What is brazing process and CTP/CTQ

Question

Accepted Answer

Brazing process involves joining metals using a filler metal that melts above 450°C. CTP/CTQ stands for Critical to Process/Critical to Quality.

Brazing is a metal-joining process where a filler metal is melted and distributed between two or more close-fitting parts by capillary action.
The filler metal has a melting point above 450°C but below the melting point of the base metals being joined.
CTP/CTQ are key parameters that directly impact the process or quality of a product.
CTP (Critical to Process) refers to parameters that are crucial for the successful completion of a process.
CTQ (Critical to Quality) refers to parameters that are crucial for ensuring the quality of the final product.
For example, in a manufacturing process, the temperature and pressure levels may be CTPs, while product dimensions and material properties may be CTQs.
