Materials We Weld

Industrial Welding for Tool Steels, Alloys & Manufacturing Materials

Warren Industrial Welding Co., Inc. provides industrial welding services for a wide range of ferrous and non-ferrous metals used in tooling, dies, molds, and critical manufacturing components. Our team understands how different materials respond to heat, stress, and welding processes—allowing us to restore damaged parts, repair tooling, and complete fabrication work that performs in demanding industrial environments.


From hardened tool steels to specialty alloys and lightweight metals, we select the right welding method to maintain strength, control distortion, and extend component life.

Ferrous & Non-Ferrous Materials 

We regularly weld common and specialty metals used in manufacturing, tooling, and industrial equipment.

Common Materials We Weld Include:

  • Aluminum
  • Brass & copper
  • Carbon steel & mild steel
  • Stainless steel
  • Cast iron & cast steel
  • Hot-rolled steel
  • Carbide
  • Magnesium
  • Kirksite tooling material
  • AMPCO® alloys
  • Stellite
  • Titanium
  • High Speed
  • Mild Steel

These materials are commonly used in tooling, machine components, and industrial equipment requiring strong, accurate repair.

Specialty Alloys & High-Performance Metals

We weld high-performance alloys used in demanding applications where strength, heat resistance, and durability are critical. Includes:

  • Hastelloy
  • Inconel
  • Heat-resistant alloys
  • Wear-resistant alloys
  • Specialty industrial metals (evaluated per application)

These materials require controlled welding techniques to prevent cracking, distortion, and material failure.

Material Expertise That Protects Your Parts

Welding industrial materials isn’t just about joining metal—it’s about preserving strength, structure, and performance. Many components require controlled heat input, proper filler selection, and precise technique to avoid damage.

Our experience allows us to:

  • Restore worn or cracked components
  • Maintain material integrity
  • Reduce the risk of distortion or failure
  • Extend the life of tooling and equipment

Not Sure What Material You Have?

If you're unsure whether your part can be welded or repaired, we can help. Our team will evaluate the material and recommend the best solution for your application.
