The adjacent triangular sections and flat sections form a solder strip unit. And then annealing the pressed welding strip wire, and immersing the wire into a tin pool for tin plating after annealing.
Because the pressed welding strip wire rod can be tinned only by annealing, the two ends of the pressed welding strip wire rod are subjected to electric heating annealing in the annealing process, and a transition section is usually required to be arranged between the adjacent triangular sections and the flat sections in order to avoid the wire breakage caused by the sudden change of the cross sections at the joints of the adjacent triangular sections and the flat sections. Thus, in practice, each solder strip unit comprises three parts, a triangular section, a transition section and a flat section.
