She adjusted. The second pass—the hot pass—went in. She fed the filler rod with her left hand, a steady rhythm she’d learned decades ago. Her right hand guided the torch in a tight weave, side to side, pausing on each edge to let the puddle fill the undercut. In 2G, the top edge always wants to undercut—to dig a groove next to the weld. She compensated by holding the torch a fraction of a second longer on the upper plate.
“It’s just a 2G position,” said Commander Elias, floating upside down beside her. “Horizontal groove. Like welding a pipe to a wall. You’ve done it a million times.” 2g position
Mira stared at the gash in the outer hull of the Odysseus , a research station orbiting Jupiter’s moon, Europa. The gash was a meter long, jagged as a lightning bolt. Behind it, the station’s atmosphere hissed into the void. A temporary patch had been slapped on, but it was failing. In twelve hours, the patch would blow, and everyone inside would be dead.

She remembered her father, an old pipeline welder in Texas. He’d taught her on scrap metal in the backyard. “The 2G position is the liar’s weld,” he’d said. “It looks easy because it’s horizontal. But it’s the first one that separates the artists from the hacks. You have to move fast enough that the puddle doesn’t drip, slow enough that it fuses. And you have to watch .” Her right hand guided the torch in a
