Use this practice set to reinforce the knowledge behind the hands-on AWQT: aluminum oxide control, dedicated tools, push-technique pulse GMAW, ER4043 vs ER5356 filler selection, 100% argon shielding, OEM repair procedure authority, and AWS D8.14-style acceptance criteria. The official credential is earned by depositing acceptable aluminum welds at an I-CAR testing facility, not by passing a written multiple-choice exam.

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.
