CWI study: turn a welding symbol into a learning checklist
Recognizing a familiar weld-type symbol is a useful start. Explaining the complete welding symbol takes more practice. Use the notebook exercise below to separate what you can already explain from the part you need to study next, then check your understanding with another lesson example.
Put welding symbols in your CWI study plan
AWS lists welding symbols among the subjects in the CWI Part A fundamentals examination. Its program distinguishes Part A fundamentals, Part B practical and Part C code book examinations. Symbol practice belongs within a broader preparation plan.
AWS A2.4 covers communication of welding, brazing and nondestructive examination information through symbols. For this exercise, use the example and reference assigned in your lesson; record the reference edition in your notes.

Separate the weld symbol from the welding symbol
A weld symbol identifies a weld type. The welding symbol is the complete assembled callout containing the information supplied for that weld. Naming the weld type does not explain every element of the callout.
NDTAcademy’s Reading and Interpreting Welding Symbols lesson develops this vocabulary distinction. AWS’s symbols-course outline also separates weld types from topics such as arrows, reference lines and supplementary information. Use those as headings for questions you need to resolve in your assigned lesson.

Replace a vague note with a specific study task
Consider this fictional learner’s note: “I recognized the weld symbol, so I understand the drawing.” The note records one success but does not show what the learner can explain about the rest of the callout.
A more useful version is: “I can name the weld type. I can point to the reference line and arrow, but I cannot yet explain the extra mark in this lesson example. I will find its name and purpose in the assigned reference, write the page or section, and explain it again without copying the answer.”
This revised note produces a clear next task. It also preserves the skill the learner has already demonstrated. The example is an original study exercise, not an official examination item or an instruction for making a weld.
| Study task | Evidence to put in your notebook | Next action if incomplete |
|---|---|---|
| Name | The term for the element you are studying. | Find the term in the lesson. |
| Explain | One sentence describing its role in that example. | Revisit the explanation and ask a precise question. |
| Locate | The assigned reference, edition and page or section. | Find the supporting passage before treating the answer as checked. |
| Try again | Your explanation of the corresponding element in another example. | Compare the two explanations and revise the uncertain part. |
Check what your answer demonstrates
Use the distinction above to answer these three questions before reading the review.
- You correctly name the weld type. Have you explained the complete welding symbol?
- Your notes say, “Study symbols again.” What would make that instruction more useful?
- You can repeat a worked answer word for word. What could you do next to check your understanding?
Review your answers and choose the next lesson
First: no. You have identified the weld type, which is one part of the complete callout. Your next explanation should address the element the exercise asks about, using the assigned reference.
Second: name the element and the task. For example: “Find the name of the extra mark in example 2, explain its role and record the reference.” That gives you something specific to finish.
Third: try another assigned example and explain your reasoning in your own words. Then compare it with the lesson’s explanation. A different example can reveal where you remembered an answer without understanding the distinction.
Keep this notebook focused on learning. It does not determine weld dimensions, authorize fabrication or establish inspection acceptance. Apply the instructions and requirements supplied for the actual task through the appropriate training and supervision.
Continue with CWI D1.1 preparation
NDTAcademy’s CWI AWS D1.1 track includes Weld Joints, Weld Types, and Weld Nomenclature, followed by Reading and Interpreting Welding Symbols. If vocabulary is the gap, start with the first lesson. If you can name the parts but struggle to explain a callout, use the checklist with the symbols lesson.
Review the public practice-exam page and the full course outline when planning your study. The separate WPS, PQR and welder-qualification article addresses records; it answers a different question from this symbol exercise.
Exam preparation does not award AWS CWI certification. Check AWS’s current eligibility and examination requirements when planning an application. Employers can use the team-training page to discuss a shared learning plan.
