Welding Round Bar to Flat

[jike]

How do I determine the size (depth and width) of the required partial penetration groove weld to achieve an effective throat of say 1/8"? I am looking at joint T-P10-S for SAW. The round bar is solid 1.25" diameter so T1 is not applicable. Perhaps joint T-P10-S is not what I should be looking at.

jike;
You are referring to a flare bevel groove weld? If so, there are equations in AWS for determining effective throat.

I am aware of these but am confused. I was hoping someone would be kind enough to help me understand them.

Refer to D1.1 (00 or 02) Section 2.3.1.4 which refers you to Table 2.1. Also check AISC 13 edition, page 16.1-94, table J2.2. Note that in addition to the radius of the bar, the welding process selected can also affect the value of (E).

FYI, Figure 2.1 (A),D1.4-98 (rebar welding code) shows what the flare-bevel groove weld(s) would look like between a round bar and flat planar surface.
