The concentrated solar power plant technology has been proven to be a latest source for generation of renewable energy. Its performance depends on efficiency of the parabolic trough receiver tube or heat collecting element (HTC). In this paper, experimental study on fabrication of glass metal joint has been elaborated for parabolic trough receiver tube. Borosilicate glass tube was joined with austenitic stainless steel (SS304) metal ring using compression glass-metal type assembly with the help of induction heating and using 40SiO 2 -54B 2 O 3 -4Na 2 O-2Al 2 O 3 material as the glass sealant. The process parameters for joining were selected on the basis of wettablity, pre-oxidation and microstructure studies. The generated residual stresses in glass tube after fabrication process was measured experimentally with the help of photo elastic technique using polariscope 'PS-100-BS'. From the experimental results, it was observed that, the intensity of residual tensile stress in glass tube increases as thickness of metal ring increases. The cracking of glass just 1mm above the interface was also observed corresponding to maximum metal thickness ring. © 2018 Elsevier Ltd. All rights reserved.
