Welded Component Series

The welded components for three-way catalytic converters refer to a complete, ready-to-install exhaust system module in which the converter serves as the core element and is integrated with the inlet pipe, outlet pipe, flanges, sensor fittings, and other parts through welding processes. It is no longer a single emission-control component, but a composite assembly that incorporates environmental purification, mechanical connection, and sealing functions. The welded component series for three-way catalysts represents the trend toward modularization, integration, and plug-and-play design in catalyst products. By integrating the core catalytic function with the necessary mechanical structure, it provides users with a convenient maintenance solution. This series covers a wide range of products—from OEM premium models to cost-effective aftermarket versions, and from close-coupled front sections to under-floor main sections—making it an important and mature product category in the automotive aftermarket exhaust system sector. Choosing the correct welded component series is key to ensuring vehicle emissions compliance, performance restoration, and long-term stable operation.
