Abstract
In order to reasonably control the weld fusion line width of HFW pipe, increase the welding quality of welded pipe products, taking some specification three steel grade (B/X52/X60) HFW pipe as example, the weld properties were detected according to the relative requirements of API SPEC 5L and GB/T 9711. The results showed that HFW weld fusion line width reduce with pipeline steel carbon content reducing;for welded line pipe, the fusion line size (fn) of weld central section in the range of 0.02~0.08 mm, f0/fn is in the range of 1.9~2.3, It is helpful to prevent the harmful welding caused by the insufficient heating, and also helpful to the normal discharge of the oxide, so as to guarantee the quality of HFW welded pipe products.关键词
