Heat Exchanger Manufacturing
There are certainly some unique applications and challenges associated with the welding of heat exchangers, such as the position and access for the popular circumferential welding of Tube to sheet welds or the half tube shell welding.
With the varying alloys and applications, the selection of one process of welding is now available…. TIP TIG.
It is critical to have the best possible control of the weld process to address these challenging weldments. TIP TIG is a process that welds any alloy in “all positions”.
A trained TIP TIG welder can typically weld a 2” tube in 30 seconds… or less with the highest quality and lowest heat input. Our typical travel speed for fillet welds will be between 12-20” min on most applications. Compared with 3-6” min with conventional GTAW
With our manual system you can provide a low cost semi-automatic solution to tackle any job. We offer a wide variety of torches for different applications. Our modified 180 deg torch will allow a complete tube sheet welds without repositioning the wire or stopping, allowing for defect free welds.
The typical customers we serve in the manufacturing and repair of various sized heat exchangers are in power plants, chemical plants, petrochemical plants, petroleum refineries, natural gas processing, and sewage treatment.
