Seam welding is a variation of spot welding. In resistance seam welding, the electrodes are actually motor driven wheels which roll over the part creating a “rolling spot” seam. This process is most often used to join two sheets of metal together. In laser seam welding, the part is moved or rotated under the laser allowing the laser […]
What is hermetic sealing? Hermetic Sealing is a variation of the seam sealing process which results in a closed package, completely sealed against ambient atmosphere, preventing the entry or escape of air. The hermetic sealing process is most often employed in the manufacture of electronic devices. Part design and fit up is critical in these […]
Laser welding is a non-contact process which requires access to the weld zone from only one side of the parts being welded. Lasers produce high intensity beam of light which, when focused into a single spot, provides a concentrated heat source, allowing narrow, deep welds and fast welding speeds. Laser welding is frequently used in […]
