Punktowe spawanie laserowe z transmisją jest ważną technologią spawania ze względu na jej szerokie zastosowanie w dziedzinie spawania. Zastosowano maszynę laserową 3D CNC z laserem diodowym 1064 nm. Spawano dwa rodzaje polimerów (PMMA i PVC) dla różnych (grubości, czasu spawania laserowego i ciśnienia docisku próbek) przy mocy lasera 3,29 W. Wykonano skanowanie i przezroczystośc spektroskopii w podczerwieni z transformacją Fouriera dla każdego polimeru. Zbadano wytrzymalośc na rozciąganie i mikrostrukturę dla każdego punktu spawania. Zaobserwowano, że najlepszy czas spawania laserowego dla wszystkich spawanych elementów wynosil 5 sekund dla badanych elementów. Przeprowadzono proces spawania grup PMMA. Zaobserwowano, że wytrzymalośc spawania wzrastala wraz ze wzrostem czasu pracy lasera i ciśnienia docisku odpowiednio do (5 s, 5 bar). Dla grubości 2,50 mm najlepsze warunki dla czasu spawania laserowego i ciśnienia docisku wynosily odpowiednio (4 s i 5 bar). Podczas gdy dla grubości 6,00 mm, najlepsze warunki dla czasu spawania laserowego i ciśnienia docisku wynosily odpowiednio (5 sekund i 5 barów). Podobne wyniki uzyskano dla grup PVC o grubości (1,00 i 0,70) mm.
