Welding Round Bar to Flat

Welding Round Bar to Flat

Welding Round Bar to Flat

(OP)
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.

RE: Welding Round Bar to Flat

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.

RE: Welding Round Bar to Flat

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.
