Portable Tank Girth Welding Tractor with Welding Power Source

Product Specification

Product Description:
The Portable Tank Girth & Longitudinal Rail Welding Cart is an innovative, self-contained system designed to automate and significantly improve the quality and efficiency of welding horizontal (girth) and vertical (longitudinal) seams on large cylindrical tanks, vessels, and pipes. This compact, track-mounted solution provides a stable platform for welding torches (MIG/MAG, TIG, SAW, FCAW), ensuring precise, consistent travel along the weld path. Its defining feature is portability – the entire system (cart, drive unit, control panel, and modular tracks) is easily transported and rapidly set up directly on the tank surface itself, eliminating the need for heavy, fixed-position welding manipulators or complex scaffolding.

Key Specifications (Example):

Distinctive Features:

1. True Portability: Lightweight, modular design for easy transport and on-site setup directly on the tank.

2. Dual-Axis Capability: Effortlessly welds both horizontal (girth) seams around the tank circumference and vertical (longitudinal) seams along its height.

3. Modular Track System: Rails connect quickly to form any required length for girth welds or height for longitudinal welds. Secure tank mounting.

4. Precise Speed Control: Digital variable speed control ensures consistent travel speed critical for high-quality welds.

5. Stable Platform: Rigid rail system minimizes vibration and wandering, ensuring torch stability.

6. Simple Operation: Intuitive controls, easy torch mounting, and quick track setup minimize training time.

Key Benefits:

• Dramatically Increased Welding Speed: Automates travel, significantly faster than manual welding.

• Superior Weld Quality & Consistency: Eliminates human variability; produces uniform, defect-free seams (reduced porosity, undercut, lack of fusion).

• Enhanced Worker Safety: Reduces need for welders to work at height or in confined spaces for long periods; improves ergonomics.

• Reduced Labor Costs: One operator can manage multiple carts or perform other tasks while welding.

• Lower Skill Dependency: Less reliance on highly skilled manual welders for consistent results.

• Reduced Rework & Scrap: Consistent quality minimizes costly repairs and material waste.

• Rapid Setup & Deployment: Saves significant time compared to erecting scaffolding or positioning large manipulators.

• Versatility: Handles various tank sizes and seam types (girth & longitudinal).

Primary Applications:

• Field construction and repair of storage tanks (oil, water, chemicals, LNG).

• Fabrication of pressure vessels, silos, and large-diameter piping.

• Power plant boiler and stack fabrication/repair.

• Shipbuilding (tank sections).

• Water/wastewater treatment tank fabrication & maintenance.

• Wind turbine tower section welding (girth seams).

• General heavy fabrication involving large cylindrical structures.
