Solder joint of mid frequency welder [DCS09]
Dec 26,2023
Speaking of mid frequency welder we usually mention the solder joint.
The solder joint consists of the fusion zone, the heat-affected zone and the adjacent base metal. The solder joint produced by welding is the most basic element of welding structure, and in many cases, it is also the weakness of welding structure.
Prominent problems with solder joints include:
- Geometric discontinuities (sudden changes in shape and size possibly cause various welding defects) result in stress concentration, reduce the bearing capacity of solder joints, and produce fracture sources.
- Heterogeneity in mechanical properties. There are likely to be brittle zones, softening zones, and various poor quality zones at solder joints area.
- The existence of welding deformation and residual stress.
Solder joint coefficient
The solder joint coefficient is the ratio of the strength of the butt joint to the strength of the base metal. It is used to reflect that the strength of solder joint is weakened because of welding materials, welding defects and welding residual stress. It is a comprehensive reflection of mechanical properties of solder joint.
