Specialty Welding & Fabrication

Precision Fusion. Uncompromising Structural Integrity.

The integrity of any mechanical system is only as strong as its welds. At Endur Contractors LLC, we provide high-performance welding and fabrication services that meet the rigorous demands of industrial, commercial, and high-purity environments. Our certified welders combine advanced technical skill with state-of-the-art equipment to deliver joints that are as durable as they are precise.

Advanced Metal Welding | TIG & MIG

We offer versatile metal joining solutions tailored to the specific metallurgical requirements of your project.


  • TIG (Tungsten Inert Gas): Our preferred method for high-precision, aesthetic, and contaminant-free welds. It is ideal for stainless steel, aluminum, and thin-gauge materials used in pharmaceutical and food-grade applications.
  • MIG (Metal Inert Gas): Utilized for high-efficiency, high-strength joins in heavy-duty commercial and industrial carbon steel applications.

Structural Welding

Safety and load-bearing reliability are the foundations of our structural welding services. Whether fabricating custom supports, equipment skids, or facility infrastructure, our team adheres to strict AWS (American Welding Society) standards.


We ensure every structural component is engineered to withstand the operational stresses of your specific environment.

 Precision Orbital Welding

For mission-critical piping in the semiconductor, biotech, and pharmaceutical sectors, we provide Orbital Welding services. This automated process ensures 100% repeatable, full-penetration welds with a smooth internal profile.


By eliminating human error and minimizing the Heat Affected Zone (HAZ), we deliver leak-free, ultra-pure piping systems that meet the most demanding inspection criteria.

High-Performance Plastic Welding

Corrosive environments and chemical distribution systems require specialized thermoplastic solutions. Endur specializes in advanced plastic welding techniques, including Hot Air Welding and fusion, to create seamless, leak-proof bonds.


We work with a comprehensive range of industrial plastics, including:

  • PVC & CPVC: For reliable plumbing and light chemical transport.
  • Polyethylene (HDPE): Ideal for durable, flexible underground and industrial piping.
  • Polypropylene: High-strength solutions for chemical and laboratory applications.
  • PVDF (Kynar): High-purity, chemical-resistant welding for the most aggressive process environments.

Material Versatility

Our expertise extends across a diverse spectrum of materials, ensuring the right welding process is matched to the right application:



  • Stainless Steel (304, 316L)
  • Carbon Steel & Specialized Alloys
  • Aluminum
  • Thermoplastics & Fluoropolymers
