Introduction to Collision Repair

Course Description

Introduction to Collision Repair and Lab covers vehicle construction, terminology, and collision energy management in today's high-tech vehicles. Students develop an understanding of repair versus replacement techniques and the fundamentals of collision estimating, and gain hands-on experience with basic industry welding techniques. To continue in the programme, students must pass the course with a C or better.

Within the SCNS taxonomy, ARR is the Automotive Collision Repair and Refinishing prefix, and the 0000-level number marks this as a PSAV clock-hour course. Daytona State publishes it at 120 clock hours with a $527.38 lab fee — the highest in the programme, reflecting welding consumables and practice panels — offered fall and spring, corequisite ARR0121C. It carries zero college credit.

The phrase "today's high-tech vehicles" is not marketing. A modern vehicle is a mixed-material structure engineered to deform in a controlled sequence, populated with sensors, and assembled with methods that did not exist a generation ago. The trade's central shift is that a technician can no longer decide how to repair something from experience alone — the manufacturer specifies it, and this course is where that discipline is established.

Resources & Tools

• Auto Body Repair Technology (Duffy) — the standard trade text.
• I-CAR (i-car.com) — the industry training organization and the reference on repair procedure; ask whether your programme provides access.
• Manufacturer repair procedure portals — the operative documents; see the OEM flag. OEM1Stop is a free directory.
• ASE (ase.com) — the B3 Non-Structural Analysis and Damage Repair and B4 Structural certifications.
• Welding equipment documentation — squeeze-type resistance spot welding and MIG welding parameters are manufacturer-specified for the material and thickness.
• Adhesive manufacturer technical data — free from 3M, Lord Fusor, and SEM; structural adhesive procedures are exacting.
• Your own hand tools — technicians own theirs, and building the set is an ongoing investment.
• Time on real vehicles — the resource that matters; this trade is learned by doing it.
• OSHA — free guidance on welding, respiratory protection, and shop safety.
• Trade press — Repairer Driven News and similar track procedure and insurer developments closely.

Career Pathways

• Collision repair technician — SOC 49-3021 Automotive Body and Related Repairers; the direct destination.
• Structural repair technician — among the best-paid production roles because fewer technicians qualify for it.
• Heavy collision technician — severe-damage work requiring the most skill.
• OEM-certified technician — manufacturer certification, particularly aluminium and electric vehicles, is the growth area of the trade and commands premiums.
• Estimator and damage appraiser — SOC 13-1032; the common route into salaried, less physical work. See this repository's ARR0021 guide.
• Insurance appraiser and field adjuster.
• Shop lead, production manager, or owner.
• Fleet and heavy truck collision repair.
• Restoration and custom fabrication — Florida's classic car market is substantial.
• Marine repair — a distinctively Florida crossover given the boating industry.

Special Information

⚠⚠ This is a PSAV clock-hour course — and the C-or-better gate is enforced

• A 0000-level SCNS number denotes postsecondary adult vocational instruction, measured in clock hours rather than college credits. This course carries zero college credit.
• Every ARR course states that a C or better is required to continue in or graduate from the programme — a marginal pass in a trade where the work is inspected and warranted is a real problem, and the programme gates on it.
• Attendance is a completion requirement. In a hands-on trade the hours are the skill — you cannot make up bench time you did not take.
• PSAV credit does not transfer as general education. Some Florida colleges award articulated credit toward a related A.S. — ask specifically and get it in writing.
• Financial aid is calculated differently for clock-hour programmes. Ask the financial aid office.
• The credential and the industry certifications are the point, not the transcript.

