Automating Nozzle Welding of Pressure Vessel with TIG Technology
In the field of pressure vessel fabrication, most manufacturers have adopted automation for circumferential seam and longitudinal seam welding. These applications are well-suited for automated systems, boosting productivity and consistency. However, one area often neglected in the automation process is the automated welding of pressure vessel nozzles, branch connections, and stub-ins—components that play a critical role in pressure vessels fabrication.
Despite their importance, nozzle welding of pressure vessels is still largely performed manually. This results in high labor costs, inconsistent quality, and slow production—especially when dealing with thick-wall nozzles and multi-pass welds.
The Challenge: Labor-Intensive Nozzle and Component Welding of Pressure Vessels
Nozzles and pipe branches are essential components in any pressure vessel design, enabling fluid entry, exit, and control. Yet in many fabrication workshops, prefabrication of these components, especially thick-wall pipe fittings, remains highly manual.
Challenges include:
- Time-consuming TIG welding for filler passes on thick-wall components
- High dependence on skilled labor for precision welds
- Limited consistency and repeatability
- Difficulties in handling small-batch, high-mix production efficiently
This gap leads to hidden inefficiencies that often go unaddressed in pressure vessel manufacturing workflows.
