Precision Welding, Guaranteed Quality – Unveiling the Welding Process of JX Filtration’s Large-Scale Equipment
In the field of industrial manufacturing, the welding quality of large-scale equipment directly impacts the product's service life, safety, and stability. JX Filtration understands this deeply, which is why every weld seam in our manufacturing process strictly adheres to high-standard procedures, ensuring not only strength and aesthetics but also precise control over deformation to guarantee long-term, stable performance.
Excellence in Every Layer: The Four-Pass Welding Process
Take a single weld seam as an example—JX Filtration’s welding standards require four passes of filling welds to ensure a seamless, robust, full, and visually uniform result. After each pass, the weld must cool completely (typically taking 3-4 hours) before the next pass begins. Continuous welding is strictly prohibited!
Why such strict requirements? Because continuous welding can lead to:
✅ Increased risk of deformation: Sustained high temperatures from the welding arc cause prolonged thermal expansion in the weld zone and surrounding metal. Uneven cooling then generates internal stresses, leading to workpiece distortion.
✅ Degraded material performance: Prolonged high temperatures alter the microstructure of stainless steel, significantly reducing its corrosion resistance and mechanical properties.
✅ Unstable weld quality: Rapid multi-layer welding can introduce defects like porosity and slag inclusions, compromising strength.
Where Expertise Meets Craftsmanship
At JX Filtration, welding is not just a technical task—it’s an art. Our highly skilled welders, drawing on years of experience and intuition, meticulously control current, speed, and interpass temperatures to ensure every weld achieves optimal quality.
Patience in cooling is our commitment to excellence; strict adherence to process is our promise to customers. JX Filtration upholds the spirit of craftsmanship in every piece of equipment, delivering high-precision, high-durability, and high-reliability products through rigorous techniques and unwavering dedication.
