如何选择正确的不锈钢焊材?
How to choose the right stainless steel welding material?
如果母材是相同的,首要准则就是“与母材匹配”。例如焊接310或316不锈钢,就选择相应的焊材。
If the base metal is the same, the first criterion is "match with base metal". For example, welding 310 or 316 stainless steel, select the corresponding welding material.
焊接异种材料,则遵循选择与合金元素含量高的母材相匹配的准则。例如焊接304和316不锈钢,则选择316型焊材。
The selection criterion of high content of dissimilar elements should be followed. For example, if 304 and 316 stainless steels are welded, type 316 welding materials are selected.
但是,也存在很多不遵循“匹配母材”原则的特殊情况,这时就要“查阅焊材选择表”。例如,304型不锈钢是最常见的母材,但是没有304型的焊条。
However, there are many special cases that do not follow the "matching base metal" principle, so it is necessary to "consult the welding material selection table". For example, type 304 stainless steel is the most common base metal, but there is no 304 type electrode.
假如要焊材与母材匹配,如何选择焊材来焊接304不锈钢?
If you want to match the base metal with the welding material, how to choose the welding material to weld 304 stainless steel?
焊接304不锈钢时,使用308型焊材,因为308不锈钢中的额外元素可以更好的稳定焊缝区域。
When welding 304 stainless steel, use 308 welding material, because the additional elements in 308 stainless steel can better stabilize the weld area.
308L也是一个可接受的选择。L表示低碳含量,3XXL不锈钢表示碳含量≤ 0.03%,而标准的3XX不锈钢可最高含有0.08%的碳含量。
308L is also an acceptable option. L is low carbon content, 3xxl stainless steel is carbon content ≤ 0.03%, while standard 3xx stainless steel can contain up to 0.08% carbon content.
