Types of copper soldering materials Copper soldering materials can be divided into two categories: soft soldering and hard soldering. Soft soldering is mainly used for low-temperature (below 500°C) and low-strength soldering, including silver soldering and brazing materials. Hard soldering is used for high-temperature (above 500°C) and high-strength soldering, mainly including copper solder wire and copper…
The reasons for the porosity in the welding with pressure openings are as follows During the construction of engineering welding with pressure openings, the bubbles in the weld pool of the pipeline failed to escape during solidification, and the holes formed in the weld metal of the pipeline (or the surface) are called pores. It…
