Steelwork ERECTION USING CIMSTEEL INTEGRATION STANDARDS
2015Co-Authors: R. Lipman, Vineet R. Kamat, Robert R. LipmanAbstract:Automation is being increasingly explored as a possible solution for safely increasing productivity in Structural Steelwork erection. A piece of automation equipment such as a robotic crane has no intrinsic knowledge of the steel erection process it automates. Thus, geometric and spatial information about a steel member and the motion sequences that must be executed to move that component from a staging area to its installed final location must both be programmed into the equipment. The equipment must minimally know where a steel member in question is currently staged, and what the final installed position and orientation of the member is in the erected structure. The presented research investigates the extent to which the CIMsteel Integration Standards (CIS/2) can specify product descriptions capable of supporting automated erection of Structural Steelwork. Algorithms to interpret steel member geometry and spatial configuration from CIS/2 files were designed. Then, a kinematically smart crane capable of accepting robot-like instructions was implemented in 3D virtual reality. The crane was programmed to utilize the algorithms to automatically extract member information from CIS/2, and to use that information to compile assembl

Evaluation of standard product models for supporting automated erection of Structural Steelwork
Automation in Construction, 2007Co-Authors: Vineet R. Kamat, Robert R. LipmanAbstract:Automation is being increasingly explored as a possible solution for safely increasing productivity in Structural Steelwork erection. A piece of automation equipment has no intrinsic knowledge of the steel erection process. Thus, geometric and spatial member information, and the motion sequences that must be executed to install steel members must both be programmed into the equipment. This research investigates the extent to which the CIMsteel Integration Standards (CIS/2) can support automated Steelwork erection. Algorithms to interpret steel member geometry and spatial configuration from CIS/2 files were designed. Then, using inverse kinematics principles from robotics literature, a kinematically smart crane capable of accepting robot-like instructions was implemented in 3D virtual reality. The crane was programmed to utilize the algorithms to automatically extract member information from CIS/2, and to use that information to compile assembly instructions for erecting the structure in the virtual world. Based on the obtained results, it was found that CIS/2 does encapsulate the basic geometry and position and orientation of steel members in a format that, after geo-referencing, can be used to support automated Steelwork erection. However, several processing steps are necessary to compute the information needed from the CIS/2 model for the process description of erection needed by the automation equipment.

STANDARD PRODUCT MODELS FOR SUPPORTING AUTOMATED ERECTION OF Structural Steelwork
Proceedings of the 23rd International Symposium on Automation and Robotics in Construction, 2006Co-Authors: Vineet R. Kamat, Robert R. LipmanAbstract:A piece of automation equipment such as a robotic crane for steel erection has no intrinsic knowledge of the process it automates. Thus, geometric and spatial information about a component such as a steel member, and the motion sequences that must be executed to move that component from a staging area to its installed final location must both be programmed into the equipment. In automated steel construction, the position and orientation of steel members in a temporary staging area is project and site dependent, and thus cannot be automatically determined beforehand. The final in-place spatial configuration (position and orientation) of a steel member, however, can be conceptually extracted automatically from a product model of the structure being erected. The presented research evaluates this hypothesis and investigates the extent to which the CIMsteel Integration Standards (CIS/2) can specify product descriptions capable of supporting automated erection of Structural Steelwork.

EMULATION OF AUTOMATED Structural Steelwork ERECTION USING CIMSTEEL INTEGRATION STANDARDS

However, several processing steps are necessary before the extracted data can be readily used to program automation equipment.

Modern hybrid welding process for Structural Steelwork engineering—Laser submerged arc hybrid welding
Journal of Laser Applications, 2016Co-Authors: Uwe Reisgen, Simon Olschok, Stefan Jakobs, Oliver EngelsAbstract:The welding of thick metal sheets has become increasingly important for Structural Steelwork engineering applications (e.g., pipe- or crane building). Nowadays, welding tasks are performed using a time-consuming conventional submerged arc welding process. Here, a large number of welding passes are necessary, which leads to a thermally induced distortion. Therefore, there is a high demand for a welding process which allows a cost-effective welding of thick metal sheets. By the development of a laser beam submerged-arc hybrid welding process (LUPuS), a technique is created which combines the high penetration depth of the laser with the high thermal efficiency of the submerged arc process. This leads to synergy effects which predestine LUPuS for the given welding task. Earlier projects have shown a general feasibility of LUPuS. Steel plates with thicknesses of up to 50 mm have been joined without any welding issues using the double-sided single pass technique. However, different results of the notch impact t...

Modern hybrid welding process for Structural Steelwork engineering-laser submerged arc hybrid welding
International Congress on Applications of Lasers & Electro-Optics, 2015Co-Authors: Uwe Reisgen, Simon Olschok, Stefan Jakobs, Oliver EngelsAbstract:The welding of steel with large plate thicknesses gains more and more in importance for the Structural Steelwork engineering (e.g. pipe- or crane building). Nowadays those welding tasks are performed by a time-consuming conventionally submerged-arc welding process. A large number of welding passes are necessary which are accompanied by thermally induced distortion. So there is a high demand for a welding process which allows the economical welding of thick steel plates with high plate thicknesses. By the development of a laser beam submerged-arc hybrid welding process (LB-SAW) a technique is created which combines the high penetration depth of the laser with the high thermal efficiency of the submerged-arc process. This leads to synergy effects which predestine LB-SAW for the given welding task. Further projects have shown the general feasibility of LB-SAW. Steel plates with thicknesses up to 36 mm have been joined without any welding errors with the double-sided single pass technique. As conspicuous prove the differing results of the notch impact test in the laser beam-dominated and the submerged-arc-dominated welding areas.This paper presents the latest welding results which are performed by LB-SAW. It was possible to increase the weldable plate thickness up to 50 mm by a simultaneous gain of process stability. Also the influence of different process distances in relation to synergy effects is shown.The welding of steel with large plate thicknesses gains more and more in importance for the Structural Steelwork engineering (e.g. pipe- or crane building).
