What is Large Weldment Fabrication?

Large weldment fabrication can be defined as robust metal assemblies that are created by welding multiple individual components together for a variety of end applications. Some examples of large weldments fabricated at Custom Engineering include construction equipment, soleplates, skids, foundations, machine housings, large base plates for equipment, and other components used in heavy equipment or other mining machinery. These large weldments are extremely heavy and represent a unique fabrication challenge, even for the most experienced technicians. These products typically require the use of up to ½” to 2” thick steel plate to help withstand the tremendous weight and forces present during end applications. Custom Engineering has even used steel plates up to 8” thick for unique specialty applications that require reliable performance in the most demanding industries.

How Custom Engineering Fabricates Large Weldments

Custom Engineering has spent years integrating modernized technology, robust equipment, and countless certifications and registrations into its large weldment fabrication offerings. This combination of machinery and experience has positioned Custom Engineering as a leading U.S. supplier of heavy industrial metal fabrication. The spacious 200,000 square-foot facility not only can house large weldments but also has a specialized flooring system that ensures accurate fit-up of large weldments and the assorted heavy steel plates. Furthermore, this system creates a square and level working surface that is critical to Custom’s ability to produce and hold exceptionally close tolerances.

Custom Engineering is well equipped with large table capacity planer mills and CNCs to machine the individual components of large weldments up to 15’ x 60’. Once machined, Custom Engineering employs decades of combined experience of its welding team and over 180 documented welding procedures, including fully robotic, semi-automatic, and manual welding. Each project for large weldments and fabrication with heavy lifting capacity is precisely placed to ensure each weld meets specific tolerances and will hold the intended angular dimensions.

The Difference Heavy-Lifting Capacity Makes in Large Weldment Fabrication

Heavy lifting capability is a core engineering advantage in large weldment fabrication that directly impacts precision, fit-up, and production efficiency. Custom Engineering’s integrated crane system and other heavy-lifting equipment enable safer, faster, and more accurate handling of oversized assemblies while helping to reduce costs and safety risks for OEMs.

  • In-house crane systems and heavy-lifting equipment provide controlled and accurate positioning of components and finished weldments weighing up to 160,000 pounds, minimizing distortion and improving dimensional accuracy.
  • The ability to lift and manipulate these robust assemblies allows welding and other machining operations to be completed on the same fixture surface, reducing the possibility of handling errors that result in rework.
  • Heavy-weight handling equipment improves joint alignment, weld penetration consistency, and the final structural integrity of welds across thick-plates or challenging alloys.
  • Precision lifting capacity accelerates production efficiency for large weldment fabrication and addresses possible bottlenecks in the workflow before they arise.
  • This assortment of heavy-lifting equipment allows Custom Engineering to tackle large OEM contracts and more complex fabrication projects in the aerospace, defense, energy, construction, and heavy-equipment markets.
