WELDING FOR SA335P91 AND SA213T91 STEELS IN POWER BOILER PRODUCTION
Harbin Boiler Company Limite Huo Shijun, Li Hong hen, Zai Jun
Abstract The materials of SA335P91 an SA213T91 have some functions such as goo mechanical properties, heat- resis
tance, corrosion- resistance an creep- resistance, at a very poor circumstance. They however have poor wel ability an high
technology requirement. This article provi es a reasonable wel ing technology accor ing to their characteristics, this wel ing tech
nology has been use in the manufacturing of boiler heating parts an the quality is reliable.
Key words: SA335P91 and SA213T91 steels, power boiler, girth weld, fillet weld
