calculation of weld face strength
calculation of weld face strength
(OP)
Greetings,
I am curious about the experience of other users of the group in calculating fillet weld strength.
Normally, we calculate the weld throat strength using the combined stress formulas based on the unit section properties of the weld (such as in Blodgett, and others).
Have you calculated the strength of the weld face? For simple uniaxial or biaxial loading this is easy but most of the time we have to deal with significant loads in 4 or even 5 directions, does anyone know a simple way to calculate this strength?

RE: calculation of weld face strength
The is no "simple way" to calculate the resulting stresses from forces in 5 or 6 directions (are you including multiple moment reactions as well as the 3 x, y, z shear forces?).
Each part of the complete welded joint, once solidified back into crystals between the two base metals, the two heat-affected zones, and the weld metal itself, behaves just like any other metallic crystal under stress and strain. The "face" of a welded fillet will yield (or not yield, or deform plastically) based on the strength of the weld and the base metal.
