The fin pass was not the first time your father gave you five bucks for your allowance. The fin passes are those forming passes that immediately follow the breakdown or initial forming stages on a tube mill. Their role is paramount in the successful final presentation of the formed tubular section to the welding process.

A coil end joiner, shear welder, end welder, coil splicer, strip welder, shear and end welder, or butt welder—whatever you call it, it performs the same simple task coil after coil: It quickly shears strip ends, butts them, and provides a smooth ductile weld so that the newly joined coil can pass through a tube mill.

It's Monday morning after a long holiday weekend, and the first shift is starting with a bang. The slit coil supplier is late with your delivery, the second-shift maintenance person has called in sick, the mill operator is going to be late to work, and you wish you were still at the beach with the family.

This article discusses three main criteria that govern tube mill tooling—design, materials used in their construction, and alignment of tooling on the mill. Discusses advancements in design due to CAD technology; experimental use of ceramic and plastic materials for making tooling; and the use of subplates and interchangeable components to ease tube mill alignment.
