PRODUCT INFORMATION Category: Copper & Copper Alloys Alloy: WWLFB Bare Class: LBF Bare (Low Fuming Bronze) Description: Designed for repair and fabrication applications on steel, copper, copper alloys, nickel, and nickel alloys. Recommended procedure: Clean all areas to be joined or built-up thoroughly. Paint weld area with Welco 600 bronze brazing flux. Using a neutral flame, heat the part until the flux liquefies. The flux can also be applied directly to the rod, by heating the rod and dipping into the powered flux. Add a drop of the alloy and flow it out using the torch flame. If a large area is to be surfaced or a number of passes are required to restore the part to the original size, Nickel Silver flux coated rods should be used. There is no need to remove the flux between passes. The torch should be held at a low angle to prevent excessive heat build-up in the part. When working on cast iron, bonding qualities can be improved by first searing the surface with a strong oxidizing flame.
