Robotic welding

Robotic welding mounts a GMAW or laser torch on an articulated arm that follows a programmed path with seam tracking, used on yard panel lines to weld stiffeners and web frames to flat panels at high speed and consistent quality. Off-line programming from the 3D ship model and through-arc or laser seam tracking handle plate fit-up variation. Robots cut welder fatigue and hold leg length and travel speed tight, which limits distortion. The economic case fits the repetitive geometry of stiffened-panel and grand-block assembly; complex erected joints stay manual. Procedures still qualify to the same WPS and the operator holds an ISO 14732 mechanized-welding qualification.
