Total Energy Estimation Model for Remote Laser Welding Process

Planning of remote laser welding processes

The paper discusses the technical background of the remote laser welding (RLW) technology, its novel opportunities and implications for planning processes. Our ultimate goal is to develop a complete off-line programming toolbox for RLW which can provide an automated method for computing close-to-optimal robot programs. We suggest a workflow for the complete planning process, and propose new mod...

Process planning and offline programming for robotic remote laser welding systems

The paper introduces a complete offline programming toolbox for remote laser welding (RLW) which provides a semi-automated method for computing close-to-optimal robot programs. A workflow is proposed for the complete planning process, and new models and algorithms are presented for solving the optimization problems related to each step of the workflow: the sequencing of the welding tasks, path ...

Task Sequencing for Remote Laser Welding in the Automotive Industry

This paper proposes a new model and algorithm for task sequencing in remote laser welding in the automotive industry. It is shown that task sequencing (in which order to weld the seams) is strongly related to path planning (how the welding robot should move), therefore the two problems must be solved together, in an integrated way. The problem is modeled as a direct product of a traveling sales...

Collision-free Path Planning for Remote Laser Welding

The paper proposes algorithms for collision-free path planning in robotic Remote Laser Welding (RLW), using collision detection on a triangle mesh representation of the moving objects and a path planning algorithm based on a classical A∗ search, both highly specialized to the needs of RLW. The algorithms depart from an optimized task sequence and an initial, potentially colliding rough-cut path...
