Welding stainless steel with argon

What can distinguish features stainless steel welding? This material belongs to the well-being welded, but has its own specifics. Stainless steel comprises iron and the additional element in an amount of 10-30% (often chromium also using nickel, titanium, molybdenum). Among its physical properties include low thermal conductivity (approximately 1/3 of the standard carbon-rolled steel) and high linear expansion coefficient. Specificity of welding associated just with the presence in the composition of the alloying element, stainless steel imparts its properties. High temperatures lead to the formation of chromium carbide compounds, which negatively affects the properties of the steel, and leading to its brittleness. To prevent this, welding technology is constantly improving. Selection of the optimal welding process largely depends on the thickness of the sheet, the alloying element and the nature of the use of the finished product (outdoor or indoor, with temperature difference or not, whether large physical impact). Today, the most popular and widely used method is the argon-arc welding (TIG). It combines the features of an electric (arc) and gas (use of inert argon gas) welding. Among the great things about TIG – excellent quality of welds, the possibility of modulating the current parameters, welding in different planes.
