特高压钢管塔对接环焊缝的超声波检测，依据 GB/T 11345和Q/GDW 707进行检测。由于钢管塔构件和焊缝的错边、余高和焊缝宽度等情况，易导致检测误判。对钢管塔法兰-钢管对接环焊缝超声波检测若干影响因素进行了分析，提出了识别和判定方法，可以实现对钢管塔对接环焊缝焊接质量的有效控制。
特高壓鋼管塔對接環銲縫的超聲波檢測，依據 GB/T 11345和Q/GDW 707進行檢測。由于鋼管塔構件和銲縫的錯邊、餘高和銲縫寬度等情況，易導緻檢測誤判。對鋼管塔法蘭-鋼管對接環銲縫超聲波檢測若榦影響因素進行瞭分析，提齣瞭識彆和判定方法，可以實現對鋼管塔對接環銲縫銲接質量的有效控製。

According to the criteria of GB/T 11345 and Q/GDW 707, ultrasonic testing was applied into butt circumferential weld of UHV steel tower. Weld offset,reinforcement,weld width of steel tower may lead to misjudgments of ultrasonic testing. In this paper, aiming to the analysis on the influence factors of steel tower flange and butt circumferential weld on exact implementation of ultrasonic testing, the methods of distinguish and judgment of ultrasonic testing were put forward. It can realize efficient controlling of welding quality for steel tower butt circumferential weld.
