Abstract
It is shown that welding of low-carbon steels using radiation of CO₂-laser in a pulsed-periodic mode (PPM) produces more narrow and deeper welds that in a continuous mode at a power of radiation equal to an average power of PPM. At optimum frequency of pulses the structure of the weld root part becomes more regular, the HAZ width is decreased, overheating (coarse-grained) region is either absent or becomes not clearly defined.
Keywords: laser welding, CO2-laser, continuous radiation, pulsed-periodic radiation, low-carbon steels, geometry of welds, strength, structure
