Welding Robot Collision-Free Path Optimization
Reasonable welding path has a significant impact on welding efficiency, and a collision-free path should be considered first in the process of welding robot path planning. The shortest path length is considered as an optimization objective, and obstacle avoidance is considered as the constraint condition in this paper. First, a grid method is used as a modeling method after the optimization obj...
متن کاملCollision-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...
متن کاملFinite Element Analysis of Crack Welding Process
The numerical simulation of the crack welding process is reported in this paper. The thermo-electro-structural coupled-field finite element analysis is adopted to investigate the welding process of crack surfaces. In the simulation, the pressure-dependent and temperature-dependent electrical contact conditions are considered. From the results, the crack surfaces can melt and weld together under...
متن کاملElement free Galerkin method for crack analysis of orthotropic plates
A new approach for analyzing cracked problems in 2D orthotropic materials using the well-known element free Galerkin method and orthotropic enrichment functions is proposed. The element free Galerkin method is a meshfree method which enables discontinuous problems to be modeled efficiently. In this study, element free Galerkin is extrinsically enriched by the recently developed crack-tip orthot...
متن کاملLASER WELDING - Literature Review
Lasers are now being used in the automotive industry to produce seam or stitch welds, as alternatives to conventional resistance spot welding, which are used extensively for attaching auto-body panels to subassemblies. The advantages of laser welding over resistance spot welding result from the smallness of the laser spot size, the large penetration depth of the weld into the material and the r...
