Abstract:

The fatigue evaluation of metal active gas(MAG)-welded thin-sheet structure is the main problem for chassis structure design, fully understand and master the fatigue property of thin-sheet structure is the foundation to predict the fatigue life. Through a series of sheet welded structure fatigue tests, some laws were summarized, that shows the effects of sheet metal strength, sheet metal thickness and welding manufacturing process on the weld fatigue performance, it makes a solid foundation for MAG-welded thin-sheet structure fatigue resistance design.

Key words: seam weld, fatigue life, seam welded thin-sheet structure, fatigue test
