What It Covers

Professional Liability (also called Errors & Omissions or E&O) covers claims alleging negligent acts, errors, or omissions in your professional services — including inspection reports, procedure qualifications, engineering recommendations, consulting advice, quality system assessments, design input, and technical specifications. It covers both defense costs and damages, and it applies even when the claim is groundless, as long as it falls within the policy's scope. Professional Liability policies are typically written on a claims-made basis, meaning the claim must be reported during the policy period — making continuous coverage and careful tail coverage management important.

Why It Matters for Welding Businesses

General Liability specifically and intentionally excludes professional services — meaning that if a client claims your professional judgment caused a loss, your GL policy will not respond. A Certified Welding Inspector, welding engineer, or consulting firm whose professional recommendation, inspection decision, or technical specification is challenged faces exposure that only Professional Liability can address. The costs of defending against a professional negligence claim — even one that is ultimately unfounded — can reach six figures before resolution. For professionals providing written reports, certifications, or engineering deliverables, Professional Liability is the only coverage that protects the core of what they do.

Who Needs It

Certified Welding Inspectors (CWI), Senior Certified Welding Inspectors (SCWI), Certified Welding Engineers (CWEng), independent welding consultants, NDT and inspection firms, testing organizations, Accredited Test Facilities (ATFs), aerospace and defense welding operations providing engineering services, fabrication shops with engineering or design service offerings, and any welding professional whose deliverable is a written report, specification, recommendation, or professional judgment.

Common Triggers

Contract requirements for inspection or consulting services; client contracts requiring E&O coverage as a condition of engagement; professional services agreements; work on projects where your technical judgment is a core deliverable; completing inspection reports or welding procedure qualifications.

Welding Industry Examples

• A CWI issues a written inspection report approving a structural weld — the weld later fails, and the client alleges the inspector missed a visible defect.

• A welding engineer's procedure specification is alleged to have contributed to a structural failure due to an error in preheat requirements.

• A welding consultant's process change recommendation is linked to a production quality crisis at a manufacturing client.

• A testing organization's NDT report is challenged after a component fails in aerospace service — the client claims the report contained an incorrect interpretation.

• An inspection firm certifies a weld procedure qualification that is later found to be improperly documented — the client faces a code compliance issue and claims against the firm.

• A Senior CWI providing expert testimony is named in a lawsuit alleging their report in a prior project was negligent.
