Soldering Brass tubes to brass assembly

Objective
To simultaneously solder two brass inlet/outlet tubes to a brass water jacket assembly with induction heating.

Equipment
UPT S2 Power Supply
HS-4 Heat Station

Key Parameters
Power: 1.3 kW
Temperature: 424°F (217°C)
Frequency: 220 kHz
Time: 30 seconds until the alloy flows; 40 seconds to allow alloy to even out around the tube.

TEST 1

Materials
• Brass water jacket assembly
• Lead-free solder alloy
• Utility paste soldering flux

TEST 2

Materials
• Brass water jacket assembly
• Lead-free solder alloy
• Utility paste soldering flux

Results:

Brass inlet/outlet tubes were successfully brazed to the brass assembly with induction heating. The piece needs to be positioned so that the tube is close to the end of the coil. The solder joint on the thin wall of the assembly will reach soldering temperature in 20 seconds. The second solder joint will reach soldering temperature an average of 10 seconds later (30 seconds total). An additional 10 seconds of heating might be necessary to allow the solder to flow evenly around the tubes to improve final quality and appearance.
