Final Answer:
The process described, with low distortion and high joint strength at 600 degrees Celsius, is most likely Brazing. Option B is the answer.
Step-by-step explanation:
Brazing is a metal-joining process that typically occurs at temperatures above 450 degrees Celsius. In brazing, a filler metal is melted and distributed between two or more close-fitting parts by capillary action. The process is known for its ability to produce joints with low distortion, as the base metals do not melt but are joined by the molten filler metal. This results in strong and durable joints.
Welding involves melting the base metals at the joint, and soldering occurs at lower temperatures than brazing. The specific characteristics mentioned—low distortion and high joint strength at 600 degrees Celsius—align closely with the attributes of brazing.
Option B is the answer.
