Specifying Weld at Angled Truss Connection?
(OP)
I want to know how to specify a weld to get an effective throat equivalent to 3/16" fillet weld. See the attached sketch. Thanks!
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Specify the weld as you would for a "regular" (90°) fillet weld, but with the dimensions adjusted to your situation.
In the USA, I believe z-value is mostly used (leg length), in Europe we always specify a-value (throat depth).
Specify either one of those (according to your location) to your minimum requirements.

The above quote is from Article 8.2.6 of "Hollow Structural Section Connections and Trusses". As shown elsewhere in the book, the fabricator has more than one option to achieve the desired result.

When full strength development is required, special measures are needed to develop the section where the wall is at an angle to the surface to which it is connected. These are outlined in the book I referenced earlier.

1. How is the effective weld size calculated for fillet welds at acute and obtuse angle?
2. How are (partial penetration) welds specified with an effective weld size equal to a 3/16" fillet?
3. Can the effective weld size be specified for fillet welds in lieu of the leg length?

Note that the vertical walls of the HSS are getting a greater length of weld because of the slope than they would if they met the chord at right angles. If the angle is 45o, they are getting 1.41 times the length of weld which means the toe weld is not quite so critical.
