【摘要】：不銹鋼復合鋼板具有強度高、耐腐蝕、耐磨損、壽命長等性能,在石油化工等各個領域中替代奧氏體不銹鋼被廣泛應用,特別是用于壓力容器制造。但是,不銹鋼復合鋼板存在著復合層厚度不均勻的現(xiàn)象,加工坡口剝離復合層時,易產(chǎn)生復合層剝離不干凈的現(xiàn)象,在焊接基層時,會將殘余在基層上的不銹鋼熔化,導致焊縫中的合金元素增加,焊縫變得硬而脆,容易產(chǎn)生裂紋。因此,對不銹鋼復合鋼板焊接性能研究具有一定的工程應用價值。 本文對復合鋼板焊接工藝及技術(shù)的國內(nèi)外發(fā)展動態(tài)進行了綜述；對不同合金元素和組織狀態(tài)對材料的焊接性能、使用性能的影響進行了分析和總結(jié)。通過對不銹鋼復合鋼板的焊接特性進行理論分析并結(jié)合現(xiàn)場試驗結(jié)果,提出一些適用于常用不銹鋼復合鋼板的焊接工藝。論文研究結(jié)果表明,在不銹鋼中加入穩(wěn)定化元素,焊接時,可先于鉻形成碳化物,從而保證焊接接頭的耐蝕性；在焊接不銹鋼復合板過渡層時,要使用鉻、鎳含量較高的焊接材料來提高抗裂性,保證焊接質(zhì)量。
[Abstract]:Stainless steel composite steel plate has many properties, such as high strength, corrosion resistance, wear resistance, long life and so on. It is widely used to replace Austenite stainless steel in petrochemical and other fields, especially in the manufacture of pressure vessels. However, there is a phenomenon of uneven thickness of composite layer in stainless steel composite steel plate. When machining groove peeling composite layer, it is easy to produce the phenomenon that composite layer peeling is not clean. When welding base, stainless steel residual on base layer will be melted. Resulting in the increase of alloy elements in the weld, the weld becomes hard and brittle, easy to crack. Therefore, the study of welding performance of stainless steel composite steel plate has certain engineering application value. In this paper, the development of welding technology and technology of composite steel plate at home and abroad is reviewed, and the effects of different alloy elements and microstructure on the welding properties and service properties of composite steel plate are analyzed and summarized. Based on the theoretical analysis of the welding characteristics of stainless steel composite steel plates and the results of field tests, some welding processes suitable for common stainless steel composite steel plates are put forward. The results show that when stabilizing elements are added to stainless steel, carbides can be formed first from chromium, so as to ensure the corrosion resistance of welded joints. When welding the transition layer of stainless steel composite plate, the welding material with high content of chromium and nickel should be used to improve the crack resistance and ensure the welding quality.
