Being a welding inspector you have certain responsibilities that need to be performed on a regular basis, whether it is in a plant, fab shop, or out on the ROW. To be a welding inspector you will go through a lot of training but also years of experience to get your certified welding inspector certificate. Everyone experiences and paths to get to that level are different, like all things in life everyone sees things from different point views. To give everyone a baseline for work, I made an easy list of items I check on when I am doing a welding inspection. This is by no means an absolute list, more of a starting point, things can be added or may not apply. As you read this, you will notice that there is a lot of etc… and this is to show there are more items that can be added at your discretion. Hope this helps

Pre-Welding Inspections
Safety Requirements: Ensure all welding related activities are conducted in accordance with all local municipal, state and federal safety regulation, in addition to complying with all company defined safety rules and regulations.

Documentation review:
• Verify specification, including year of issuance and any revisions
• Inspect plans, including any revisions, and verify compliance
• Verify welding and inspection equipment calibrations
• Verify welding materials (base metals, filler wire, consumable electrodes, etc.…)

Welding equipment review:
• Inspect welding equipment, including welding machines, regulators, cables, etc.…
• Welding materials:
• Inspect all base and consumable materials (steel rods, sheet metal, pipes, filler wire, consumable electrodes, etc.…)

Preparation and set-up:
• Confirm correct cutting method relative to projects and materials
• Confirm correct angles, joints and gaps (bevel angle, lap joint, root gap, etc.…)
• Confirm pre-welding set-up (materials properly aligned, clamps in place, equipment in correct position)
• Confirm proper welding machine settings, amperage and heat

During the Welding Process

Monitor:
• Welding site for inclement weather (if applicable)
• Heating values to maintain proper bonding heat
• Distortion controls to maintain balance and prevent blow-thru
• Consumptions of electrodes, filler wire or gas
• Welding process, including voltage, amperage, travel speed, etc.…
• Verifying proper temperature controls between welding passes
• Verify any other compliance issue dictated by the individual project requirements

Post Welding Review
• Conduct visual inspection
• Inspect and confirm NDT (radiographic and ultrasonic inspections) requirements (method, operator qualifications, proper execution)
• Identity any necessary repairs or corrections via visual inspection or NDT review
• Conduct post weld heat treatment to verify proper heating method and temperature recording
• Conduct final hydrostatic test procedure

Repairs and Corrections
• Evaluate all original procedure to verify and confirm validity
• Approval of all pre-welding procedures outlined above
• Monitor repair process as outline in the monitoring section outlined above
• Re-inspect the repair area and confirm repair completion via visual and NDT inspection
