Welded Splices of Steel Pipe Piles?
Welded Splices of Steel Pipe Piles?
(OP)
For ERW steel pipe piles used in stardard building foundation applications, are there any special concerns regarding welded splices? I believe all ASTM A252 says is that the weld must provide the required strength during driving and service, nothing too specific.
Is a full-penetration weld using an AWS approved procedure summarily acceptable? Or are there other things to consider?

A partial pen weld should be sufficient. Also, the joint prep will leave a lot to be desired. A single bevel would be the easier profile to get, but it will likely be done with a torch in the field.
I would suggest guide tabs for alignment or a splice ring designed for such.

Why wouldn't you get a full pen weld from a welder qualified for pipe welding? For example, if I call for a 50' long pipe pile, they aren't going to automatically provide me a full pen weld wherever they place the splice?
Why wouldn't this be done in the shop?

No..it is almost never understood that a full pen weld will be provided for splices in pipe piles. Most often it is a "seal weld" with little or no preparation.
Yes, a qualified pipe welder could get a full penetration weld on a properly prepared joint in the field; however, you are not likely to get a pressure piping welder on the job...more likely a general field welder so be aware of the quality variation you might get.

Probably due to transport restrictions. 40' may be the longest that can be transported without a long load escort?
