Abstract
A method of forming a unitary metal piece includes providing first and second generally planar metallic portions. Each portion has generally parallel first and second sides opposite each other. Each portion has an end edge extending between the first and second sides. The first and second ends are proximate one another. The end edges are resistance welded together to form a weld joint and produce weld flash on at least one of the first and second sides of the portions. The weld flash on at least one of the first and second sides is ground, and a fluid is applied to the weld joint during the grinding of the weld flash.

A method of forming a unitary metal piece comprising:
- providing first and second generally planar metallic portions each having generally parallel first and second sides opposite each other, and each having an end edge extending between the first and second sides, where the first and second ends are proximate one another;
- resistance welding the end edges together to form a weld joint and produce weld flash on at least one of the first and second sides of the portions;
- grinding the weld flash on at least one of the first and second sides;
- and
- applying a fluid to the weld joint during the grinding of the weld flash.
A method of forming a band saw blade comprising:
- providing a generally planar blade backer having generally parallel right and left sides opposite each other, and having first and second ends opposite each other, and having top and bottom edges opposite each other and extending between the right and left sides and extending between the first and second ends;
- forming a plurality of teeth on the top edge of the blade backer;
- abutting the first and second ends;
- resistance welding the first and second ends together to form a weld joint and produce weld flash;
- grinding the weld flash on the right and left sides;
- and
- applying a fluid to the weld joint during the grinding of the weld flash.
A method of forming a unitary metal piece comprising:
- providing first and second generally planar portions of a metallic body having a crack or an opening in a body disposed between first and second ends of the portions;
- additively printing material in the crack or the opening to close the crack or the opening and join the portions together to form a continuous body and produce additively printed weld flash;
- grinding the additively printed weld flash;
- and
- applying a fluid to the additively printed material during the grinding of the additively printed weld flash.
