In Portland, Maine, projects involving aluminum and stainless steel require a specialist's touch.

At NRK Welding, we are the experts in precision TIG and MIG welding for both aluminum and stainless steel.

Specialized TIG & MIG Welding for Superior Results

Welding aluminum and stainless steel is a specialty that requires specific techniques and equipment. We utilize both TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding processes to achieve the best possible outcome for your project.



  • TIG Welding: The preferred method for aluminum and stainless steel, TIG welding produces clean, precise, and high-quality welds. This process is ideal for thin-gauge metals and applications where aesthetics are a top priority, such as architectural features and custom artwork.
  • MIG Welding: MIG welding offers a faster and more efficient solution for thicker materials and projects where speed is essential. Our team is skilled in both processes, allowing us to select the perfect technique for the unique demands of your job.

The Benefits of Aluminum & Stainless Steel

Clients choose these metals for a variety of reasons:


  • Corrosion Resistance: Both materials are highly resistant to rust and corrosion, making them perfect for marine environments and outdoor applications in Southern Maine's coastal climate.
  • Strength-to-Weight Ratio: Aluminum is an incredibly strong, yet lightweight metal, making it ideal for everything from truck bodies to custom fixtures.
  • Aesthetic Appeal: Stainless steel provides a clean, modern, and professional look that is sought after in commercial kitchens, medical facilities, and high-end residential projects.

Frequently Asked Questions about Aluminum & Stainless Welding

  • Can you weld aluminum on-site?

    Yes, our mobile welding units are fully equipped for on-site TIG and MIG welding of aluminum and stainless steel. This is especially useful for marine repairs or large commercial equipment that cannot be moved to our shop.


  • Do you offer welding for marine projects?

    Absolutely. We have extensive experience with marine welding, including repairs on boat hulls, pontoons, railings, and other components, ensuring they are resistant to saltwater corrosion.


  • What is the difference between TIG and MIG welding for these materials?

    TIG welding is known for its precise, clean welds, making it ideal for thin materials and fine details. MIG welding is faster and more efficient, typically used for thicker materials and larger projects where a strong, quick weld is needed.
