Abstract
A reworkable laser welding process for welding a first element to a second element.
Claims10
A method for fully erasing a laser spot weld, comprising the step of subjecting the spot weld to laser ablation such that the spot weld is fully ablated.
A method for welding a first element to a second element, comprising the steps of:
- (1) subjecting a contact point between the first element and the second element to laser radiation such that a first spot weld is formed;
- (2) subjecting the first spot weld to laser ablation such that the first spot weld is fully ablated;
- and
- (3) subjecting a contact point between the first element and the second element to laser radiation such that a second spot weld is formed.
A method for partially erasing a laser spot weld, comprising the step of subjecting the spot weld to laser ablation such that the spot weld is partially ablated.
A method for welding a first element to a second element, comprising the steps of:
- (1) subjecting a contact point between the first element and the second element to laser radiation such that a first spot weld is formed;
- (2) subjecting the first spot weld to laser ablation such that the first spot weld is partially ablated;
- and
- (3) subjecting a contact point between the first element and the second element to laser radiation such that a second spot weld is formed.
A method for welding a first element to a second element, comprising the steps of:
- (1) subjecting a first contact point between the first element and the second element to laser radiation such that a first spot weld is formed, and subjecting a second contact point between the first element and the second element to laser radiation such that a second spot weld is formed;
- (2) subjecting the first spot weld to laser ablation such that the first spot weld is at least partially ablated;
- (3) subjecting the second spot weld to laser hammering such that the position of the first element is adjusted relative to the second element;
- and
- (4) subjecting a third contact point between the first element and the second element to laser radiation such that a third spot weld is formed.
