The composition characteristics and weldability of 12Cr2MoWVTiB were in-depth analyzed
welding technology experiments were researched with12Cr2MoWVTiB steel of boiler coiled pipe as the research object. Test results showed that high quality welding joints were obtained
which using manual gas tungsten arc welding
selecting a diameter of 2.5 mm H10Cr2MnMoWVTiB wire as welding material
using DC in the welding
and selecting reasonable processing parameters determined by the tests.
