Brazing Thin Sheet Steel

Heat the joint where the two pieces of metal will meet.

Brazing thin sheet steel.

Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal. 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. In this technique a filler metal is melted and flowed into the joint where the connection needs to be made. For instance brazing is the better option on a t joint with 0 005 in.

In most cases an overlapped joint will be stronger and braze together easier than a. Brazing is done at lower temperatures without melting the base metals. There are many materials that can be used to make the filler metal. For instance when producing a 3 ft.

Mig mag brazing of zinc coated and stainless steel sheet. 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. On larger thin gauge material spread out several smaller welds over the joint.

Another method used to join pieces of metal together is brazing. A silver brazing filler metal by virtue of its silver content has very little tendency to increase electrical resistance across a properly brazed 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. Position the metal as desired.

Sheet metal bonded to 0 5 in. And then stop to allow the weld to cool down before restarting again. Weld in the vertical down position weld 6 in. 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.

Brazing is a similar method to soldering and welding and requires the metal to be melted so they can be joined. Welding in a sequence that limits the amount of heat can help minimize distortion in thin material. The filler material flows into any and all microscopic crevices in the metal and pulls the pieces together similar to a permanent velcro. The intense heat of welding will likely burn through or at least warp the thin section.

Have you ever welded something so thin and worn out that all you do is blow holes in it.
