Yes, it does matter what solder you use. The selection of solder is crucial to ensure the quality of the brazed joints and to prevent damage to the base materials. Here's a detailed explanation:
-
Melting Point: The solder must have a suitable melting point. If the melting point is too low, the strength of the brazed joint will be compromised. Conversely, if the melting point is too high, it can cause the grains of the matrix metals to grow, leading to deterioration in mechanical properties and potential over-burning or corrosion.
-
Wettability, Diffusivity, and Filling Gap Ability: The solder should have good wettability, meaning it should spread well over the base metal. It should also have good diffusivity, allowing it to mix well with the base metal, and it should be able to fill gaps effectively. These properties ensure a strong and reliable joint.
-
Linear Expansion Coefficient: The linear expansion coefficient of the solder should be close to that of the base metal. If there's a significant difference, it can lead to larger internal stresses and even cause cracks in the brazing seam. This is because the materials will expand and contract at different rates when subjected to temperature changes.
-
Technological Requirements: The brazed joints should meet the technological requirements of the products, such as adequate mechanical properties, corrosion resistance, conductivity, and thermal conductivity. This ensures that the joint performs well in its intended application.
-
Plasticity of the Filler Metal: The solder itself should have good plasticity, meaning it should be able to be shaped and formed into various forms like wire, strip, or foil. This allows for versatility in application and can help ensure a good fit with the base metal.
In summary, the choice of solder is a critical aspect of the soldering process. It affects the strength, reliability, and performance of the joint. Therefore, it's essential to select a solder that matches the specific requirements of the materials being joined and the application.
