High Productivity Low Dilution Overlay Welding Systems for Chemical Industries

Product Description

 

Product Description

The Overlay Process

Through the weld overlay process, the base metal surface is covered with one or more additional metals. As a result, the base metal is protected from deterioration when exposed to a corrosive environment. Although different arc welding methods can be used to perform the overlay, it is important to consider the compatibility of the overlaying metal with that of the base metal. Important reasons for weld overlay include:

• Improving corrosion resistance and other beneficial properties of the base metal.
• Improving the service life of the component.
• 

  

  
  
   

The compact type vertical cladding station is designed for oil and gas, chemical, valve manufacturing, pressure vessels and other industries. Requirements of products with a variety of shapes can be met. This model can be used for precision welding of corrosion-resistant and wear-resistant materials.

With compact design, this model is space-saving and  powerful. Configured with the basic functions of internal and external surface together with flat surface welding, this mode also boasts optional functions such as two holes 90-degree crossing intersection surface cladding, multi-bore intersection surface automatic welding, workpiece pre-heat system, workpiece cooling system, etc. For final function blocks of your machine, please refer to commercial contract options.

Fitco offers fully automated TIG cladding welding systems for vertical valve-cladding applications. Complete turnkey packages include a wire-feed unit as well as a standard touch-programmable, hot-wire pulsed-TIG welding power source with an optional hot-wire system available for applications where higher deposition rates are required.
