Lubricant tube cracking brazing method
Recently, the county agricultural machinery repair center uses brazing to repair broken lubricating oil pipes. After many tests, the results are very good. The method is simple, economical and durable, and there are no traces on the surface. The welding repair method is as follows: Put the brass and cracked tubing as welding filler material on the furnace and heat until the tubing appears bright red. Take out and sprinkle a layer of borax on the cracked area to dissolve and remove the workpiece surface. Oxides and oils prevent surface oxidation and improve surface lubricity. When the borax melts, immediately apply the heated brass to the crack and apply it after cooling the tubing.
