The calculation of welding parameters is based on the method B in EN 1011-2 (Welding - Recommendation for welding metallic materials - Part 2 Arc welding of ferritic steels) described in annex C and D of this code. If an alloying content hurts this range of validity, this element as well as the CET-parameter is marked in red. The program will calculate the various carbon equivalents.įor the CET-equivalent, which is a prerequisite for the following welding parameter calculation, the range of validity is as follows (in weight %): The four carbon equivalents the most common are calculated here (in weight-%): CETĬ + Si/30 + (Mn + Cu + Cr)/20 + Mo/15 + Ni/60 + V/10 + 5*Bįill in the alloying contents given in your inspection certificate. Plenty of carbon equivalents have been developed until now with different suitability for a special welding situation and steel grade. The carbon equivalents are simplified parameters which try to estimate the influence of the alloying content of a steel by summarising the content of the various alloying elements by a particular averaging procedure. Furthermore the description of fabrication properties of our material data sheets should be taken into account and all necessary levels of a careful quality control be respected. In any case the underlying welding and construction standards have to be obeyed. Therefore, this program does not give an assurance in respect to the properties of the welded joints. The data calculated by this program are for information only and do not cover all details of a welding procedure. Thanks so much….Carbon Equivalents Welding Parameters / Preheating Effective Heat Input / Cooling Time Hardness in the HAZ Index = (Fillet Weld Volume x Lenght of Welding / 1000) x 2 Calculate the welding lenght if size of fillet 8mm and lenght of welding 12000mm with welding typy: Calculate the welding lenght if size of fillet 16mm and lenght of welding 2600mm?Ģ. Please calculation or convertion to fillet 6mm (Fillet Weld Volume) for Fillet Size 10mm.ġ. If you exercise, may be any different result of value fillet weld volume (Convertion fillet 6mm).
Welding calculator excel how to#
In this occasion I will share the experience of how to calculate the length for type welding welding as follows:
The primary key to determining the welding lenght the first we have to find the amount of work volume we will calculate. This article may not be a standard formula … which obviously can be used as an additional reference your calculation because of some of the experiences I’ve met there are some formulas used to determine the welding lenght. In this post I want to share knowledge about how to calculate the lenght of welding.
