Alternative To Welding Sheet Metal

Brazing is a quick and inexpensive alternative to welding.

Alternative to welding sheet metal.

Butt weld vs lap weld. Understandable who would want to wear a welding mask all day. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. Brazing is also much easier then welding it s a lot like using a glue gun.

For many decades welding was considered the only way to ensure joint integrity in demanding load bearing or high vibration structures. Today there is a fastener alternative to welding. An overlapping joint. Because it will have you a lot more control over the whole process and it is more forgiving in case you do anything wrong.

These two piece fasteners are part bolt and part blind rivet. This is why production body shops swear by them. The fifth and probably most common alternative to welding besides riveting is using bolts and nuts or just bolts if the base metal is threaded. Lap welds are used when quick results are needed.

Don t attempt to weld thin materials like sheet metal with flux cored wires which put more heat into the base metal. A lap weld is much easier than a butt weld but doesn t seal correctly and will promote moisture from the back side. The answer to reducing your welding hours lies in a special product called methyl methacrylate adhesive mma mma adhesives have two liquid components that require mixing before application and offer an extraordinary bond to surfaces that require almost no preparation. The equipment in this project can be bought for as little as 30 dollars.

The majority of the sheet metal welding i ve done was with a 90 amp 110 volt welder. Forget the larger 1 8 inch tungsten electrode and use a smaller one. Brazed metal can also be stronger then w. Sheet metal can be joined using spot welding where the metal is held between copper electrodes.

So companies manufacturing heavy duty equipment or fabricating large metal structures only welded joints. Like riveting using bolts is an irreplaceable technique of joining two pieces of metal without welding. Like with welding bolts are used everywhere from cars to planes to bicycles. Quick and easy brazing aluminum copper and nonferrous metals.

This technique is fine for thin metal but is not suitable for thicker metal or tubular steel. Tig welding sheet metal.
