Ask your broker for online access, then issue your own welding certificate in about a minute, free, any hour. A certificate of insurance is the one page summary of your policies, limits, and dates, and Morrow clients print their own at no charge. Changes that need an endorsement (a change added to your policy, usually one extra page) still go through the broker. Who this is for: mobile welders, fabricators, and structural and pipe welding shops.
The short version
- Your broker issues certificates. Some let you issue your own online, free, in a minute.
- Plants and refineries ask for the highest limits in the trades, often several million dollars.
- Fire is the claim. Your policy may only cover cutting and welding if you follow written fire rules.
- A signed permit before you strike an arc, and someone watching for smoke after, protect your claim.
- Naming a customer on the certificate is fast. Adding them to the policy is a broker change.
How do I issue my own certificate in about a minute?
- Sign in to the certificate tool your broker set up for you.
- Pick the policies, usually general liability, workers comp, auto, and umbrella.
- Type in the plant, contractor, or equipment owner who asked.
- Add the site address and the purchase order number.
- Send it, or upload it to the screening service the plant uses.
You are printing proof of coverage you already carry. See what documents you need before a job starts.
Who asks a welding business for a certificate?
| Who is asking | What they want |
|---|---|
| A plant or factory | High limits, their company named on your policy, and often a screening service that scores your paperwork before you badge in |
| A general contractor | Limits, dates, workers comp, and coverage that continues after the job |
| A trucking or equipment owner | Proof you carry liability before you weld on their trailer or bucket. Know what that policy does: it pays for a fire that spreads to their shop, not for the trailer or bucket itself. Damage to the part you work on, and to property in your care, is left out of a standard policy |
| A property owner or manager | Their company named, and a certificate before any torch arrives |
What is a hot work permit and why does my insurer care?
Hot work means cutting, welding, grinding, or anything that throws sparks. A permit is a short form the site signs before you strike an arc. It says who checked the area, what was moved, and who stands fire watch.
A fire watch is a person who stays and looks for smoke after the work stops. Many plants require at least 30 minutes and plenty require an hour, so price that labor in.
| Common site rule | What it means for you |
|---|---|
| Clear or cover anything that can burn within about 35 feet | Move it, wet it, or use fire blankets. Note it on the permit |
| An extinguisher within reach | Charged, tagged, and yours |
| Fire watch during the work and after it | A second person on the clock |
| Permit signed by the site before you start | Keep a copy. It is the first thing anyone asks for after a fire |
Insurers care because many contractor policies limit fire claims from cutting and welding unless those steps were followed. Some leave out hot work away from your own shop. Ask your broker to read that page to you.
What limits do industrial customers ask for?
Higher than most trades see. These are common asks, not a promise about your contract.
| Line | Small commercial and farm work | Plant, refinery, and utility work |
|---|---|---|
| General liability | $1,000,000 for one incident, $2,000,000 for the year | The same, plus a per project limit on larger contracts, a yearly limit that starts over for that one contract. It is added to the liability policy itself. No umbrella supplies one, and not every insurer will add it |
| Umbrella | $1,000,000, sometimes none | $5,000,000 to $10,000,000 |
| Workers comp | What your state requires | The same, plus employers liability, the part that pays if an employee sues you. That is three limits, not one: commonly $100,000 each accident, $500,000 policy limit for disease, $100,000 each employee for disease. Contracts often ask for $500,000 or $1,000,000 on all three. The state fund policies in North Dakota, Ohio, Washington, and Wyoming carry none of it, so you buy stop gap coverage separately |
| Commercial auto | $1,000,000 | $1,000,000, sometimes $2,000,000 for site vehicles |
| Pollution | Rare | Asked for on tank, pipeline, and process work |
Big umbrella limits take time to place, so start early. See how to get a $5 million umbrella and how umbrella shows on a certificate.
What holds up a welding certificate?
- The umbrella is short. The most common turn away at a plant gate.
- The purchase order number is missing. Screening services match paperwork to a job file.
- The plant is not on your policy. The certificate alone gives them nothing.
- Your policy limits hot work. Find that out in the office, not at 6 a.m. at a gate.
What this looks like in real life
Illustrative example. It is typical of what we see and is not a promise of how any specific situation would be handled.
The setup: A four person mobile welding outfit in Texas is called to a food plant for a shutdown weekend. The purchase order asks for $1,000,000 of liability, a $5,000,000 umbrella, and the plant named on the liability policy.
What went wrong: The crew arrives at 5 a.m. Saturday. The screening service shows the umbrella at $1,000,000 because nobody updated the certificate after the higher limit was bought in March.
What it cost: The crew waited four hours for the office to open, then lost the first shift of a two shift job, roughly $6,800 in billable time and a shutdown window nobody could repeat.
The fix: The coverage was already in place. Only the paper was stale. With online access the owner reissues a correct certificate in about a minute.
Frequently asked questions
Q: How can I get a free, instant certificate of insurance for my welding business?
Ask your broker for online certificate access. You type in the site, the purchase order number, and the work, then send it in about a minute. Morrow clients do this free, at any hour.
Q: Why do plants want such high limits from a welder?
Because a fire in a plant can cost far more than the job you are doing. Limits of $5,000,000 or $10,000,000 are common asks, and they are usually met with an umbrella above your other policies.
Q: Does my policy cover a fire I start while cutting?
It depends on your wording. Many contractor policies cover it only if the written fire rules were followed, and some leave out hot work away from your own shop. Have your broker check before you bid plant work.
Q: Do I need a permit for welding at a farm or a small shop?
The site may not require one, but the habit protects you. A signed sheet showing what you moved and who watched is the best evidence you have if a fire is blamed on your work.
Q: Can I weld on a customer's equipment without naming them on my policy?
You can, unless the contract says otherwise, and most industrial customers require it. Either way, your liability policy does not pay to fix the trailer or bucket you were welding on. Ask your broker about a separate policy on property in your care.
Q: How fast can I fix a certificate that shows the wrong umbrella limit?
About a minute if the higher limit is already on your policy and you can issue your own. If it is not, buying more coverage can take a day to two weeks, so ask early.
