Optimum root opening
Optimum root opening
(OP)
What is the optimum root opening, for complete penetration weld, in a single pass, one side only for the material and joint described below?
Weld process is GTAW, 3/32 tungsten, 2% thor.
Titanium 6Al 4V, 0.100” thick
Single V butt joint, 60 Deg included angle with 0.025 root face.
Also, please direct me to any formulas that apply for determining root opening.
Thank you,
Dave

RE: Optimum root opening
0.031 to 0.125", root opening should be between 0-0.10t (t=thickness) with square groove butt joint (no bevel).

RE: Optimum root opening
I am using the 0.0-0.1t for the root opening.
Welding 0.100” thick 6-4 Ti ,I am having difficulty achieving complete penetration the length of the plate.
I am running at 200 to 230 amps: Utilizing an inert atmosphere glove-box
My usual Ti welding is from 0.005” to 0.070”, welds within this range are just fine.
The 0.100” thick Ti is presenting a bit of a problem.
Any suggestions?
