"Vincent had an opening and started the job right away. The job presented some problems because the gate was made of thin inch and one half metal tubing that was difficult to weld. Vincent’s practical abilities with the welding and some inventive engineering not only got the job done but did it in a timely manner. I would highly recommend TM Steel for any project they would be willing to do."

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.

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.

To maintain custom or fabricated metal structures and extend their lifespan and appearance, perform regular cleaning, apply rust prevention treatments, and use protective coatings.

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.

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
