Product Overview

Bortech Corporation is pleased to introduce its Model 613-L Welding Lathe. The Welding Lathe applies a consistent weld on the entire outer diameter of any round part, with no stopping and starting until the workpiece is complete. Compared to hand welding, which leaves unevenly stressed weld beads due to frequent stopping and starting, distortion of the workpiece is minimized and the quality of the weld is increased. As an added bonus, weld time is also significantly reduced.

Bortech has designed, manufactured and sold automated bore welding machines for 15 years. The Model 613-L Welding Lathe uses the same, proven, “stepping” indexing technology that Bortech pioneered in its flagship line of BoreWelders. The “stepping” method holds the torch stationary while the workpiece rotates a full 360 ° , applying the weld in a single plane. The torch then “steps”, and applies another 360 ° weld in the next parallel plane, repeating the process until the workpiece is completed. Complete coverage is achieved, while independent control over the welding parameters (including step size) enables precise control of the weld deposit.

Features

• Single start and stop provides a consistent weld
• “Stepping” technology allows precision bead placement and complete weld coverage, from the first bead to the last
• Independently adjustable parameters allow the user to control the bead thickness (weld deposition)
• Travel carriage can be disengaged for rapid re-positioning
• Three positioning adjustments:
• Vertical (for stick-out and multi-pass welding)
• Horizontal (for bead offset from centerline)
• Angular (for arc weld angle)
• Steady-rests are provided for longer workpieces (one steady-rest standard, additional quantities and sizes are optional)
• All steel construction, 26” wide x 42” high
