Abstract

Sposób spawania laserowego spoin czołowych i pachwinowych złączy wymienników ciepła charakteryzuje się tym, że ogniskuje się wiązkę laserową na głębokości 65% - 68% grubości blachy i prowadzi wymuszoną modulację wiązki z częstotliwością 50 ÷ 55 kHz w zakresie mocy od 0 do nastawionej wartości maksymalnej.The method of laser welding of butt and fillet welds of heat exchanger joints is characterized by the fact that the laser beam is focused at a depth of 65% - 68% of the sheet thickness and conducts forced beam modulation at a frequency of 50 ÷ 55 kHz in the power range from 0 to the set maximum value.
