  1. Process Overview Flexible stainless steel corrugated tubes are widely used in HVAC, industrial gas systems, plumbing and mechanical equipment connections. Thanks to their thin-wall and flexible corrugated structure, they absorb vibration and fit complex installation layouts. However, traditional fusion welding and TIG welding easily cause common defects including tube burn-through, corrugation collapse, loss of flexibility and joint leakage, due to excessive heat input. Our professional brass brazing process solves these problems perfectly. Using dedicated brass welding wire for flexible stainless steel, we adopt low-temperature capillary brazing instead of high-temperature fusion welding. The process does not melt the stainless steel base material, preserves the original flexibility of the tube, and delivers strong, leak-proof joints with excellent consistency and cost efficiency.   2. Core Advantages Our optimized brazing process is specially developed for thin-wall flexible stainless tubes, with four key technical and commercial benefits: • No Deformation, Full Flexibility Retention Brazing is performed at a low temperature, far below the melting point of stainless steel. Heat is strictly limited to the sleeve joint area without heating the corrugated flexible section. This completely avoids softening, collapsing or structural damage, ensuring the tubes retain full bending and vibration compensation performance after welding. • Superior Sealing Performance We control precise assembly clearance to enable full capillary penetration of the brazing material. The filler metal uniformly fills the entire joint gap to form a dense, void-free brazed fillet. No porosity, no cold joints, and zero leakage risk for long-term operation. • Excellent Cost Advantage Under High Copper Price Conditions With continuous high copper and silver material prices worldwide, traditional silver brazing greatly increases production costs and compresses profit margins. Our dedicated brass welding wire provides stable and reliable joint quality equivalent to standard silver brazing in normal working conditions, while reducing welding material costs by 30%–60%. It is the most cost-effective mass production solution for the current high raw material price environment. • High Stability & High Yield Rate We implement a standardized full-process workflow including surface polishing, precise flux application, controlled heating and professional post-wash treatment. The optimized low-heat welding method eliminates burn-through and deformation issues. The finished product yield rate stably reaches over 99%.   3.

  As global industries move toward greener manufacturing, carbon emissions have become an important factor in supplier selection. From HVAC systems and refrigeration equipment to automotive components and industrial fabrication, manufacturers are increasingly looking for welding and brazing materials that not only deliver reliable performance but also contribute to sustainability goals. At XINXIN Welding Materials, we believe that strong joints and environmental responsibility can go hand in hand.   Why Carbon Footprint Matters in Brazing Materials Every product has a carbon footprint—the total greenhouse gas emissions generated during raw material extraction, production, packaging, and transportation. For brazing and welding materials, carbon emissions mainly come from: Metal refining and processing • Manufacturing operations • Energy consumption during production • Packaging materials • International transportation Reducing emissions throughout these stages helps manufacturers build more sustainable supply chains and meet growing environmental requirements.   Efficient Production, Reduced Environmental Impact At XINXIN Welding Materials, we continuously improve production efficiency to reduce unnecessary energy consumption and material waste. Through optimized manufacturing processes, strict quality control, and efficient resource utilization, we strive to: • Reduce raw material waste • Improve production efficiency • Lower energy consumption per unit produced • Extend product service life through consistent quality A high-quality brazing rod not only creates stronger joints but also reduces rework, rejects, and material waste during manufacturing.   Longer Service Life Means Lower Lifecycle Emissions The environmental impact of a brazed joint is not limited to production. Reliable brazing materials help equipment operate longer and require fewer repairs. This reduces replacement frequency, maintenance costs, and the associated carbon emissions over the product's entire lifecycle. Our products—including: • Brass Brazing Rods (RBCuZn-A, RBCuZn-C) • Copper Phosphorus Brazing Alloys (BCuP Series) • Silver Brazing Alloys • Aluminum Brazing Fluxes • Copper Brazing Fluxes Are designed to provide stable performance and durable connections across HVAC, refrigeration, automotive, and industrial applications.   Supporting Sustainable HVAC and Refrigeration Industries Modern HVAC and refrigeration systems play an important role in global energy efficiency.

  “We Thought the Problem Was the Aluminum Rod…” Last year, one of our customers in Southeast Asia contacted XINXIN WELDING about a problem in aluminum brazing. They were producing aluminum heat exchangers for air conditioning systems. At first, the factory believed the issue came from the aluminum brazing rod itself. The workers complained that: ▶ the filler metal was difficult to flow, ▶ some joints looked dry, ▶ and after pressure testing, small leakage problems appeared repeatedly. To solve the problem, they tried: ▶ changing the flame temperature, ▶ replacing different aluminum rods, ▶ increasing heating time. But nothing really improved. In fact, overheating made the aluminum parts deform even more.   After discussing the production process with their engineers, we discovered one important detail: they were using a very low-quality aluminum brazing flux with unstable performance. The flux could not effectively remove the oxide layer from the aluminum surface. This is actually a very common problem in aluminum brazing. Unlike copper, aluminum oxidizes extremely fast once exposed to air. Even if the surface looks clean, a thin oxide layer already exists. Without a stable brazing flux, the filler metal simply cannot wet the base material properly.   We suggested they test XINXIN WELDING QJ201 Aluminum Brazing Flux. The customer first used it on a small batch production line. The feedback came back surprisingly fast. Their workshop supervisor said: “The first thing we noticed was the filler metal started flowing much faster. The brazing area looked cleaner, and workers no longer needed to repeatedly heat the same joint.” A week later, the factory reported another improvement: the leakage rate during pressure testing dropped significantly. For them, this was more important than anything else. Because in HVAC manufacturing, every leakage problem means: ▶ rework, ▶ wasted material, ▶ delayed delivery, ▶ and unhappy customers. After two months, the customer fully switched to QJ201 Aluminum Brazing Flux from XINXIN WELDING.   Today, they mainly use it for: ▶ aluminum heat exchangers, ▶ aluminum tube connections, ▶ automotive radiator parts, ▶ and refrigeration system components. Many people think brazing flux is only a “supporting material.” But experienced factories know: sometimes the success of the entire brazing process depends on the flux itself.   At XINXIN WELDING, we focus on helping customers achieve more stable production, cleaner brazing results, and lower defect rates — not just selling materials.
