SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

BOILERMAKER

Starbase is standing up on-site power generation for the Starbase supercomputer. This boilermaker role builds the plate, duct, and tank side of that plant. You fit, align, and weld turbine exhaust duct, selective catalytic reduction (SCR) casings and stack shell, and aqueous ammonia tanks. Where the steam side is set, you also install HRSG or steam-generator casing, modules, and pressure parts so the packages can be tied in and tested.

RESPONSIBILITIES:

Fit and weld turbine exhaust duct from the package outlet to the SCR, including spools, expansion joints, dampers, and turning vanes

Assemble SCR housing, stack shell, liner plate, and casing; land sections on the structural steel and bolt and weld them per drawings and specs

Erect and weld aqueous ammonia storage tanks and other field-erected or shop tanks; fit nozzles so pipefitters can tie in

When HRSG or steam-generator parts are on the job, install casing, modules, headers, and tubes; align and weld pressure parts to the weld map and WPS

Lay out, cut, bevel, and fit plate; set gaps, hi-lo, and alignment before weld-out, including purge and preheat where the WPS requires it …
