Abstract

In the automotive industry, the use of thermoplastic and laser transmission source in vehicle lighting systems stands out because of the superior properties, and it is widely used in production and joining processes. However, as the process parameters directly affect the welding quality, it is very important to determine their effects. In this study, 2,7 mm thick Acrylonitrile butadiene styrene (ABS) and transparent Polymethyl methacrylate (PMMA) materials are combined with LPKF Twinweld 3D 6000 laser device. The effects of laser power, pressure force and feed rate, which are important parameters in laser transmission welding, are investigated. Lab-joint welding is performed with ABS and PMMA materials at 20-50 W laser power, 30-150 mm /s laser speed and 55-85 N pressure force. Samples combined in different parameter combinations are subjected to tensile tests, their mechanical strengths are examined and correlate with the parameters. As a result of the tests, the highest average mechanical strength and average elongation at break are obtained in the combination of 30 W, 70 mm/s and 70 N parameters. When all other parameters are kept constant, it is seen that the most effective parameter on mechanical strength is laser power.

Özet

Otomotiv endüstrisindeki araç aydınlatma sistemlerinde kullanılan termoplastik malzemelerin birleştirilmesinde lazer iletim kaynağı üstün özellikleri nedeni ile öne çıkmaktadır. Ancak, proses parametreleri kaynak kalitesini doğrudan etkilediği için etkilerinin tespit edilmesi oldukça önemlidir. Bu çalışmada 2,7 mm kalınlığındaki Akrilonitril bütadien stiren (ABS) ve şeffaf Polimetil metakrilat (PMMA) malzemeler LPKF Twinweld 3D 6000 lazer cihazı ile birleştirilmiştir. Lazer iletim kaynağındaki önemli parametreler olan lazer gücü, baskı kuvveti ve ilerleme hızının etkileri incelenmiştir. Yapılan çalışmada lazer gücü 20-50 W aralığında, ilerleme hızı 30-150 mm/s aralığında ve baskı kuvveti 55-85 N aralığına çalışılmıştır. Farklı parametre kombinasyonlarında birleştirilen numuneler çekme testlerine tabi tutularak mekanik dayanımları incelenmiş ve parametreler ile ilişkilendirilmiştir. Yapılan testler sonucunda en yüksek ortalama mekanik dayanım ve ortalama kopma uzaması 30 W, 70 mm/s ve 70 N parametre kombinasyonunda elde edilmiştir. Diğer tüm parametrelerin sabit tutulduğu durumda mekanik dayanım üzerindeki en etkili parametrenin lazer gücü olduğu görülmüştür.
