无损检测用焊缝试板裂纹缺陷制备技术研究
Research on manufacturing technology of weld test plate with crack for NDT training
摘要
Abstract
Aiming at the problem of preparation of crack defects in weld test plates for NDT training,this paper carried out research on different material filling welding technology.Through the crack mechanism analysis,cast iron,copper,high-strength steel and tungsten electrode were used as dissimilar filling materials to weld carbon steel welds and prepare internal and surface welding cracks.Ultrasonic,magnetic particle,penetration and other NDT methods were used to compare and verify the defects obtained after welding of four kinds of materials.The results show that copper as filling material can lead to more ideal welding cracks,and it shows better results under various NDT verification.关键词
