Abstract
A method of attaching a casted metal part and a metal hose line includes: providing a cast metal part having a cylindrical portion; providing a metal hose line; heating the metal hose line to a temperature of between 500 and 900 degrees Fahrenheit; positioning the inner diameter of the metal hose line over the outer diameter of the cylindrical portion; allowing the metal hose line to cool to reduce the gap between the inner diameter of the metal hose line and the outer diameter of the cast metal part; and forming a first weld along an outer circumference of the metal hose line, wherein the width of the first weld at the connection between the hose line and cast metal part is 50% or less than the metal hose wall thickness.

An attachment connection comprising:
- a first metal part having a generally cylindrical portion, wherein the first metal part is a casted metal part;
- a second metal part having a generally cylindrical portion positioned about the generally cylindrical portion of the first metal part, wherein the second metal part is a hose line having a wall thickness;
- one or more weld connections between the first metal part and the second metal part, wherein the weld connections each comprise a weld seam having a thickness at the connection between the first and second metal parts that is less than 50% of the wall thickness of the second metal part.
A method of attaching a casted metal part having a generally cylindrical portion and a metal hose line having a wall thickness, the method comprising:
- providing a cast metal part having a cylindrical portion having an outer diameter;
- providing a metal hose line having an inner diameter and a wall thickness;
- heating the metal hose line to a temperature of between 500 and 900 degrees Fahrenheit;
- positioning the inner diameter of the metal hose line over the outer diameter of the cylindrical portion;
- allowing the metal hose line to cool to reduce the gap between the inner diameter of the metal hose line and the outer diameter of the cast metal part;
- forming a first weld along an outer circumference of the metal hose line, wherein the width of the first weld at the connection between the hose line and cast metal part is 50% or less than the metal hose wall thickness.
