Oxy-Acetylene Welding of Aluminum While aluminum has a melting point less than half that of steel, its conductivity is over three times as great, so we use a tip about the same size for this metal as we do for steel, and because of this conductivity, we should realize that the effects of expansion and contraction must be particularly guarded

Oxy-Acetylene Welding of Copper Copper conducts heat more rapidly than any other commercial metal. It will oxidize very easily and this oxidation is not easily apparent to the operator, but the weld becomes very brittle. The melting point is under that of steel and iron, yet because of its high conductivity a larger tip for the same size material is

In many instances, aluminum is joined with the conventional equipment and techniques used with other metals. However, specialized equipment or techniques may sometimes be required. The alloy, joint configuration, strength required, appearance, and cost are factors dictating the choice of process. Each process has certain advantages and

Aluminum Brazing a. Aluminum Brazing. Many aluminum alloys can be brazed. Aluminum brazing alloys are used to provide an all-aluminum structure with excellent corrosion resistance and good strength and appearance. The melting point of the brazing filler metal is relatively close to that of the material being joined. However, the base metal should not be melted; as a result, close
