Laser beam welding quality control.

And europe for both precision electron beam and laser beam welding of complex components for medical aerospace defense automotive electronics sensor transportation and commercial industries. Several standards exist for laser weld quality not specifically relevant the most relevant en iso 13919 2 2001 welding electron and laser beam welded joints guidance on quality levels for imperfections part 2 relates to electron and laser beam welding of aluminium alloys. Laser welding is fast becoming the preferred technique for joining various materials together and plastics are no exception. Laser 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 welding rates.

Electron beam engineering provides services throughout the u s a. Superior weld quality higher quality control and the ability to join complex shapes are just some of the features that make laser plastic welding a standout option for numerous industries. The monitoring process developed at empa can be used not only for laser welding but also for quality control of 3d printed metal parts. The process is frequently used in high volume applications using automation as in the automotive industry it is based on keyhole or penetration mode welding.
