# Electrode Tips | \u00d8 16 mm | D Type | Pack size: 4 pcs<\/p>\n
**Part Number:** 497085<\/p>\n
This product is part of the professional welding technology range from Wiel\u00e4nder+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.<\/p>\n
## Product Description and Key Features<\/p>\n
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.<\/p>\n
**Key Features:**<\/p>\n
* **Design:** The D-type design is characterized by an **eccentric (off-centred)** tip, which allows welding even in narrow or hard-to-reach areas where conventional, centred electrodes encounter obstacles.
\n* **Material Quality:** The electrode tips are made of **Zirconium copper**. 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 prematurely.
\n* **Accuracy and Durability:** The use of zirconium copper guarantees consistent quality of the weld spots, minimizing maintenance requirements and extending the tool's service life.<\/p>\n

## Application Areas<\/p>\n
These electrode heads are ideal for resistance spot welding tasks in the following areas:<\/p>\n
1. **Automotive Body Repair:** Particularly suitable for the complex structures of modern vehicles, where reinforced elements and tight spaces require a special electrode shape.
\n2. **Sheet Metal Welding:** Any industrial or workshop application where precise, small-area welds are required.
\n3. **Repair Meeting OEM Specifications:** Wiel\u00e4nder+Schill products often comply with the strict quality and technical specifications of Original Equipment Manufacturers (OEMs).<\/p>\n
## Advantages of Zirconium Copper in Welding<\/p>\n
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:<\/p>\n
* **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 face for longer, even under intensive use.
\n* **Excellent Electrical Conductivity:** The copper-based material ensures outstanding current transfer, which is essential for delivering the optimal welding current to the workpieces.
\n* **Excellent Wear Resistance:** With D-type, eccentric tips, the mechanical and thermal stress on the tip is significant. The excellent hardness of the zirconium copper ensures that the tip geometry is maintained for a long time, thereby reducing the need for frequent grinding or replacement.<\/p>\n
## Maintenance and Use<\/p>\n
To ensure maximum performance and extend the life of the electrode, it is recommended to observe the following:<\/p>\n
1. **Regular Inspection:** Check the condition of the electrode tip between welding cycles. For D-type tips, preserving the geometry of the tip (the contact surface) is particularly important.
\n2. **Reshaping:** When tip wear or deformation begins to affect weld quality, the electrode tip must be reshaped to the correct geometry, ideally using a dedicated grinding tool.
\n3. **Correct Setup:** Ensure that the electrode tip fits tightly into its holder, and that the welding machine settings (current, pressure force, time) match the thickness and type of the material being welded.<\/p>\n
This set of 4 ensures you always have spare, factory-quality type D electrode heads available for the most demanding spot welding tasks.<\/p>","protected":false},"excerpt":{"rendered":"
