Development of P.C. based Weld Monitoring System for Flash Butt Welding of Economiser Tubes

Flash butt welding is used extensively for welding of steel for different applications ranging from rails to automobile wheels in our country. Although this process is widely used for past six decades, there is still apprehension in adaptation of this process in certain critical applications for want of proper reliable N.D.T. method or proper quality assurance method. The present work addresses this problem of reliable N.D.T. method by suggesting the adaptation of computer based parameter monitoring system for checking every production joint. The first part of the work discusses the development of a P.C. based weld monitoring system. The second part of the work discusses the evaluation of the performance of the developed monitoring system in the actual production environment by welding economiser tube joints.
