Welding Technique
Strongly recommend against welding a ROUND member directly to a FLAT plate. You will not
achieve adequate fusion in the interface between the ROUND member's tangent point to the
FLAT steel plate. Simply stated, this is weldment design geometry you want to avoid. And we
haven't even mentioned the potential for excessive warpage due to Mr. Heat Shrink.
Guarantee you will not achieve root fusion as you 'shoot the gap' and attempt to TIG/MIG/SMAW
the joint in that constrained geometry.
This is a classic NoNo for fabrication, and highlighted in AWS literature by the late Lincoln
Electric wizard Omar Blodgett and others since the 60s.
Change your approach. Instead, use pillow blocks or standoffs......as previously mentioned.....to
affix the ROUND member to the standoff and then the standoff to the FLAT plate. Think: insetting
the ROUND member into the "U" of a C-Channel.
You want the tangent of the ROUND bar to meet an interface without excessive "gap".
DM me if you need additional insight.
