What Is Tinning? And Why Is It Important? – Welding Mastermind

The process of tinning is when anything gets coated with a layer of melted tin. Tinning is crucial because it limits corrosion on metal devices, parts, and solder joints; cleans up the ends of wires; and makes your soldering tip last longer. Soldering and working with wires is a messy and challenging job.
