The Cantilever Pipe Automatic Welding Machine (Chuck-Type) for Pipe Spool Fabrication Line

Introduction

The Cantilever Pipe Automatic Welding Machine is a specialized equipment designed for prefabricating pipe spools with multiple welds. Its unique chuck-type clamping system makes it particularly suitable for welding short pipe segments where space for traditional clamping is limited. The system typically consists of a chuck-type welding driver, a mobile roller support cart, and a traveling cantilever welding carriage, allowing for continuous, multi-pass welding of longer pipe sections.

Key Specifications & Parameters

Features & Advantages

• Stable Chuck Clamping: The pipe ends are secured by a chuck mechanism, which prevents axial movement ("chattering") during the welding process, ensuring consistency.

• Versatile Application: It is designed to handle various welding configurations common in prefabrication shops, such as straight pipe-to-pipe, pipe-to-fitting, and short pipe-to-fitting joints.

• High-Quality Welds: The machine utilizes advanced techniques like QSPT root pass welding and is capable of MIG welding for root, fill, and cap passes, achieving high-quality welds. The resulting welds can meet stringent quality standards, including radiographic (RT) or ultrasonic (UT) inspection with over 98% qualification rate for Grade I or II welds.

• Efficient Continuous Welding: The integrated system of the driver, support cart, and welding carriage enables efficient continuous welding of long pipe segments with multiple welds.

Application Directions

This machine is engineered for pipe prefabrication workshops across various industries. It is ideal for projects requiring high-volume production of standardized pipe spools, such as those for industrial plant construction, power generation facilities, and shipbuilding, where consistent, high-quality welds are critical.