⚠⚠ Welding quality is a safety matter — and it is tested destructively for a reason

• A weld in a vehicle structure carries crash loads. A weld that looks acceptable and lacks penetration will fail in a collision, and the occupant is the one who finds out.
• Set the machine to the material and thickness. Voltage, wire feed speed, gas flow, and wire type are specified — and manufacturers increasingly specify the weld type and machine settings in the repair procedure itself.
• Practise on coupons of the same material and thickness as the job, and destructively test them. Peeling a test weld apart and seeing whether it pulled a button of parent metal is the only honest verification available.
• Learn the weld types and where each applies — plug welds replacing factory spot welds, butt welds with backing on panel sections, stitch welds, and lap welds. Using the wrong joint type is a procedure violation even when the weld itself is sound.
• Clean to bare metal and use weld-through primer where specified; welding through paint, filler, or corrosion produces porous, weak welds.
• Squeeze-type resistance spot welding replicates the factory process and is increasingly required by manufacturers rather than MIG plug welds — know the difference and when each is specified.
• You cannot MIG weld ultra-high-strength steel structural components in most cases, and heating them destroys their properties permanently. Check the procedure.
• Aluminium requires separate equipment, separate consumables, and a segregated area to avoid galvanic contamination.
• I-CAR welding qualification is a recognized credential and is frequently a shop requirement.

⚠⚠ Follow the OEM repair procedure — this is the industry's governing standard now

• The single biggest change in collision repair over the past two decades is that the manufacturer's published repair procedure governs. It specifies what may be repaired, what must be replaced, where sectioning is permitted, what may be heated, which fasteners are single-use, and what must be recalibrated afterwards.
• Departing from it carries liability for the shop and potentially the technician, and litigation has established that following published procedures is the standard of care.
• Look it up for the specific vehicle, every time. Procedures differ by make, model, model year, and sometimes by build date — experience with a similar vehicle is not a substitute.
• Document that you followed it. Printing or referencing the procedure in the repair file is what supports the estimate and defends the repair.
• OEM1Stop is a free directory of manufacturer repair information portals; most procedures themselves are subscription.
• ⚠ ADAS recalibration is procedure-driven. Cameras, radar, and sensors require recalibration after many operations, and the triggering conditions are specified by the manufacturer — a vehicle returned with an uncalibrated system is a safety and liability problem, not an unfinished job.
• Rule 11 applies with force — this is the fastest-moving part of the trade. Verify current procedures with the manufacturer.

⚠ Repair versus replace is a judgement with a documented basis

• The decision is not primarily economic. It is determined first by whether the manufacturer permits repair of that component, then by material, damage severity, and access — and only then by cost.
• Some components must be replaced regardless of apparent damage severity — many ultra-high-strength and press-hardened structural parts, and any component the manufacturer designates single-use.
• Sectioning is permitted only where specified, at the location and by the method the manufacturer defines. Sectioning at a location of your own choosing is a serious error.
• Single-use fasteners exist — many suspension, structural, and restraint bolts are torque-to-yield and must be replaced. Reusing them is a documented failure mode.
• Parts choice has technical consequences, not just commercial ones. Aftermarket panels can differ in material, thickness, and fit, and some can interfere with sensor operation.
• Document the decision. The estimate and the repair file should record why a component was repaired rather than replaced, citing the procedure.
• When the procedure and the estimate disagree, raise it. Performing a repair you know departs from the manufacturer's procedure because the estimate did not fund it is the position no technician should accept silently — escalate and put it in writing.

⚠⚠ Collision repair safety — the hazards that cause permanent harm

• Airbags and pyrotechnic devices are explosive components. Undeployed airbags, seat belt pretensioners, and battery disconnect procedures must be handled to the manufacturer's procedure, and a mishandled inflator can kill.
• Hybrid and electric vehicles carry lethal voltage. High-voltage systems must be de-energized to the manufacturer's specified procedure with the correct insulated tools and personal protective equipment. This is routine work now, not an exotic case.
• Welding hazards — fume, arc eye, fire, and burns. Galvanized panel coatings produce zinc oxide fume, and vehicle panels are frequently coated. See this repository's PMT0077C and PMT0078C guides.
• Dust and particulates from sanding, including silica from body filler, require respiratory protection and extraction at the tool.
• Adhesives and solvents require ventilation and gloves; structural adhesives in particular have specific handling requirements.
• Isocyanates in refinish materials cause permanent occupational asthma; a supplied-air respirator is the standard of care for spraying. See this repository's ARR0121C guide.
• Stored energy in deformed structure, pulling equipment, springs, and lifts releases suddenly.
• Compressed air, heavy panels, and lifts are the everyday mechanical hazards.
• Hearing protection. Air tools and hammering accumulate a real dose across a career.
• Read the safety data sheet for every product you mix, spray, or bond with.

