Muenzaniso wekuongorora mashandisirwo e laser welding ane dhayamita dzakasiyana dzepakati

Saizi yedhayamita yepakati pe laser inokanganisa kurasikirwa kwekutumira uye kupararira kwesimba rechiedza. Kusarudzwa kwakanaka kwedhayamita yepakati kwakakosha zvikuru. Dhayamita yepakati yakawandisa inotungamira mukukanganiswa kwemode uye kupararira mukutumira kwe laser, zvichikanganisa kunaka kwemwaranzi uye kurongeka kwekutarisa. Dhayamita yepakati diki kwazvo inokonzera Kuenzana kwesimba re optical re single-mode fiber kunowedzera kuipa, izvo zvisingakodzeri kutapurirana kwelaser ine simba guru.

1. Mabhenefiti uye mashandisirwo ema lasers madiki epakati (<100um)

Zvinhu zvinopenya zvakanyanya: aruminiyamu, mhangura, simbi isina ngura, nickel, molybdenum, nezvimwewo;

()1）Zvinhu zvinopenya zvakanyanya zvinofanirwa kusarudza laser diki ine dhayamita yepakati. Beam re laser rine simba guru rinoshandiswa kupisa zvinhu nekukurumidza kusvika zvanyorova kana kuti zvapfava, izvo zvinovandudza mwero wekunyudzwa kwezvinhu ne laser uye zvinobudirira uye nekukurumidza kugadziriswa. Kusarudza laser ine dhayamita yakakura yepakati kunogona kutungamira nyore nyore kuratidzwa kwakanyanya, zvichitungamira mukuwelda kwechokwadi uye kutopisa laser;

Zvinhu zvinobatwa nematombo: nickel, nickel-plated copper, aruminiyamu, stainless steel, titanium alloy, nezvimwewo.

Chinhu ichi chinowanzoda kudzora zvakanyanya nzvimbo inokanganiswa nekupisa uye dziva diki rinonyunguduka, saka zvakakodzera kusarudza laser diki ine dhayamita yepakati;

Kugadziriswa kwelaser nekukurumidza:

()3）Kupinza kwakadzika kunoda kugadziriswa nelaser nekukurumidza, uye zvakakosha kusarudza laser ine simba rakawanda kuti ive nechokwadi chekuti simba remutsara rakakwana kunyungudutsa zvinhu nekumhanya kukuru, kunyanya pakupinza kwakadzika, kupinza kwakadzika, nezvimwewo, izvo zvinoda kudzika kwakakwirira kwekupinda. Zviri nani kusarudza laser diki yakakodzera dhayamita yepakati.

2. Zvakanakira uye mashandisirwo ema lasers makuru epakati (>100um)

Dhayamita hombe yepakati nenzvimbo hombe, nzvimbo yakakura yekupisa, nzvimbo yakakura yekushanda, uye kunyunguduka kwechinhu chete ndiko kunowanikwa, izvo zvakakodzera kushandiswa mukushandiswa kwelaser cladding, laser remelting, laser annealing, laser hardening, nezvimwewo. Muminda iyi, nzvimbo hombe yechiedza zvinoreva kushanda kwepamusoro uye zvikanganiso zvishoma (thermal conductive welding haina kana zvikanganiso).

Pane zvekusonanzvimbo yakakura inonyanya kushandiswa pakusanganisa zvinhu zvakasiyana-siyana, iyo inoshandiswa pakubatanidza ne laser diki ine dhayamita yepakati: nzvimbo hombe inoita kuti pamusoro pechinhu ichi panyungudike zvishoma, zvichichinja kubva pakuva chakaoma kuita mvura, izvo zvinovandudza zvakanyanya mwero wekunyungudika kwechigadzirwa kuita laser, uye zvinoshandisa core diki. Mukuita uku, nekuda kwekupisa kwenzvimbo hombe, mushure mekugadzirisa, uye tembiricha yakakura inopiwa kudziva rakanyungudutswa, chinhu chacho hachiwanzo pwanyika nekuda kwekupisa nekukurumidza uye kutonhora nekukurumidza. Chinogona kuita kuti chitarisiko che weld chive chakapfava uye chiwane kupararira kwakaderera pane mhinduro ye laser imwe chete.
