3.1 Weld strength Weld strength is an important criterion for assessing weld quality. The welded joint strength is measured either as breaking load (N) of joint [2,4,11,111,121,122] or as weld strength per unit length of the weld (N/m) [19,34,62,74,83,91] or as shear or tensile...
In all probability, the designer would have been completely ignorant of the poor fatigue strength of fillet welds, and the likelihood of fatigue failure of the connection. Smith (2002) published an investigation of weld fatigue cracks in the aluminum alloy frame of a fire-fighting platform. ...
In many situations the application of heat may haveadverse effectslike crack formation, hardness and strength changes, production of brittle phases, microstructural modifications affecting corrosion resistance properties, unacceptable deformations, alignment and fit problems, introduction of residual stresses. If...
Using t-1/16 as the max size will get you into trouble if you are trying to develop the full strength of the steel - take for instance an HSS Column welded to a base plate, the fillet weld can only be made on one side due to access issues. If you are trying to develop the ...

Minimum Fillet Weld Size per AWS D1.1 Table. When weld fillet size is not specified on engineering drawing, the following general guidance apply per. AWS D1.1. Weld sizes should be determined based on structural requiremnts and specified. ...
For quenched and temperedhigh strength low alloysteels, it is imperative to establish the minimum but not to exceed the maximum temperature given by handbooks or by manufacturers. In fact a too high temperature Weld-preheating mayreduce too muchthe cooling rate. ...
The tensile strength of 200mm x 20mm GMAW welding plates was evaluated through the use of testing procedures. The results of the experiments were evaluated using the RSM approach, and the findings demonstrated that the current, voltage, and travel speed were the pr...
So, it was considered to evaluate tensile breaking load and displacement in 25 mm gauge length for weld joints instead of usual tensile strength, yield strength and elongations which are dependent of cross sectional area of test specimen. The transverse tensile properties of EB weld joints and...
