Welding Nails (reverse) Caldo GZONi 80 — Gwoździe do zgrzewania GZONi 80

Caldo GZONi 80 welding nails (reverse) are engineered fastening elements intended for spot and projection welding of sheet metal and similar substrates. The reverse configuration of these welding nails provides a robust contact point for resistance welding operations, enabling secure welded joints without through-bolting or additional mechanical fasteners. They are produced to meet typical workshop and industrial requirements where welded studs or nails provide a fixed anchoring point for subsequent assembly or components.

Advantages

The reverse design of the Caldo GZONi 80 reduces the likelihood of part deformation during welding and improves contact stability, producing consistent welds when used with compatible spot-welding equipment. Their geometry facilitates repeatable placement and efficient energy transfer during projection welding, resulting in reliable electrical contact and strong weld nuggets. The product is suitable for high-volume processes and repair work where time-efficient, permanent fastenings are needed.

Suitable for (tasks / use cases)

• Automotive sheet metal repair and bodywork attachment
• Metal fabrication and panel assembly in industrial production
• Spot welding where fixed anchoring points are required
• Repair shops and maintenance applications requiring welded fasteners

Key specifications

• Type: reverse configuration welding nails for projection/resistance welding
• Primary application: spot welding to sheet metal and thin substrates
• Material characteristics: metallic welding stud suitable for electrical resistance welding processes
• Compatibility: designed for use with standard spot/projection welding equipment and fixtures
• Function: provides a welded anchoring point without through-fastening

How to use

Select appropriate welding parameters for sheet thickness and material type, and position the Caldo GZONi 80 welding nail at the predefined attachment point. Use a projection or resistance spot-welder with suitable electrode geometry and force to ensure firm contact between the nail and the workpiece. Initiate the welding cycle and verify the weld nugget quality visually and, if necessary, by mechanical test to confirm adequate fusion. After welding, trim or finish the area according to assembly requirements.

Usage recommendations

Ensure welding equipment is calibrated for the substrate and nail material to avoid overheating or insufficient fusion. Use proper personal protective equipment and follow local safety procedures for resistance welding. For consistent results, test weld parameters on sample panels before series production and maintain clean contact surfaces free of coatings or contaminants that could impair electrical contact.
