Welding Laser da Electron Beam Welding: "High-Tech" don Ƙarshen Ƙarshen Ƙarshe

A cikin manyan filayen kamar sararin samaniya da microelectronics, walda na al'ada na al'ada yana da wahala don biyan buƙatun daidaici da zurfin shiga. Laser walda da lantarki katako waldawa tsaya a waje tare da abũbuwan amfãni daga "high makamashi yawa, high daidaici, kuma low nakasawa."

Welding Laser:Yana amfani da katako mai ƙarfi na Laser (tsawon tsayin 1064nm ko 10.6μm) wanda aka mayar da hankali kan farfajiyar aikin. Yanayin zafin jiki na nan take zai iya kaiwa sama da 10,000C, yana ganin saurin narkewa da haɗuwa da karafa. Yana da kunkuntar walda da ƙananan wuraren da zafi ya shafa, yana mai da shi dacewa da walda kayan ɓangarorin bakin ciki da ƙananan sassa, kamar madaidaicin kyamarar wayar hannu da injin injin iska.

Wutar Lantarki na Wuta:A cikin wani yanayi mara amfani, wutar lantarki tana haɓakawa kuma ana mai da hankali don yin bam da kayan aikin. Tare da yawan makamashi mai girma kamar 10 ^ 6-10 ^ 8 W / cm², zai iya cimma zurfin shigar waldi tare da rabon al'amari na har zuwa 10: 1. Ya dace da daidaitattun abubuwan da ke da kauri mai kauri kamar sassan injin nukiliya da manyan gears. Koyaya, yana da tsadar kayan aiki kuma yana buƙatar yanayi mara kyau, yana haifar da ƙayyadaddun yanayin aikace-aikacen.

Haɗin Kayan Aiki & Nau'in Laser

Daidaitaccen tsarin waldawar Laser ya ƙunshi sassa uku masu mahimmanci:

Laser Generator: Yana canza makamashin lantarki zuwa katakon Laser mai daidaituwa.

Tsarin Watsawa na gani: Jagora da mai da hankali kan katako (misali, fiber optics, madubai masu nuni).

Wurin aiki: Yana haɗa kayan aiki, sarrafa motsi (robots/matakan layi), da isar da iskar gas mai karewa.

Ma'auni Mai Mahimmanci & Ka'idojin Aiki

Sarrafa sigina kai tsaye yana ƙayyade ingancin walda-har ma da ƙananan ƙetare na iya haifar da lahani kamar porosity ko fasa:

(1) Pre-Welding Preparing

Tsaftace Abu: Cire mai, sikelin oxide, ko sutura ta amfani da ethanol ko fashewar yashi. Don kayan haɓakawa mai ƙarfi (Al, Cu), riga-kafi da saman don rage tunanin Laser.

Matsayi mai da hankali: Yi amfani da defocus mara kyau (mayar da hankali a ƙasa da saman workpiece) don shiga mai zurfi; tabbatacce defocus (mayar da hankali a sama) don bakin ciki zanen gado don kauce wa ƙona-ta.

Aikace-aikacen Masana'antu & Nazarin Harka

Canjin walda na Laser yana haifar da sabbin abubuwa a cikin sassan:

(1) Gine-gine & Manyan Masana'antu

Tsarin Karfe: Tsarin walƙiya na Laser-arc matasan 20mm+ T-beams a 1.2m/min, rage nakasawa da 50%.

Ginin Jirgin Ruwa: Tsarin jagorar Robot tare da rails na axis na 7 suna walda faranti mai kauri mai kauri 115mm a cikin fasfo guda, yana magance ƙalubalen "welding-gefe guda, kafawar gefe biyu".

(2) Kera Motoci

Daidaitaccen walda na abubuwan watsawa ta amfani da "fasahar kula da kwanciyar hankali na maɓalli" don cimma waldi mara lahani mara lahani.

Laser tela-welding na bangarori na jikin mota yana rage ƙidaya kashi 30% da nauyi da 15%.

(3) Babban Makamashi & Aerospace

Makamashin Nukiliya: Fiber Laser waldi na Ni-28W-6Cr gami (don 850°C narkakkar ruwan gishiri)

Aerospace: Welding na titanium gami injin ruwan wukake tare da ƙaramin yankin da zafi ya shafa (HAZ) don adana ƙarfin abu.
