Understanding Induction

An Alternative Heating Process

Al Sherrill (Miller Electric Mfg LLC) – Induction Technical Manager

11:30am – 12:00pm (CST)

Comparison of Preheat Methods:

Induction, Resistance, and Flame

Dave Hebble (ARC Specialties) – Technical Services Manager

Recently we completed a study comparing the Miller ARC Reach Heater and the Proheat 35 induction units to resistance and flame heating.  Testing was done on 8”, 12” and 16” pipe, ½” and 1 ½” plate, and a 550# I beam.  We will do a quick review of the results to see how they compare.

12:00pm – 1:00pm (CST)

Good vs Bad Coil Design

Dave Hebble (ARC Specialties) – Technical Services Manager

With lots of power available from the Proheat 35, we add turns to get better coupling and more power into the part. But, with the reduced output from the ARC Reach heater, we need to maximize efficiency in our coil design. We’ll look at some of the variables like the number of turns, spacing between the coils, direction of the wrap, and the space between the coil and the part to see how it changes the power going into the part.

1:30pm – 2:00pm (CST)

Interpreting Machine Process Parameters:

Human to Machine Interface

Jim Walker (ARC Specialties) – Weld Technicians

The Induction machines have a readout showing the amperage, voltage, power output, frequency, and source current to show how well the coil is coupled to the part. When any one of the variables reaches its maximum output, that’s all the power we can get out of the machine. We’ll look at what the numbers mean and what can be changed in the coil design to improve machine output.

2:00pm – 3:00pm (CST)
