1Which industry-standard specification is most commonly referenced by I-CAR for evaluating aluminum collision-repair welds in AWQT preparation?

A.AWS D1.1 Structural Welding Code-Steel

B.AWS D8.14 Specification for Automotive Weld Quality-Arc Welding of Aluminum

C.ASME Section IX Boiler and Pressure Vessel Code

D.API 1104 Welding of Pipelines and Related Facilities

Explanation: AWS D8.14 (Specification for Automotive Weld Quality-Arc Welding of Aluminum) is the AWS standard that covers aluminum arc-welding quality for automotive body, frame, and supporting structural members. I-CAR aluminum welding training and the AWQT use D8.14-style acceptance concepts.

2Aluminum oxide forms on bare aluminum surfaces and presents a significant welding obstacle. Approximately what is its melting point compared with the underlying aluminum base metal?

A.About 600 deg F, well below the base metal melting point

B.About the same as the base metal, roughly 1,200 deg F

C.About 3,700 deg F, roughly three times higher than the base metal

D.It does not have a true melting point because it sublimates at room temperature

Explanation: The tenacious aluminum oxide layer melts near 3,700 deg F while the underlying aluminum base metal melts near 1,200 deg F. The huge gap means heat will melt the base metal long before the oxide layer is disturbed, so the oxide must be mechanically removed before welding.

3Why is a stainless-steel brush (not a carbon-steel brush) used to remove aluminum oxide immediately before welding?

A.Stainless steel brushes are softer than the aluminum

B.Carbon-steel bristles contaminate the aluminum with iron and create corrosion sites

C.Stainless steel brushes generate static electricity to attract oxide particles

D.Carbon-steel bristles are too soft to remove the oxide layer

Explanation: Carbon-steel bristles leave iron particles embedded in the aluminum, which become galvanic-corrosion initiation sites and contaminate the weld. A clean, dedicated stainless-steel wire brush avoids ferrous contamination and is the I-CAR-recommended tool.

4Which shielding gas is the I-CAR standard for aluminum GMAW pulse welding in collision repair?

A.75% argon / 25% CO2

B.100% pure argon

C.100% CO2

D.98% argon / 2% oxygen

Explanation: Aluminum GMAW pulse welding uses 100% pure argon shielding gas. CO2- or O2-containing gases cause oxidation and weld defects on aluminum. Helium blends exist for thick-section work, but the typical collision-repair AWQT setup is 100% argon.

5Which gun-angle technique is required by I-CAR for aluminum GMAW pulse welding?

A.Pull technique with the gun angled backward over the puddle

B.Push technique with the gun angled forward toward the leading edge

C.Straight-up technique with no travel angle

D.Either push or pull as long as travel speed is controlled

Explanation: Aluminum GMAW is welded with the push technique only. Pushing keeps the argon shielding ahead of the puddle and prevents oxide and atmospheric contamination from being drawn into the weld. Pulling leaves contamination behind and is not acceptable for aluminum.

6How long is the I-CAR Aluminum Welding Qualification Test (AWQT) credential valid before recertification is required?

A.1 year

B.3 years

C.5 years

D.Lifetime once issued

Explanation: I-CAR welding qualifications, including the AWQT, are valid for three years. Successful retesting on the same hands-on standard is required to maintain the credential.

7Which mainstream vehicle line drove industry-wide adoption of aluminum body-repair training when its body became aluminum-intensive in the 2015 model year?

A.Toyota Camry

B.Chevrolet Silverado

C.Ford F-150

D.Honda Civic

Explanation: The 2015 Ford F-150 moved to a high-strength, aluminum-alloy body, dramatically expanding the number of shops needing aluminum welding capability. This was a major driver of I-CAR AWQT enrollment and the establishment of dedicated aluminum repair areas.

8Which welding process is the focus of the I-CAR AWQT skills test for aluminum body repair?

A.Shielded Metal Arc Welding (SMAW)

B.Gas Metal Arc Welding (GMAW) in pulse mode

C.Submerged Arc Welding (SAW)

D.Flux Cored Arc Welding (FCAW) self-shielded

Explanation: The AWQT is based on aluminum GMAW in pulse-synergic mode. Pulse GMAW reduces heat input and spatter and gives the control needed for thin automotive aluminum.

9Why does I-CAR require aluminum repair work to be performed in a separated, dedicated area with its own tools and equipment?

A.To reduce noise levels in the shop

B.To prevent steel-particle and other ferrous cross-contamination of aluminum

C.Because aluminum welding requires a Class 1 cleanroom

D.Because aluminum dust is explosive only outside the body shop

Explanation: Aluminum welds are sensitive to ferrous contamination. Steel dust from grinding or sanding nearby steel parts will embed in aluminum surfaces and cause corrosion and weld defects. A dedicated aluminum work area with separated, dedicated tools (grinders, brushes, drills, sanders, blankets, vacuum) is therefore required.

