Literature
Computer Simulation for Laser Welding of Thermoplastic Polymers [1]
Abstract: This paper presents an analytical approach to thennal behaviors of laser welding of polymers. Laser polymers processing leads to various thennal, photophysical, and photochemical processes within the bulk and on the material surface. The understanding of these processes is beneficial to obtaining the high quality precision engineering of polymers. The Green's function of a multi-layer plate for the transient heat transfer is utilized to analyze the laser welding of PMMA and ABS/PC. The results indicate that the measured temperatures agree well with the calculated temperatures near laser source. The model proposed by this paper is applicable to the temperature prediction of the laser welding for polymers.:
Keywords: Green's function methods, heat transfer, laser beam welding, polymers, thermal analysis, ABS/PC, Green's function, PMMA, computer simulation, temperature prediction, thermal analysis, thermal
Summary:
- Linear laser welding of ABS/PMMA systems
- Numerical modeling simulations
- Determination of critical surface temperatures for welding. Calculations correlate to experimentally acquired data.
Laser welding of thin polymer ®lms to container substrates for aseptic packaging [2]
Abstract: Keyhole laser welding of polymers is a subject well covered and researched, but relatively little information exists regarding the welding of thin polymer ®lms, particularly to a heavier substrate. This paper presents the design of a suitable test apparatus for laser welding thin ®lm to a heavier substrate, and shows the results of an investigation into the feasibility of laser welding multi-layer polymer ®lm lids to tubs for the manufacture of aseptic food containers. A consistent weld, free from defects, is the key to process success. Typical welding defects have been synthesised in order to investigate, and consequently remove, their cause. The result is a reliable welding method based on even ®lm clamping. With careful attention to machine design, a seal of high mechanical strength and chemical integrity is possible. 7 2000 Elsevier Science Ltd. All rights reserved.

- Characterization of mechanical strength and chemical integrity
- Non-Contact Sealing
- Gaussian Weld Effect Region
- Peel adhesion testing
Industrial applications of high power diode lasers in materials processing [3]
Abstract: Diode lasers are widely used in communication, computer and consumer electronics technology. These applications are based on systems, which provide power in the milliwatt range. However, in the mean time high power diode lasers have reached the kilowatt power range. This became possible by special cooling and mounting as well as beam combination and beam forming technologies. Such units are nowadays used as a direct source for materials processing. High power diode lasers have entered the industrial manufacturing area [Proceedings of the Advanced Laser Technologies Conference 2001, Proc. SPIE, Constanta, Romania, 11–14 September 2001].
