Abstract
A welding method includes welding a die cast mould part made of an Al—Mg—Fe alloy in a fluid-tight manner to at least one other metal part. A Mg content of 4%≤Mg≤4.6% and an Fe content of 1.31%≤Fe≤1.7% are used for the aluminum alloy, as well as an admixture content of additional alloying constituents comprising a maximum of 0.2% Si. A blue diode laser is used for welding. No filler metal is used. The welding method may be used to construct an actuator housing.
Claims5
A welding method, comprising:
- welding a die cast mould part made of an Al—Mg—Fe alloy in a fluid-tight manner to at least one other metal part,
- wherein for the Al—Mg—Fe alloy a Mg content of 4%≤Mg≤4.6% and an Fe content of 1.31%≤Fe≤1.7% are used, wherein the Fe content comprises an Al—Mg—Fe eutectic and a hypereutectic composition of alloy constituents Fe and Mg, as well as an admixture content of additional alloy constituents, which comprises a maximum of 0.2% Si, and
- wherein a blue diode laser and no welding filler material is used for welding.
