The applicat ion of the power plant T91 / P91 steel welding technology and welding protective agent described in this steel Welding, proposed T91/P91 steel protection during welding points, making T91/P91 steel welded under more reasonable specification parameters to ensure the quality of welding. The experiment shows, welding protective agent used in the T91/P91 steel welding, the weld joint mechanical performance indicators can meet the requirements, and the process is easier, especially in the big mouth of P91 steel welding in argon substitution effect is more well, the price is cheaper than argon protection, a high promotional value.
