According to technical engineers from several Stainless Steel Float Ball Factory(https://www.yaokangvalve.com/product/stainless-steel-threaded-float-ball/) teams, the welding process plays a decisive role in maintaining airtight and watertight integrity. Because the float ball must remain hollow to provide buoyancy, even a microscopic defect in the weld seam can compromise its function. Thus, understanding how different welding techniques affect sealing quality is essential to ensuring consistent performance under various industrial conditions, including high pressure, temperature fluctuations, and corrosive environments.
