The components of construction steel structure nee-d to welding production to complete and the quality of the wel-d joint is the main factor to affect the components quality. Ult-rasonic flow detection is non-destructive testing technology w-hich is widely used, mainly applied to detect internal defects s-teel welds. This article discusses this issue in order to ensure t-he quality of steel construction.
