采用降低复盖层始焊温度的工艺措施,解决了过热器管焊接长期不能解决的问题,对其他较小直径的管道焊接也具有实际参考价值。
Adopting the technical measures of reducing the initial welding temperature of the overlay, the problem that the welding of the superheater pipe can not be solved for a long time is solved, and the welding of other smaller diameter pipes is also of practical reference value.
