Welder Certification Tests

Prepare with confidence: this section offers practical welder certification tests for self-checks and prep for NAKS and in-house exams. Topics include materials and weldability, joint types, parameters (current, voltage, travel speed), edge prep, heat treatment, defects and NDT (visual, UT, RT, PT/MT), job safety, PPE and fire prevention, tolerances, electrode/filler classifications, plus specifics of SMAW, GMAW/MIG-MAG, GTAW/TIG, hardfacing, and pipeline/structural welding. Our welder certification tests reflect real question sets and production standards. Choose “training” or “exam” mode, difficulty by process and materials, track progress, and generate reports for supervisors and QC. Hints, error reviews, and explanations close gaps, while timers and attempt limits simulate real conditions. Welder certification tests work on desktop and mobile for initial certification, renewals, and transitioning to new processes—so you prove your skills on the first try and improve weld quality.
