SS Anchor Bolt question
SS Anchor Bolt question
(OP)
We have a transmission tower out in some salt water in a bay (up on piers but in the splash zone) that someone put in with SS anchor bolts. The drawings do not specify the grade or type of SS that was used. One of the anchor bolts (cast in concrete) got damaged so we need to break the concrete down and weld a new piece of SS onto the bolt shaft.
I don't have any experience with SS and had a couple of questions.
What type of SS might have been used for the original bolt and nut? Is there an easy test to determine type? (probably not)
What weld rod should be used to join the new to the old? I was going to specify a small angle as a splint and use a fillet weld in addition to a butt weld.
The bolts are about 1" diameter.

RE: SS Anchor Bolt question
inch-pound units:
screw: ASTM F 593 Group 1
nut: ASTM F 594 Group 1
metric units:
screw: ISO 3506-1, A4-70
nut: ISO 3506-2, A2-70
Easy test: portable x-ray fluorescence (XRF) tester or send a piece to a lab and use XRF or energy dispersive x-ray spectrometry or optical emission spectrometry.
You absolutely should not weld structural fasteners - you will ruin the properties. You need to replace the fasteners with new ones.
RE: SS Anchor Bolt question
Anybody else have an idea on how to butt splice 2 SS bolts together?

RE: SS Anchor Bolt question
A coupling nut seems suited for this application.
