John Prevish from United Precision Services will be presenting at Fabtech 2023! Please come see him and Jakub Dauco as they discuss Microstep dome cutting machines. United Precision Services is also exhibiting at Fabtech and can be visited at Booth A4987.
Cutting Hole Penetrations into Vessel Heads Creates Challenges in 3-D
Production of pressure vessels and boilers are major industrial applications where cutting 3D objects is an essential part of the process. Dome cutting involves creating openings in the dish ends of the vessel to allow for welding of inlet pipes or trimming of the edges for weld preparation to the vessel. Today, this mostly manual process of measuring the dish ends for hole locations and then hand plasma cutting is not only time consuming and costly, but also results in less desirable accuracy and weld preparation edge quality. Welding to the vessel body using V, X, or K-cuts with constant or variable bevels need to be produced with prescribed accuracy to meet welding requirements. Automation of this entire process can now be realized on a gantry style cutting machine utilizing new technologies that can scan (cloud-map) the dish ends and auto-calibrate the plasma torch to produce consistent and accurate results.
