I have a question regarding butt weld qualify all type of joint according to 8.4.3 in 15614. For example , my test piece is as follows:-
type of weld: butt weld
type of joint: butt joint
process: FCAW (132)
My plan is to qualify the test piece for both butt weld and fillet weld according to the clause below
In b) , it is stated clearly that my test piece can qualify for both butt and fillet weld at any type of joint.
What i don’t understand is the statement in a) . Does it mean if I want to use T-joint, i still need to have additional test piece to qualify T-joint welding?
My second question is, If i qualify fillet weld via butt weld test, should i take the the thickness range as highlighted in table 8? and my throat thickness should be no restriction.
Thank you very much!
