The first component has a first joining surface arranged coaxially and in spaced juxtaposition around a second joining surface of the second component, such that a radial gap is defined between the first and second joining surfaces. Furthermore, at least one of the first and second joining surfaces comprises a circumferential groove. The intermediate joint is formed by metal material that substantially fills the radial gap, whereby a first portion (141) of the intermediate joint comprises metal material that has been plastically deformed to fill the circumferential groove. According to the invention, the intermediate joint comprises a second portion (142), formed by metal material that has been welded or brazed to the first joining surface and to the second joining surface. ## Claims ### Claim 1 An assembly comprising: a first component joined to a second component by means of an intermediate joint, the first component having a first joining surface arranged coaxially and in spaced juxtaposition around a second joining surface of the second component, such that a radial gap is defined between the first and second joining surfaces, at least one of the first and second joining surfaces providing a circumferential groove, the intermediate joint having metal material that substantially fills the radial gap, wherein a first portion of the intermediate joint is formed by metal material that has been plastically deformed to fill the circumferential groove, and wherein the intermediate joint provides a second portion, formed by metal material that has been one of either welded and brazed to the first joining surface and to the second joining surface. ### Claim 2 (depends on 1) The assembly according to claim 1, wherein the second portion of the intermediate joint provides the same metal material as the metal material of the first portion. ### Claim 3 (depends on 1) The assembly according to claim 1, wherein the second portion of the intermediate joint provides metal material that is different from the metal material of the first portion. ### Claim 4 (depends on 1) The assembly according to any one of claims 1, wherein the first and second portions include an insert ring with a volume that is essentially equal to the volume of the radial gap. ### Claim 5 (depends on 3) The assembly according to claim 3, wherein the first portion of the intermediate joint provides a first insert ring and the second portion provides a second insert ring. ### Claim 6 (depends on 1) The assembly according to claim 1, wherein the metal material of at least the first portion of the intermediate joint comprises a high-strength steel. ### Claim 7 (depends on 1) The assembly according to any preceding claim 1, wherein at least one of the first and second components is made of bearing steel ### Claim 8 (depends on 7) The assembly according to claim 7, wherein the metal material of at least the second portion of the intermediate joint comprises metal that has welding or brazing compatibility with bearing steel. ### Claim 9 (depends on 1) The assembly according to any preceding claim 1, wherein the circumferential groove is formed by a concave portion on one of the first and second joining surfaces and, radially opposite therefrom, the other of the first and second joining surfaces comprises a convex portion, such that the radial gap comprises an arcuate section. ### Claim 10 (depends on 9) The assembly according to claim 9, wherein an insert ring pressed into the arcuate section has a thickness in an undeformed state, which is equal to a maximum radial gap between the convex portion and the concave portion. ### Claim 11 A method of joining a first component to a second component, by means of an intermediate joint having metal material that substantially fills a radial gap between a first joining surface on the first component and a second joining surface on the second component, the method comprising steps of: providing a circumferential groove on one of the first and second joining surfaces; arranging the first component coaxially around the second component such that the first and second joining surfaces are radially opposite each other, the radial gap being formed therebetween; pressing a first metal insert ring into the radial gap, such that metal material of the ring plastically deforms to fill the circumferential groove; and wherein characterized in that, the method further comprises: one of welding and brazing metal material of the intermediate joint to the first joining surface and to the second joining surface. ### Claim 12 (depends on 11) The method according to claim 11, wherein the first metal insert ring has a volume substantially equal to the volume of the radial gap. ### Claim 13 (depends on 11) The method according to claim 11, wherein the first metal insert ring has a volume less than the volume of the radial gap and the method comprises a further step of pressing a second metal insert ring into the radial gap and the step of welding or brazing comprises welding or brazing metal material of the second insert ring to the first and second joining surfaces. ### Claim 14 (depends on 13) The method according to claim 13, wherein the first insert ring is made of metal material with a higher yield strength than the metal material of the second insert ring. ### Claim 15 (depends on 11) The method according to claim 11, wherein the first metal insert ring has a volume less than the volume of the radial gap and the step of one of welding and brazing further comprises a hybrid welding or brazing process in which a filler material is used to create the second portion of the intermediate joint.
