MTTC Welding Trade Test study guide
MTTC Welding Trade Test · Work through your exam, one topic at a time.
The MTTC Welding Trade Test is a Michigan teacher-certification assessment for individuals who want to teach welding in a secondary or postsecondary career and technical education setting. It is aimed at candidates who already hold trade-level welding skill and now need to demonstrate that they can teach it: the exam blends hands-on trade knowledge with pedagogy, safety, and shop-management judgment. The MTTC Welding Trade Test study guide has 9 sections and about 2,103 words.
01Welding Safety, Health, and Environmental Practices
Candidates must know the fire triangle and hot-work permit system, the classes of fire and extinguisher selection (A, B, C, D, K), and the safe storage and handling of compressed gas cylinders (upright, capped, secured, separated by fuel type, oxygen and fuel gas at least 20 ft apart or by a 5-ft noncombustible barrier). Ventilation requirements, fume composition by process (manganese, hexavalent chromium from stainless, zinc from galvanized), and personal protective equipment selection - shade lens numbers per amperage, leathers, respirators - are heavily tested.
303 words, about 2 min02Welding Processes and Equipment
You must compare SMAW, GMAW (short-circuit, globular, spray, pulsed), FCAW (self-shielded vs. gas-shielded), GTAW (AC vs.
233 words, about 1 min03Blueprint Reading, Symbols, and Layout
Candidates must read welding symbols per AWS A2.4: the reference line, arrow, tail, groove and fillet symbols, size and length placement, the distinction between arrow side and other side, all-around and field-weld flags, and supplementary contour and finish symbols. You should interpret orthographic and isometric views, first-angle vs.
262 words, about 1 min04Metallurgy and Materials Science
Understand the iron-carbon diagram, the effect of carbon content on hardenability and weldability, and the phases ferrite, austenite, cementite, martensite, and pearlite. Know heat-treatment basics - annealing, normalizing, quenching, tempering, stress relief - and how cooling rate, preheat, and interpass temperature control microstructure.
216 words, about 1 min05Joint Design, Fit-Up, and Weld Preparation
Know the five basic joints (butt, lap, tee, corner, edge) and the groove types (V, bevel, U, J, square) with their included angles, root openings, root faces, and land. Understand the terminology of a weld cross-section: root, face, toe, leg, throat, reinforcement, and effective throat.
233 words, about 1 min06Welding Procedures, Codes, and Standards
You must know the role of a Welding Procedure Specification (WPS) and Procedure Qualification Record (PQR), and how welder performance qualification (WPQ) differs from procedure qualification. Study AWS D1.1 structural steel essentials: prequalified joints, essential variables, qualification tests, and inspection acceptance criteria.
202 words, about 1 min07Inspection, Testing, and Quality Control
Know nondestructive examination methods - visual (VT), liquid penetrant (PT), magnetic particle (MT), ultrasonic (UT), and radiographic (RT) - with their capabilities and limitations. Visual inspection is the most common and catches surface defects; PT finds surface-breaking defects on nonporous materials; MT works only on ferromagnetic materials; UT detects internal flaws and requires access to one side; RT reveals internal porosity and inclusions but poses radiation hazards.
214 words, about 1 min08Thermal Cutting, Brazing, Soldering, and Related Processes
Study oxyfuel cutting principles: the preheat flame brings steel to ignition temperature (about 1,000–1,200 °F) and the oxygen jet oxidizes and blows away metal. Know neutral, oxidizing, and carburizing flames and their uses; oxyfuel cutting works on steel but not on aluminum or stainless without a powder or plasma assist.
230 words, about 1 min09Shop Management, Career Readiness, and Instructional Practice
Candidates should understand shop organization, job planning, cost estimating (labor, material, consumables, overhead), inventory and consumable control, and preventive equipment maintenance. Safety management includes hazard communication, SDS use, and recordkeeping.
