In the current study, friction welding of two different steels, namely low alloy steel and austenitic stainless steel was done. For conducting welding, an in-house experimental set-up was designed and fabricated. The steels were friction welded by using various axial pressures at a uniform circular speed. Influence of axial pressure on the joint strength of the friction welded specimens such as tension, impact toughness, torsion strength and microhardness were evaluated. Moreover, the weldments were also tested for high temperature corrosion resistance. The corrosion testing of the welded joints was carried out in a molten salt environment of Na₂SO₄ + V₂O₅ 60% at 650°C. Weight change data were used to establish the kinetics of corrosion. Based upon this data, the weldments showing best corrosion resistance was identified. Subsequently to understand the composition of oxide scale, the specimen was evaluated using SEM/EDS and X-ray diffraction techniques.

在当前的研究中，完成了两种不同钢的摩擦焊接，即低合金钢和奥氏体不锈钢。为了进行焊接，设计并制造了一个内部实验装置。通过使用各种轴向压力以均匀的圆周速度进行摩擦焊接。评估了轴向压力对摩擦焊接试样的接头强度的影响，例如张力，冲击韧性，扭转强度和显微硬度。此外，还对焊件进行了耐高温腐蚀的测试。焊接接头的腐蚀测试是在Na ₂ SO ₄  + V ₂ O ₅的熔融盐环境中进行的650°C时为60％。重量变化数据用于建立腐蚀动力学。根据这些数据，可以确定显示出最佳耐腐蚀性的焊件。随后了解了氧化皮的成分，使用SEM / EDS和X射线衍射技术对样品进行了评估。
