| 摘 要： | 针对5mm厚度304不锈钢板,对超声钨极氩弧复合焊接的金属熔化行为机理进行了研究.与普通钨极氩弧焊对比分析表明,由于超声钨极氩弧焊复合焊接能大幅提高电弧力及电磁对流水平,使得熔池金属流动发生改变,提高了焊接熔深,增加了焊接深宽比,从而改善了普通钨极氩弧焊不适合焊接中等厚度板材的不足,拓宽了其使用范围,提高焊接生产效率.此外,结合试验与理论分析,进而对超声钨极氩弧焊提高焊接电弧力、增加焊接熔深的机理进行了研究.

| Abstract: | The mechanism of melting behavior of metal under ultrasonic-tungsten inert gas (U-TIG) welding was studied. The results indicate that U-TIG welding can significantly enhance the arc force and electromagnetic convection, change the metal flow behavior, and increase the penetration and the ratio of depth to width. This method extends the application range and improves production efficiency of ordinary TIG welding. Besides, the mechanism of arc force enhancing and penetration increasing were also presented in combination with experiment and theoretical analysis. |
