Abstract
A wire (10) for use in a brazing or soldering operation has an elongated body (12) of a metallic material. The elongated body (12) has an outer surface (18). A channel (14) is formed along a length of the body. The channel (14) has an opening (A1). A flux solution (22) is deposited within the channel (14) and along the length of the body. The flux solution (22) covers a portion of the outer surface (18). A portion of the flux solution (22) is exposed through the opening (A1) in the channel (14).
Claims21
1-20. (canceled)
A method of forming a brazing wire comprising:
- forming a first longitudinal channel in an elongated length of a brazing metal;
- applying a first flux solution to the elongated length of brazing metal;
- wiping a portion of the flux solution from the elongated length of brazing metal;
- and,
- solidifying a remaining portion of the flux solution to the elongated length of brazing metal to form the brazing wire.
The method of claim 27 wherein the step of passing the elongated length of brazing metal through a wiper having a shaped opening as it exits the holding chamber comprises:
- removing all of the first flux solution from around the length of brazing wire except for the channel.
A method for forming a brazing ring comprising:
- forming a first longitudinal channel in an elongated length of a brazing metal;
- applying a first flux solution to the elongated length of brazing metal;
- solidifying the first flux solution to the elongated length of brazing metal to form the brazing wire;
- and,
- bending the brazing wire and solidified first flux solution into ring shape having the first flux solution along an inner circumference of the ring shape and compressing the solidified first flux solution in the first longitudinal channel.
