“…They concluded that the minimum change of pitch static attitude (DPSA) and maximum shear strength was achieved in optimum levels of the process parameters. The effect of laser welding parameters such as welding speed, laser power, clamp pressure, and standoff distance on weld strength of dissimilar material (polycarbonate to acrylonitrile butadiene styrene) was investigated by Acherjee et al 14 The numerical and graphical optimization results show that low seam width and high weld strength were obtained in the optimal welding conditions. A similar observation was experienced by Wang et al 15 They observed that the weld strength of 45 MPa, a seam width of 3580 mm, and weld cost of 1.2¥ were obtained when laser power of 41 W, scan velocity of 10 mm/s, clamp pressure of 1 MPa, and scanning number of 2 were selected.…”

Laser welding and nanocomposites are finding increasing applications in industries. The polypropylene/ethylene-propylene-diene-monomer/clay nanocomposite has wide application in many industries. In this study, the effect of laser power, standoff distance, scan velocity, and clay content as input parameters on tensile and impact strengths of laser welds and welding operation cost as output parameters has been investigated using response surface methodology. The Box–Behnken design was employed to establish proper mathematical models relating input to output parameters. Morphology and dispersion of clay in the above nanocomposite have also been evaluated by X-ray diffraction and transmission electron microscopy. The results have been presented numerically and graphically. The results show that with laser power of 108.84–110.90 W, scan velocity of 566.18–597.19 mm/min, standoff distance of 8 mm, and clay content of 0.35–0.83 wt%, optimum values for tensile strength of 9.3 MPa, impact strength of 67.2 J/m, and welding cost of 30 cents/m are obtained. A minimum cost weld (18.5 cents/m) can be achieved when a proper combination of laser power of 108.53–109.80 W, scan velocity of 874.27–893.09 mm/min, standoff distance of 8 mm, and clay content of 0.75–0.94 wt% is selected.

Poly(methyl methacrylate) (PMMA) and poly(butylene terephthalate) (PBT) are widely used in industry; however, poor compatibility between two materials lead to poor weld strength. Polycarbonate (PC) has good compatibility with PMMA and PBT. Therefore, the welding method was that PC film as intermediate material was used to enhance weld strength in laser transmission welding (LTW) of PMMA and PBT. Through the LTW experiment, the weld strength was tested by mechanical testing and it was found that the best weld strength was improved more than four times than the weld strength without intermediate material. By observing the micro morphology of the weld zone, one reason was founded that the bubbles can be used to form micro‐mechanical riveting to enhance the weld strength. The reptation time for PMMA, PC, and PBT were investigated to analyze the establishment of the weld strength. When the reptation time is much shorter than time in molten state, the higher weld strength is feasible. It can be concluded that the weld strength of PC/PBT was higher than the weld strength of PMMA/PC. The equilibrium interfacial width was calculated through Helfand's theory to analyze the compatibility of dissimilar materials. The equilibrium interfacial width for PMMA/PC and PC/PBT were similar to tube diameter. That is the reason for weld strength enhancement. And then, the response surface methodology was designed to predict the weld strength.© 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 44167.

The present review provides an overview of the current status and future perspectives of one of the smart manufacturing techniques of Industry 4.0, laser transmission welding (LTW) of semi-crystalline (SC) polymers and their composites. It is one of the most versatile techniques used to join polymeric components with varying thickness and configuration using a laser source. This article focuses on various parameters and phenomena such as inter-diffusion and microstructural changes that occur due to the laser interaction with SC polymers (specifically polypropylene). The effect of carbon black (size, shape, structure, thermal conductivity, dispersion, distribution, etc.) in the laser absorptive part and nucleating agent in the laser transmissive part and its processing conditions impacting the weld strength is discussed in detail. Among the laser parameters, laser power, scanning speed and clamping pressure are considered to be the most critical. This review also highlights innovative ideas such as incorporating metal as an absorber in the laser absorptive part, hybrid carbon black, dual clamping device, and an increasing number of scans and patterns. Finally, there is presented an overview of the essential characterisation techniques that help to determine the weld quality. This review demonstrates that LTW has excellent potential in polymer joining applications and the challenges including the cost-effectiveness, innovative ideas to provide state-of-the-art design and fabrication of complex products in a wide range of applications. This work will be of keen interest to other researchers and practitioners who are involved in the welding of polymers.
