Abstract
Abstract A welding tip for a cutting torch is made by forming a cylindrical head with a central stem at one end and an axial socket in the other end, and a ring of drilled passages extending from inlets around the base of the stem to the inner end of the socket. A solid rod with an inner end portion that will fit snugly in the head socket is drilled to provide it with a single passage lengthwise through it to form a nozzle. This passage is reamed to taper it from the inner end of the rod substantially to its outer end and to provide the large end of the passage with a diameter great enough to register with the inner ends of all of the head passages when the nozzle is inserted in the socket and sealed therein.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
157 words
The method of making a welding tip, comprising forming a cylindrical head with a central stem at one end and an axial socket in the other end and a ring of drilled passages extending from inlets around the base of the stem to the inner end of the socket, providing a solid rod that has an inner end portion that will fit snugly in said socket, drilling a single passage lengthwise through said rod to form a nozzle, reaming the nozzle passage to taper it from said inner end of the rod substantially to its opposite end and to provide the large end of the passage with a diameter great enough to register with the inner ends of all of said head passages when said inner end is inserted in the socket, inserting in said socket the end of the nozzle provided with the large end of the tapered passage, and sealing the nozzle in the socket.
Claim 2
Independent Claim
157 words
The method of making a welding tip, comprising forming a cylindrical head with a central stem at one end and an axial socket in the other end and a ring of drilled passages extending from inlets around the base of the stem to the inner end of the socket, providing a solid rod that has an inner end portion that will fit snugly in said socket, drilling a single passage lengthwise through said rod to form a nozzle, reaming the nozzle passage to taper it from said inner end of the rod substantially to its opposite end and to provide the large end of the passage with a diameter great enough to register with the inner ends of all of said head passages when said inner end is inserted in the socket, inserting in said socket the end of the nozzle provided with the large end of the tapered passage, and sealing the nozzle in the socket.
Claim 3
Dependent Claim
74 words
The method defined in claim 1, in which said socket is formed before said head passages are drilled, said head passages are drilled in positions to space their inner ends from the side wall of said socket, and said reaming enlarges said drilled rod passage until the wall thickness of the inner end of the nozzle is substantially equal to the width of the annular space around the inner end of the head passages.
