How much do boilermakers make in South Carolina in 2026?

Boilermakers in South Carolina earn a median annual wage of $74,840, which works out to roughly $35.98 per hour based on a standard 2,080-hour work year. That figure comes from the Bureau of Labor Statistics Occupational Employment and Wage Statistics (OEWS) survey, published May 2025.

The pay band across the middle of the workforce is unusually tight. Workers at the 25th percentile take home $74,830 per year ($35.98/hr), while those at the 75th percentile earn $75,630 per year ($36.36/hr). That $800 spread from the bottom quarter to the top quarter is narrow compared to most trades. What it tells you is that the bulk of employed boilermakers in South Carolina are clustering around a single wage band — likely driven by project-based work at industrial facilities, power plants, or chemical plants where rates are set by contract or prevailing-wage rules rather than individual negotiation.

The $0.38-per-hour difference between the 25th and 75th percentile ($35.98 vs. $36.36) is something to keep in mind when evaluating a job offer. At straight time, that gap amounts to roughly $790 a year. Over a career, the bigger lever is not which employer you start with but whether you land consistent hours, pick up overtime, and move toward foreman or superintendent roles that fall outside this wage band entirely.

Overtime matters significantly for boilermakers. Planned outages at power generation facilities — particularly nuclear and fossil-fuel plants — often require concentrated bursts of work on tight schedules. A boilermaker putting in 55- or 60-hour weeks during a scheduled outage can push annual earnings well above what the BLS median captures, since BLS OEWS data reflects straight-time and overtime wages combined but is based on a snapshot that may not fully represent seasonal peaks. If you work primarily outage-driven jobs, your actual annual take-home can look very different from the $74,840 median depending on how many weeks of heavy overtime you log.

Geography within South Carolina plays a role too. Industrial corridors around the Midlands, the Upstate manufacturing belt, and coastal chemical and port facilities each draw different volumes of boilermaker work. Workers positioned near heavy industrial clusters generally see steadier call-outs and less dead time between jobs. That consistency affects real annual earnings more than any small difference in the posted hourly rate.

Entry-level boilermakers and apprentices will typically earn below the 25th-percentile figure shown here. BLS OEWS wages reflect employed workers across experience levels, but apprentices in the early years of a program often earn a percentage of journeyman scale — commonly starting around 50–60% and stepping up with each period completed. By the time a worker reaches journeyman status, they are competing for the rates reflected in this data set.

Some boilermakers in South Carolina work under collective bargaining agreements. If you are covered by a union contract, your wage schedule is set by that agreement and may differ from the BLS figures shown here. Check your local's agreement directly for the current scale — no general comparison to the BLS median is possible without seeing the specific contract terms.

To push your earnings above the $75,630 75th-percentile ceiling, the most direct paths are: moving into supervisory roles on large industrial projects, pursuing certifications in specialized welding procedures (such as ASME Section IX or AWS CWI), or positioning yourself for national travel work where per diem and project bonuses can add substantially to base pay. Boilermakers willing to travel for major outages and new-construction projects consistently out-earn those who work locally only.

The BLS data here does not capture per diem payments, travel reimbursements, tool allowances, or employer contributions to health and retirement benefits. When comparing offers, factor in those elements — they can shift the true value of a compensation package by several dollars per hour in effective terms.
