The effects of varying laser-welding parameters were studied for the welding of the thermoplastic elastomer EPDM to glass filled polypropylene. Through-thickness scanning transmission welding (contour welding) was carried out with a diode laser with a wavelength of 940 nm using various power levels up to 150W and line speeds up to 2500 mm/minute. The observable weld attributes: weld strengths, weld widths, and failure modes, have been tabulated and discussed.
