A weld filler material for fusion welding of high strength aluminum alloys, especially alloys of the AlZnMgCu type, contains 4.1-6.5% of zinc, 4.0-6.0% of magnesium, 0.3-0.6% of copper, 0.3-0.5% of manganese, at most 0.1% of titanium, at most 0.3% of chromium, at most 0.3% of zirconium, at most 0.1% of silicon and at most 0.3% of iron, the remainder being aluminum of commercial purity. The formation of cracks in the region of the weld seam can be prevented by means of the weld filler material. |
