..., operating parameters were selected for welding across a 12.7 μ m gap and a 25.4 μ m gap by creating sufficient thermal strain to bridge the gap and form a weld. Using these operating parameters, PVC samples were welded in a T -joint geometry with a designed gap. The quality of the welds was assessed...

... in Table 4 . All 64 samples in this experiment produced a weld between the two PVC parts. As in the previous experiment, these samples were assessed by three methods: the visual appearance, the maximum tensile force at failure, and the measured width of the weld. However, in contrast to the previous...
