چکیده مقاله
Ultrasonic welding is considered as a rapid joining process Recently application of this method in joining of polymeric parts is increasing Applicability of this method in joining of thermoplastic materials is confirmed by many researchers However a few researches have been conducted on applicability of ultrasonic method in joining of thermosets On the other hand ultrasonic welding of polymeric welded materials specially thermosets may have challenges One of the major challenges could be the existence of various defects such as detachments, voids and incomplete fusion Consequently ultrasonic welding of polymeric parts shall be continued by inspections Numerous nondestructive testing NDT methods are introduced to inspection of polymer based materials Active IR Thermography is one of the well known NDT methods in inspection of polymer based materials and polymer based composites Therefore it can be used to inspection of welded polymeric parts In present research two polymeric parts made of glass fiber reinforced epoxy were joined by ultrasonic welding At the next stage IR thermography was employed to inspection of welded parts with artificial defects and the applicability of IR thermography in detection of various types of defects were investigated
