Crosswire welding is an essential technique used to join two intersecting wires, often at a 90-degree angle. Known for its precision and strength, this method finds application in industries like battery manufacturing, electronics, automotive wiring, and wire mesh production. In this blog, we’ll explore the step-by-step process, recommend the right equipment from C-Welding, and weigh the pros and cons of cross-wire welding to help you make informed decisions for your projects.

What Is Crosswire Welding?

Cross-wire welding involves joining two wires by applying heat and pressure at their intersection. This is typically done using resistance welding, which generates heat through electrical resistance, melting the material locally. When combined with force, the wires fuse together into a solid joint.

This technique is ideal for creating conductive joints, structural reinforcements, or connections where minimal additional material is preferred. The result is a reliable, precise bond suitable for high-performance applications.

How to Perform Cross-Wire Welding

Step-by-Step Process

1. Positioning:
   • Align the wires at the desired angle, typically perpendicular.
   • Ensure they are securely clamped or held in place to avoid shifting during welding.
2. Machine Setup:
   • Use a resistance welding machine to configure the required parameters:
     • Current: Adjust the electrical current based on the wire material and thickness.
     • Force: Set the clamping force to ensure proper contact.
     • Weld Time: Optimize the duration of heat application for precise fusion.
3. Welding:
   • Activate the machine to apply current and pressure simultaneously.
   • Allow the heat to generate at the contact point, melting the wires and forming a joint.
4. Cooling:
   • Release the pressure only after the joint has solidified. Proper cooling is essential to prevent defects.
5. Inspection:
   • Check the weld for strength, uniformity, and conductivity to ensure it meets quality standards.
