"Light Speed Welding is a gift from God. Matt got right back to me by phone and text. I sent him pix of the job. He gave me a fair price. It was a complex job and included welding three small pieces to a chassis. He did it perfectly w/o any complaining. Tough job, but he made it look easy. Talented. Recommend highly."

Their team was knowledgeable, efficient, and thorough in both the assessment and execution. The final result is not only structurally sound but also compliant with safety regulations—giving us peace of mind and a polished finish. I highly recommend them for any code-related repairs or upgrades. Excellent welding!"

"After giving me an estimate for the work and the above price agreed upon, Mr. Donovan did the work in a very professional manner.  He and his worker stayed until the job was fully completed even though earlier we had a thunderstorm.  I would recommend Eastern Welding Company for any welding and wrought iron work to be done."

Welding questions, answered by experts

Yes, but you’ll need reliable steel-cutting tools and safety gear to get started. Shipping containers are typically around ¾ inch thick, so it’s entirely possible to cut through them, but experience and the right equipment are very important. When possible, try to get a container as close to the size you want it as possible.

Costs depend on unit complexity, labor, wall mounting needs, and additional accessories like floating shelves.

The cost to weld aluminum averages about $14 to $22 per pound. The type of metal factors into the overall cost of any welding project due to the cost of the materials and the expertise required to work with it. Some of the most common metals used by welders include:

  • Magnesium alloy: $7–$16 per pound

  • Low-carbon steel: $11–$12 per pound

  • Stainless steel: $13–$15 per pound

  • Copper/brass: $24–$29 per pound

  • Cast iron: $38–$79 per pound

  • Titanium: $60–$85 per pound

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. 

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.
