Soldering is a great way to create permanent joints in many different metal types. Not only does it work well for family repairs, but it can also be used in small scale manufacturing applications. Soldering works by using heat to liquefy solder, which is an alloy of different metals, and applying the molten metal mixture to two separate pieces before it cools.
The metals in the solder alloy melt at lower temperatures than the other metal pieces being soldered together, so they are liquid while the surrounding pieces remain solid. What makes stainless steel cookware so popular is its durability and corrosion resistant quality.
Today we are going to take a look on how to solder stainless steel cookware.
How To Solder Stainless Steel Cookware- The Steps
Step 1- Cleaning AndPrepping
The first step is to clean and prep your work area. You will want to make sure that you have adequate ventilation as well as a fire-resistant surface such as concrete or cement. Make sure even your floor is protected, as the solder paste you use will get on the floor, and when it is mixed with flux it can be very slippery.
You should also make sure that you have all of your tools readily available; things like pliers, Allen wrenches (if using a propane torch) and screw drivers (if removing any rings). Also make sure you have your stainless-steel cookware pieces ready.
Step 2- Heat TheCookware Pieces
The next step is to heat up the two separate pieces that you will be soldering together. You can do this by either placing them over hot coals (not recommended), or with a propane torch. If using a propane torch, make sure it has adequate ventilation as it can produce a lot of fumes from the flux.
Step 3- Mix TheFlux Paste
Once your cookware pieces are heated, mix your solder paste according to package instructions and put it on one side only. The solder paste should not be applied directly onto your cookware as high heat could cause the flux inside to burn off. Instead, you want to use the flux paste to create a small puddle on your work surface.
Step 4- Apply Solder Paste
Put enough solder paste on the cookware piece that will receive the metal you are trying to solder, and then take some pliers or wire cutters and push it into the solder puddle (the solder should not just stick to your pliers, you need to push it into the solder puddle).
Step 5- Solder On
Once you have done this, take the cookware piece that has flux paste on its side and place it down onto the cookware piece with the solder paste/wire sticking up; make sure everything is lined up properly.
Now all you need to do is wait. The solder should stay liquid for around 3 minutes, so this process will not be rushed. Once the solder hardens/dries you are done!
Step 6- Finishing
Once your solder joint has hardened, you can begin filing down any excess solder with a metal file or grinder. Alternatively, you can sand it down with sandpaper.
After this, your solder joint should be finished! You could also opt to use paint or sand paper over the solder paste to make any bumps in the surface less obvious.
Step 7- Clean Up
Finally, when you are all done soldering, clean up your work area and dispose of your flux paste, as it is toxic.
Soldering Stainless Steel Cookware- Cautions
Stainless steel cookware can be soldered using a gas-powered torch or an electric heat gun. Before attempting to solder stainless steel cookware, it is wise to read up on the process thoroughly. Soldering stainless steel can be dangerous if not done correctly.
With proper safety precautions in place, soldering metal pieces together is an easy task that will leave you with a strong bond between pieces of metal. Stainless steel cookware pieces are made from various types of metals including steel, nickel and chromium. The cautions when soldering stainless steel cookware are given below-
1. Make sure to use your propane torch in a well-ventilated area; there is some risk of combustion with propane torches, so make sure this process is done very carefully.
2. You will want to wear protective gloves while using the solder paste and while cleaning up afterwards, as it can get very hot (over 100 degrees Celsius) and can burn your skin.
3. Make sure you have all the required tools for this process before starting, as there is risk of injury with propane torches and solder paste.
4. After applying solder to cookware pieces it is best to let them sit for 3 minutes unchanged before moving or putting any pressure on the pieces being soldered. If this is not possible, apply pressure as least as you can and wait at least one minute before applying additional force.
5. Always have a fire extinguisher readily available during this process.
6. Be careful while using wire cutters to push solder paste/wire into the solder puddle on your work surface, as the solder paste can be very hot and cause burns.
7. Make sure to pay attention to what you are doing; do not let distractions take your attention away from the soldering process.
8. Finally, if solder is applied directly onto clothes, they should be rinsed immediately with cold water (if done shortly after applying) or placed in cold water with salt and bicarbonate. If this is not done quickly enough, the clothes could be ruined as solder has a melting point of over 600 degrees Celsius.
Soldering is a great way to create permanent joints in many different types of metal. In this article we will look at how to solder stainless steel cookware using a propane torch and solder paste/wire.
