“…Robots are modelled as structured objects containing link geometries along with forward and inverse kinematics routines (Ames et al, 2005). Derivation of the dynamic (forces and moments causing motion) model of a manipulator plays a key role for the simulation of motion, analysis of manipulator structures and design of control algorithms.…”

Purpose – The purpose of this paper is to review the progress made in arc welding automation using trajectory planning, seam tracking and control methodologies. Design/methodology/approach – This paper discusses key issues in trajectory planning towards achieving full automation of arc welding robots. The identified issues in trajectory planning are real-time control, optimization methods, seam tracking and control methodologies. Recent research is considered and brief conclusions are drawn. Findings – The major difficulty towards realizing a fully intelligent robotic arc welding system remains an optimal blend and good understanding of trajectory planning, seam tracking and advanced control methodologies. An intelligent trajectory tracking ability is strongly required in robotic arc welding, due to the positional errors caused by several disturbances that prevent the development of quality welds. An exciting prospect will be the creation of an effective hybrid optimization technique which is expected to lead to new scientific knowledge by combining robotic systems with artificial intelligence. Originality/value – This paper illustrates the vital role played by optimization methods for trajectory design in arc robotic welding automation, especially the non-gradient approaches (those based on certain characteristics and behaviour of biological, molecular, swarm of insects and neurobiological systems). Effective trajectory planning techniques leading to real-time control and sensing systems leading to seam tracking have also been studied.

“…Additionally, the search must produce paths that are as process-optimal as possible in terms of torch pose relative to weld geometry. It is further desired that the planning algorithm be very fast when the planning problem is simple, but able to find solutions for difficult problems when they arise [2].…”

Abstract.Although robotics based flexible automation is an intriguing prospect for small to median enterprises in the era of the global competition, the complexity of programming remains one of the major hurdles limiting its applications. This paper presents an automated offline programming (AOLP) method to address this issue. AOLP is software that automatically plans and programs for a robotic welding system with high Degree of Freedoms (DOFs). It takes CAD model as input, and is able to generate the complete robotic welding code without any further programming effort.

“…And also many researchers suggested that to obtain a constant welding current, the constant distance should be maintained between the electrode and the metal plates. Arlo L. Ames, Elaine M. Hinman-Sweeney, John M. Sizemore [11] discussed about quality of weldment and constraints. He noted that if the parts to be welded are slightly misplaced or if the joint dimensions are not constant along the weld line, the resulting weldment is very poor in quality.…”
