The lower carbon content is ideal for applications that have a risk of intergranular corrosion cracking. Nickel welding rods will … Preheating, postheating (to control cooling rate), and sometimes even heating during welding become necessary to produce acceptable welds and to control the mechanical properties of the steel after welding. Dissimilar welding applications include joining Inconel® 800, 600 and 601 to carbon steels, stainless steel, joining nickel 200 to stainless and joining stainless steel to carbon steel. 309 is usually the filler metal chosen for welding stainless to carbon steel when the composition of both are known. 12-08-2005, 07:35 PM I don't usually weld much of this type of material but i needed to make some hay rings for my cattle and i was wondering what type of rod i should use since im using high carbon oilfield sucker rod. Welding Inconel® alloy 600, 601 and Incoloy® 800 to themselves or to each other. Carbon steels may be more prone to hydrogen associated defects than austenitic stainless steels and so careful drying of welding consumables is advisable. Nickel and carbon steel weld together just fine, I do it quite a bit when making damascus. Almost 85% of the metal produced and used is steel. The term steel encompasses many types of metals made principally of iron. The higher silicon content serves as a deoxidizer and helps remove weld impurities and increase weld puddle fluidity. Pure nickle is used a lot in mosaic damascuses and the like to make a high contrast and striking pattern. Like carbon, this … Selection of welding consumables (filler) Ambient service temperatures. For dissimilar joint welding (example; Stainless Steel to Carbon Steel) Consideration: Failure can occur as a result of low alloy mixtures if the incorrect filler metal is selected, or if dilution rates are too high. Steel is an alloy of iron and carbon, but steels most often contain other metals such as manganese, chromium, nickel, etc., and nonmetals such as carbon… Another property of nickel is that it remains soft and ductile after the weld is done. With 0.45 to 0.75 percent carbon, these steels can be challenging to weld. Part I focuses on the fabrication and welding of nickel alloys as they relate to the welders and production personnel engaged in fabrication of nickel alloys for corrosion service. It stands to reason that if inconel 625 can be used to clad steel or chromium steel boiler tubes, it is also a good choice as a welding rod for welding steel to other metals. Nickel alloys are sometimes used for welding stainless to carbon because nickel alloys wont become hard and brittle no matter the carbon content of the steel. As the nickel content increases, the steel’s hardness increases. The base metal can become hard but the weld metal wont. Oxide inclusions and lack of inter-run fusion. It is also important to use proper filler materials to alloy Oxide trapped in the weld pool will form inclusions.
