Abstract
A tack welding method for use with a hybrid laser arc welding process. The method provides a recess on an edge of a first piece. The edge of the first piece is configured to cooperate with a second piece. The method positions the first piece relative to the second piece so as to provide a gap between the first piece and the second piece. Subsequently, the method provides a tack weld within the recess of the first piece. The recess is configured to accommodate placing the tack weld at a root of the gap.
Claims20
A welding method for joining a first piece and a second piece, the method comprising:
- providing a recess on an edge of the first piece, the edge of the first piece configured to cooperate with the second piece;
- positioning the first piece relative to the second piece so as to provide a gap between the first piece and the second piece;
- and
- providing a tack weld within the recess of the first piece, wherein the recess is configured to accommodate placing the tack weld at a root of the gap.
A welding method for joining a first piece and a second piece, the method comprising:
- providing a recess on an edge of the first piece, the edge of the first piece configured to cooperate with the second piece;
- positioning the first piece relative to the second piece so as to provide a gap configured to define a narrow J-groove between the first piece and the second piece;
- and
- providing a tack weld within the recess of the first piece, wherein the recess is configured to accommodate placing the tack weld at a root of the narrow J- groove.
A welding method for joining a first piece and a second piece, the method comprising:
- providing at least one recess on an edge of the first piece, the edge of the first piece configured to cooperate with the second piece;
- positioning the first piece relative to the second piece so as to provide a gap between the first piece and the second piece;
- providing a tack weld within the at least one recess of the first piece by filling at least a portion of the at least one recess with weld material, wherein the at least one recess is configured to accommodate placing the weld material at a root of the gap;
- and
- joining the first piece and the second piece by forming a seam using a hybrid laser arc welding method, wherein the hybrid laser arc welding method includes directing a laser beam at the root of the gap and depositing weld material within the gap with a gas metal arc welding torch.
