Abstract

Abstract In this paper, the effect of ultrasonic peening surface treatment on the mechanical properties of TIG butt weld joints of low-carbon steel (AISI 1020) was studied. A single V-angle (45°) was made on sheets of metal used then welded at constant parameters, namely: current, voltage. Wire filler ER70S-3 with argon was used to obtain many butt welding joints. Some of them were subjected to ultrasonic peening at one, two and three passes. The micro-hardness, microstructure, tensile and bending were tested. The results show increases in the tensile strength after the welding process. The test results showed improvements in the tensile strength of the weldments in comparison to the base metal. On the other hand, the tensile strength decreased with the ultrasonic process. Nevertheless, the tensile strength increased at a high number of ultrasonic passes. On the contrary, the ultrasonic process enhanced the bending strength compared to the base metal, whereas the weldments ability to bend deteriorated.

超声强化对低碳钢AISI 1020 TIG焊接接头力学性能的影响

摘要研究了超声波强化表面处理对低碳钢(AISI 1020) TIG对接焊缝力学性能的影响。一个单一的v角(45°)是在金属片上制成的，然后在恒定的参数下焊接，即:电流，电压。采用含氩气的焊丝填料ER70S-3进行对接焊接。其中一部分进行了一道、二道和三道超声强化。测试了合金的显微硬度、显微组织、拉伸和弯曲性能。结果表明，焊接后材料的抗拉强度有所提高。试验结果表明，与母材相比，焊缝的抗拉强度有所提高。另一方面，拉伸强度随超声处理而降低。然而，在高超声波次数下，拉伸强度增加。相反，与母材相比，超声处理提高了焊接件的弯曲强度，而焊接件的弯曲能力却变差了。
