aluminum flux core wire welding

1)The introduce of aluminum flux core wire welding
aluminum flux core wire welding is also called aluminum alloy brazing sheet. When brazing aluminum alloy using brazing under vacuum, vacuum brazing, flame brazing, high frequency brazing, etc., it is supplemented with aluminum brazing solvent. (Commonly known as aluminum solder) will work better together. When the aluminum alloy is brazed, the difference between the melting points of the brazing material and the weldment is very small, so it is more accurate in terms of temperature adjustment than other brazing requirements.
