Development of Mash Seam Welder for Preventing Double Deformation at Edge of Lap Seam

Seam-Tracking for Friction Stir Welded Lap Joints

This article presents a method for automatic seam-tracking in friction stir welding (FSW) of lap joints. In this method, tracking is accomplished by weaving the FSW tool back-and-forth perpendicular to the direction of travel during welding and monitoring force and torque signals. Research demonstrates the ability of this method to automatically track weld seam positions. Additionally, tensile ...

Seam Carving with Improved Edge Preservation

In this paper, we propose a new method to adapt the resolution of images to the limited display resolution of mobile devices. We use the seam carving technique to identify and remove less relevant content in images. Seam carving achieves a high adaptation quality for landscape images and distortions caused by the removal of seams are very low compared to other techniques like scaling or croppin...

Three Dimension Curve Welding Seam Modeling for Seam Tracking

A novel modeling method for 3D curve welding seam is presented in this paper based on a welding robot for large workpiece. The 3D curve welding seam tracking is implemented by macro and micro motion which can control translational motion of torch in a large range and implement accurate seam tracking in small range. As such, the self-teaching seam model and real-time seam model are established t...

Constraining Surface Deformation Predictions Resulting from Coal Seam Gas Extraction

Literature at the Human-Computer Seam

Some of the technology-generated changes may not have a measurable effect on the end literary product: despite the lamentations of many writers, it is not clear whether the physical act of writing on a word processor truly changes the written document. In the same vein, though it is astonishing that a book can be written in the United States, edited in Switzerland, typeset in India, and proofre...
