Impact of Process Modelling on Current Direction of Welding Research and Future Targets

The present paper gives a description of process modelling and its impact on current direction of welding research and future targets. It analyses the research work carried out in the filed of process modelling and presents quantitative analysis. The present work classifies and subsequently quantifies the welding research on the basis of approaches including modelling and simulation, product development, cause-effect analysis and sensor and control. The analysis indicates that modelling based research is primarily reported for existing technologies and existing materials. Research in new technologies using modelling is still is in developing stages and new materials based research is primarily carried out with cause-effect based analysis. The paper also mentions the future targets in welding research and indicates the role of process modelling in achieving the targets.
