Rapid welding of stainless steel wires using ultra-high frequency induction heating

In this study, JIS SUS202 stainless steel wires are rapidly welded by induction heating using a current at a frequency of 2 MHz. The effects of the heating parameters on the mechanical properties and microstructures of the joint are investigated. After induction welding, the main structures in the joint of the 202 stainless steel wires are austenite and ferrite. The amount of ferrite increases by increasing the heating temperature or heating time. Moreover, the tensile strength of the joint is superior for a higher welding temperature.
