HIGH FREQUENCY INDUCTION WELDING OF HIGH SILICON STEEL TUBES

HIGH FREQUENCY INDUCTION WELDING OF HIGH SILICON STEEL TUBES

High-Si steel is a low cost alternative for the fabrication of tubular structures resistant to atmospheric corrosion.However, the literature has often pointed out that steels presenting a higher Si content and/or a lower Mn/Si ratio Pillows have higher susceptibility to defects at the weld bond line during HFIW (High Frequency Induction Welding) pr
