TIG orbital welding machine SX322 series

automaticfor pipesintegrated

Overview
The SX322 is a prefabrication orbital welding machine designed for large-diameter tube fabrication where repeatable joint geometry and controlled weld profile are required. It performs orbital TIG welding by fusion or fusion + wire on carbon steels, stainless steels and exotic alloys and is driven by SAXX power sources. The SX322 is optimised for workshop prefabrication and can be reconfigured quickly for orbital cutting or beveling to support complete tube processing workflows.

Key data

• TUBE OD RANGE: 5.563″–12.750″ (141–328 mm)
• COOLING: Air-cooled (SX322-A) or Water-cooled (SX322-E)
• FUNCTIONS: Orbital TIG welding by fusion or fusion + wire; reconfigurable for orbital cutting and beveling

Product Advantages

• Orbital TIG welding (fusion or fusion + wire) for consistent, repeatable welds
• Axial electrode and tube adjustment to achieve precise joint alignment
• Micrometric arc-gap adjustment without special tooling for fine weld control
• Mechanical OD tracking to compensate tube ovalization and maintain constant electrode-to-tube distance
• Concentric clamping system with stainless steel clamping jaws to minimise tube distortion and contamination
• Automatic orbital rotation for uniform penetration and weld appearance
• Multi-process capability (welding, cutting, beveling) with fast changeover using two setting screws
• Compatible with SAXX power sources for automated welding cycles
• Suitable for workshop prefabrication to reduce on-site welding time and installation risk
