Abstract
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.关键词
