Abstract: The uses of data network in a control loop have gained increasing attentions in recent years due to cost effective and flexible applications. But, still the major challenges in this networked control system (NCS) are the delay of the data transmission throughout the communication network. Therefore, this paper presents an analysis of the time delay in NCS and also the development of the NCS platform based on well known communication networks, which is, Controller Area Network (CAN).

Abstract: Influence of the process parameters on the weld deposit area and microstructure have been studied using bead on plate submerged arc welding process. It was found that the weld deposit area was affected by weld parameters like welding wire feed rate, welding speed, open circuit voltage, and contact-tube-to-work distance. The effect of welding current on weld deposit area has been studied independently by making a separate model for welding current. This is due to the fact that it is not possible to control the current in welding in semi-automatic processes unless it is a constant current welding process. Since the open circuit voltage was also one of the parameters, therefore, controlled variation of both the parameters wasn’t possible. The current automatically adjusts to a value at which the burn off rate and the wire feed rate are in equilibrium. To establish a relationship between weld deposit area and the welding parameters, two-level half-fractional factorial design was used. The
