Weld weave size Vs. mechanical properties

2008-11-3 · I know that the common rule is weave no greater then 1.5 electrode diameter. That is great for SMAW but what about GMAW or FCAW or GTAW. And if it does have a detrimental effect on the mechanical properties what is the maximum weave that you would probably be safe with for wire processes. Thanks to all who respond
