From June 17-20, the global welding spectacle—Essen Welding & Cutting Fair—was grandly held in Shanghai. The century-old German welding brand CLOOS and Estun Automation joined forces under the theme "Smart Welding, Smart Future," presenting an intelligent welding showcase featuring cutting-edge processes and integrated solutions.

1. Century-Old Welding Master: CLOOS
CLOOS showcased pioneering technologies including laser-arc hybrid welding, no-teach twin-wire solutions for shipbuilding, and intelligent production line solutions, attracting global industry experts and clients with their exceptional performance and innovation.

▶ ERS No-Teach Twin-Wire Welding for Shipbuilding
Leveraging 30 years of twin-wire expertise and its self-developed ERS No-Teach Programming System, CLOOS delivers efficient welding solutions tailored to shipbuilding.

• Twin-wire welding boosts efficiency by 2-3 times vs. single-wire, with low heat input and minimal deformation.

• ERS supports model-free and model-import modes, featuring intelligent path planning, collision avoidance, and online simulation.

• Integrated with CLOOS’ welding processes and expert database to ensure quality.
  Ideal for thick-plate welding in shipyards, it automates welding for arbitrarily positioned workpieces, optimizes workflows, reduces labor costs, and enhances quality.

▶ Laser-Arc Hybrid Welding Workstation
Combining laser and MIG/MAG technologies for higher speed, lower heat input, and deeper penetration—boosting productivity while maintaining cost-effectiveness.
Widely applied in construction machinery, rail transit, and automotive manufacturing, this technology reduces pre-weld preparation, weld layers, material deformation, and post-processing costs.

▶ Collaborative Welding Workstation

The synergy of premium QINEO welding power sources and high-precision cobots enables efficient small-batch welding with stable quality.

• Supports arc tracking and multi-layer welding.

• Quick programming and compact design save time and space.
  S-series cobots free workers from repetitive tasks, deliver precise/repeatable welds, and support force control for complex applications.

▶ Industrial Automation Line Sandbox
CLOOS’ patented flexible manufacturing system enables fully automated, intelligent, and digital production lines covering loading, welding, and grinding.

• Digital twin system enables real-time monitoring and quality traceability.

• Enhances efficiency, quality, and cost-effectiveness for large-scale smart manufacturing.

2. Welding Versatility: Estun Automation
From precise high-frequency TIG to intelligent thin-plate arc tracking; from aluminum additive manufacturing to deep-penetration welding for mid-thick plates—Estun’s diverse solutions meet high-end manufacturing demands for specialty materials and advanced processes.

▶ Aluminum Additive Manufacturing:
NexT 452 MoTion Automated Welding System
Showcased "Golden Bowl" aluminum additive art: a 20cm aluminum cup built with 180Hz MoTion wire retraction technology, ensuring ultra-stable arcs and satin-smooth seams.Critical for automotive (welding 0.4mm aluminum) and new energy (battery tray production).

▶ High-Frequency TIG Welding:
QuesT 402 AC/DC
Achieves single-sided welding with double-sided formation for aluminum, producing uniform, scaly beads on both sides. Ideal for petrochemical (pressure vessels/pipes), nuclear, and large metal structures requiring high strength/seal integrity.

▶ Low-Current Arc Tracking for Stainless Steel:
StarT 406 Welder + CDD Push-Pull Torch
Enables precise tracking of curved seams at currents as low as 150A, delivering consistent, glossy welds on stainless steel and 3mm carbon steel fuel tanks. Also enhances deposition efficiency for rail transit bogies and deep-penetration welding for excavator arms.

▶ Deep-Penetration Welding for Mid-Thick Carbon Steel:
M500FG
Combines deep-penetration + high-speed welding to revolutionize traditional methods:

• Single-pass full penetration with near-zero spatter.

• Reduces root cleaning by ≥30%.

• Speed high-speed pulse technology boosts efficiency by 40%.
  Proven in excavator booms, power transmission towers, and heavy engineering.

▶ Deep-Penetration Welding for Mid-Thick Aluminum:
NexT 602 Welder + New Push-Pull Torch
Ensures stable wire feeding over 8-meter distances, producing bright, uniform welds with clear scaly patterns. Ideal for shipbuilding, oil/gas pipelines, and rail transit mega-components.

From standalone equipment to turnkey lines, from process breakthroughs to integrated innovation, CLOOS and Estun Automation are leveraging welding to propel China’s high-end intelligent manufacturing. This exhibition reaffirms Estun’s commitment to automation—connecting infinite possibilities through intelligent welding.
