PSI and our ASME Department are excited to announce the new vessel head profiler we acquired this summer! Manufactured by Müller Opladen in Germany and distributed in the United States by Watts Specialists, the RB 2000/6 is a state-of-the-art piece of equipment.
This head profiler is capable of cutting domes from 8” up to 100” in diameter. It features 6 CNC axis, self-centering three-jaw chuck with electric motor clamping process, torch head with 20°-160° oscillation, and is capable of a 380° torch rotation with a slide system for automatic advance and retraction in any angle position. It also has a laser sensor for correction of variation between the cutting torch and shell surface, and cutting trolley with 118” column carriage track.
The 3D profile-cutting machine makes use of both thermal cutting processes with oxy-fuel and plasma. The unit also features a Hypertherm HPR 400 plasma cutting system and an oxy-fuel cutting system. If plasma power source is selected, the cutting of wall thicknesses of up to 2” is possible. With oxy-acetylene we can cut up to a maximum wall thickness of almost 6” depending on tilt angle.
All of this is driven by a COROBS software package. Data imported from a CAD system is followed by the automatic definition of the cutting curves and the associated creation of a cutting file. COROBS-ROBO then sets the start and end points for the cutting task. After this, the overall cutting process of a cutting file is simulated with the depiction of the machine, the robot torch head and the work piece before the start of cutting.
As with the Watts Specialists’ pipe and shell profilers we currently have, this new head profiler has greatly improved production. What used to take 5 hours to lay out and hand torch a 72” control head for a heater treater, now takes about 45 mins. This equates to shorter lead-times as well as a reduction in price due to reduced labor.
Plus, in January 2016, we look forward to the addition of a Kawasaki welding robot! We will be featuring this new system in a future issue of the PSI Punchline.
