Heat Exchanger Welding

Heat exchangers are commonly constructed from low Carbon Steel, Copper, Copper-Nickel, Stainless Steel, Hastelloy, Inconel, or Titanium.

There are certainly some unique applications and challenges associated with welding heat exchangers, such as the position and access for the popular circumferential welding of Tube to sheet welds or the half-tube shell welding.

It is critical to have the best possible control of the welding 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 TIG.

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 complete tube sheet welds without repositioning the wire or stopping, allowing defect-free welds.

The typical customers we serve in the manufacturing and repair of various-sized heat exchangers are power plants, chemical plants, petrochemical plants, petroleum refineries, natural gas processing, and sewage treatment.
