Before watching I also thought it was going to be about welding tin foil or aluminum foil. Place them down in the bolt hole and after a few twists of the bolt it should start to become snug.

Examples of these heat-exchanger applications are Aluminium foil fins for evaporator and condenser coils in most residential automotive and commercial air conditioning units.
How to weld aluminium foil. After soaking in the water the ingot should be cool enough to touch. The weld to the left was made using a pull technique and the weld to the right using a push technique. The residual heat from the liquid solder should bond the foil together.
Ad High Performance Wide Range Structural Adhesives Bonding Plastic and Metal. This quick trick will have you welding thin aluminum foil in no time. Just like the the copper wire above aluminum foil can be used in the same fashion.
Get your welder ready to go. You can let the aluminum ingots air cool and then dump them out of the molds or use water to speed up the process. Get your two foil pieces together and make a clean cut along the edges so they line up nicely.
Tear a few pieces of aluminum foil off and fold them over. Pour some Loctite epoxy. You could also experiment with tipping the torch flame to pre heat the foil a bit.
Set the foil on the first steel coupon with about 116 to 18 15mm-3mm of foil sticking out. SUBSCRIBE for new videos every Monday and Friday. Position the wire brush on the aluminum surface where you want the weld and abrade the metal to remove the layer of oxide.
It is capable of producing sound welds in many alloys including those heat treatable alloys which are prone to hot cracking during fusion welding. For aluminium welding it is best to hold the torch nearly vertical and weld away from yourself push rather than pull. HttpsgooglFRdNssWhile it isnt the most practical application in the world it is sometimes fun to ch.
The technique of Friction Stir Welding is particularly suited to aluminium alloys. Brazing aluminum is a quick and inexpensive option for repairing leaks cracks or holes in aluminum and is often found in air-conditioning repairs. Aluminium Foil Fin Stock Finned Aluminium coils are used in a variety of heat exchange constructions where the basic function of the Aluminium fin is to efficiently conduct transfer heat.
Use aluminum foil. Its a great way to impress your unknowing friends and coworkersTIGWelding Fabricati. Place the other steel coupon on top and clamp the two pieces of foil tightly between your pieces of steel.
Youd have to adjust the drop height to get the temperature of the liquid soldier drop correct for bonding. This ensures that you weld into the shielding gas rather than away from it. I found that for joining the different sections two pieces of pencil lead the normal pencil kind held on top of the join about 05cm apart and discharging a 6800uF cap charged to 18V into the leads worked quite well to spot weld the pieces together.
But it should work. Pour the molten aluminum into steel molds. I have used aluminum tape to shield an electric guitar in order to drop the noise floor.
When compared to welding equipment aluminum brazing equipment is inexpensive portable and does not require high amounts of voltage. So I was really confused when the video got to the part about attaching the bag of water because I couldnt imagine what function it was going to serve in a tin foil welder. To water cool the aluminum take your tongs and place the ingot and mold into water for about 10 seconds.
Use an electric rotary tool with a fine steel wire brush attachment of less than 0004-inch wire diameter. You can get more information about welding and metalworking on our websit. This short video shows how you can actually weld together pieces of aluminum foil.
