Differentiate between ebw and lbw
WebFeb 17, 2015 · An EBW gun functions similarly to a TV picture tube. The major difference is that a TV picture tube continuously scans the surface of a luminescent screen using a low intensity electron beam to produce a picture. An EBW gun uses a high intensity electron beam to target a weld joint. The weld joint converts the electron beam to the heat input ... WebLaser beam welding (LBW) is a welding technique used to join pieces of metal or thermoplastics through the use of a laser.The beam provides a concentrated heat source, allowing for narrow, deep welds and high …
