摘要
为了得到较高焊接质量的铝合金螺旋焊管,提高焊接效率,采用新型双面双弧脉冲波控TIG焊接技术对6 mm、7 mm、8 mm、10 mm高强耐蚀铝合金板材进行了焊接试验,并对所焊试样的焊接接头进行了射线和金相检测。检测结果表明,采用双面双弧脉冲波控TIG焊接工艺,焊缝成形美观,无气孔、夹渣、焊瘤、咬边等缺陷;焊缝内部质量、金相组织符合标准规范要求。
In order to get higher welding quality aluminium alloy spiral welded pipe, and improve the welding efficiency, it adopted newer double side double arc welding technology to conduct welding tests on 6 mm, 7 mm, 8 mm and 10 mm thickness high strength aluminium alloy steel plates, and carried out X-ray testing and metallographic test. Test results showed that adopting the double side double arc pulse wave control TIG welding process, weld appearance is good, without stoma,inclusions, welding beading, undercut and other defects; the internal quality of weld and metallographic organization conform to the requirements of the standard specification.
