Welder Salary Ranges in Illinois
Not all Welders earn the same — not even close
Illinois welder specialties: (1) Caterpillar Peoria HQ + East Peoria assembly + Aurora + Joliet manufacturing plants — heavy-equipment structural welders ($65K-$95K), R&D prototype welders ($75K-$110K); (2) John Deere Moline + East Moline + Davenport (Quad Cities) — agricultural equipment fabrication ($60K-$90K); (3) Iron Workers Local 1 Chicago (structural high-rise + bridge) at $48-$54/hr scale + benefits = $100K-$135K; Local 63 East St. Louis bi-state $42-$48/hr; (4) Chicago commercial structural steel — Loop high-rise, Hudson Yards Chicago equivalent (Lincoln Yards, The 78), plus aging-infrastructure rehab (Lake Shore Drive, Chicago River bridges); (5) Lead-Service-Line replacement program (~400K LSLs targeted for 2076 completion) drives sustained piping fabrication; (6) Aerospace TIG — Boeing Defense Systems (St. Louis MO reach), Spirit AeroSystems Wichita KS reach, plus smaller IL-based Northrop Grumman Rolling Meadows; (7) CME Group + data-center alley — server-rack fabrication + cooling-system structural; (8) Downstate manufacturing — Rockford machine tool, Decatur ADM agricultural processing, Peoria CAT. Most IL welders are with AWS D1.1 + base process certs; senior structural welders carry Local 1 union scale. Here's what each tier pays in 2026:
Iron Workers Local 1 Chicago Structural
$100,000–$140,000
Union scale $48-$54/hr + benefits + multi-employer pension

Worth knowing: Iron Workers Local 1 (Chicago) is the structural anchor — about 3,500 active members covering Loop high-rise + bridge + heavy structural steel + aging-infrastructure rehab. The 4-year apprenticeship is paid from year 1 with full healthcare + multi-employer pension; admission is competitive (200-350/year). Caterpillar Peoria HQ + East Peoria assembly + Aurora + Joliet manufacturing employs the largest concentration of IL welders outside the union — heavy-equipment structural fabrication for the construction + mining + transport equipment lines. CAT cycle volatility is real (mining + construction equipment demand swings 25-40% across cycles), but R&D prototype welders + structural specialists with multi-cert stack remain durable through cycles. John Deere Moline + East Moline + Davenport Quad Cities anchors agricultural equipment fabrication. The Chicago Lead-Service-Line replacement program (~400,000 LSLs targeted for 2076 completion) creates a multi-decade specialty career path for piping fabrication welders.
Illinois welder market — Iron Workers Local 1 Chicago, Caterpillar heavy equipment, OBBBA + AGI conformity
4.95%

2.1-2.4%
Cook County effective property tax — among highest US, eats Chicago homeowner math
IL welders are -eligible — federal time-and-a-half kicks in after 40 hours a week. Illinois does not have California's daily-OT rule. The 2025 "No Tax on Overtime" deduction (federal, through 2028) lets you knock up to $12,500 (single) or $25,000 (married) of FLSA OT off federal taxable income. Illinois conforms to federal AGI as the starting point for state taxable income, so the OBBBA federal OT deduction flows through to IL state automatically — savings of roughly $620/year single, $1,240 MFJ at the cap (4.95% state).
Concrete numbers. An Iron Workers Local 1 journeyman at $50/hr base, working Loop high-rise OT — 10 OT hrs/week × 45 weeks = 450 OT hours. Premium portion (the half) is $25/hr × 450 = $11,250, capped under $12,500 single. At 22% federal + 4.95% IL = 26.95% combined → about $3,030 back single. A senior bridge welder running heavy IDOT prevailing-wage OT during summer construction season hits the cap by July. Stack a 25-year Local 1 career = $40K-$70K cumulative federal + IL savings on OT premium.