10Which two filler-wire alloys are most commonly used in aluminum collision repair?

A.ER70S-6 and ER80S-D2

B.ER4043 and ER5356

C.ER308L and ER316L

D.E6010 and E7018

Explanation: ER4043 (silicon-based) and ER5356 (magnesium-based) are the two principal aluminum filler wires used for collision repair. Wire selection depends on the base alloy series being welded and the target mechanical and corrosion properties.

About the I-CAR AWQT Exam

The I-CAR Aluminum Welding Qualification Test (AWQT) is the recognized collision-repair welder qualification for aluminum-bodied vehicles. It follows the WCA01 (technical), WCA02 (hands-on practice), and WCA03 (skills test) sequence and verifies push-only aluminum GMAW pulse welding with pure argon and aluminum filler. AWQT-qualified technicians repair aluminum-intensive vehicles including the Ford F-150 (since 2015), Jaguar XJ, Tesla Model S and X, BMW 5/6/7 Series, and Audi A8 (Audi Space Frame). The credential aligns with AWS D8.14 (Specification for Automotive Weld Quality - Arc Welding of Aluminum) acceptance concepts.

Assessment

AWQT candidates complete a butt joint with backing, a lap-joint fillet, and a plug weld in vertical and overhead positions on aluminum coupons (typically 1 mm and 2.5 mm) using pulse-synergic GMAW with 100% argon and ER4043 or ER5356 filler. All welds must pass visual inspection and destructive testing.

Time Limit

About 40 minutes equipment familiarization, then about 20 minutes per timed position for the test welds.

Passing Score

Visual and destructive acceptance per AWQT criteria aligned with AWS D8.14-style automotive aluminum requirements; no MCQ passing score on the official test.

I-CAR AWQT Study Tips from Top Performers

1Practice the WCA02 hands-on sequence on the same machine, gas, and filler you will use at WCA03. Cross-machine transfer is harder than steel welders expect.

2Treat aluminum as a separate workflow: dedicated bay, tools, consumables, and PPE. Cross-contamination breaks otherwise good welds.

3Clean and brush immediately before welding. Aluminum oxide regrows in minutes, so timing matters.

4Use push technique with a 5-15 degree forward lead and verify shielding flow at the cup, not only at the regulator.

5Inspect every practice coupon visually first, then peel or bend test. Train yourself to catch porosity, cold lap, undercut, and crater cracks before the real test.

6Practice crater fill or back-stepping terminations - aluminum craters shrink and crack if left unfilled.

7Always treat the OEM repair procedure for the specific VIN as the authoritative document; general I-CAR guidance reinforces, not replaces, OEM-specific instructions.

Frequently Asked Questions

Is the I-CAR AWQT a multiple-choice test?

No. The AWQT is a hands-on welder qualification administered through I-CAR's WCA03 skills test. Candidates produce aluminum test welds (butt with backing, lap fillet, plug) in vertical and overhead positions, which are visually inspected and destructively tested. These 100 MCQs are original practice questions for supporting knowledge.

How long is the AWQT credential valid?

Three years. Recertification requires retaking the AWQT-style hands-on welding test under current I-CAR policy.

Which welding process is used on the AWQT?

Aluminum GMAW in pulse-synergic mode, with 100% pure argon shielding, push technique only, and ER4043 or ER5356 aluminum filler wire.

Why is the push technique mandatory for aluminum?

Pushing keeps the argon shield ahead of the leading edge of the puddle and prevents oxide and atmospheric contamination from being drawn into the weld. Pulling on aluminum traps contamination and is not accepted.

What is the difference between ER4043 and ER5356 filler wire?

ER4043 is silicon-based (about 5% Si) - good fluidity, lower hot-cracking sensitivity on many base alloys, and better anodize color match. ER5356 is magnesium-based (about 5% Mg) - higher strength, preferred for 5xxx-5xxx and many 5xxx-6xxx joints, but typically a darker anodized color.

Why must aluminum work use separated, dedicated tools?

Ferrous particles from steel work embed in aluminum and become corrosion and weld-defect sources. I-CAR requires dedicated grinders, brushes, drill bits, sanders, blankets, and vacuums, and ideally a separated bay or curtain, to control cross-contamination.

Which OEMs drive demand for AWQT-qualified technicians?

Ford (F-150 since 2015), Tesla (Model S and X), Jaguar Land Rover (XJ and others), BMW (5/6/7 Series), and Audi (A8 Aluminum Space Frame) are leading sources of aluminum collision work. Many maintain approved-shop networks requiring trained aluminum welders.

What is the AWS reference standard for aluminum collision welding?

AWS D8.14 (Specification for Automotive Weld Quality - Arc Welding of Aluminum) covers minimum standards for arc welding of aluminum body, frame, space frame, cradle, and suspension components. I-CAR AWQT acceptance concepts are aligned with D8.14.
