"Working with Ace Mobile Welding was honestly shocking in the best way possible. They actually answered the phone, showed up when they said they would, and finished the job without disappearing for three business weeks. In construction terms, that’s basically a miracle. The quality of work was top tier. Everything was clean, solid, and done right the first time. You can tell these guys actually care about their craftsmanship instead of just hitting everything with spray paint and saying “she’ll hold.” The crew stayed professional, communicated clearly, and kept the work area organized the entire time. No chaos, no guessing games, and no one standing around pretending to look busy while holding a tape measure. Good people, honest work, and the kind of company you call again instead of warning your friends about. Definitely recommend Ace Mobile Welding to anyone who wants the job done right without the usual contractor headache."

"I needed creative additions welded to old exercise equipment. Work was done fast and as hoped for. Mr. Seymore then painted over the welds, and the equipment was ready for use in a few hours. I'd call for them again for welding projects."

"I was very pleased with the metal work that Yolex Richardson completed for me. He was very pleasant to deal with and extremely knowledgable about welding and metalwork. He returned my calls promptly and completed the work in a very timely fashion. I needed to have an iron trellis repaired that was supporting my porch roof and I am very satisfied with the excellent results. We had set a date for the projject to be done, and he followed through as promised. I believe he was honest in his assessment and gave me a fair price for the work completed. He also does other exterior work, i.e., replace or rebuild porch beds and tile work, and I plan to hire him for future projects. I definitely recommend his business to anyone who needs welding/ironwork done."

Welding questions, answered by experts

Cutting rectangular ductwork requires careful measurements and the right technique. Use a measuring tape and pencil to mark the cutting lines accurately. Tin snips are excellent for straight cuts on smaller ducts. For more extensive or thicker rectangular ducts, a reciprocating saw with a metal-cutting blade is effective. 

Ensure the duct is well-supported and secure while cutting to prevent wobbling and maintain precision. After cutting, use a metal file to smooth any sharp edges, ensuring safety during installation. 

Since water heaters are primarily made of metal, they’re commonly accepted by scrap yards and collectors. Don’t expect to fetch a high price, though—water heaters are mostly steel and aluminum, which aren’t high-value metals. Some components are made of more valuable metals, like brass and copper, but they’re a small portion of the heater and won’t affect the price much.

The best thing to cut metal pipe is a durable pipe cutter that is made for metal. You may want to measure the diameter of the pipes before purchasing a pipe cutter to ensure it will be able to cut your metal pipes. Opt for a heavy-duty option to cut through metal like steel or cast iron.

You should not do your own welding unless you have the proper training and experience. Most home electrical systems can only handle MIG welding, which creates weaker bonds than TIG welding and won’t work on certain metals or metal thicknesses. Both welding forms usually require the use of shielding gas, which can be dangerous to store at home. Additionally, welding machines create temperatures of over 3,000 degrees, and the sparks can blind you if you don’t have the proper equipment. As such, it’s usually better to hire a professional welder for your welding projects.

It will likely take an experienced pro less than an hour to install a ground rod, which is another reason why letting them handle the job is such a good idea. Safety concerns aside, it would likely take you much longer to install a ground rod if you decided to take this one as a DIY job.
