Weld repair in Manchester, NH, for welds that didn't pass inspection and for welds that cracked or broke in service. The bad weld comes out with carbon arc gouging, so nothing faulty stays under the new one. Then we weld it back to the detail, AWS-certified to D1.1 and D1.8. Call (603) 660-2011 or send the inspection report.
A weld repair removes faulty weld metal down to sound steel and welds the joint again to the same detail. Then it gets inspected again. It's never a cover pass over the old bead, because the defect would still sit inside.
It usually starts with a report. The inspector lists the welds that don't meet the detail, with a note on what's wrong with each. On a steel job the general contractor calls in that inspector. How the inspection runs is on the page on structural welding, so here we start where the report ends.
Often that inspector is AWS-certified for the job. The AWS page on what a Certified Welding Inspector does lists what it takes. Three exams, a vision test, and the right mix of education and experience. So the report in your hand comes from someone who knows the code well.
To start a repair, we need the report, the drawings with the weld details, the location and your schedule. The report tells us which welds failed and why, down to the defect the inspector found in each. That decides whether a weld comes out completely or only needs building up, so it shapes the whole estimate.
A rejected weld usually comes down to one of a handful of defects. Each has its own look, and its own reason it can't stay.
Not every defect means the whole weld comes out. An undersized or short weld can often be built up to size. Porosity, cracks and lack of fusion are different, though, because the bad metal has to go first. The report and the detail decide which repair a weld gets.
A repair follows a set order, because skipping a step just hides the defect.
We don't promise how a re-inspection turns out, because that call isn't ours to make. On a repair, certified welding done right means each rejected weld is rebuilt to the detail from sound metal.
Not every bad weld shows up on a report. Welds on trailers, railings, gates and brackets can crack in service, usually where the load works back and forth. That's called fatigue, and it builds one cycle at a time until the weld gives.
The rule is the same. The crack gets ground out to sound metal and welded again, because welding over a crack only buries it.
Booms and machine frames follow their own procedure, and the page on heavy equipment repair covers it. That page also covers whether a part is worth fixing at all.
“Excellent welding company! The quality of the work was outstanding, and they were professional, reliable, and easy to work with from start to finish. They paid close attention to detail, completed the job in a timely manner, and made sure everything was done right. I’m very happy with the results and would highly recommend them to anyone looking for high quality welding work.”
Not on anything that carries a load. Epoxy glues to the surface, while a weld melts the steel and fuses it into one piece. On a trailer, a bracket or a frame, the crack still has to come out and be welded. Epoxy has its uses on parts that hold nothing up, but a broken weld under load isn't one of them.
Not as the final word. The welder checks his own repair, and AWS D1.1 also has an inspection by the welding contractor itself. On a steel job, though, the general contractor brings in the inspector, the same as for the original welds. That inspector's report is the one the job goes by.
It depends on the welds, so there's no set price per repair. How many failed, how long and deep they are, and the access all count. The estimate is free. A long repair list gets a written estimate, while a few welds get a number on the phone.
Call (603) 660-2011 and tell us how many welds were rejected and when the next trade is due. Then send the report and weld details, so the price comes from what the inspector actually wrote.
