Precision resistance welding
WebWeldability for resistance welding in general and spot welding in particular can be expressed by the following relationship: Percentage Weldability . where, W = percentage weldability, ρ = electrical resistivity of work material, micro-ohm per cm (µΩ/cm), k = relative thermal conductivity with copper equal to 1.00, t m = melting point, °C. WebMar 21, 2024 · Exploring 6 Advanced Welding Technologies. 1. Laser welding. Laser radiation heats the surface to be machined, and the heat is guided into internal diffusion through heat transfer. By controlling the laser pulse width, energy, peak power, and repetition frequency, the workpiece is melted to form a specific molten pool.
