The disclosure relates to a device () and a method for machining at least one surface of a continuous strip material (B) made of non-ferrous metals, which in particular comprises aluminum or aluminum alloys or consists of such materials. A rotating roller brush () is used, the roller length of which can be brought into contact with a surface of the strip material (B). Such roller brush () has a diameter of 200 mm to 1,000 mm and can rotate at a rotational speed of 100 to 3,600 rpm using an assigned motor drive ().

A butt joint deep penetration laser welding method is used for joining facing end sections of flat steel products, each having a carbon content CS<0.02%. In order to improve such a method such that an improved weld quality in terms of geometry and strength is achievable with it, at least one carbon-containing carrier material is inserted into a butt joint gap between the end sections, the carbon content of which is C≥20·C, preferably C≥100·C, and/or carbon is inserted into the butt joint gap or applied to at least one end section, such that the volume of the carbon inserted into the butt joint gap corresponds to 1% to 20% of the volume of a melt produced by a butt joint deep penetration laser welding process.

Butt-joint deep penetration laser welding method

A support roller, particularly for rolling mill systems or equipment for casting, conveying or straightening metal products, including a cylindrical roller axle, a hollow cylindrical outer ring arranged concentrically in relation to the roller axle, and a plurality of rolling bodies arranged between the roller axle and the outer ring. The roller axle further including a cavity, at least in certain sections between its central axis and a load introduction point. Due to the provision of the cavity the load rating and the service life of the support roller are increased.
