Laser Beam Welding Quality Control

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.

Laser beam welding quality control.

Process for quality control of laser beam welding and cutting download pdf info publication number us5272312a. 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. 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. 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.

Electron beam welding machines are engineered for high performance with advanced computer controls data logging and beam control. 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. In the powder bed process one of the most common methods used in 3d metal printing a laser beam passes through a layer of metal beads and welds them together. The monitoring process developed at empa can be used not only for laser welding but also for quality control of 3d printed metal parts.
