Welding of Bent Rebar
Welding of Bent Rebar
(OP)
If I am welding a rebar with a 10 degree bend in it, onto a plate, how far away from the bend do I need to be, to start my weld? Does anyone know where I can find something in writing about this?
This diagram calls this dimension out to be 2 1/2" but I'm not sure where this dimension comes from.

Take a look at D1.4 Section 4.2.6 and Figure 4.2 which call out a minimum distance from the point of tangency equal or greater than 2 bar diameters.

If the length were longer, more weld (more time, more metal, more cost) would be needed as the bar bends away from the tangent, and little added strength would be added since the extra weld would "fill in" the increasingly large gap.
Unless you see something to indicate there is a problem, weld it per plan.
Note the symbol - He wants you to weld both sides of the bar.

I was assuming the load on the bar is tension, in the length (axial direction) of the bar so the stress tends to "close up" the bar and reduce the angle.
You think it's pulling "away" from the bend - radial to the bar and weld.
