Laser Welding Production Line for Stainless Steel Tube Optical Fiber Unit
Description
The laser welding production line for stainless steel tube optical fiber unit is used to produce stainless steel tube optical fiber secondary coating units for applications such as OPGW, OPPC,submarine optical cables, etc.
The production line uses laser welding technology to form precision stainless steel tubes from steel strips through forming, welding, and drawing. At the same time, optical fibers and gel are filled into the tubes, resulting in a stainless steel tube optical fiber unit that combines structural strength with transmission performance.
2. Equipment Features
High-precision laser welding keeps the heat-affected zone extremely small, greatly reducing welding deformation and residual stress. This ensures the dimensional accuracy and shape stability of the stainless steel tube.
At the same time, it achieves deep penetration welding, giving the weld high strength and excellent sealing with few defects like porosity or cracks.
Plus, the weld surface is smooth and aesthetic, requiring no post-weld grinding — saving production costs.
