Muffler Welding is a process involving several welding techniques that are essential to ensure the performance, durability and tightness of the exhaust system, especially the muffler. Factors such as material compatibility, heat affected zone control, sealing and welding location should also be considered during welding to ensure welding quality and efficiency. Recent technological advances have focused on increasing the automation of welding operations and the durability of materials, further optimizing the production and servicing of mufflers.
