Brazing sheet steel. Use a torch that produces a high intensity flame. The brazing rod should be melted by the heat of the metal pieces being joined not by direct contact with the flame of the torch. Brazing requires less energy than welding and can be used to join dissimilar metals. It shows how the tensile strength of the brazed joint varies with the amount of clearance between the parts being joined.

Note that the strongest joint 135 000 psi 930 8 mpa is achieved when the joint clearance is 0015 038mm. For over 25 years lynch metals has been north america s largest stocking distributor of aluminum brazing sheet stainless steel other metal alloys. With proper flux provided in the joint brazing steel can be done with mechanized torch setup or within induction coils depending on requirements and availability of equipment. Mix a small amount of flux with water to form a paste.

Wipe the areas on the metal pieces that will be joined with the emery cloth so the surfaces are free from dust and grease. Pure copper and copper zinc filler metals are used for brazing steel and other materials. Apply this paste to the areas on the metal pieces that will be joined using the brush. A table listing copper base alloys can be found in a commercial publication.
