Crl8Ni9Ti austenitic stainless steel joint such as distribution of hardness, strength and impact toughness change little. Furthermore the fractures of impact and tensile are characterized by dimple as same as those of conventional TIG welding.

• 涂活性化焊剂焊接1Cr18Ni9Ti奥氏体不锈钢时，焊接接头的硬度、塑性、抗拉强度和冲击韧度变化不大，而且其冲击、拉伸断口形貌也与普通TIG焊的相同，为典型的韧窝型断口。
