Weld Test
12" pipe, 0.500" wall, 6G, downhill. Fit it up, set your machine, run the root, hot pass, fill and cap — then the inspector cuts your coupons and grades it to API 1104. Papers, or go get your check.
Mouse: hold the left button for the arc, and move the mouse to move the rod tip (along the joint and across the gap). Hold the right button and move to tilt the rod: toward the travel is drag, back is push, up and down leans it; it stays where you leave it. The wheel sets your feed pace: the rod only goes in as fast as you feed it, so match the burn (too fast and it sticks, too slow and you lose the arc). Let go and the hood comes up; with the arc out, click the machine to set it. Q and E turn the heat, 1–4 pick the camera, + and − lean in and back. Keyboard: Space arc, arrows hand, S/W feed pace, A/D drag/push, Z/C lean. Gamepad: left stick hand, right stick rod angle, triggers feed, A arc. Phone (sideways): one finger arc and rod, a second finger tilts, slide the feed bar.
Acceptance limits follow API Standard 1104, 19th edition (1999), sections 5, 6 and 9, as posted to the public by Public.Resource.Org.
