摘要:
针对厚壁大径管氩电联合焊的缺点,开发了窄间隙脉冲TIG自动焊工艺,解决了厚壁大直径管窄间隙TIG焊中焊缝侧壁熔透、坡口设计等难点,通过研究厚壁管窄间隙焊接焊缝侧壁熔透技术,开发厚壁大直径管窄间隙TIG焊组合坡口,设计焊接该种坡口厚壁管的特定范围的焊接工艺参数,并在焊接实例中进一步验证了该工艺技术的可靠性,成功解决了厚壁大直径管窄间隙TIG自动焊的工艺难点,并取得了良好的生产效果。
Abstract:
Aiming at the disadvantages of the TIG-SMAW for heavy wall thickness and large diameter welded pipe, the narrow gap impulse TIG auto-welding technology was developed; it solved some design difficulties in TIG welding, such as penetration in weld sidewall, bevel design and etc. Through research on penetration technology in weld sidewall for narrow gap heavy wall thickness welding, the bevel combination for TIG welding was developed. It designed specified range welding parameters for heavy wall thickness welded pipe with the said bevel, and its process was validated in welding practice; it successfully solved process difficulties of narrow gap TIG auto-welding with heavy wall thickness and large diameter, and obtained excellent effect.
