摘要
分析哈氏合金B系列合金的焊接特性,结合在实践中成功焊接哈氏合金B-2的经验,指出焊接时容易出现焊缝金属污染和焊接接头的中温敏化脆化,解决的关键是重视焊前处理和对高温焊缝的保护以及控制焊接线能量。
Through analyzing the characteristic of ＂B-type＂ and with successful experience for welding hastelloy B - 2, welding technology for ＂B-type＂ alloy was introduced. It was important to prevent contamination and intermediate temperature cracking in the welding process by preweld treatment and controlling welding heat input.
