Heat conduction welding is characterized by low exposure depths of maximal one millimeter, and is mainly used for joining sheets with low material thickness. With heat conduction welding, the laser melts the sheets along the intended joint. The melts of the joint partners merge together and then cool off to the actual welding seam. Thus, hose connections can be realized more quickly and with lower material distortion than with usual welding methods. Additionally, smooth and pore-free welding seams are created that do not need any post-processing. This makes heat conduction welding, especially in visible areas, the method of choice.
Diode lasers’ process advantages
Laserline's diode lasers optimize heat conduction welding in a number of ways. The uniform power output and homogeneous intensity distribution (top-hat beam profile) guarantee excellent seam qualities and high process stability. Additionally, there are enormous economical advantages: with a lifetime of more than 30,000 operating hours, in addition to high efficiency and low maintenance effort, Laserline's diode lasers are clearly superior to other available beam sources.
