How is the work positioned for a 1F Tee joint?

For a 1F Tee joint, both members are tilted about 45 degrees to the horizontal. This puts the weld face in a comfortable reachable plane, gives you good visibility of the root, and lets gravity help keep the molten metal where it belongs in the joint. With this setup, the torch angle and travel along the intersection allow a stable fillet bead and better control of penetration on both sides of the Tee. If the parts were flat or had more extreme orientations, the puddle would be harder to control, visibility would suffer, and the bead could sag or be uneven. So, tilting both members to about 45 degrees provides the most practical balance of accessibility, control, and weld quality for a 1F Tee weld.
