Weld Connections - 1920's Steel

Weld Connections - 1920's Steel

Weld Connections - 1920's Steel

(OP)
I have a project with structural steel built possibly in the 1920's, not really certain exactly when.  How can I determine if the steel is weldable?  

RE: Weld Connections - 1920's Steel

I am sure that someone has asked this question before. Check the past threads for anything on this topic.

RE: Weld Connections - 1920's Steel

Take a coupon and send it to a testing lab to determine weldability. The coupon must be removed in such a way as to not modify its properties.

RE: Weld Connections - 1920's Steel

How large does this coupon need to be?  

I intend on welding the bottom flange of a 15" x 60 plf section erected in 1907, to the top flange of a new section to create a built-up section for an existing facility.

RE: Weld Connections - 1920's Steel

I would do this before cutting out a piece to test.

A quick test to see if it is readily weldable is to make a one side fillet weld,7018 electrode, a 1/4" 2"x2" tab in an inconspicuous place and try to forcibly remove it.
Try first in the hard direction, hitting one time on the weld side. Then hit it from the easy side. It shouldn't break out the hard way. The weld should fail hitting from the easy side.
