Process for manufacturing a composite cast part, and composite cast part
View Patent ↗Process for manufacturing a part, in particular a composite cast part, includes the steps of: providing at least one insertion element; casting a casting material around at least a portion of the at least one insertion element such that at least one contact area is formed between the at least one insertion element and the casting material; and welding the at least one insertion element to the casting material in the contact area.
1. A method for producing a component or a component connection, comprising:
providing at least one insert element;
encapsulating at least certain regions of the at least one insert element with a cast material, wherein at least one contact region is formed between the at least one insert element and the cast material; and
welding at least certain regions of the at least one insert element to the cast material in the contact region away from a location at which the encapsulated portion of the at least one insert element ends and a not-encapsulated portion of the at least one insert element begins.
2. The method according to claim 1 , wherein the act of welding comprises:
pressure welding in the contact region.
3. The method according to claim 1 , wherein the act of welding comprises:
friction stir welding in the contact region.
4. The method according to claim 1 , wherein the contact region has at least two contact surfaces, the method further comprising:
welding the at least two contact surfaces to the cast material.
5. The method according to claim 4 , wherein
the at least two contact surfaces are opposite contact surfaces.
6. The method according to claim 1 , further comprising:
forming a punctiform and/or linear weld seam.
7. The method according to claim 1 , wherein the act of encapsulating comprises:
encapsulating in a die-casting operation.
8. The method according to claim 1 , further comprising:
performing a heat treatment before the welding.
