Edge Preparation and Drilling for Heavy Welding Applications

Tecoi North America has introduced the TRF plate-processing machine, a solution for heavy welding edge preparation and drilling. The machine is designed for applications where large machining/milling capacities are required for medium and large thicknesses. It proves optimal for industries with demanding regulations that require critical welding edge preparation, such as wind-tower fabrication, civil construction, shipbuilding, large steel structures, large vessels and petrochemical infrastructure, according to company officials.

The TRF incorporates the company’s Cold Bevel Milling (CBM) technology to create complex bevels in a single, high-speed cut. CBM reportedly results in improved quality and dimensional tolerance, without affecting the material properties of the material. The edges need not be cleaned after the bevel is cut, and quality issues common with thermal beveling are eliminated. Bevels for narrow-gap welding can be milled in one pass. Customized milling tools with specific geometries are available.

The TRF also features an automatic multi-head system that duplicates productivity in the same processing station. A built-in automatic tool-storage/selection system also is available, capable of storing and configuring five tools for each job. A marking system can be provided for laser, plasma, scribing, micro-percussion and ink, with options available for text, numbers, bar codes, auxiliary lines, etc. Also optional: Tecoi's Vibratec chip-evacuation system, which reportedly can provide time savings to 40 percent in cleaning operations, waste removal and machine downtime.
