1. Surface Preparation The success of soldering hinges on proper surface preparation. Before soldering, it is essential to remove any oils, dirt, or oxidation from the surface. For galvanized iron, this often means using a wire brush or sandpaper to clean the area. It's also critical to remove the zinc coating at the joints to promote better adhesion.

The construction making machine consists of several components, including a wire feeding system, heating elements, cooling mechanisms, and control systems. The wire feeding system is responsible for supplying raw iron wire into the machine, where it is passed through a series of heating elements that raise its temperature to the required level for annealing. The cooling mechanisms then cool the wire down slowly to prevent it from becoming too brittle or hard.
