanical testing of tensile, hardness determination, metallographic examination. The study was enjoyed on a statistical interpretation of results. The results highlight the comparative strengths, weaknesses of the processes used respectively. It highlights opportunities offered by laser welding process is related to the flame, i.e. ultrasound.
