ONE-PIECE ELBOW HYDRAULIC FITTING DESIGNED FOR ELECTRIC ARC STUD WELDING AND PROCESS FOR PRODUCING THE SAME
A process of forming a hydraulic port weld stud that includes providing a billet of material; forging an initial forging from the single billet of material including a stud portion having a longitudinal axis and a port portion extending along an axis transverse to the longitudinal axis of the stud portion; and machining the initial forging to form a finished part wherein the port portion and stud portion are integrally formed without the need for a joining operation.
1 . A process of forming a hydraulic port weld stud comprising:
providing a single billet of material;
forging an initial forging from the single billet of material including a stud portion having a longitudinal axis and a port portion extending along an axis transverse to the longitudinal axis of the stud portion;
machining the initial forging to form a finished part wherein the port portion and stud portion are integrally formed without the need for a joining operation.
2 . The process of claim 1 wherein the machining step includes forming a first bore along the longitudinal axis less than an entire length of the stud portion.
3 . The process of claim 2 wherein the machining step includes forming the first bore through a top surface and extending along the longitudinal axis towards a base less than a distance to the base and terminating at a pilot portion.
4 . The process of claim 2 wherein the machining step includes forming a hole in the base and press fitting a flux material into the hole.
5 . The process of claim 2 wherein the machining step includes forming a counter bore in the first bore.
6 . The process of claim 2 wherein the machining step includes forming threads in the first bore.
7 . The process of claim 2 wherein the machining step includes forming a chamfer in the first bore.
8 . The process of claim 1 wherein the machining step includes forming in the port portion a second bore extending along the transverse axis and intersecting the first bore of the stud portion.
9 . The process of claim 1 wherein the port portion includes either a male or female attachment port.
10 . The process of claim 9 wherein the male attachment port includes a generally cylindrical body and including forming threads on an outer surface of the generally cylindrical body.
11 . The process of claim 9 wherein the male attachment port includes a generally cylindrical body and including forming a flared end on the generally cylindrical body.
12 . The process of claim 9 wherein the female attachment port includes a generally cylindrical body and including forming threads on an inner surface of the generally cylindrical body.
13 . A process of forming a hydraulic port weld stud comprising:
providing a single billet of material;
shaping the single billet of material providing a stud portion having a longitudinal axis and a port portion extending along an axis transverse to the longitudinal axis of the stud portion;
machining the shaped billet to form a finished part wherein the port portion and stud portion are integrally formed without the need for a joining operation.
