Welding rebar to pipe. What size weld, how long?
Welding rebar to pipe. What size weld, how long?
(OP)
Currently I am working on resolving a request for information. We have piles with rebar that hooks into the concrete foundation. In some of these piles the rebar has been broken and cut. My boss would like me to have new rebar welded to the outside of these piles. I am trying to figure out where in the AISC manual I can find an equation to figure out how long the weld will need to be and what size weld I will need. I'm just an intern trying to do a good job. Please help. I have looked through the weld section and I noticed equation (8-2b). Can this be used to figure out the length and weld diameter for welding two round steel objects together? Also, what type of weld would you use for welding a pipe and rebar together?

The attachment sounds like an axial fillet weld welding the re-bar to the pipe??
I think we need more info, but also agree - welding re-bar without the right material and welding spec / consumables / preheat is normally a recipe for later disaster. It really doesn't like it.
search "welding rebar" and you find gems like this http://www.eng-tips.com/viewthread.cfm?qid=55969

Ron and LittleInch are right -- the process will be the critical element here. Probably best to get that figured out first.

Correct the piles are metal pipes and the rebar is attached to anchor the slab. I am trying to restore the tensile capacity of the rebar. I was told that we will be using #8 hooked bars for the new bars that are going to be welded to the pile. I will look into section J2 of the AISC manual. As far as the process goes I am not too sure about that.
