Laser Welder Work Principle
A na-emepụta ọkụ laser n'ime kristal ruby. Ihe kristal ruby bụ nke aluminom oxide na chromium gbasasịrị n'ime ya. Nke na-akpụ banyere 1/2000 nke kristal, nke a na-erughị ruby eke. A na-etinye enyo ndị nwere ọla ọcha n'ime n'akụkụ abụọ nke kristal. Otu akụkụ enyo nwere obere oghere, ahịhịa na-esi na oghere a pụta.
A na-etinye tube na-egbuke egbuke gburugburu kristal ruby, nke jupụtara na gas inert xenon. Emebere ọkụ ahụ nke ọma dị ka nke a na-eme ka ọ̀tụ̀tụ̀ ọkụ dị ihe dị ka puku na-egbuke egbuke kwa sekọnd.
A na-agbanwe ike eletrik ka ọ bụrụ ike ọkụ, nke a na-arụ ọrụ site na tube flash.
A na-enye capacitor maka ịchekwa ike eletriki ma nye nnukwu voltaji na tube ọkụ maka ịrụ ọrụ nke ọma.
Ike eletrik na-apụ na capacitor na xenon na-agbanwe ike dị elu ka ọ bụrụ ọkụ ọkụ na-acha ọcha nke 1/1000 kwa sekọnd.
Atọm chromium nke kristal ruby nwere obi ụtọ ma tinye ya n'ime ike dị elu. N'ihi okpomọkụ na-emepụta ụfọdụ ike a na-efunahụ. Mana ụfọdụ ike ọkụ na-egosipụta enyo na-enyo enyo, atom chromium ọzọ na-enwekwa obi ụtọ ruo mgbe ha nwekwuru ike ha n'otu oge iji mepụta ìhè dị warara. Nke a na-apụta site n'obere oghere nke enyo kristal.
A na-elekwasị anya na oghere a dị warara site na oghere anya na-elekwasị anya iji mepụta obere ọkụ laser siri ike n'elu ihe a na-arụ ọrụ.
Igwe ọkụ laser na-agbanwe mgbe ya na ihe na-emekọrịta ihe
Mmụba ike Laser nke ihe dị iche iche dabere n'ọtụtụ ihe, dị ka ogologo wavelength, ọkpụrụkpụ ihe, nhazi kristal, ihe mgbakwunye ihe, nhazi molecular, na ndị ọzọ. Usoro a na-ewe uru nke ihe onwunwe ndị a na laser iji mepụta njikọ n'etiti ihe plastik 2-nke na-ebufe ike laser na nke na-amịkọrọ ya.
Mgbe eriri laser na-ezute ihe ọ bụla dị ka plastik, a ga-ebufe ya, gosipụta ya, ma ọ bụ tinye ya n'ime ya dabere n'ogologo ogologo na nhazi nke ihe ọ na-ezute. Ọtụtụ ihe na-egosipụta ogo ụfọdụ nke mmetụta 3 niile, mana n'ụzọ dị iche iche. Ihe nwere ike doo anya na ìhè na ụdịdị dị iche iche a na-ahụ anya ma na-adọrọ adọrọ na laser infrared, ma ọ bụ bụrụ ihe na-adịghị mma n'anya anyị mana ọ na-apụta ìhè na laser infrared.

Laser ịgbado ọkụ bụ usoro nke na-emepụta coalescence nke ihe na okpomọkụ na-enweta site na ngwa nke mgbanaka ọkụ na-etinye uche na-adabere n'elu ebe a ga-ejikọta.
A na-enweta ya site na usoro ndị a:
1. Mmekọrịta nke laser doo na workpiece ihe.
2. Okpomọkụ conduction na okpomọkụ ịrị elu.
