This product description presents copper-plated steel washers that serve as accessories for Wieländer+Schill's professional body repair tools, specifically developed for the precise and efficient repair of damaged parts of vehicles, particularly applied to resistance spot welding technologies. These components are essential during dent repair processes, ensuring reliable adhesion and excellent weld quality.
The copper-plated washers belong to the category of consumables for Wieländer+Schill single-sided spot welding guns (Single Sided Spot Welding Gun GT). Their main purpose is the restoration of damage on body parts, such as dents, where the washer is welded onto the damaged surface and then, with the help of a pulling tool (e.g., a pulling stud or a slide hammer), the panel is returned to its original shape.
The copper plating plays a critical role in optimizing the welding process. Copper's excellent electrical conductivity ensures optimal current transfer between the welding electrode and the washer, minimizing resistance and heat loss in unwanted areas. This allows for the creation of more stable and reliable weld spots, which is essential for maintaining the structural integrity of the car body.
The table below details the precise dimensions and material characteristics of the copper-plated washers:
| Property | Value | Note |
|---|---|---|
| Part number | 497028 | The unique identifier of the product |
| Coating | Copper-plated | Excellent electrical conductivity |
| Material | Steel | High-strength base material |
| Diameter (Ø) | 8 mm | Basic dimension of the weld spot |
| Length × Width × Height | 16 x 16 x 1.45 mm | Dimensions of the entire washer |
| Packaging Unit (PU) | 100 pieces | Package contents |
| Weight (net) | 0.170 kg | Weight of the 100-piece package |
The copper plating ensures the low contact resistance necessary during the welding process. This is particularly important in resistance spot welding, where rapid and concentrated heat generation is key. The coating minimizes sparking and melting of the washer, resulting in a clean and strong bond with the metal surface to be repaired.
The washers are made of durable steel, which guarantees that during pulling operations (dent pulling), the washer will not tear off at the weld point, but rather the metal sheet itself will deform in the desired manner. The 1.45 mm thickness ensures an optimal balance between rigidity and weldability.
These consumables can be closely integrated into Wieländer+Schill's professional welding technology, especially with XSeries systems and the Single Sided Spot Welding Gun GT pistols. The product meets the high standards required for professional body repair, supporting precise and durable repairs.
The 100-piece package (PU: 100 pcs.) is an ideal choice for workshops, ensuring a continuous supply for daily repair tasks while optimizing procurement costs.
These copper-plated discs are ideal for any body repair operation where the damaged surface needs to be restored using an external pulling force, including:
Dent Repair: Removal of small and medium-sized dents from body panels.
Preparation of damaged sheets: Creating weld points for metal pulling without needing access to the back side of the surface being repaired.
Professional paint shops: Areas where surface quality and repair durability are paramount.
Wieländer+Schill is committed to the highest quality standards. Manufacturing processes are subject to strict quality control, supported by the company's ISO 9001 (Quality Management) and ISO 14001 (Environmental Management) certifications. This guarantee ensures that the discs with part number 497028 provide consistent performance during every use.
In summary: The copper-plated, 8 mm diameter steel discs (100 pcs./pack) are essential consumables for modern, efficient, and high-quality body repair, especially when using resistance spot welding technologies.
