Abstract
Dissimilar materials joining between type 304 stainless steel and polycarbonate (PC) was carried out with fiber laser. Local interfacial strength was higher in the center of weld region. Bubbles might be formed in the center of weld region according to the temperature distribution. However, position of the maximum bubble size observed was not always in the center, but was nearby the edge of weld region in case of the joint with lower strength. The bubbles might move with flow of molten PC. It is considered that position of bubbles has significant effect on strength of the joint. Moreover, it is also speculated that distribution of interfacial strength and change in mechanical property of PC due to thermal degradation also can affect strength of the joint as a secondary effect to change crack propagation behavior.
