Welding is a fundamental industrial metal fabrication process. The process involves combining heat, pressure, and filler metals to join separate pieces of metal. The process allows contractors to fabricate metal products and to join parts such as the plumbing system, heat exchangers, and other crucial repair processes. The principle of welding sounds simple, but it can get massive complications. It is advisable to let professionals handle your projects because they determine the best welding process to employ. Here are the most popular welding services.
Shielded Metal Arc Welding
Shielded metal arc welding is a conventional joinery method that has been in use for decades. It comprises an electrode that looks like a stick. The electrode transfers electric current into the base of the metal and helps join the metals together. The electrode typically has a flux coating around it. During the process, both components melt. The flux coating creates a shield that protects the surface from contamination.
The Gas Tungsten Metal Welding
Gas tungsten metal welding is another process that is quite common in fabrication. It involves the use of tungsten, which is an inert gas. The gas tungsten welding is a little different from the other options in the market in that it needs an external source of gas to shield the metal and prevent contamination. The other difference is that the electrode in the gas tungsten welding method does not melt. Tungsten has an extremely high melting point and is close to impossible to melt under these conditions. However, the process is a little more complex than others. It is advisable only to allow someone with several years of experience to handle the process for you.
The Submerged Arc Welding
Submerged arc welding is different from the other alternatives because of mechanisation. Engineers usually plan the welding project before starting. The plans involve setting up the entire welding process and ensuring everything is precise before running the program. The method involves the use of a granular flux to cover the whole surface getting welded. Therefore, the process does not allow you to see the actual process of the metallic parts fusing. Instead, they set up the system and deliver the joined metal. The method is excellent for projects that do not have any space for human error.
These are some of the common processes followed when welding metal for various fabrication projects. It is advisable to look for a competent contractor to handle your welding project for the best results.
