Induction Post Weld Heat Treatment (PWHT)
Post-weld heat treatment (pwht machine) is a stress release process by heating the welded zone after the workpiece is welded, which is an indispensable step to ensure the welding quality. Usually, this kind of post weld heat treatment procedure/processs is done with the induction heating machine. Take JKZ's induction heating devices as examples. These devices will normally first heat the workpiece at the temperature of 100-150 degrees/hour and they will gradually reach the target temperature at 650-780 degrees according to different metal material features. All the processes will be completed perfectly in accordacne with the pre-set heating time ...

Common Quality Problems of Induction Quenching Machine and Ways to Improve Its Working Performance
Table of Content [Hide] Ⅰ. Quality problems that often occur in high frequency hardening Ⅱ. Ways to improve the working performance of super audio frequency or high frequency induction heating power supply Ⅰ. Quality problems that often occur in high frequency hardening The application of high frequency induction guide pin quenching machine in the quenching process is becoming more and more extensive. With the continuous improvement of this process, we generally encounter the following problems: The workpiece is cracked: the heating temperature is too high and the temperature is uneven. Improper selection of quenching medium and temperature. Untimely and insufficient tempering. The hardenability ...
The Temperature Control Method of Induction Heating Machine
As the popularity of induction heating machines gradually rises in different industry areas, the temperature requirements for different workpieces has also gotten higher and higher. To better induction heating control the temperature during the heating process, you can use the following two methods: induction heating temperature control: According to the temperature rise curve of the heating process, use infrared temperature measurement or thermocouple for temperature sampling and convey the corresponding feedback to the industrial induction heating machine. Then, control the heating process by adjusting the working time and power of the equipment through the single-chip microcomputer. Typical applications of this ...
