Brazing Thin Sheet Steel

The filler material flows into any and all microscopic crevices in the metal and pulls the pieces together similar to a permanent velcro.

Brazing thin sheet steel.

Another method used to join pieces of metal together is brazing. Did you want to learn how to work around that and deliver a solid re. Brazing is a similar method to soldering and welding and requires the metal to be melted so they can be joined. Brazing is done at lower temperatures without melting the base metals.

Heat the joint where the two pieces of metal will meet. But you can further insure minimum resistance by using a close joint clearance to keep the layer of filler metal as thin as possible. For instance brazing is the better option on a t joint with 0 005 in. And then stop to allow the weld to cool down before restarting again.

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. A silver brazing filler metal by virtue of its silver content has very little tendency to increase electrical resistance across a properly brazed joint. Steps use the wire brush or emery cloth to scuff the surface of the metal.

Position the metal as desired. On larger thin gauge material spread out several smaller welds over the joint. 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. Because of this you don t need the base metals to be similar so it s possible to tig braze copper to stainless steel as an example. Sheet metal bonded to 0 5 in. A process optimisation for coated c mn high strength steel and a parameter investigation of c mn high strength steel stainless steel and aluminium alloys.

Then clean the surfaces using soapy water or a. Mig mag brazing of zinc coated and stainless steel sheet. In most cases an overlapped joint will be stronger and braze together easier than a. Weld in the vertical down position weld 6 in.
