'After it cools slightly, reheat it to brazing temperature once again'
Explicación
## Step 1The problem is about the correct procedure to follow after brazing a copper-to-copper joint. Brazing is a method used to join metals by melting and flowing a filler metal into the joint, which then cools to form a strong bond.## Step 2The options provided are:- Apply additional flux as the joint cools- After it cools slightly, reheat it to brazing temperature once again- Wipe the joint down with a wet rag after the filler metal has hardened## Step 3The correct procedure after brazing a copper-to-copper joint is to allow the joint to cool down. This is because the filler metal needs to harden and form a strong bond between the copper pieces.## Step 4Applying additional flux or reheating the joint to brazing temperature once again is not necessary and could potentially damage the joint.## Step 5Wiping the joint down with a wet rag after the filler metal has hardened is also not necessary and could potentially remove the filler metal, weakening the joint.
