"• The coupler on the trailer was bent. • The trailer itself was in good condition. • The owner called Alex Ortega for assistance. • Alex reviewed the situation and I purchased a new coupler from Harbor Freight. • Alex spent six hours welding the new coupler onto the trailer. • The job was done very well, and the owner was very pleased. • The owner recommends Alex Ortega for any welding jobs. • The owner uses the trailer to transport their trike and move items from stores. • The owner notes that paying for delivery from stores can add up, making a trailer a worthwhile investment."

"We are extremely happy with the metal railings at our home. The workmanship is excellent, the railings are steady, beautifully finished, and exactly what we wanted. The team was professional. They completed the installation neatly and on time. The new railings have greatly improved both the appearance and safety of our home. We highly recommend them to anyone looking for quality custom metalwork."

"James was exceptionally professional and polite and did an outstanding job on the rails that he installed in my house with both the backyard and the front. He’s a perfectionist and I will hire him and re-hire him over and over and recommend him over and over. Very humble and a very soulful human being. I give him 10 stars not five. Thank you, James for the wonderful professional job. :)"

Welding FAQs, 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. 

The average cost for a welding project is about $300, with typical costs ranging from $125 to $490. However, prices can be as low as $125 for very small jobs or exceed $1,200 for large or complex projects. Welders typically charge an hourly rate between $65 and $150, depending on their experience, and many charge a minimum fee to cover overhead and travel expenses. The total cost is influenced by several factors, including labor, the cost of materials like metal rods and shielding gas, the type of metal being welded, the project's size and complexity, and your geographic location. For a precise quote, it's best to ask a local welder for an estimate based on your specific project.

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

Some welding projects, such as repairing pipes or fences, require travel, whereas others, like furniture repair, do not necessarily require the welder to come to you. Travel and overhead factor into the overall cost of your welding project. Some of the most common welding projects include:

  • Metal furniture repair: $35–$100

  • Pipe repair: $200–$1,000

  • Small gates: $550–$750

  • Fencing: $1,200–$1,800

  • Fabricated sheet metal welding: $750–$2,500

Welders use a variety of methods in their trade. Different types of welding are better suited for different purposes and contexts. For example, stick welding is a versatile form suitable for most metals and alloys. The most common types of welding include:

  • Stick welding: $100–$1,000

  • Metal Inert Gas (MIG) welding: $250 and up

  • Tungsten Inert Gas (TIG) welding: $250 and up

  • Gas welding: $150 and up

  • Forge welding: $15–$25 per hour
