[0012] That is, the connection strength of the welded part is proportional to the thickness (D1) of the weld (13). Welders cannot arbitrarily increase the welding thickness. If welding is repeated two or three times, not only the appearance will be affected, but also the work efficiency will be reduced.
Therefore, using the welding method of the prior art, due to the existence of the factor of the thickness (D1) of the weld seam (13), the welding strength of the aluminum die casting (11) and the aluminum forging (12) is reduced

Embodiment Construction
[0025] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0026] According to the present invention, the aluminum die casting 20 and the aluminum forging 30 are stacked up and down for welding as follows: Figure 4 shown. One side of the aluminum die casting 20 is provided with an opening installation groove 21; based on the installation groove 21, an upper flange 22 and a lower flange 23 are provided, and the length of the upper flange 22 is less than the length of the lower flange 23; One end of the aluminum forging 30 is loaded into the installation groove 21, so that the aluminum die casting 20 and the aluminum forging 30 are stacked up and down, and finally, the end of the upper flange 22 of the al...

The invention relates to an aluminium die casting and a welding method of aluminium forging materials. When the aluminium die castings and the aluminium forging materials are stacked up for welding, the cooling speed and the solidification speed of a molten pool surface when the molten pool is shifted into a welding line are reduced, thereby the hardness of the aluminium forging materials can be prevented from being reduced, and the aluminium forging materials can be prevented from cracking, and the welding strength of the aluminium forging materials and the aluminium die castings is greatly improved. When the aluminium forging materials and the aluminium die castings are welded in a manner of T-shaped structure, the thickness (D2) of the welding line can be increased by one welding, thereby the welding strength of the aluminium forging materials and the aluminium die castings is greatly improved, the appearance of the welding and the work efficiency are both improved.
Description
technical field [0001] The invention relates to a welding technology of an aluminum die casting and an aluminum forging. Background technique [0002] Generally, aluminum die castings and aluminum forgings are stacked up and down for welding. like figure 1 As shown, the aluminum die casting (1) is on the top, and the aluminum forging (2) is on the bottom, and welding is performed in this state. [0003] like figure 2 As shown, if the aluminum die casting (1) is on the bottom and the aluminum forging (2) is on the top, then when welding is performed in this state, cracking will occur at the stress concentration zone (3a) of the weld (3), Therefore, it is easy to cause damage to the aluminum die casting (1). [0004] That is, the aluminum die casting (1) is a heat-treated workpiece. The heat-treated workpiece is subjected to the heat generated during welding, and its hardness will become smaller. Then, when the molten pool (the weld is in a liquid state) solidifies and sh...
