BOS Master - Clause-Level Inspection Training
Make the right call under pressure — the same way you'll have to on the CWI exam.

BOS Master trains you to read the code, classify the weld, and make a defensible decision in real time — so you stop guessing and start thinking like a working inspector.

​

​​The real problem

Most candidates don't fail CWI Exams because they're “bad at welding.”

They fail because, under a clock, they can't turn a messy weld and a code book into a clean, defensible decision.

• They freeze between “this looks bad” and “I don’t see a table that clearly says reject.”
• They misclassify fusion failures as profile issues — or over-reject ugly but acceptable welds.
• They can’t explain why their call matches the code when someone pushes back.

​

BOS Master fixes one thing: your ability to go from evidence → classification → clause → decision under exam pressure and in the field.

If any of this sounds familiar

• You second-guess your VT calls as soon as someone questions you.
• You “know” the code but struggle to use it when time is short.
• You’re worried Part B will expose gaps in your decision process.

 

You don’t need more random questions. You need a decision system.

Real Inspection. Real Code. Real Decisions.

ClauseBot doesn’t “fail everything.” It makes the correct call — both ways — under pressure.

 

Scenario #1 — Fusion Failure (Reject)

CJP groove weld on structural steel. Linear indication along the groove face. No UT report. Thickness not clearly stated. Foreman says “sign it off — we need to ship.”

What Most Inspectors Do
Hesitate. Misclassify it as undercut. Or pass it because nothing is clearly measured and production is behind.

What the Code Actually Requires
AWS D1.1 — complete fusion shall exist in CJP groove welds. Any indication of incomplete fusion is rejectable, regardless of thickness, loading, or schedule pressure.

ClauseBot Decision
REJECT — classified as incomplete fusion, a fusion defect, not a profile issue. No measurement or “we always ship these” history overrides this requirement.

 

Scenario #2 — Ugly but Acceptable (Profile)

Fillet/PJP weld on A572 structural steel. Visible undercut along the weld toe. Measured depth: 1/32″ (≈1 mm). Length: 3″ over a 16″ weld. Statically loaded member. WPS and welder qualifications verified.

What Most Inspectors Do
Reject it because it looks bad. Overcall the defect. Force unnecessary grinding and rework.

What the Code Actually Requires
AWS D1.1 — undercut is allowed within specific depth and length limits for this thickness and loading. At 1/32″ deep over a short segment, this weld is within allowable undercut limits.

ClauseBot Decision
ACCEPT — classified as undercut, not fusion failure. Within table limits. Appearance alone does not override the code.

 

This is the difference between guessing… and knowing exactly what the code requires.

This is the exact decision skill that determines whether you pass or fail the CWI exam — and whether you make the right call in the field.

 

Inside BOS Master

Train your brain to run the same decision loop every time.

BOS Master isn’t “more videos” or a stack of PDFs. It’s a focused set of drills that force you to practice the exact moves ClauseBot makes in those scenarios.

• Classify the indication correctly before you touch a table.
• Identify the governing standard stack (project spec → engineer → AWS).
• Pull the right clause/table and translate it into plain language.
• Document a decision that can survive a hostile challenge.

 

You leave with a reusable inspection script you can run on the CWI exam and on real jobs.

What you get

• Core BOS walkthrough: how to think like a working inspector.
• Scenario drills (fusion vs profile vs porosity vs “nothing there”).
• Clause-mapping templates you can reuse on any code excerpt.
• Decision log framework you can turn into your own “field notebook.”

 

Your investment

One decision skill that pays for itself the first time you use it.

Whether it’s passing CWI on the first attempt or preventing one bad call in the field, BOS Master pays for itself the moment you stop guessing.

​

If you work through the BOS drills and don’t feel more confident making code-backed decisions, contact us within 14 days and we’ll make it right.

 

Who this is for

• CWI candidates who don’t want Part B to be a coin flip.
• Inspectors who are tired of arguing by opinion instead of clause.
• Leads and supervisors who need consistent, defensible calls from their team.

 

Who this is not for

• If you just want more random practice questions.
• If you’re not willing to slow down and actually run the decision process.

 

You don’t need another book. You need a decision system.

The difference between passing and failing — and between being “the picky inspector” and the one people actually trust — is your ability to make the right call under pressure.

 

BOS Master gives you that ability, in a form you can use on the exam and on the job.
