Kedu ihe bụ Welding Laser?

Laser ịgbado ọkụ bụ ụdị ịgbado ọkụ, na-eji laser doo dị ka a ịgbado ọkụ ọkụ isi iyi, ịgbado ọkụ ụkpụrụ bụ site a kpọmkwem usoro na-akpali ndị nọ n'ọrụ ọkara, na-akpụ resonant oghere oscillation, na mgbe ahụ na-agbanwe n'ime kpaliri radieshon doo, mgbe doo anya. na mpempe ọrụ na-akpọtụrụ ibe ha, ike na-etinye ike site na mpempe ọrụ, mgbe okpomọkụ ruru ebe mgbaze nke ihe nwere ike welded.

Dị ka isi usoro nke ịgbado ọkụ ọdọ mmiri, laser ịgbado ọkụ nwere abụọ isi ịgbado ọkụ usoro: okpomọkụ conduction ịgbado ọkụ na miri penetration (keyhole) ịgbado ọkụ. The okpomọkụ eme site okpomọkụ conduction ịgbado ọkụ na-diffused na-arụ ọrụ ibe site okpomọkụ nyefe, nke mere na weld elu na-agbaze, ọ dịghị vaporization kwesịrị ime, nke a na-ejikarị na ịgbado ọkụ nke ala-ọsọ mkpa-ish components. Ngwakọta dị omimi na-agbado ọkụ na-ekpochapụ ihe ahụ wee mepụta nnukwu plasma. N'ihi okpomọkụ dị elu, a ga-enwe oghere n'ihu ọdọ mmiri a wụrụ awụ. Mgbado ọkụ dị omimi bụ ụdị ịgbado ọkụ laser a na-ejikarị eme ihe, ọ nwere ike ịgbanye mpempe ọrụ ahụ nke ọma, na ntinye ike dị ukwuu, na-eduga na ịgbado ọkụ ngwa ngwa.

Usoro nhazi na ịgbado ọkụ laser

Enwere ọtụtụ usoro usoro nke na-emetụta ogo ịgbado ọkụ laser, dị ka njupụta ike, laser pulse waveform, defocusing, ịgbado ọkụ ọsọ na nhọrọ nke inyeaka echebe gas.

Njupụta Ike Laser

Njupụta ike bụ otu n'ime ihe ndị kachasị mkpa na nhazi laser. Site na njupụta ike dị elu, oyi akwa dị elu nwere ike ikpo ọkụ ruo ebe na-esi ísì ụtọ n'ime microsecond, na-ebute oke vaporization. Ya mere, njupụta ike dị elu bara uru maka usoro iwepụ ihe onwunwe dị ka ịkụ ala, ịkpụ na ihe osise. Maka njupụta ike dị ala, ọ na-ewe ọtụtụ milliseconds maka okpomọkụ dị n'elu iji ruo ebe a na-esi esi mmiri, na tupu elu vaporizes, ala na-erute ebe mgbaze, nke dị mfe ịmepụta ezigbo agbaze weld. Ya mere, n'ụdị okpomọkụ conduction laser ịgbado ọkụ, ike njupụta nso bụ 104-106W / cm2.

Ntugharị ọkụ Laser Pulse Waveform

Laser pulse waveform abụghị naanị ihe dị mkpa maka ịmata ọdịiche dị na mwepụ ihe site na agbaze ihe, kamakwa isi ihe iji chọpụta olu na ọnụ ahịa akụrụngwa nhazi. Mgbe elu ike laser doo na-gbara n'elu nke ihe onwunwe, elu nke ihe onwunwe ga-enwe 60 ~ 90% nke laser ume na-egosipụta na-atụle ọnwụ, karịsịa gold, ọlaọcha, ọla kọpa, aluminum, titanium na ihe ndị ọzọ nwere. ntụgharị uche siri ike na nnyefe ọkụ ngwa ngwa.

Mgbe okpomọkụ dị n'elu nke ihe ahụ na-ebili na ebe mgbaze, ntụgharị uche na-ebelata ngwa ngwa, na mgbe elu dị n'elu ala na-agbaze, ntụgharị uche na-eguzosi ike na ụfọdụ uru.

Ogologo Laser Pulse

Usu obosara bụ ihe dị mkpa oke nke pulsed laser ịgbado ọkụ. Achọpụtara obosara nke pulse site na omimi nke ntinye na mpaghara okpomọkụ emetụtara. Ogologo obosara nke usu ahụ dị, ka mpaghara okpomọkụ emetụtara dị ukwuu, na omimi nke ntinye na-abawanye na ike 1/2 nke obosara usu. Otú ọ dị, mmụba nke obosara pulse ga-ebelata ike kachasị elu, ya mere, a na-ejikarị mmụba nke obosara pulse eme ihe maka ịgbado ọkụ ọkụ, na-eme ka ọkpụkpụ weld dị obosara na nke na-emighị emi, karịsịa kwesịrị ekwesị maka ịgbado n'apata nke obere efere na nnukwu efere. Agbanyeghị, ike kacha elu na-ebute oke ọkụ, na ihe ọ bụla nwere obosara usu kacha mma nke na-ebuli omimi nke ntinye.

Ọnụọgụ Defocus

Ịgbado ọkụ nke laser na-achọkarị ihe nkwụsịtụ, n'ihi na ike njupụta nke ebe etiti na laser lekwasịrị anya dị oke elu, nke dị mfe ikpochapụ ihe ịgbado ọkụ n'ime oghere. Nkesa njupụta ike bụ otu n'otu n'ime ụgbọ elu ọ bụla pụọ na nlebara anya laser.

Enwere ụdị defocus abụọ:
Defocus dị mma na nke na-adịghị mma. Ọ bụrụ na focal ụgbọelu dị n'elu workpiece, ọ bụ nti defocus; ma ọ bụghị ya, ọ bụ defocus na-adịghị mma.
