Argon
The element used in an oxy-acetylene flame is carbon. Acetylene gas acts as the fuel, while oxygen is used as the oxidizer in the flame. The high temperature resulting from the combustion of acetylene and oxygen produces a clean and precise flame that is commonly used in cutting and welding applications.
Lead is a pure element - there is no silver in it.
Air (clean or dirty) is a mixture, as it contains several different gases.
Mineral-based fluxes are commonly used in welding to facilitate the joining of metals by removing oxides and impurities from the surfaces, promoting wetting, and preventing oxidation during the welding process. These fluxes are composed of mineral compounds such as borax, fluoride, and chloride, which lower the melting point of the oxide layers and help to create a clean and strong weld. Different types of mineral-based fluxes are used based on the specific requirements of the welding application, such as soldering, brazing, or welding different metals.
Chlorine is commonly used as an element to clean and disinfect water in pools, as well as surfaces in households and healthcare settings. Its oxidizing properties help to kill bacteria and viruses.
It is generally called a flux or cleansing agent. Sometimes contained in electrode coatings and found in powdered form to use in the Oxy-fuel welding process. Primary ingredient is Borax ( yah same as in some hand cleaners). Often mixed with water to form a paste that can be applied by a brush to both the welding/brazing rod and also the base metal.
Yes. However, there are paints designed to be compatible with welding as they are designed to protect the surface of the plate from corrosion while in storage. In every code or specification, it is specifically stated that welding should be done on clean metal. Welding over paint is discouraged.
To achieve pretty welds in your welding projects, it is important to ensure that your welding equipment is in good condition and that you have the proper settings for the type of metal you are working with. Additionally, practice proper welding techniques such as maintaining a steady hand, using the correct welding speed, and ensuring proper penetration and fusion of the metal. Clean the metal surfaces before welding and use the appropriate filler material for a clean and strong weld. Regular practice and attention to detail will help you achieve aesthetically pleasing welds in your projects.

TIG welding is a method of welding. A tungsten electrode heats up the metal that is to be welded while a gas, such as argon, protects the weld from being contaminated. This method allows for clean, accurate welds. It can also be used on more metals than any other welding process.
It depends on what type of contaminents are present. Usually, a NEW stainless steel wire brush will do the trick. If there is a large build-up of contaminants, you may consider using a grinding disc or flap disc on an angle grinder, again being sure that they are NEW and clean. Also, there are chemical solvent cleaners available for the removal of storage oil on aluminium, I can't think of the names, but it should be available at your nearest welding supplier.
I was taught oxy/acetylene welding first, then stick. TIG welding is just like oxy/acetylene except much easier (less variables and a foot control to make minor corrections or even pulse the weld) I would recommend you learn both. TIG welding for precise/clean welding. Stick for some larger, perhaps special welding (hard facing tools - bigger pieces of steel).
When welding on AC on a TIG welder you have to option to adjust how your arc passes from your torch to your metal and vice versa. This allows you to clawed your puddle clean of contaminants or burn your weld deeper while welding. When set on balanced, the arc equally passes in both directions.
Argon is a noble gas commonly used in welding as a shielding gas to protect the molten metal from reacting with the surrounding air. It helps prevent oxidation and promotes a clean, strong weld by maintaining a stable inert atmosphere around the welding area.
Iodine is a chemical, an element with the atomic number 53, one of the halogen series. It is used medically in the prevention of goitre and formerly to clean wounds. It is purple when in gas form.
Argon welding commonly uses materials such as steel, stainless steel, aluminum, and titanium. These materials are compatible with the inert shielding gas, argon, to protect the weld pool from atmospheric contaminants during the welding process, ensuring clean and strong welds.
The term flux means to clean. Not all welding processes use a flux. Stick welding electrodes contain fluxing agents. MIG hard wire doesn't but flux-cored MIG wire does. TIG does not as the rods are bare. Most brazing applications require flux. Gas welding usually doesn't except for certain metals.
