CW Certified Welder exam-day guide
CW Certified Welder · Prepare for the day ahead.
Your checklist
Valid government-issued photo ID
Bring the original ID you registered with (driver's license, passport, or state ID). Name must match your registration exactly. Acceptable ID forms and whether a second form is required vary by provider - confirm with the provider before test day.
Admission or scheduling confirmation
Printed or digital copy of your test authorization, candidate number, and reporting time/location. Keep it with your ID so check-in is quick.
Welding helmet with correct shade lens
Inspect the headgear, shell, and lens for cracks or pitting. Bring spare cover lenses and a spare shade lens in case of spatter damage mid-test.
Safety glasses
Clear safety glasses for grinding and inspection, plus a shaded pair if you will be doing any torch work. Bring a spare pair.
Flame-resistant clothing and leathers
FR or cotton work shirt and pants with no cuffs or frayed edges, leather jacket or sleeves, leather apron, and gauntlets. Avoid synthetic fabrics.
Leather work boots
Closed-toe, sturdy leather boots with intact soles and laces. Confirm with the provider whether metatarsal guards or specific footwear standards are required.
Welding gloves, at least two pairs
A broken-in primary pair plus a dry spare. Wet or burned-through gloves are a common cause of a failed root pass and an avoidable safety hazard.
Hand tools: chipping hammer, wire brush, slag hammer, files
Bring more than one wire brush and keep brushes dedicated to a single base metal if stainless or aluminum is involved, to avoid cross-contamination.
Measuring and layout tools
Tape measure, soapstone or marker, adjustable wrench, tip cleaners, and any gauge the applicable code calls for (fillet weld gauge, undercut gauge). Confirm which gauges the provider supplies.
Consumables and base metal
Many facilities supply electrodes, filler, and test plates; others require you to bring them. Confirm in writing from the provider what is furnished versus what you must supply.
Read the applicable WPS and acceptance criteria in advance
Know the process, position, joint design, current range, polarity, and pass sequence you will be tested on, and know the visual acceptance limits in the referenced code.
Respirator and personal comfort items
If you wear a respirator, confirm the provider's policy on fit testing and whether it may be worn in the booth. Bring water and a snack if the schedule is long; confirm whether food is allowed in the test area.
Plan the day
Re-read the candidate information bulletin and the WPS. Confirm reporting time, address, parking, and what the facility supplies versus what you must bring. Write the answers down so you are not guessing on test day.
Do two or three practice welds in the exact process, position, and joint configuration you will be tested on. Practice the full sequence including fit-up, tacking, cleaning between passes, and finishing - not just the arc time.
Inspect all PPE: helmet shell and headgear, lens shade, gloves, jacket, sleeves, boots. Replace anything cracked, burned through, or worn thin now rather than the morning of the test.
Protect your sleep and avoid alcohol. Fatigue shows up first in arc starts and bead placement, which is exactly where visual inspection is least forgiving.
Pack the toolbox completely and lay out clothing and PPE by the door. Do a final inventory against your checklist and confirm nothing is missing.
Confirm your transportation plan and set two alarms. Calculate the arrival time so you are on site well before the reporting time, with margin for traffic and check-in.
Review the WPS parameters and the visual acceptance criteria one last time. Stop practicing - last-minute technique changes do more harm than good.
Eat a real meal and hydrate. Bring water. Test sessions are often long and the booth is hot.
Arrive early for check-in with ID and confirmation in hand. Allow time for toolbox inspection if the provider requires it.
Listen to the full briefing before touching anything. Note the booth number, time limits, where to place finished test pieces, and how to summon the proctor.
Inspect the machine, leads, ground clamp, and gas flow (if applicable) before striking an arc. Report any equipment fault to the proctor immediately rather than compensating for it yourself.
Set parameters within the WPS range and record them if the test requires it. Clean each pass thoroughly and check fit-up and distortion as you go.
Watch the clock per weld, not just overall. Leave time to complete, clean, and mark each test piece and to shut down the booth properly.
Identify and submit your test pieces exactly as instructed before leaving the booth. Confirm with the proctor that your pieces have been logged.
Rules to check
Bring photo ID that matches your registration and present it at check-in. Accepted ID forms and any second-form requirement vary by provider - confirm with the provider rather than assuming.
Wear the required PPE whenever you are in the welding area. A proctor may stop or remove a candidate who is not in compliance, and this can end the test.
Work only in your assigned booth on your assigned test pieces. Do not touch another candidate's work, tools, or machine, and do not accept help or coaching from anyone.
Bring only approved tools and materials. Expect your toolbox to be inspected, and confirm in advance which power tools, grinders, and consumables are permitted in the booth.
Ask the provider in advance how breaks are handled, whether the clock stops during a break, and whether you may leave the test area. Do not assume either way.
If equipment fails or a test piece is damaged through no fault of your own, stop and notify the proctor immediately. Do not attempt repairs or substitutions on your own.
Scoring is based on the examination and testing required by the applicable code or standard - typically visual inspection and, where specified, destructive testing against the acceptance criteria in that code. Ask the provider to confirm which code and which tests apply to your certification.
Confirm the provider's policy on retests, late arrival, and disqualification before test day. These policies are set by the testing organization and are not negotiable at the booth.
