Welder Salary in Indiana (2026)

Welder OT is structural to the comp model in IN manufacturing. Auto OEM assembly schedules routinely run 50-60 hr/week during model-changeover periods + EV battery line buildouts; pipe welding at refinery / power plant outages can run 60-80 hr/week. Stellantis Kokomo + Samsung SDI New Carlisle + Eli Lilly Lebanon all running heavy OT 2024-2027 buildouts. Total OT typically 400-900 hrs/year for mid-career certified welder = supplemental $18-40K. Pushes mid-career welder total comp from $72K base to $90-115K all-in. Specialty pipe welders at Eli Lilly Lebanon GMP cleanroom + Samsung SDI EV battery cleanroom routinely clear $115-145K total comp.

The 2025 OBBBA law (One Big Beautiful Bill Act) created a federal-only deduction on the premium portion of overtime pay for tax years 2025-2028 — up to $12,500 single / $25,000 MFJ. Premium portion equals the half of time-and-a-half. For an IN welder with 600 OT hrs/year × $32/hr regular rate = $19,200 total OT compensation, the premium half roughly $6,400 — which fully qualifies for OBBBA federal deduction. Federal savings 22% bracket × $6,400 = $1,408/year federal back.

Indiana has not formally conformed to OBBBA. The OT premium is fully IN 3% + county CIT taxable. For a Hamilton County welder (1.10% CIT): $19,200 OT × 4.10% combined = $787/year state+local on the OT compensation. Net OBBBA benefit at IN welder OT comp tier: $1,408/year federal (offset by ongoing IN state+local tax of $787 = roughly $620/year true net benefit). IN's flat 3% + low Hamilton 1.10% CIT makes the IN-side cost of OT lower than MD's combined 8.95% — at 4.10% IN-Hamilton OT cost on $6,400 premium = $263 vs MD's $573 at the same OT volume.

OBBBA phaseout: $100/$1K MAGI over $150K single / $300K MFJ. Most IN journeyman welders ($72-105K total comp) stay well below the threshold — full OBBBA deduction available. Specialty welders + pipefitters at $115-148K may approach phaseout depending on filing status. MFJ filers with high-earner spouse could hit phaseout. The IN-specific calculation: total comp = base + OT + per-diem + cert premium (AWS / 6G pipe / ASME) + shift differential.

Real numbers for an IN journeyman welder at $32/hr × 2,080 base hrs = $66,560 base + $14K OT (350 hrs × $40/hr OT premium) + $5K AWS D1.1 cert premium = $86K total. IN combined Hamilton County 4.10% × $86K = $3,526/year. Same comp in MD: $6,880/year combined. IN saves $3,354/year vs MD. OBBBA federal OT deduction $4,700 × 22% = $1,034 federal back. Compared to TN (0% state): TN equivalent saves $3,526/year IN combined — but the manufacturing density (Cummins, Caterpillar, Allison, Stellantis, Samsung SDI, Eli Lilly Lebanon) unavailable in TN.

Union pension stacking is the dominant late-career lever for trades welders. Plumbers + Steamfitters Local 661 (Indianapolis) provides multi-employer DB pension + Annuity Fund (DC) — combined typically $4,500-6,500/month at age 65 with 30 years' service ($54-78K/year). Iron Workers Local 22 (Indianapolis) similar structure. Boilermakers Local 374 (Hammond) similar. Non-union manufacturing welders rely on employer 401(k) at $24,500/year + match — Cummins, Caterpillar, Stellantis, Samsung SDI all offer 6-8% match plus pension or RSU depending on role.

Most IN welders retire in-state — IN's 0% estate + 0% inheritance (since 2013) + flat 3% on retirement income + low Hamilton 1.10% CIT (or even lower in non-Indianapolis-metro counties) makes the late-career math materially favorable. Pre-distribution relocation to FL / TN / NV is rare for IN welders compared to MA / MD / NY peers — the IN structure doesn't push relocation. Common in-state retirement: stay in Hamilton / Marion County / Hendricks County, or migrate to southern IN (Brown / Monroe / Lawrence) or Lake Michigan shoreline (LaPorte / Porter Counties) for retirement lifestyle.