Iron Workers Local 1 (Chicago) is the structural anchor of the IL union welder market. ~3,500 active members covering Loop high-rise + bridge + Hudson Yards Chicago equivalent (Lincoln Yards, The 78) + aging-infrastructure rehab. Senior union welders + foremen $130K-$170K. The 4-year apprenticeship is paid from year 1 with full multi-employer pension + healthcare + annuity. Local 63 (East St. Louis bi-state, covers IL + MO) anchors the southern IL union side. Iron Workers' multi-employer benefits package + pension is materially more valuable than equivalent non-union package.
Caterpillar Peoria HQ + East Peoria assembly + Aurora + Joliet plants employ the largest IL welder concentration outside the union. Heavy-equipment structural fabrication for construction (track-type tractors, excavators), mining (large mining trucks 793F/797F at $5M+ each), and transport equipment lines. R&D prototype welders at the Peoria Tech Center are a smaller premium tier ($75K-$110K) doing first-article fabrication for new model development. CAT cycle volatility is real — mining + construction equipment demand swings 25-40% across business cycles — but multi-cert structural welders typically retain employment through downturns at slightly reduced hours.
Chicago Lead-Service-Line replacement program is a sleeper demand driver. ~400,000 LSLs targeted for replacement (the largest US lead-service-line program by volume), funded through 2076 with EPA + state + city + IDPH contributions. Service-line welders + piping fabrication specialists working with PEX-to-copper transitions, brass + bronze couplings, plus structural pipe support fabrication clear $75K-$110K. The Bipartisan Infrastructure Law (2021) accelerated funding through 2028.
IL flat 4.95% state income tax is genuinely manageable. A Local 1 journeyman at $115K base pays ~$5,500/year IL state. A CAT R&D prototype welder at $95K pays ~$4,500. Cook County property tax (2.1-2.4% effective) is the harder tax for working IL welders — on a $375K Chicago bungalow it's $7.9K-$9.0K/year, more than IL state income tax at journeyman comp. Most established Local 1 journeymen live suburban Cook (Tinley Park, Orland Park) or DuPage / Will County for slightly lower property tax.
Illinois for welders — Iron Workers Local 1 Chicago, Caterpillar Peoria, OBBBA + 4.95% flat
IL welders cluster in three submarkets. Chicago metro is the largest — Iron Workers Local 1 (Loop high-rise + bridge + heavy structural), Lead-Service-Line replacement program piping fabrication, Boeing Defense Systems (St. Louis adjacent reach), Northrop Grumman Rolling Meadows aerospace TIG. Peoria + East Peoria anchors Caterpillar HQ + heavy equipment fabrication. Quad Cities (Moline + East Moline + Davenport IA) anchors John Deere agricultural equipment. Downstate Rockford has a machine-tool cluster; Decatur has ADM agricultural processing.
IL welder lifestyle is bimodal. Chicago metro union welders earn top IL compensation ($100K-$140K Local 1 + benefits) but face Cook County property tax friction (2.1-2.4% effective on $375K Chicago bungalow = $7.9K-$9K/year). Most Local 1 journeymen live suburban Cook (Tinley Park, Orland Park, Mokena) or DuPage / Will County (Naperville, Joliet, Plainfield) for lower property tax + more space. Peoria + downstate welders earn less ($65K-$95K CAT) but cost of living is dramatically lower ($200K-$320K homes) — genuine homeowner economics on welder income.
Caterpillar production-cycle volatility is real for Peoria + East Peoria welders. Mining + construction equipment demand swings 25-40% across cycles tied to commodity prices + infrastructure spending. CAT layoffs during 2015-2016 + 2019-2020 affected ~6,000 IL workers each cycle; rehiring during recovery has been steady. Multi-cert structural welders + R&D prototype welders typically retain employment through downturns at reduced hours; entry-level shop welders face higher cycle exposure. The Bipartisan Infrastructure Law (2021) plus + reshoring tailwinds support sustained demand through 2028.
