高氮奧氏體不銹鋼是含氮量在，用氮元素代替昂貴的鎳元素作為奧氏體化元素的新型鋼種[1]，由于其特有的成本優(yōu)勢(shì)，近些年許多學(xué)者對(duì)高氮鋼研制及應(yīng)用進(jìn)行了進(jìn)一步深入研究，發(fā)現(xiàn)其具有良好的力學(xué)性能和耐腐蝕性能，在生物醫(yī)藥、海洋平臺(tái)、大型設(shè)備等各個(gè)領(lǐng)域得到推廣和應(yīng)用[2]。尤其值得一提的是，由于這種材料在高應(yīng)變沖擊下強(qiáng)度及韌性較常規(guī)材料有明顯提高，這為重載及承受沖擊載荷的設(shè)備開發(fā)提供了新型材料。高氮鋼的比強(qiáng)度、比剛度隨著含氮量的提高也有明顯提升，高的比強(qiáng)度和比剛度能明顯減輕結(jié)構(gòu)重量，因此市場(chǎng)對(duì)高含氮量的材料需求更為迫切，目前含氮量在。高氮鋼的實(shí)際應(yīng)用在很大程度上受限于它的焊接性能，在焊接過程中，氮元素易在熔池中聚集成逸出，導(dǎo)致焊接接頭部位含氮量***降低，力學(xué)性能急劇下降[3]。如何降低焊接過程中的氮損失，或者在焊接過程中通過人為干預(yù)，向熔池中增氮，成為解決高氮鋼焊接的技術(shù)關(guān)鍵，這對(duì)高氮鋼的焊接材料提出了很高的要求。目前的高氮焊絲開發(fā)，一般都是基于成分匹配及焊接接頭組.織匹配原則開發(fā)的[4]，因而需要深入考察焊絲的焊接工藝性。若焊接工藝性不好，一方面氮的聚集和逸出容易導(dǎo)致氮?dú)饪缀瓦^大的焊接飛濺。浙江異種合金連接焊條工廠如果用于埋弧自動(dòng)焊、電渣焊、氣體保護(hù)焊、氣焊等熔焊方法作填充金屬時(shí)，則稱為焊絲。</p><div
