The type and design of the induction coil determines how effectively and efficiently a workpiece is heated. Work coils range in complexity from a simple helical- or solenoid-wound coil (consisting of a number of turns of copper tube wound around a mandrel) to a coil that is precision-machined from solid copper and brazed.

Induction heating uniformity issues can cause a variety of problems with part quality. We often see these issues because of irregular heating patterns due to unusual part shape or nontraditional heating requirements.

Here are six ways you can augment your induction coil design or heating process to address common heating uniformity problems.

In the latest induction heating application video from THE LAB at Ambrell, a steel mandrel is preheated for a hard facing application with an Ambrell EKOHEAT^® induction heating system and a custom-designed helical coil. As you can see in the video, heating the steel mandrel took just over one minute. 

Ambrell Corporation, an inTEST Company and a leading manufacturer of induction heating solutions, will exhibit at three different industry events during the month of May. The first event is the Offshore Technology Conference (OTC), which will be held at NRG Park in Houston, Texas, from May 6th to 9th. The next event is EASTEC 2019 at the Eastern States Exhibition in West Springfield, Massachusetts, from May 14th to 16th. To finish off the month, Ambrell will have an exhibit at CWIEME Berlin. This event will be at the Messe Berlin Exhibition Grounds in Berlin, Germany, from May 21st to 23rd.
