Durability improvements of Exhaust pipe joints during operating Condition

Medium and Heavy Commercial Tipper vehicles in India are mainly used for off-road and mining applications where the vehicles are subjected to severe and irregular road load patterns. In such cases it is imperative that quality of weld joints in Exhaust pipes should be capable of withstanding off road duty cycle. The negative impact of any kind of defect will be magnified due to presence of such harsh road & environment conditions. The current paper focus discussion on the various failures and defects found in weld joints of exhaust pipes. Various methodology has been introduced to detect the modes of Weld failure. After detailed study and analysis, a set of recommendations are proposed for welding of Exhaust pipe flange joints to ensure high durability life of weld joints
