The laser ịgbado ọkụ igwe nwere ike ọ bụghị naanị mma ọrụ arụmọrụ, kamakwa onye ahụ nke okokụre workpiece mara mma, na Weld bụ obere, na ịgbado ọkụ omimi bụ nnukwu, na ịgbado ọkụ quality dị elu. Olee otú iji hụ na ịgbado ọkụ àgwà nke laser ịgbado ọkụ igwe, N'eziokwu, ọtụtụ ihe-emetụta àgwà nke laser ịgbado ọkụ, ka anyị chọpụta.
1. The ike nke a laser usu
The ike nke laser usu: na-ezo aka na kacha mmepụta ike nke a otu laser usu, na unit bụ J (Joule). Nke a bụ isi ihe na oke nke laser, nke na-ekpebi karịa ike na laser nwere ike na-emepụta. Dị ka ojiji nke ebu idozi, na laser ike nwere ike izute mkpa nke ọ bụla oge n'okpuru 70J, na nnukwu ike bụ na-efu, ma ọ bụ fundamentally bụghị-eji, na-abawanye na olu nke laser ike ọkọnọ na olu nke okpomọkụ sink ebelata arụmọrụ nke ike ọkọnọ.
2. Laser doo ntụpọ n'obosara
Laser ntụpọ na-elekwasị anya n'obosara: Nke a bụ nnọọ mkpa oke na-egosipụta imewe arụmọrụ nke laser, na nkeji nke (mm), nke na-ekpebi ike njupụta na nhazi nso nke laser. Ọ bụrụ na ngwa anya imewe nke laser bụ ihe ezi uche na elu, na laser ike na-lekwasị, na-elekwasị anya bụ ezi, na laser ntụpọ n'obosara nwere ike na-achịkwa na nso nke 0.2mm-2mm. Ma na-elekwasị anya dayameta nke laser pụrụ ịchịkwa na 0.2mm bụ a siri otu maka laser generator. ule. Lasers n'ozuzu e mere na China, n'ihi na ha chọrọ naanị iji belata na-eri, ya mere, na laser nhazi nke ngwaọrụ bụ na mfe, imewe bụ bụghị rigorous, na laser bụ dịgasị iche na uji eze, na-akpata ihe isi ike na ezi na-elekwasị anya, na laser ntụpọ dayameta nke laser mmepụta bụ bụghị ruo ọkọlọtọ. Ọ kwuru na-abụ 0.2mm, ma nwere ike na-eru a kacha nta nke 0.5mm. N'ihi na divergence nke laser, na mmepụta laser doo nwere ike ịbụ na a mgbe nile okirikiri udi, nke na-akpata ahụ n'ezie irradiation ebe nke the laser to be too large and ablation of the weld seam. That is, unnecessary laser irradiation occurs at both ends of the weld to cause the two ends of the weld to be concave. This phenomenon is particularly serious for repairing the already polished mold, and sometimes even scraps the mold. The company's lasers are well-designed, with strict material selection and careful debugging, so that the beam spot diameter of the laser output can be precisely monitored, so that the size of the focused spot can be as small as 0.2mm and can be in the range of 0.2mm and 2mm. Carry out stepless adjustment to reach the international advanced level.
3. The ugboro nke laser usu
Ugboro nke laser usu: Nke a bụ ikike nke igosipụta otú ọtụtụ pulses na laser nwere ike ime ka na otu abụọ, na nkeji nke (Hz). Mbụ niile, ọ ga-ahụ kwuru na ịgbado ọkụ metal bụ ike nke na-eji laser, na na ikpe nke mgbe nile na-laser ike, na elu ugboro ole, ndị nta na ike nke ọ bụla laser mmepụta. Ya mere, anyị kwesịrị iji hụ na ike nke laser bụ zuru ezu iji agbazekwa metal. N'ihe banyere nhazi ọsọ, na mmepụta ugboro nke laser nwere ike kpebisiri ike. N'ihe banyere laser-rụziri egweri ngwaọrụ, 15 Hz nwere ike izute mkpa nke ịgbado ọkụ. Elu gabiga ókè ugboro ole ga-apụghị izere ezere ime ka usu ike nke laser na-adị oke ala, dapụtara na ịgbado ọkụ ọdịda.
4. The usu waveform nke laser na ikwu ìhè absorption ọnụego nke ihe na-welded
Usu waveform nke laser: N'ihi pulsed laser nhazi, laser usu waveform bụ ihe dị mkpa nke na pulsed laser ịgbado ọkụ. Mgbe a elu-osisi ike laser bụ merenụ n'elu nke ihe onwunwe, na-metal n'elu na-egosipụta 60% na 98% nke laser ike, na reflectance dịgasị na n'elu okpomọkụ. Ya mere, reflectivity nke laser na itinye n'ọrụ ọnụego nke laser dị iche maka iche iche ọla. Ịrụ irè ịgbado ọkụ, ọ dị mkpa ka input lasers nke dị iche iche waveforms, nke mere na metal Ọdịdị na Weld nwere ike crystallized na otu ezigbo n'ụzọ na-etolite a matriks. A na-agbanwe agbanwe metal Ọdịdị nwere ike na-etolite a elu àgwà Weld. The n'ozuzu anụ ụlọ ígwè ọrụ na-eji ọnụ ala otu-efegharị efegharị laser ike. Ya mere, ịgbado ọkụ bụ obere mgbanwe, ọ bụ ike imeghari ka ịgbado ọkụ nke dị iche iche ebu ihe, na mgbe rework a rụrụ, nke ukwuu n'efu oge ịgbado ọkụ ihe na nwere ike ime ka Ebu. hapụrụ. Dị iche iche metal ihe dị iche iche degrees nke echiche na absorption nke laser ìhè, na otu laser ga-emepụta dị iche iche ịgbado ọkụ na mmetụta na-dị iche iche ọla, na-emetụta ya penetration, ịgbado ọkụ na-agba, crystallization ọsọ na ekweghị ekwe, otú a otu akụkụ anọ fee ịgbado ọkụ anaghị edozi ahụ chọrọ nke dị iche iche ebu metal ịgbado ọkụ.
