Factors Affecting the Tensile Strength of Linear Vibration Welds of Dissimilar Nylons 2002-01-0604

Three different pairs of high melting temperature and low melting temperature nylons have been welded together using three different design of experiment welding process parameter matrices. An unorthodox analysis of these has revealed that there is a general increase in strength as the total welding sliding distance of the two surfaces increases. This is not surprising. The analysis also reveals that, for a given sliding distance, the vibration amplitude should be large, which shortens the welding time. This strategy produces shorter cycle times and stronger welds, according to the data obtained in these test sets.
