Table 7 shows the commonest welding consumables that are used for dissimilar metal welding. Basically, such welding consumables should be used that satisfy the mechanical properties of at least one of the base metals of the joint. Below are supplementary comments to Table 7. In welding of carbon steel with austenitic stainless steel, 309
Bend Test on dissimilar metals 309 filler on Carbon?Oct 12, 2007 · However, it bother me that someone is still using 309 for dissimilar metal welds in superheater tubes. I thought folks learned a long time ago to use Inconel filler to avoid the weld failures due to carbon migration. I guess that just means job security for you and the other welders that get to repair them later on. By
Aug 11, 2003 · Hi, Does anybody advise me that which electrod & filler rod may be used to weld DUPLEX STAINLESS STEEL (N06002), P no 10H to Carbon steel , ASTM A 36 , P no 1 1- Er 309L for filler rod and 2- E 309 L for Electrode or same filler rod & electrod used for Duplex SS is ER 2209 & E 2209 In my opinion ER or E 309 we may use, since this electrode mostly used for dissimilar welding.
Dissimilar Materials Weldability Concepts - EWIWeld Metal 308 L 19 29 84 Buttering 309 L 19 40 95 Furthermore, different metals have different weldability, so we need to understand the nature of the metal to be welded. Selection of consumables with minimum martensite in the as-welded microstructure.

For Stainless Steel - Kobe WeldingProper welding speeds are approximately 30-70 cm/min in horizontal fillet welding. With a 309 type wire, dissimilar-metal welding of stainless steel to carbon steel can be done in the same welding condition as used for welding stainless steels. However to secure the ferrite content of weld metal,
Improved Filler Metal Enables Higher-Temperature Jul 01, 2009 · In dissimilar metal welds using conventional filler metals, carbon can migrate, under increased temperature, from the low-alloy base metal to the high-alloy filler metal, creating a
Maxfil-309 is an all position stainless steel flux cored wire to deposit good oxidation resistance (up to 1100°C) weld metal with radiographic quality. The wire have smooth and stable arc with good slag detachability. Maxfil-309 is suitable for joining of dissimilar steels like 304 type stainless steels to mild steel & low alloy steel, cladding & overlaying applications, joining of
Selecting Filler Metals for Dissimilar Alloy Welding A common question I receive is the proper alloy filler metal for joining two dissimilar metals. The difficulty is there is not normally one straight forward answer. For example, when joining two different heat resistant alloys, there are several factors that are important.
Welding Consumeables - TIG Rods and TungstensAnd those numbers are incorporated into the filler rod classifications. Basically, stainless steel is divided into three categories worth noting:austenitic (such as 302, 306, 308, 309), martensitic (such as 410, and 416), and ferritic ( 409, 430). If you're not sure what kind of metal you have, the ferritic stainless steels stick to a magnet.
Welding Dissimilar Metals Using 309 Stainless Steel Q:We commonly build and weld carbon steel parts with a standard ER 70S-6 wire using a 98 percent argon/2 percent carbon dioxide shielding gas. Recently we've begun manufacturing parts that combine carbon steel, ferritic stainless steel, and other grades of stainless steel (SS) using a 309LSi
When should I use ER308L, ER309L or ER316L? Welding SupplyUse ER309L (including ER309LSi) when joining mild steel or low alloy steel to stainless steels, for joining dissimilar stainless steels such as 409 to itself or to ER304L stainless, as well as for joining 309 base metal. CG-12 is the cast equivalent of 309. Some ER308L applications may be substituted with ER309L filler metal, but ER316L or
When to Use 308L, 309L or 316L Filler MetalCG-12 is the cast equivalent of 309. Some 308L applications may be substituted with 309L filler metal, but 316L or 316 applications generally require molybdenum and 309L contains no molybdenum. Type 347 stainless steel filler metal is ideal for 347 and 321 base
Use 309L (including ER309LSi) when joining mild steel or low alloy steel to stainless steels, for joining dissimilar stainless steels such as 409 to itself or to 304L stainless, as well as for joining 309 base metal. CG-12 is the cast equivalent of 309. Some 308L applications may be substituted with 309L filler metal, but 316L or 316
