The invention of the welding (also called thermite) pencil made it possible to work without welding equipment. This device is suitable for emergency situations, it is ideal for field conditions, but it is not able to completely replace the welding machine.
I successfully welded the steel tank with a thermite pencil when the weld seam on it parted and water began to flow out. I also tested the pencil on stainless steel, steel pipes and heat resistant plastics. This invention is suitable for work in rainy and windy weather, withstands low temperatures.
The welding stick works with the following materials:
- cast iron;
- copper and aluminum;
- brass and bronze;
- galvanized sheets;
- stainless or structural steel;
- heat-resistant plastic;
The principle of using a termite pencil
Initially, you need to carefully prepare the surface to be treated, remove all rust. Then it needs to be degreased, gasoline or some kind of solvent is suitable for these purposes.
After that, we remove the wrapper from the pencil, remove the cap by moving it to the other end (you must hold the pencil for this cap while working).
To prevent sparks from getting into your eyes, you need to wear glasses or a special mask. Hands should be protected with canvas gloves.
We set fire to the pencil (best of all with a lighter).
Pressing it against the material to be processed, carefully guide it along the line. At each point, you need to linger for a few seconds. In this case, the required volume of melt will enter the seam.
When working with thick metal, a pencil with a metal shaft should be used. When melted, it forms a weld. Note that there are different types of pencils sold for different metals.
The termite pencil also has its drawbacks: the material consumption is quite large, and the seam obtained in this way is not the most reliable and durable.
