TIANYU Full-Welded Electric Worm Gear WCB Carbon Steel Gate Valve: The Sturdy Choice for Industrial Fluid Control

I. Core Analysis of Full-Welded Technology

(A) Advantages of Welding Processes

• Automated TIG Welding is used for root pass welding of critical valve parts, precisely controlling heat input to ensure fusion quality. It forms a uniform, dense weld root to avoid defects like porosity and incomplete penetration.
• SAW Welding is applied for filling and capping, featuring high efficiency, beautiful weld formation, and large penetration depth, ensuring high-strength and excellent mechanical properties of the welds.

(B) Welding Quality Control

• Pre-Welding Treatment: WCB carbon steel base materials undergo rigorous pretreatment, including surface grinding and cleaning to remove oil, rust, and impurities, ensuring cleanliness of welding joints. Environmental temperature and humidity are precisely controlled.
• Real-Time Monitoring: Weld tracking systems monitor weld position and parameters (current, voltage, speed) in real time, automatically adjusting to ensure uniform weld formation.
• Nondestructive Testing: All welds undergo 100% UT (Ultrasonic Testing) and RT (Radiographic Testing):
  • UT detects internal defects like cracks and slag inclusions with high sensitivity.
  • RT visually displays defect shape, size, and position, ensuring compliance with ASME BPVC standards.
