You will need
- - solder;
- - copper plate;
- - a metal file or sandpaper;
- - gasoline, flux or "soldering acid";
- - soldering iron.
If the hole is small, take to braze a piece of aluminum wire or tin solder. For the large hole, find a piece of copper plate and cut the patch to a size slightly larger than the hole.
Before you start to solder the pan, clean the bottom surface of needle files, a file or sandpaper to the bare metal so that there is raids, a copper plate is also buff to a Shine. Degrease the surface with gasoline or other solvent, then apply the flux with a brush (flux necessary for complete cleansing of grease and removal of oxide films from metal). Instead of the flux, you can use "liquid solder" or "soldering acid".
Take a soldering iron, heat it and dip it into the powder rosin or Sal ammoniac (to cleanse from the metal oxides). If there is light smoke, soldering iron ready to go. Touch the tool to the solder and keep it there until it is covered completely brilliant film. Then grab some solder tip and transfer it to the soldering. Smooth over the surface of the bottom of the pan around the holes (saludito the place of junction).
Take the solder tip of the iron and transfer is necessary for sturdy mounting in place of the spikes. Small holes can be filled completely with the solder. For mounting plate, apply solder around the holes, flatten the top and apply the patch. To plate well seized and consolidated, an additional soldering iron heat the entire surface of the patch.
After the solder has cooled, wipe it damp cloth and smooth off with a file or sandpaper.
If you need to solder aluminum pan, be aware that it is somewhat more complicated as aluminium is hard to solder. Below the surface has formed, the oxide film immediately after Stripping the place of junction, immediately pour pre-melted rosin. Soldering lead is a very powerful soldering iron (at least 100 watts). Use a solder of 80% or 95% tin, 20% and 5% of bismuth respectively. Flux pick from, stearin or paraffin. If you fulfill all these conditions, it's easy to solder a pot made of aluminum.
Advice 2 : How to clean aluminum pan
Even the most careful Housewives happen to troubles such as your dish. One has only to turn away in an instant, preparing food manages to turn into embers and, in addition, firmly stick to the bottom and the walls of the vessels. Especially easy to burn food in aluminum pots, so that the elimination of the consequences may be puzzling to any housewife. However, it is not necessary to put an end to much of the baked dish. Clean aluminum pan , you can use several available tools.
You will need
- - sponge for washing dishes;
- - plastic brush;
- - a jar of silica glue;
- - Laundry soap;
- - large capacity for boiling.
Place of burnt aluminum pans with a spoon remains preparing food. Do not attempt to scrape the pan for removing burnt -, it will only scratch the coating and will damage aluminum cookware.
In simple cases, burning food, use of proven and available at any time to the mistress of the way. Pour into aluminum pan so much water that it reached the end of the burnt lines on the walls of the cookware. If you only burnt the bottom, pour water at 1-1.5 cm above the bottom of the pan. Put in the capacity of citric acid or baking soda at the rate of 1 teaspoon to 1 liter of water. Close the pot lid, put on fire and boil for 10-15 minutes.
When burning the pan more than usual boiling one soda may not help the dishes. In this case, supply the store with a jar of silicate glue. Pour into the pan liter of water, pour into it a tablespoon of baking soda, add same amount of silicate glue. Stir the resulting solution and close the pan with a lid. Boil on the fire this mixture at least 30 minutes. Then, turn off the heat and leave the pan with solution to cool. Then pour the cooled mass from the dish and gently RUB its sides and bottom with a plastic brush.
If contamination of the pan spread on its exterior walls, try to clean the dishes completely, and boiling it in a bigger pot. Dirty dishes should be able to slide in the container. Fill baked dishes in a larger container with water so that the water was at the level 1-1.5 cm above the cleaned pan. Grate in a container of soap and add to the same transparent silica glue. In one liter of water, the ratio in grams of soap and glue is 20:10. Boil the resulting mass for 2-3 minutes and leave it to cool down. After that, wash clean aluminum pan under running water with a soft sponge.
Do not use for cleaning aluminum pots of various corrosive acids and abrasive substances. From them damaged the surface of the aluminum, and the metal particles then fall into the food.
