Part number: 497085
This product is part of the professional welding technology range from Wieländer+Schill, specifically developed for resistance spot welding applications. The high-quality D-type electrode heads ensure precise and reliable welding results in body repair and metal processing.
The product with article number 497085 is available in a four-piece package (PU: 4 pcs), consisting of 16 mm diameter, D-type electrode heads. These electrode heads are crucial for creating effective and durable spot welds, especially in cases where standard electrode designs cannot reach the surface to be welded.
Key Features:
Configuration: A characteristic feature of the D-type design is the eccentric (off-centred) tip, which makes welding possible even in narrow or hard-to-reach areas where the use of traditional, centrally-focused electrodes encounters obstacles.
Material quality: The electrode heads are made of zirconium copper (Zirconium copper) material. This alloy provides excellent electrical conductivity and high heat resistance, which is essential for fast and repeatable welding cycles without the electrode deforming or wearing out prematurely.
Accuracy and Durability: The use of zirconium copper material guarantees consistent quality of the weld spots, minimizing maintenance requirements and increasing tool lifespan.

These electrode heads are ideal for resistance spot welding tasks in the following areas:
Vehicle Body Repair: Especially suitable for the complex structures of modern vehicles, where reinforced elements and confined spaces require special electrode shapes.
Sheet Metal Welding: Any industrial or workshop application where precise, small-sized weld spots are required.
Repairs Compliant with OEM Specifications: Wieländer+Schill products often comply with the strict quality and technical specifications of Original Equipment Manufacturers (OEMs).
The material of the welding electrode is a critical factor in the success of the welding process. The use of zirconium-copper (CuZr) alloy offers several advantages over traditional copper alloys:
Higher Softening Temperature: The addition of zirconium significantly increases the material's resistance to softening at high temperatures. This means the electrode can maintain its sharp, precise welding surface for longer, even under intensive use.
Excellent Electrical Conductivity: The copper-based material ensures excellent current transfer, which is essential for delivering the optimal welding current to the workpieces.
Excellent Wear Resistance: With type D electrodes featuring an eccentric design, the mechanical and thermal load on the tip is significant. The hardness of the zirconium-copper alloy ensures that the tip geometry is maintained for a long time, thus reducing the need for frequent grinding or replacement.
To ensure maximum performance and extend the life of the electrode, it is recommended to observe the following:
Regular Check: Check the condition of the electrode tip between welding cycles. For type D heads, preserving the tip geometry (the contact surface) is particularly important.
Reshaping: When tip wear or deformation begins to affect welding quality, the electrode head must be reshaped to the correct geometry, ideally using a grinding tool designed for this purpose.
Correct Fitting: Ensure that the electrode head fits tightly into its holder, and that the welding machine settings (current, force, time) match the thickness and type of the material to be welded.
This set of 4 ensures you always have spare, factory-quality type D electrode heads available for the most demanding spot welding tasks.