Late-career relocation is a moderate pattern for senior IL welders. Pritzker administration tax pressure + IL pension funding crisis + Cook County reassessment cycles + winter intensity drive outflow to FL, TN, NC, AZ, TX. Senior contractors + Local 1 retirees relocating to Naples FL or Nashville TN save 4.95% IL state on retirement income (UA Pension portable; cumulative $30K-$80K over 20-year retirement). Most Local 1 journeymen retire in IL on union pension + Social Security + ; shop owners more likely to relocate.
How Illinois taxes work for welders (and where the levers are)
IL runs a flat 4.95% state income tax with $2,775 personal exemption (single, 2026). No itemized state deduction (IL doesn't allow itemizing). A Local 1 journeyman at $115K base pays ~$5,500/year IL state. A senior shop owner at $200K owner draw pays ~$9,750. Cook County property tax (2.1-2.4% effective) is the harder tax for working IL welders — on a $375K Chicago bungalow it's $7.9K-$9K/year, more than IL state income tax at journeyman comp.
Iron Workers Local 1 multi-employer pension is the structural IL union welder retirement architecture. Local 1 funds employer pension contributions at ~$10-$13/hr on top of hourly wage. After 5-year vesting, pension service credit replaces 50-65% of final-average wages at full retirement. A 30-year Local 1 journeyman retiring at $115K final wages projects $52K-$72K/year pension for life, plus accumulation typically $300K-$550K. Local 1 multi-employer benefits package (medical/dental/pension/annuity) is materially more valuable than equivalent non-union .
Caterpillar employees have CAT-sponsored (typical 6% match) + CAT pension (closed to new hires post-2014, but legacy employees retain) + CAT employee stock purchase plan. CAT layoff cycles during downturns require diligent 401(k) contribution discipline + emergency fund. Most senior CAT structural welders accumulate $400K-$700K 401(k) plus pension (legacy) plus deferred comp.
election + Solo for IL shop-owner welders at $80K+ net SE income — saves $4K-$6K/year SE tax. Illinois imposes a 1.5% Personal Property Replacement Tax (PPRT) on S-corp net income (paid by S-corp, not shareholder) — annoying but doesn't kill federal SE-tax savings. Solo 401(k) shelters $35K-$72K/year. Section 199A 20% federal deduction applies (welder business is NOT SSTB). Illinois conforms to QBI (no add-back) — federal + IL combined savings.
- →Iron Workers Local 1 (Chicago) 4-year apprenticeship — paid from year 1 + full pension + benefits + journey-level $48-$54/hr scale at completion. Most durable IL welder career investment.
- →Caterpillar Peoria HQ + East Peoria assembly path — CAT match (6%) + legacy pension (pre-2014 hires) + employee stock purchase. Multi-cert structural + R&D prototype welders retain employment through cycles.
- → OT deduction up to $12,500 single / $25,000 on premium pay through 2028. IL conforms federal + state — flows through to IL 4.95% automatically.
- → election + Solo at $80K+ net SE for shop owners. Saves $4K-$6K/year SE tax + shelters $35K-$72K. IL 1.5% PPRT noted but federal SE savings dominate.

Three IL metros for welders — what each one looks like
Chicago Iron Workers Local 1, Peoria Caterpillar, and Quad Cities John Deere are three different IL welder careers.
Chicago Loop / North Side / West Loop — Iron Workers Local 1, Lead-Service-Line program
Local 1 union scale $48-$54/hr + benefits = $100K-$140K · senior bridge $95K-$135K · master shop owner $200K-$380KIron Workers Local 1 (~3,500 active members) covers Loop high-rise + bridge + heavy structural + aging-infrastructure rehab. Lincoln Yards + The 78 megaprojects (Sterling Bay + Related Midwest). Lead-Service-Line replacement program (~400K LSLs through 2076). Boeing Defense Systems (St. Louis adjacent) + Northrop Grumman Rolling Meadows aerospace. Major commercial employers include F.E. Moran, Hill Mechanical, ECI for piping fabrication.
