The Welding Lathe is designed for high-precision welding and consolidation of quartz rods and tubes used in optical fiber manufacturing. The system ensures uniform joint quality and maintains structural integrity during high-temperature welding.
The vertical configuration allows controlled traction and alignment, supporting both short and long rods while maintaining diameter consistency and minimizing defects.
Optimized for industrial production, the system offers:
Precise welding of rods and tubes
Direct-drive or continuous traction methods
Mechanical and electrical synchronization options
The Welding Lathe operates by heating and consolidating quartz rods or tubes under controlled vertical alignment. This process ensures a strong, uniform bond and maintains material quality for subsequent processing steps.
Input rods or tubes with diameters ranging from 90–130 mm can be processed, producing output rods of 50–80 mm in diameter and lengths up to 9 meters. The system accommodates different product sizes and requirements, providing flexibility for various optical fiber applications.
Traction is applied via direct-drive or continuous drawing methods, with synchronization options available for precise control. This ensures smooth movement and consistent welding along the rod’s axis.
The vertical multi-tier frame structure provides mechanical stability and supports long-duration operation at high temperatures. Operator controls allow adjustment of speed, traction, and welding parameters for repeatable results.
Integration with upstream sintering and deposition equipment or downstream elongation systems is straightforward, forming part of a complete quartz rod production line.
