Welding Service

Welding is a critical process for creating robust, complex metal structures, from industrial roller assemblies to custom steel beams and heavy-duty components. At AstraRoll, we specialize in precision welding tailored to the strict demands of roller production, ensuring every joint delivers the structural integrity required for long-term, high-load operation.

Our workshop is equipped with advanced TIG/MIG/MAG welders, spot welding systems, and high-precision Panasonic welding robots, combining manual craftsmanship and automated efficiency for consistent, high-quality results.

Welding Expertise & Material Compatibility

We offer versatile welding solutions compatible with a full range of industrial materials:

• Weldable Materials: Mild steel, stainless steel, aluminum, and common industrial alloys
• Welding Methods: TIG/MAG welding, spot welding, robotic welding, and specialized processes tailored to your material and load requirements

Our certified technicians select the optimal welding method for each application, whether for precision rollers or heavy-duty mining components, ensuring perfect fusion and long-term reliability.

Comprehensive Post-Weld Solutions

To maximize strength and durability, we provide a full suite of post-weld treatments and surface coatings:

• Post-Weld Processing: Stress-relief heat treatment (annealing), shot blasting, and primary paint
• Surface Coating Options: Zinc plating, hot galvanizing, powder coating, Teflon/PTFE, tungsten carbide, rubber coating, and more
• Large-Scale Capacity: Support for components up to 11,000mm length × 5,000mm width, ideal for large roller assemblies and custom structures

Rigorous Quality Assurance

Quality control is integrated into every stage, with non-destructive testing (NDT) as a final safeguard:

• NDT Inspection: Ultrasonic flaw detection (UT), magnetic particle inspection (MT/MPI), and penetrant testing (PT)
• Full Coverage: Every critical weld is thoroughly inspected to eliminate hidden defects, ensuring zero quality risks before delivery

Unlike general fabricators, we specialize in the unique demands of roller manufacturing, combining certified welding expertise with deep knowledge of roller design and load dynamics. Our hybrid manual + robotic approach delivers consistent precision for high-volume production and custom projects alike, while end-to-end post-weld treatment and rigorous NDT ensure our welds stand up to the harshest industrial environments.

AstraRoll’s welding service combines advanced technology, certified expertise, and strict quality control to deliver high-strength, precision-welded rollers and components. From initial welding to final finishing and inspection, we ensure every product meets the highest performance and durability standards for your industrial operations.