⚠ The programme runs three parallel tracks as corequisite triples

• Refinishing: ARR0121C → ARR0122C → ARR0123C
• Collision repair: ARR0241C → ARR0242C → ARR0243C, plus ARR0244C
• Unibody and frame: ARR0381C → ARR0382C
• Term one (fall or spring): ARR0121C + ARR0241C + ARR0381C.
• Term two (spring or summer): ARR0122C + ARR0242C + ARR0382C.
• Term three (summer or fall): ARR0123C + ARR0243C + ARR0244C.
• ARR0021 Automotive Collision Estimating (75 hours, summer) completes the programme.
• ⚠ The cross-track prerequisites enforce the cohort. ARR0122C requires ARR0381C and ARR0123C requires ARR0382C — the refinishing sequence is gated by the unibody sequence, so you cannot progress in one track while falling behind in another.
• Nine courses at 120 clock hours plus the 75-hour estimating course is 1,155 clock hours — close to a full-time year, and it should be planned as one.

⚠ I-CAR and ASE are what the industry hires and insures on

• Florida does not license collision repair technicians, so industry certification is the credential that matters — and it matters more here than in most trades, because insurers and manufacturers audit it.
• I-CAR (i-car.com) — the ProLevel pathway leads to Platinum individual recognition and Gold Class shop status, and Gold Class is frequently required for insurer direct repair programme participation.
• ASE (ase.com) — the B-series collision certifications: B2 refinishing, B3 non-structural repair, B4 structural repair, B5 mechanical and electrical, B6 damage analysis and estimating. ASE requires documented work experience in addition to passing, so a course prepares you and does not certify you.
• OEM certification programmes are the growth area. Manufacturers certify shops and technicians for their vehicles — particularly aluminium-bodied and electric models — and certified shops receive referral work that uncertified shops cannot touch.
• Ask your programme which certifications it prepares you for and whether test vouchers are provided.
• Rule 11 applies — certification structures and insurer requirements change; verify with I-CAR and ASE.

⚠ An honest account of the industry — and why Florida is a strong market

• Florida is one of the best collision repair markets in the country. High vehicle density, heavy tourist and rental traffic, year-round driving, an older driving population, and storm and hail damage all generate steady volume, with hurricane-season surges.
• Pay is commonly flat-rate — by the booked hours on a job rather than by the clock. A fast, skilled technician earns well; a slow one does not, and understanding that before accepting a job matters.
• Insurance drives the economics through direct repair programmes that set rates, procedures, and cycle-time expectations. That pressure is the constant background tension of the trade.
• The trade is technically escalating, not declining. Advanced materials, bonded structures, sensors, and electric drivetrains have made the work harder and raised the value of trained technicians.
• There is a genuine technician shortage — the workforce is ageing and replacement has been slow.
• It is physical work — kneeling, overhead work, awkward positions, and heavy panels. Knees, shoulders, backs, and hearing take the load.
• Tools are a real personal cost. Most technicians own their hand tools; ask what the programme provides.
• Progression exists — technician → lead → estimator → manager → owner, and estimating and management are where the better-paid, less physical careers are.

How Florida course levels affect transfer

The first digit of an SCNS number denotes the year of offering, not transferability. Courses at the 1000 and 2000 levels transfer transparently between Florida public institutions, and 3000 to 4000 is unproblematic since both are upper division. The boundary that actually matters is 2000 to 3000, where lower-division credit generally cannot satisfy an upper-division requirement.

ARR0241C is a 120 clock-hour PSAV course carrying zero college credit, with a $527.38 lab fee — the largest in the programme — offered fall and spring with ARR0121C as a corequisite. A C or better is required to continue.

The welding is the part to over-practise. Weld quality is assessed destructively, it is a safety-critical skill, and I-CAR welding qualification is a credential employers ask about by name.
