metric weld dimensioning
metric weld dimensioning
(OP)
I believe standard US practice is to dimension a fillet weld by the leg length. I heard from a normally very reliable (but somewhat vintage) source that European standard is to call out the weld throat dimension. I have not been able to confirm (or deny) that after pretty extensive Googling.
Does anyone know the truth, and governing spec?
thanks,

Oddly, I have had yet to find a valid (metric units, Euro-fillet throat dimension) fillet weld gage. The standard US fillet gages can be used of course, but the numbers (labels) for each size must be "converted" to a "mm throat length" equivalent.
And, obviously, require the assumption that both legs are the same size, and that the fillet is actually at a 45 degree angle in a 90 degree joint.

Mine is Facom ( www.facom.fr ) - item reference: DELA.1960
But as (almost) everything here welding related has only the throat specified (and not the leg length), you can buy those from about every welding wholesaler.
Easy as pie: the two 'legs' make a 90° corner, and you just slide the middle part towards the weld. If the weld is symmetrical, you read the throat from the vernier.
If the weld isn't symmetrical, you still have got to eyeball it...
the angles on each extension are for checking weld preparation (V-grooves).