Most Local 1 journeymen live suburban Cook (Tinley Park, Orland Park) or DuPage / Will County. Cook County property tax 2.1-2.4% is structural homeowner cost.
Peoria + East Peoria — Caterpillar HQ, R&D prototype, heavy equipment
CAT structural $32-$48/hr ($65K-$95K) · R&D prototype $36-$55/hr ($75K-$110K) · CWI inspector $80K-$130KCaterpillar HQ + Peoria Tech Center (R&D prototype welders) + East Peoria assembly + Aurora + Joliet manufacturing plants. Heavy-equipment structural fabrication for construction (track-type tractors, excavators), mining (large mining trucks $5M+ each), transport equipment. CAT cycle volatility 25-40% across cycles — multi-cert structural + R&D prototype welders retain employment through downturns. CAT (6% match) + legacy pension + .
Most CAT welders live East Peoria, Pekin, Morton, Washington at $200K-$320K — genuine homeowner economics on $80K welder income. Peoria proper $180K-$280K cheaper.
Quad Cities (Moline / East Moline / Davenport IA) — John Deere agriculture
Deere structural $28-$42/hr ($58K-$87K) · UAW partial coverage premium tier $32-$48/hrJohn Deere Moline HQ + East Moline plant + Davenport (Quad Cities, IA + IL bi-state). Agricultural equipment fabrication — tractors, combines, sprayers, planters, balers. UAW Local 281 (Davenport) + Local 79 (Waterloo IA) provide partial union coverage at premium scale. Fab + paint-line + final assembly welder work. Deere cycle volatility lower than CAT (agricultural demand more stable).
Most Deere welders live Bettendorf IA or Moline IL at $180K-$280K. Quad Cities IL/IA cross-border tax planning common — IA flat 3.8% (2026) vs IL 4.95% favors IA residence with IL employer.
The Illinois welder career arc
Year 1-2 (apprentice/helper): $38K-$55K. Iron Workers Local 1 (Chicago) 4-year paid apprenticeship is most valuable path — full pension + benefits + journey-level $48-$54/hr scale at completion. Trade school alternatives — Coyne College Chicago, College of DuPage welding program, Illinois Central College Peoria, Black Hawk College Moline. AWS D1.1 (Structural) + base process certs (FCAW/GMAW/SMAW) typical year 1-2.
Year 3-7 (established welder): $58K-$90K. Multi-cert build-out begins. Decision tree: Iron Workers Local 1 union path (Chicago structural + bridge + heavy) vs Caterpillar path (Peoria heavy equipment + R&D prototype) vs John Deere W-2 path (Quad Cities agriculture) vs aerospace TIG (Boeing Defense + Northrop Rolling Meadows AS9100).
Year 8-15 (specialist): $95K-$140K. Iron Workers Local 1 journey-level $100K-$140K + benefits = $130K-$170K total. CAT structural specialist + R&D prototype $75K-$110K.

Aerospace TIG at Northrop Rolling Meadows + AS9100 + DoD clearance $85K-$120K.
Year 15-25 (master / shop owner): $120K-$240K+. Shop ownership transition for non-union welders — multi-cert + savings funds LLC + own shop with 2-5 employees. Section 199A 20% + Solo + election structure tax-favorable (IL 1.5% PPRT noted). Local 1 senior foremen + shop stewards $130K-$180K. CAT R&D prototype senior welders + lead structural $95K-$130K stable.
Retirement (age 60-65): IL Local 1 union pension + + Social Security typical for retirees ($52K-$72K pension + 401(k) draw). CAT legacy pension (pre-2014 hires) + 401(k) + . Some senior shop owners + non-union welders relocate to FL / TN / NC / AZ to escape 4.95% IL state on realization stack — saves $30K-$80K cumulative across 20-year retirement. UA Pension portable; document the move.
