Method for separating a flat pipe section of aluminum or aluminium alloy from a solder-coated thin-walled flat pipe section member

摘要

In a method for separating a flat pipe section of aluminum or an aluminum alloy from a solder-coated, thin-walled flat pipe section member for producing a clean, bur-free separating cut, the solder coating is first mechanically removed from the flat pipe section member at a predetermined separating location, preferably by means of a cutting tool and, subsequently, the flat pipe section member is cut with at least one sharp cutting blade at the predetermined separating location to perform a notch thereat, wherein the notch depth is up to 0.3 mm, preferably 0.1 mm.
