Abstract
A method for welding a pair of metal sheets together along an edge of each metal sheet is provided that includes the steps of: 1) determining a line for each of the edges to be welded using one or more sensors: 2) selecting one of the edges to be welded as a dominant edge and the other edge to be welded as a non-dominant edge: and 3) welding the metal sheets together along the dominant edge and the non-dominant edge. The present invention further includes an apparatus capable of performing the present method.
Claims7
A method for welding metal sheets to form tailored blanks, comprising:
- detecting the edge line of both sheets in the welding machine;
- identifying the edge line of one of the sheets as the dominant edge line;
- reworking the other edge to match it to the dominant edge;
- and
- then welding the sheet.
A method for welding a pair of metal sheets together along an edge of each metal sheet, comprising the steps of:
- sensing the edge to be welded of each metal sheet;
- determining a line for each of the edges to be welded;
- selecting one of the edges to be welded as a dominant edge, and the other edge to be welded as a non-dominant edge;
- reworking the non-dominant edge to substantially match the dominant edge;
- welding the metal sheets together along the dominant edge and the non-dominant edge.
A method for welding a pair of metal sheets together along an edge of each metal sheet, comprising the steps of:
- determining a line for each of the edges to be welded using one or more sensors;
- selecting one of the edges to be welded as a dominant edge, and the other edge to be welded as a non-dominant edge;
- determining if a gap between the edges to be welded exceeds a predetermined amount;
- replacing the metal sheet having the non-dominant edge with a replacement metal sheet;
- determining a line for the edge of the replacement sheet to be welded and repeating the step of determining a gap and also the step of replacing the metal sheet having the non-dominant edge, if necessary, until the gap is equal to or less than the predetermined amount;
- welding the metal sheets together along the dominant edge and the non-dominant edge.
