Welding is an art and a science, but sometimes things go wrong, and defects appear on the surface or inside, making the weld weak or strong. Some defects are caused by human error, others by material or machine, but all defects can be fixed or avoided with proper technique and routine. ...
At high current and welding speed the shear force of the plasma on the free surface determines the flow of liquid metal under the arc. This causes the weld pool under the arc to turn into a thin liquid film. In this situation, the arc force acts almost directly over the melting ...

In ceramic injection molding, a welding defect generated by the joining of melt fronts is a typical molding defect. The surface of the flow front becomes rough and sometimes voids are generated in it [1], [2], [3]. These defects may remain in a product as a void and/or a crack at...

To address this problem, we proposed a 3D vision-based aluminum reservoir welding surface defect detection method. First of all, a scanning system based on laser line scanning camera was constructed to acquire the point cloud data of weld seams on the aluminum reservoir surface. Next, a planar...
