Welding Sheet Metal Heat Sink

Through fixtures and heat sinks we ensure your design tolerances are met and the aesthetic of your finished project isn t sacrificed on the altars.

Welding sheet metal heat sink. Sheet metal welding seventy years working with metal yields a deep understanding of the complexities of welding sheet metal assemblies where heat and distortion lay waiting to hijack your project. The majority of the sheet metal welding i ve done was with a 90 amp 110 volt welder. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. Don t attempt to weld thin materials like sheet metal with flux cored wires which put more heat into the base metal.

Another alternative is to surround the area you re welding with an anti heat compound that will block the heat from spreading to the rest of the panel and potentially reduce warping in the panel. If you grasp that fact and utilize it using copper for heat sinks is one of the best tig welding tips ever for welding stainless steel sheet metal. Forget the larger 1 8 inch tungsten electrode and use a smaller one. Tig welding sheet metal.

That s the kind of protection cold shield provides. The part in my fingers never went above about 85 degrees f. The same way your internal combustion engine computer cpu and home heating systems do with an efficient heat transfer medium a k a heat sink. Copper is almost magical when it comes to welding stainless steel.

Based on this definition anything from a rectangular sheet of metal to a complex finned copper or aluminum extrusion can be used as a heat sink. Stop welding heat damage this is the kind of product that you have to try to believe how well it works. We held onto a small metal panel while a torch heated the metal almost white hot. Mig welding is the preferred method for most automotive bodywork and since sheet metal is the thinnest of metals a large expensive mig unit is usually not required.

A heat sink is a part that conducts heat from a heat generating component to a larger surface area to dissipate the heat to the surroundings thus reducing the temperature of the component. Our copper weld backers help to keep a welds from blowing through the metal and also act as a heat sink.
