针对连续管在现场管-管对接焊中由于对口质量存在缺陷,组对困难的问题,研制了一种用于连续管对口组焊装置。该装置采用4个自由度调整和1个焊接工位高度调整功能来保证对口质量,实现对主要尺寸规格(管径19.05~88.90 mm,壁厚2.21~6.35 mm)的连续管的管-管全位置对接焊的快速装卡组焊。结果表明:该装置完全满足现场连续管对接焊对管端对口质量的要求。 Aiming at the problem that the continuous tube has a defect in the pipe-pipe butt welding at the site because of the counterpart quality, a continuous-pipe counterpart welding device has been developed. The device uses four degrees of freedom adjustment and a welding station height adjustment to ensure the quality of the counterparts to achieve the main dimensions (diameter 19.05 ~ 88.90 mm, wall thickness 2.21 ~ 6.35 mm) of the continuous tube tube - tube full Location Butt welding quick assembly card welding. The results show that the device fully meets the requirements of on-site counterpart quality of continuous pipe butt welding on site.
