Abstract: Through Transmission Laser Welding (TTLW) of plastic material is an emerging area of research and welding of plastic.
This paper reports transmission laser welding on acrylic plastic materials by using a diode laser system.
· Through Transmission Laser Welding may prove to be more useful and effective through proper selection of process parameters and judiciary choice of the materials.

Secondary processing of technogenic materials is facilitated by the fact that they are preprocessed – ground and compactly deposited on the surface, but complicated by the low (compared to ores) grade, uneven distribution of the valuable minerals, altered and unstable material composition of the mineral feed.
