Product Introducton

AW400 – Programmable Welding Power Source

●Siemens PLC control – Built with a Siemens PLC system and imported key components for superior reliability and durability in continuous operation.

●One-touch programming – 7" touchscreen auto-generates welding parameters by simply entering pipe diameter and wall thickness. Reduces dependency on highly skilled welders.

●Wide current range – 5A–400A output covers everything from thin-wall tubes to heavy-wall pipes. One unit, multiple applications.

●Universal compatibility – Fully compatible with all our weld heads (sealed tube-to-tube, open tube-to-tube, tube-to-sheet, etc.) for flexible system configuration.

●Advanced welding features – Arc length tracking and oscillation support multi-pass and filler wire welding, ensuring smooth, high-quality weld seams.

●Large program storage – Stores 70–100 welding programs for quick job changeover and consistent batch production.

The Pipe Flange 500 is a fully automatic large-diameter pipe flange welding equipment independently developed by Wuxi Bohan. It is suitable for circumferential welding of pipes and flanges with a maximum pipe diameter of 500mm. Paired with Bohan's AW400 series programmable welding power supply, it is specifically designed for the prefabrication of pipelines in the chemical, oil and gas, and clean industries, enabling automated circumferential welding of pipes to flat-face/welded neck flanges.

Product Advantage

1. Large Diameter Compatibility: Covers pipes from DN50 to DN500, compatible with stainless steel, carbon steel, titanium alloy, and other materials; orbital pipe flange welding machine suitable for both flat welding and high-neck flanges.

2. Digital Precision Control: 7-inch bilingual (Chinese and English) touchscreen, capable of storing hundreds of welding process parameters for one-click retrieval; current, speed, gas, and water cooling are synchronously controlled throughout the process, ensuring high weld consistency and stable flaw detection pass rate.

3. High Efficiency and Automation : Frequency conversion rotation of the workpiece eliminates vibration; the welding torch supports oscillating filling, achieving one-time forming of internal and external corner welds; welding efficiency is increased by more than 50% compared to manual welding, suitable for batch pipeline prefabrication.

4. Stable and Durable Design: Built-in circulating water cooling in the welding head allows for continuous high-load operation; key drive and electrical control components use imported parts, featuring overcurrent, overheat, and fault self-diagnosis protection, adaptable to both factory prefabrication and on-site construction scenarios.

5. Complete welding traceability: Supports full recording of welding parameters, with optional parameter printing function, meeting the quality traceability standards of the pharmaceutical, nuclear power, and pressure vessel industries.
