Abstract
Laser weld bonding of DP590 du phase to 6,016 uminium loy is studied in -on-uminium overlap configuration. Microstructure, hardness distribution and mechanic properties of the welding joint are anysed. Results reve that some defects, such as pores, cracks and softening in heat affected zone (HAZ), can be avoided in welding joints, and welding penetration depth and width increase compared with those of laser welding. The therm conduction rate mounts up and the cooling rate of the welding joint ascends, laser energy is more absorbed by the lower uminium loy, which leads to element diffusion suppressed from the lower to the upper, and the content increasing in both sides of the weld in the molten state. The transverse area has increased in jointing to uminium, and the shear load are shared by the adhesive and the weld, hence the mechanic properties of welding joint are significantly improved.
