Wieländer+Schill Aluminum Welding Studs (AlSi12 | M4 × 15 mm), 100 pcs | 367015
type: Product
description: Product Overview The Wieländer+Schill AlSi12 Welding Studs (Item No: 367015) represent a critical shift in collision repair consumables: transitioning from steel dent pulling to dedicated aluminum panel repair. Measuring 4.0 mm in diameter with an M4 metric machine thread and 15 mm in length, these specialized fasteners are engineered exclusively for use on automotive aluminum sheet metal, such as modern hoods, doors, liftgates, and structural components. Unlike the copper-plated steel studs used with standard resistance spot welders, these AlSi12 studs must be applied using a Capacitor Discharge (CD) aluminum stud welder. The AlSi12 (Aluminum-Silicon) alloy provides excellent metallurgical compatibility with automotive-grade aluminum, ensuring a strong, structural weld without burning through the thin, heat-sensitive panel. Key Features AlSi12 Aluminum Alloy Core: Manufactured from an Aluminum-Silicon alloy (AlSi12) that perfectly matches the metallurgical requirements of OEM automotive aluminum panels, ensuring deep fusion and maximum pulling strength. M4 Metric Machine Thread: Features a standard M4 thread pitch, which is the industry standard for aluminum pulling rings, collets, and metric dent extraction hardware. 15mm Optimized Length: Provides the perfect balance; long enough to attach standard M4 pulling eyes or threading nuts, but short enough to minimize lateral flex during delicate aluminum dent extraction. Ignition Tip Design: Features a small, precision-machined ignition pip (tip) at the base. This tip is required for the Capacitor Discharge (CD) welding process, vaporizing instantly to create the welding arc before plunging the stud into the molten pool. Bulk 100-Piece Packaging: Packaged in quantities of 100 pieces, acknowledging that technicians often need to weld dozens of aluminum studs in close proximity to distribute pulling force across a dented aluminum panel safely.
