Chikonzero chikuru nei weld yemuchina welaser welding wakasviba zvakanyanya kazhinji nekuda kweiyo isiriyo yekuyerera kwemhepo kana kusakwana kuyerera kweanodzivirira gasi, izvo zvinoita kuti zvinhu zvive oxidize mukusangana nemhepo panguva yewelding uye inoita dema oxide. ,
Kugadzirisa dambudziko revatema welds mune laser welding michina, anotevera matanho anogona kutorwa:
1. Gadzirisa kuyerera uye kwakananga gasi rinodzivirira: Ita shuwa kuti kuyerera kwegasi rinodzivirira rakakwana kuvhara nzvimbo yese yewelding uye kudzivirira okisijeni mumhepo kuti isapinda muweld. Iyo yekuyerera kwemhepo gasi rinodzivirira inofanira kupesana negwara rebasa rekushanda kuti ive nechokwadi chekuparadzaniswa kwemhepo.
2. Natsiridza mabatirwo epamusoro pezvinhu: Usati waputira, shandisa zvinonyungudutsa zvakaita sedoro uye acetone kunyatsochenesa pamusoro pechinhu chacho kubvisa mafuta uye oxide firimu. Kune zvinhu zviri nyore oxidized, pickling kana alkali washing zvinogona kushandiswa pretreatment kuderedza pamusoro oxides.
3. Gadzirisa ma parameter e-laser: Seta simba relaser zvine musoro kuti udzivise kupisa kwakanyanya. Kuwedzera kumhanyisa kumhanya, kuderedza kupisa kupinza, uye kudzivirira zvinhu kubva pakupisa. Shandisa pulsed laser welding kuti uwane yakanyatsojeka kupisa kwekuisa kudzora nekugadzirisa pulse upamhi uye frequency.
4. Kuvandudza nharaunda yewelding: Chenesa nzvimbo yekushandira nguva nenguva kudzivirira guruva uye hunyoro kupinda munzvimbo yewelding. Kana mamiriro achibvumidza, shandisa yakavharwa welding midziyo yekuisa parutivi tsvina yekunze.
Nzira dziri pamusoro apa dzinogona kuderedza zvinobudirira dambudziko rekusviba kwekushongedza seams uye kunatsiridza welding mhando uye kugona.
