Welcome to Wonder Weld Induction.

What is induction heating?

Faraday (1791-1867) was familiar with the fundamental principles underlying induction heating. As you can see, induction heating has been around for a long time.The effect of induction for a long time was undesirable at the time causing heat and making generators and transformers as well as motors less efficient. Interest in the possibility of melting metals by induction started in 1916. One of the earliest commercial applications was the melting of small charges using spark-gap oscillators. Another popular use was to heat metallic elements of vacuum tubes to drive off absorbed gasses prior to sealing. As World War II approached many independent companies started realizing the potential for induction. Once this era came in induction heating has progressed at the same speed as the desk top computer. In fact, today you can purchase a kitchen stove that uses induction heating to cook with. The key to cooking with induction is that the pots and pans are made from a material that heats efficiently and quickly. If you are interested in an application, please feel free to call. Thank you

Induction heating occurs when an ac voltage is rectified to dc voltage and is then pulsed thru a tank circuit to once again become an ac voltage. Using control boards and feedback systems we are able to raise and lower its potential. There are many factors that are to be considered when designing and using induction heating. One of the most important is the frequency at which to pulse the circuit. Many different types of steels, alloy steels, copper, stainless steel and other types of material require different parameters to effectively be used for induction heating applications.

Below is a small diagram example of induction heating.
