Field weld vs. shop weld

[braves25]

Hello all.....when determining the capacity of a field weld vs. a shop weld, is there any additional safety factor to be applied to the field weld? I have always been told to provide an additional 2.0 FS to any field welds; however, I cannot find any documentation of this. Would a field weld require additional inspection to have the same capacity of a shop weld (all other things equal)?

Thanks and have a great day.

XR250... flux core is a commercial process. It is common for the homeowner buzz boxes as well. Most field welding is still done with stick welding...mostly because the equipment is simple and portability is easier, plus its familiarity and control with welders is much better.
