Abstract: The connection between the front hood panel and the inner panel is mainly realized through the hemming process, while the complex process of the front hood inner panel assembly, plate thickness, equipment sharing and cost etc. This paper mainly combines with the actual processing efficiency, equipment commonality, cost and other factors to analyse the advantages and disadvantages of these current connection process such as spot welding, self piercing riveting (SPR), clinch and so on. The results show that in the selection of process, which should not only consider the characteristics of the material itself, but also consider the characteristics of various processes and the process characteristics of the line and body shared model products, so as to achieve cost reduction and maximum equipment benefit.

Key words: Front hood inner panel; SPR; Clinch; Connection process
