Welding is not only required after the welding is completed, but also includes whether the stress of the weldment is eliminated after the welding is completed, whether hydrogen is discharged at the weldment interface, and whether anti-corrosion treatment is performed.
So what can be done to improve the metallographic structure and properties of welded joints?
At present, the commonly used method is post-weld heat treatment, and the commonly used methods of post-weld heat treatment are induction heating and fuel heating.
Induction Heating Equipment is widely used due to its special working principle, high heating efficiency and low cost. Especially the fully Digital Induction Heating Equipment newly developed by POLARIS-ETeK adopts PLC control and IGBT inverter technology, which perfectly eliminates the The stress of the weldment and the elimination of hydrogen after welding improve the anti-corrosion ability of the weldment.
And our medium frequency induction heating equipment can be used together with other heating methods, such as resistance heating. The specific application should be combined with the specific working conditions of the site.
And According to the on-site situation of our cooperative customers, our intermediate frequency induction heating equipment general girth welds, straight welds, headers and other types of products can be easily used, but the specific situation is analyzed in detail, if you have relevant requirements , Welcome to Inquire, POLARIS-ETeK is committed to solving all kinds of induction heating problems for everyone in one-stop.
