Dual Beam Laser Welding

Previous studies demonstrated use of dual beam laser processing can delay humping onset to higher speeds and slow down cooling rates.

Dual beam laser welding.

A dual beam laser technique has been used to mitigate pore formation in different alloys such as aluminum galvanized steel dissimilar welding of magnesium aluminum and magnesium steel. Dual beam laser welding with a 20 80 split beam energy ratio provides an improved weld bead quality with respect to porosity. Initial experimental studies showed the dual beam process offered several advantages over the conventional single beam process. In recent years laser beam welding using two laser beams or dualbeam laser welding has become an emerging welding technique.

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. The top surface quality of the weld bead obtained with dual beam laser welding is smoother and more uniform than the quality obtained from single beam laser welding as a result of less humping. Morn handheld fiber laser welding machine also called handheld fiber laser welder portable fiber laser welding machine manual fiber laser welding machine is a new type high power high end continuous welding tool that couples a high energy laser beam into an optical fiber collimates it into parallel light through a collimating lens after long distance transmission and then focuses on the. 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.

A welding technique that combines two high energy beam sources either electron beams or laser beams called dual beam welding has been investigated in recent years. Laser beam welding can be performed out of vacuum. Manipulating power to the inner and outer beams helps reduce spatter while improving weld speed and quality.
