What is the formula for carbon equivalence in welding?
I am trying to get some information on the formula used to determine the Carbon Equivalence that is related to preheat requirements for structural steel welding. The AWS code D1.1 & D1.5 has a formula identical to the ASTM A6 formula except it includes a term for Silicon, Si.See all results for this questionWelding | Cutting | Bending | MachiningThe CEV formula is traditionally used for commercial structural carbon steel grades while the CET formula has been adapted to better correspond to Q&T steel grades. The carbon equivalent is traditionally used for judging the need of preheating prior to welding and to rank the steel weldability. The lower carbon equivalent the better weldability.Some results are removed in response to a notice of local law requirement. For more information, please see here.The equation for calculating the carbon equivalent for ASTM A615 reinforcing steel is: CE = % C + (%Mn)/6 %C and %Mn are listed on every mill certificate, and the carbon equivalent should be calculated for every mill certificate. Sometimes, the carbon equivalent may even be calculated on the mill certificate for you.
How to calculate carbon equivalent on Mill Certificate?Sometimes, the carbon equivalent may even be calculated on the mill certificate for you. An example mill certificate is presented below. The blue boxes show the %C and %Mn. Example mill certificate showing %C and %Mn (highlighted in blue) for use in the carbon equivalent formula.See all results for this question

Metallurgy Matters: Carbon content, steel classifications carbon equivalence formula Milling
These steels usually are iron with less than 1 percent carbon, plus small amounts of manganese, phosphorus, sulfur, and silicon. The weldability and other characteristics of these steels are primarily a product of carbon content, although the alloying and residual elements do have a minor influence. Plain carbon steels are further subdivided into four groups: 1. Low 2. Medium 3. High 4. Very high Low. Often called mild steels, low-carSee more on thefabricator carbon equivalence formula MillingMachining Calculators - cutting, spindle, feed rate and carbon equivalence formula MillingFeed Rate. Feed Rate Calculators can be used to find out if the spindle speed is correct for the tool and material you are using. the formula is as below: Where: S = Spindle Speed. f = Feed Per Tooth. N = Number of Teeth. Feed Rate can help you either set the spindle speed, or check the spindle speed is acceptable, a feed rate higher than the carbon equivalence formula Milling
Must include:carbon equivalenceIs there a carbon equivalent formula for steel?So, depending on the melting practices used for the steel, the carbon equivalent formula can be tweaked to provide a better fit with lab data for a particular family of steel compositions. There are several versions of carbon equivalent formula's that were developed specific to the families of steel low carbon low alloy, C-Mn, C-Mn-Si, etc.See all results for this question
