induction brazing steel carbide cap to shaft

Objective High Frequency Induction brazing steel carbide cap to shaft.  Customer currently uses a torch process, but would like to change to induction brazing in order to reduce scrap and rework and improve the quality of the braze.

Equipment DW-UHF-6kw-III handheld induction brazing heater Materials • Carbon steel • magnetic carbide caps • Alloy – EZ Flo 3 paste • Test 1: Shaft Diameter: 0.5” (12.7 mm) • Test 2: Shaft Diameter: 0.375” (9.525mm) • Test 3: Shaft Diameter: 0.312” (7.925mm)

Key Parameters Test 1: Shaft Diameter: 0.5” (12.7mm) Temperature: Approximately 1450°F (788°C) Power: Pre-curie – 3.3 kW Time: 11 seconds

Key Parameters Test 2: Shaft Diameter: 0.375” (9.525mm) Temperature: Approximately 1450°F (788°C) Power: Pre-curie – 1.8 kW Time: 8 seconds

Key Parameters Test 3: Shaft Diameter: 0.312” (7.925mm) Temperature: Approximately 1450°F (788°C) Power: Pre-curie – 1.7 kW Time: 7.5 seconds

Process:

1. Paste alloy was applied to the cone shape top of each steel shaft.
2. The cap was set on top and rotated to distribute the paste alloy.
3. Each assembly was positioned in the coil and heated.
4. Preliminary heat tests were conducted using tempilaq paint to estimate the heat cycle to 1450 degrees F.

Results/Benefits:

• Precise control of the time and temperature resulting in improved quality and consistent result
• Power on demand with rapid heat cycles
• Repeatable process, not operator dependent
• Safe induction heating with no open flames
• Energy efficient heating

Brazing Carbide to Steel Part With Induction Heating

Objective Brazing carbide to steel part Equipment DW-UHF-6kw Induction Heating Power Supply ultra high frequency custom coil Key Parameters Power: 1.88 kW Temperature: Approximately 1500°F (815°C) Time: 14 sec Materials Coil-  2 helical turns (20 mm ID) 1 planar turn (40 mm OD, 13 mm Height) Carbide-  13 mm OD, 3 mm wall thickness Steel piece– 20 mm OD, 13 mm ID

Induction Brazing Process:

1. To demonstrate elimination of “hand feeding” the alloy, we formed the alloy into a ring to tightly fit over the center post tube. This method provides a uniform amount for each cycle, resulting in uniform joints and wetting.
2. The custom made coil was then placed over the steel piece, where is was set for 14 seconds to heat the alloy.
3. The alloy was heated at approximately 1500°F (815)°C
4.  The whole piece is left alone and cooled with ambient air

Results/Benefits:

• Brazing was successful all in under 20 seconds with 2-kW
• High quality and repeatability of the brazed joints
• Increased productivity
• Rings will need to be developed for specific joints to prevent the use of too much alloy
• Precise control of the time and temperature
