It was studied that two plates of aluminum can be welded by extru-riveting experiments by electric resistance heated method, and that the welding strength and metal flow on the welding section were analyzed by computer simulation according to the welding variable such as the welding current and welding time. And it was known heat distribution is calculated using a DEFORM-3D software. It was known by computer simulation that welding strength on the welding section of plates could be influenced by the the welding current and time, and that welding strength is the highest when welding current is 37㎄ and welding time is 90cycle, when aluminum 5052 two plates with 1㎜ thickness and one plate with 2㎜ thickness for inserting rivet plate are used in extru-riveting spot welding process.
