MODULE Module 1 — Drawings, Joints & TOTAL QUESTIONS 25 Questions
Preparation for Welding
SUBJECT AREAS Weld Symbols · Joint Types · Cutting · FORMAT Multiple Choice — Select the Single Best
Gouging · Positions Answer
MODULE 1 EXAMINATION INSTRUCTIONS
▸ Select the single best answer for each question based on CWB Welding Inspector Level 1 Module 1 content.
▸ Content covers: engineering drawings (orthographic projections, dimension lines, perspective drawings), weld symbols and
joint types (fillet, groove, lap, tee, corner), cutting processes (oxy-fuel, plasma arc, water jet, shears, air carbon arc gouging),
grinding grit sizes, welding positions (1G through 6G), and joint design principles (minimum weld metal, double U-groove).
▸ Key reference: Weld symbols on the TOP of the reference line apply to the OTHER side of the joint. Fillet welds are used for LAP,
TEE, and CORNER joints.
SECTION I — DRAWINGS, WELD SYMBOLS, JOINTS & CUTTING Questions 1 –
PROCESSES 25
1. How many dimensions are required to evaluate a fillet weld's size?
A. 1 — only the leg length.
B. 2 — leg length and throat.
C. 3 — both legs and the throat.
D. 4 — both legs, throat, and face width.
CORRECT ANSWER C — 3 dimensions (both legs and the throat).
RATIONALE A fillet weld requires THREE dimensions for complete size evaluation: BOTH LEG LENGTHS and the THROAT. A
weld symbol shown on the TOP of the reference line applies to the OTHER SIDE of the joint (the side opposite
the arrow). Dimension lines are generally placed so the drawing may be read from the BOTTOM and RIGHT-
HAND EDGE of the sheet. The maximum number of principal views in an orthographic projection is SIX (front,
back, top, bottom, left side, right side). The designation 3G refers to the VERTICAL position groove weld.
