Pipe pile to cap beam connection
Pipe pile to cap beam connection
(OP)
When connecting a pipe pile to an embedded plate on a cap beam of a bridge pier, which type of weld works best? fillet or a groove weld with a steel backing ring? I was told it is difficult to get a proper weld because of the difficulty in getting all the pile tops level enough to get each plate flush with the pile. Any thoughts?
I've seen the connection done using both types of welds
(see attached)
option 2 would seem to provide the best option.

Fillets are much easier to do, specially with limited access. In my experience the possibility of deffects is smaller. The test requirements are much more reasonable. You do not need that backing plate that will never be fitted properly. Easier pre-qualification of the weld...
If it works structurally (and I do not see why it should not if designed properly), my vote is for fillet weld