IN welding work clusters across the manufacturing belt. The Indianapolis corridor (Allison Transmission HQ + IU Health infrastructure + commercial steel work + Plumbers Local 661 pipefitter + Iron Workers Local 22) houses the densest unionized welder market. The Columbus / Lafayette / Kokomo corridor (Cummins HQ Columbus, Caterpillar Lafayette, Stellantis Kokomo + battery JV, Subaru Lafayette) anchors heavy manufacturing welder density. The South Bend / Lebanon / Princeton / Greensburg corridors (AM General South Bend, Eli Lilly Lebanon $9B mfg, Toyota Princeton, Honda Greensburg, Samsung SDI New Carlisle) round out the auto + EV battery + pharma cleanroom welder markets.

Housing on a journeyman welder + OT income tier ($72-105K total comp): Hamilton County affordable suburbs (Noblesville, Cicero, Westfield outer) $400-625K · Marion County (Indianapolis proper east-side / west-side) $200-450K · Hendricks (Plainfield, Avon, Brownsburg) $400-625K · Boone County (Lebanon, Whitestown) $375-575K · Bartholomew (Columbus IN — Cummins HQ) $250-450K · Tippecanoe (Lafayette) $275-525K · Howard (Kokomo) $200-375K · Allen (Fort Wayne) $250-475K · St. Joseph (South Bend) $250-475K. Specialty pipe welder + Eli Lilly Lebanon GMP cleanroom comp ($115-145K total) can stretch into Hamilton premium tier ($550K-$850K Carmel / Fishers) with spouse income.

Most IN welders retire in-state on union pension (Local 661 / Local 22 / Local 374) or non-union 401(k) accumulation. IN's 0% estate + 0% inheritance + flat 3% retirement tax structure is materially favorable — pre-distribution relocation to FL / TN / NV is rare for IN welders vs MA / MD peers. Common in-state retirement: stay in Hamilton / Marion / Bartholomew (Columbus IN) for grandkid proximity, or migrate to southern IN (Brown County, Monroe County) or Lake Michigan shoreline (LaPorte, Porter) for retirement. Some senior welders retire to FL / TN / NC for warmer climate, but IN structure doesn't financially push relocation.

Years 0-3 (apprentice / entry): $32-58K. Ivy Tech Community College welding program (6-month certificate or 2-year AAS) or Vincennes University welding program + OJT. Starting at manufacturing shop floor (Cummins, Caterpillar, Allison, Stellantis, Honda, Subaru, Toyota assembly) or union apprenticeship (Plumbers Local 661, Iron Workers Local 22, Boilermakers Local 374 — typically 4-5 year programs). AWS Certified Welder cert at $20-30/hr. Decision point at year 3: union path (Local 661 / 22 / 374 with multi-employer pension) vs non-union manufacturing (Cummins / Caterpillar / Allison / OEM with 401(k) + match) vs specialty welder track (TIG / pipe / underwater training).

Years 3-12 (journeyman / certified welder / specialty): $52-115K total comp. Manufacturing journeyman scale $52-72K base + 400-700 OT hrs/year drives total comp $72-95K. Certified pipe welder (ASME B31.1 / B31.3 / 6G) with Plumbers Local 661 reaches $78-115K base + premium OT. Eli Lilly Lebanon GMP cleanroom welder + Samsung SDI EV battery cleanroom welder reaches $95-135K total. Maxing 401(k) + Mega Backdoor Roth (where available at corporate) is the active-duty stack. OBBBA federal OT deduction on premium portion.

Years 12-30+ (senior welder / supervisor / specialty / retirement): $85-148K depending on track. Welding foreman / supervisor at $85-125K running multi-crew operations. CWI (Certified Welding Inspector) at $78-118K QA/QC role. Specialty welder (TIG / underwater / rig / crane operator combos) at $98-148K with uncapped OT. Year 30 union retirement decision: full DB pension (typically $54-78K/year at 30 years' Local 661 / 22 / 374 service) + Annuity Fund rollover. Most IN welders retire in-state — favorable 0% estate + 0% inheritance + flat 3% retirement structure.
