Flanged Weld Stud

Maintaining strict perpendicularity between the cylindrical shaft and the flange base is critical for these weld studs, ensuring reliable alignment during resistance welding operations. The component features a broad circular flange designed to maximize contact area with sheet metal substrates, while the stepped shaft provides a precise interface for subsequent mechanical assembly or positioning tasks.

Manufacturing focuses on controlling the flatness of the welding face and the concentricity of the shaft to prevent tilt or uneven current distribution during the joining process. High-precision automatic turning processes are employed to achieve consistent outer diameters and surface finishes, minimizing post-weld adjustments. Material selection typically involves carbon steel or stainless steel grades compatible with standard projection welding equipment, with heat treatment options available to enhance shear strength if required by the application.

Quality verification utilizes optical measurement systems to check critical geometric tolerances, including flange runout and shaft straightness, alongside hardness testing to validate material integrity. This approach supports high-volume production consistency for automotive chassis, appliance housings, and industrial equipment frames where structural stability under vibration is essential. Quotation parameters depend on shaft dimensions, flange diameter, material specification, and any specific plating requirements such as zinc or nickel.
