Abstract
Fusible sheet edges are joined by first forming each of the edges with a laterally projecting burr and then butting the edges together at a join line with both the burrs directed in the same lateral direction adjacent each other and plastically deforming the laterally projecting burrs at the join line in the lateral direction opposite their projection direction. Finally the edges are fused together at the join line. The burrs are plastically deformed by pressing them with a barrel-shaped roller that is moved along the join line.
Claims8
A method of joining fusible metal sheet edges, the method comprising the steps of sequentially:
- forming each of the edges with a laterally projecting burr;
- butting the edges together at a join line with both the burrs directed in the same lateral direction adjacent each other but with some small gaps remaining between the butted edges;
- plastically deforming the laterally projecting burrs at the join line in the lateral direction opposite their projection direction and thereby closing the gaps;
- and
- directing a laser beam at the join line and thereby fusing the edges together at the join line.
A method of joining fusible metal sheets, the method comprising the steps of sequentially:
- shearing the sheets to form a pair of sheet edges each with a laterally projecting burr;
- butting the edges together at a join line with both the burrs directed in the same lateral direction adjacent each other but with some small gaps remaining between the butted edges and supporting the side of the workpieces at the join line opposite the burrs on a support;
- plastically deforming the laterally projecting burrs at the join line in the lateral direction opposite their projection direction by pressing the burrs toward the support and thereby pressing the burrs into the gaps to close same;
- and
- directing a laser beam at a join line and thereby fusing the edges together at the join line.
