Zusammenfassung:Ribbed sheet steel casing, esp. for the housings of electrical rotating machines. The sheet is bent to form longitudinal running ribs or fins, for cooling purposes. The bends are hair pin shaped and are welded using electric arc welding at the root of the bend in the space (3). The welds are spaced at regular intervals pref. between 50 and 70 mm. The length of the individual welded seams is pref. 5 to 10 mm. The individual discontinuous welded seams (5) are arranged vertical to the horizontal plane of rib longitudinal axis and are positioned on the inside of the motor casing.
