He was burning in a 6G position—the Everest of pipe welding. The joint was a 12-inch schedule 80 carbon steel pipe, fixed at a 45-degree angle. To pass this test, or to pass this real-world repair, a welder had to weld overhead, vertically, and horizontally all in the same bead. Leo wiped the sweat from his eyes with a greasy forearm.
“Show-off,” Kincaid muttered, but there was respect in it now.
Leo didn’t answer. He was watching the puddle. In the 6G, the molten metal wanted to drip out like honey off a spoon. You couldn't fight it; you had to dance with it. He jammed the 6010 rod into the bevel, pushing it uphill against common sense. The key was the keyhole—that tiny, glowing gap at the leading edge of the puddle. Too big, and you blow through. Too small, and you lack penetration. Leo’s hand moved in a tight, rhythmic weave: two steps up, one step back.
The hiss of the arc was a whisper compared to the thunderous roar of the refinery’s flare stack. Sixty feet up, on a scaffold that creaked with the shifting Gulf wind, Leo Marino understood the first law of the pipe welder: gravity is never your friend.
Leo dug the grinder out of his belt. He ground the bad spot down to bright metal, the wheel screeching in the confined space. He took a breath. He repositioned his legs. He struck the arc again, this time changing his angle. Instead of pulling the rod, he pushed it slightly—a modified 5G technique few knew. The puddle flattened. The slag flowed behind like a wave.
Pop. A flash of white. Porosity.
