Simulation, design, implementation and control of a welding process using micro-controller

This paper presents the design, fabrication of a microcontroller based resistance welding system which is used for performing a welding process. The paper is divided into 4 sections. First, a brief introduction to what is a welding, method of welding control such as resistance and spot welding is given. Secondly, the critical factors in the design of a welding process are dealt along with the principle of the welding process. Following this, the introduction to the design of the control scheme employed by us with the basic block diagram of the welding system and the functioning is presented. Thirdly, the design and development of the control software algorithm is dealt with. Finally, the conclusion is drawn along with its working and future improvements.
