Soldering refers to the process of joining identical or even dissimilar metals together with the use of filler. The filler metals usually contain a base of copper and silver, nickel, zinc or phosphorus. This process is similar to welding, but the key difference is that soldering does not melt the base metal because it uses lower temperatures (900 to 2200 degrees Fahrenheit). This makes soldering the preferred method for joining dissimilar metals. When soldering stainless steel or other materials, the results are strong and in many cases will be stronger than the base metals that have been bonded together. Companies that provide heat treatment services will help anneal and solder the steel. If you are interested in Stainless Steel Benchtops in Melbourne, check out the guys at Archer Metals.
After such a company is hired, here are the steps that this company will take on when soldering steel:
Prepare a work surface: remove flammable objects from the work surface and the surrounding area. Clean the metal parts to remove chemical residues, thoroughly dry them, and then clean the stainless steel parts.
Application Flux: Flux is a chemical cleaning agent with more than one function at a time and is used for joining metals and extraction metallurgy. Flux has two roles in soldering stainless steel; it dissolves oxides on the surface of the metal and acts as an oxygen barrier to reduce oxidation.
Make sure that the work surface has a brass plate to absorb excess heat: the company that provides heat treatment services will already be equipped with the necessary brass plate.
Start heating metals: the piece should be placed on a brass plate, and then heated with a torch. The two parts will continue to heat until the stainless steel surface melts.
Click “Parts Together”: this will prepare the parts for the process of adding the filler.
Prepare a working area for the use of filler: clean the work area, and then use a flux for cleaning stainless steel.
Heat the metal on a brass plate: reheat the steel so that it is not enough to bond with the filler. The best way to determine if it is enough is to touch the filler to the stainless steel. Steel is hot enough if the metal filler melts on contact.
Combine the metals: when the stainless steel is warm enough, attach it to the filler to get the connection.
Companies that provide heat treatment services may have specialized tools or resources that facilitate the implementation of this process. When soldering steel, special care must be taken to prevent oxidation. Also, the heat cycle should be well controlled, the cooling cycle must be controlled and strong, and the atmosphere must be reliable. Stainless steel will have maximum corrosion resistance when soldering or annealing is performed by a competent organization providing heat treatment services. Organizations that need help in soldering steel should find a company with many years of experience that can guarantee consistent brightness and timely delivery.
