Stainless steel sheet, as one kind of energysaving materials with superior performance, has been widely applied to national production, and has broad application prospects. Based on the importance of stainless steel sheet, studying the welding process is of great significance to promote the development of stainless steel sheet industry. In this paper, the effect of welding process on weld geometry and joint properties of stainless steel sheets are reviewed. Weld geometry of laser welding joint is better than that of arc welding joint for stainless steel sheet welding. Good weld geometry can be obtained through appropriate shielding gas method and waveform control. High energy beam welding and friction stir welding can optimize the joint mechanical properties due to grain refinement. The corrosion sensitivity of joint by welding process of low heat input falls off. The shielding gas flow rate and external magnetic field have strong positive effect on corrosion resistance.
