Welding is a process for joining similar metals. Welding joins metals by melting and fusing the base metals being joined and the filler metal applied. Welding employs pinpointed, localized heat input. Most welding involves ferrous-based metals such as steel and stainless steel. Welding covers a temperature range of 1500? F – 3000? F. Weld joints are usually stronger than, or as strong as, the base metals being joined. Typically, welding is used for forging, blacksmithing, oil pipelines, and food equipment applications.
