What is Short Circuit Transfer Welding?
Short Circuit Transfer Welding (SCTW) is a welding process used by welders to join metal components. It is a variation of the Gas Metal Arc Welding (GMAW) process, also known as MIG welding, and is often used for light to medium-gauge steel and aluminum.
The SCTW process is characterized by a high-speed, short-circuit metal transfer with a low-voltage, high-amperage welding power source. In this process, the welding arc is established between the metal components and the wire electrode. The arc is then sustained by a series of short-circuit transfers, which create a series of overlapping weld beads.
The SCTW process offers several advantages over traditional arc welding processes. For example, it allows for faster welding speeds, better weld bead control, and improved penetration. In addition, the process also produces high-quality welds with a smooth finish and minimal spatter. As a result, it is an ideal welding process for many welding applications.
According to the American Welding Society, SCTW is used in a variety of industries, including automotive, aerospace, and construction. In addition, the process is widely used in the fabrication and repair of sheet metal and thin-gauge components. On average, welders can complete SCTW projects in less than half the time of traditional arc welding processes.
.A Brief History of Short Circuit Transfer Welding
Short Circuit Transfer Welding (SCTW) is a type of arc welding process that has been used in the construction of welders since the early 1900s. It was first developed in Europe, specifically Germany, in the late 1920s and early 1930s and became widely used in the 1940s.
The term “short circuit transfer welding” was first coined by German welding engineer Dr. Hans Goldschmidt in 1931. The process involves the use of a wire electrode and a direct current welding power source to create an electric arc, which is then used to transfer metal from the electrode to the base metal. This process is known for providing a high quality weld with low distortion and minimal spatter.
Since its introduction, SCTW has been widely used in the construction of welders as it is a highly efficient and cost-effective process. It is also used in many other industries and applications, including fabrication, automotive, aerospace, and shipbuilding.
Today, Short Circuit Transfer Welding remains a popular choice for many welders and is used to create strong and reliable welds in a variety of materials.
