Brazing Thin Sheet Steel

Another method used to join pieces of metal together is brazing.

Brazing thin sheet steel.

Heat the joint where the two pieces of metal will meet. The intense heat of welding will likely burn through or at least warp the thin section. Brazing is distinguished from welding because it uses an intermediary material usually a copper zinc alloy to join the two metal pieces rather than melting the pieces themselves. Mig mag brazing of thin steel sheets.

In this technique a filler metal is melted and flowed into the joint where the connection needs to be made. Welding in a sequence that limits the amount of heat can help minimize distortion in thin material. Have you ever welded something so thin and worn out that all you do is blow holes in it. Steps use the wire brush or emery cloth to scuff the surface of the metal.

For instance when producing a 3 ft. And then stop to allow the weld to cool down before restarting again. Brazing is a similar method to soldering and welding and requires the metal to be melted so they can be joined. Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal.

On larger thin gauge material spread out several smaller welds over the joint. But you can further insure minimum resistance by using a close joint clearance to keep the layer of filler metal as thin as possible. Did you want to learn how to work around that and deliver a solid re. The filler material flows into any and all microscopic crevices in the metal and pulls the pieces together similar to a permanent velcro.

Sheet metal bonded to 0 5 in. Then clean the surfaces using soapy water or a. There are many materials that can be used to make the filler metal. Brazing is done at lower temperatures without melting the base metals.

In most cases an overlapped joint will be stronger and braze together easier than a. Weld in the vertical down position weld 6 in. Mig mag brazing of zinc coated and stainless steel sheet. Position the metal as desired.

A silver brazing filler metal by virtue of its silver content has very little tendency to increase electrical resistance across a properly brazed joint.
