Weldcoupling method of aluminum die-cast material and aluminum wrought material

摘要

The present invention relates to a welding coupling method of an aluminum die cast material and an aluminum whole body material, when the aluminum die cast material 20 and the aluminum whole body material 30 are overlapped and welded to be welded to a welding bead 40 in a molten pool. When it is possible to delay the cooling rate and the solidification rate of the molten pool, it is possible to eliminate the phenomenon that the hardness of the aluminum body material 30 is weakened thereby welding the aluminum die cast material 20 and the aluminum body material 30 Increasing bond strength and preventing cracks. In addition, when welding the aluminum die-cast material 20 and the aluminum whole material 30 in a T-shape, it is possible to greatly improve the strength of the weld joint by increasing the depth D2 of the welding bead 70. In addition, productivity is improved through improved appearance and high work speed.
