Abstract
Welding, soldering and brazing and wire filler metals having a metallic sheath enclosing a core wire and, preferably, filler powder materials. The diameter of the composite wire is reduced by drawing, rolling or swaging. The composite wire is easier for filler metal manufacturers to make and can have better operating characteristics leading to improved bead appearance and joint quality.
Claims19
A method of making a cored wire filler metal comprising the steps of providing a core wire having a chemistry and then deforming a metal strip of a width having a different chemistry into a sheath enclosing the core wire, the sheath having a circumference of less than about 78% of the width of the metal strip.
