CalQlata's technical support for our welding calculator that compares the strength and filler material volume of equivalent fillet and butt welds. Welding Strength Calculations. Introduction The following notes are general guidance notes showing methods of calculation of the strength and size of welds.

A Microsoft Excel Spreadsheet that calculates the Nominal Capacity of any Weld Group using Instantaneous Center of Rotation Method. It requires the coordinates of weld segments' end points as input and graphically plots the segments. It has a routine that calculates the C coefficients of common weld group patterns. Please watch out for the REVISED/CORRECTED version of 'WELDING CAPACITY CALCULATOR' standalone application I posted earlier.

Bugs and mathematical errors are already addressed in this version. Deixem o pimba em paz.

Note:. We do not recommend that you use plug, groove, and spot weld joints under the fatigue loading. The calculations of this joint are not available. Origination of sudden brittle fractures, changes in the mechanic values of the material caused by the temperature and residual stress affects, are not taken into account in the calculation. The calculation does not apply to weld joints requiring special standards (for example, pressure vessels, cranes, excavators, piping, and so on). Only nominal stress for the particular loading in a certain section is specified by the calculation.

The stress concentrations and internal stresses are not taken into account.
