とかわかる。As is clear from Table 4, when the aluminum alloy filler material of Present-11 was used, no weld cracking occurred and no beat marks were transferred from the photoetched surface. However, weld cracks occurred with the comparative alloy, and beat marks were transferred when molded using a photoetched mold. When conventional alloys were used, alloy 2319 caused weld cracks and beat trace transfer, and alloy 5356.4o43
When using welding; 13, either no damage occurred or transfer of beat marks appeared, both of which were bad. From the results shown below, it can be seen that when MIG welding and TIG welding were performed using the alloy filler metal of the present invention, only welds 1 and 1 occurred, and no beat marks were transferred.

ものである。(Effects of the invention) When welding aluminum alloy molds (Al-Zn-Mg-Cu alloy) for molding plastics, rubber, etc. using unexploited 1!1 filler metal, only weld cracks occur, and there is no photo-resistance. When etched, a good surface is obtained that does not transfer welding beat marks to molded products such as plastics and rubber. The filler metal of the present invention is ', f! It can also be used for i-tools and structures. As described above, the filler metal of the present invention has two remarkable effects in industry.
