摘要: Friction plug welding, a recent variation of friction welding is process joining two similar or dissimilar materials. The joint efficiency can be enhanced by applying external heat source pre-heating at the work piece surfaces. Heat flux generation intermediate surface computed due to between materials considering co-efficient friction. land width varied varying diameter find its effect on temperature profile. Analytical modeling carried out with and without pre-heating. Temperature distribution in was calculated for different values ranging from 300oC-600oC. It observed that while decreasing there linear fall With preheating, higher peak achieved less time. High quality weld could processing
