【摘要】：特高壓輸電線路鋼管鐵塔是架空高壓輸電線路的重要組成部分,其焊接質(zhì)量已成為輸電線路整體質(zhì)量的重要環(huán)節(jié)。由于管徑273 mm,壁厚≤6.0 mm的塔材的管徑和壁厚較小,對(duì)其與鍛造帶頸法蘭的焊接提出了新的難點(diǎn)。針對(duì)該焊接難點(diǎn),制定了手工V型坡口管對(duì)接水平轉(zhuǎn)動(dòng)焊培訓(xùn)工藝。通過(guò)對(duì)焊接人員實(shí)施培訓(xùn),達(dá)到了嚴(yán)格控制薄壁管焊接工藝過(guò)程的目的,使焊縫一次合格率得到顯著提高。
[Abstract]:The steel tube tower of UHV transmission line is an important part of overhead HV transmission line, and its welding quality has become an important part of the overall quality of transmission line. Because the pipe diameter and wall thickness of the column with the diameter of 273 mm, 鈮，
