PYROMETER MEASUREMENTS DURING LASER WELDING OF THERMOPLASTIC ELASTOMERS TO POLYPROPYLENE AND OF NYLON TO ITSELF

摘要

Pyrometer measurements were collected during the contour through-transmission laser welding of thermoplastic elastomers to glass-filled polypropylene as well as of unfilled nylon to itself. The elastomer-to-polypropylene samples were in shear-lap configuration whereas the nylon welds were between a ribbed flange and a web, representing a modified T-weld. Trends observed in the pyrometer readings are reported for both of these cases.
