Abstract

A pressure-resistant tank for liquids includes a plurality of differently shaped diecast parts (1, 2) made of a first aluminum alloy (cast alloy). The diecast parts (1, 2) are connected by means of a closed weld seam welded with an electron beam with the use of a second aluminum alloy (wrought alloy). The second aluminum alloy has especially a hydrogen content of less than 0.2 mL per 100 g of wrought alloy. The tank for liquids is especially an anesthetic tank and the anesthetic is desflurane.
