Brazing 22 Gauge Sheet Metal

In most cases an overlapped joint will be stronger and braze together easier than a gapped joint.

Brazing 22 gauge sheet metal.

If you burn through do not try and chase the hole you will just end up with a mess. Sheet metal gauge size chart gauge or gage sizes are numbers that indicate the thickness of a piece of sheet metal with a higher number referring to a thinner sheet. On the thin sheet metal a fairly fast travel stringer bead works well. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

Brazing is distinguished from welding because it uses an intermediary material usually a copper zinc alloy to join the two metal pieces rather. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. Brazing is also much easier then welding it s a lot like using a glue gun. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

Costs alot and takes some time. Brazing is a quick and inexpensive alternative to welding. I am not an expert or even close to being a competent welder but i just finished successfully mig welding a bunch of 22 gauge old and new sheetmetal. I only have a 115v lincoln promig 140 and ran 0 023 w c25 w machine b 5 voltage wfs.

Brazed metal can also be stronger then w. Shipping to alaska sucks. To weld mild steel choose an american welding society classification wire such as er70s 6 which has a weld puddle that wets out nicely. First of all if you are brazing steel that could mean you are using brass rod to join two pieces of steel together.

I have ordered the flange tool from hf about three weeks ago still do not have it. Gauge to thickness chart gauge stainless galvanized sheet steel aluminum fraction inches mm inches mm inches mm inches mm 30 0 0125 0 33 0 0157 0 40 0 0120 0 30 0 0100 0 25. Quick and easy brazing aluminum copper and nonferrous metals. When the material is 18 gauge and thicker you may be able to use a 030 inch wire.

I was originally running about 1 2 to 1inch of weld bead but getting warpage. But that was 20 22 gauge sheet. Im haveing some problems penetrateing enough to give a good hold without warping the work. Position the metal as desired.

Apply the brazing rod to the joint while continuing to heat the metal surfaces. If needed use clamps to secure the pieces in position. Learn more brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal. It s recommended to use a 023 or 024 inch wire for most light gauge sheet metal work.

The equipment in this project can be bought for as little as 30 dollars. I have gone down this road.
