Lazerli tolali payvandlash mashinasidan foydalanish bo'yicha maslahatlar

Operatsion jarayoni
Operatsiyadan oldingi-tayyorlik
Uskunani tekshirish: Mashinani yoqishdan oldin lazer generatori, sovutish tizimi, gaz ta'minoti (masalan, argon yoki azot) va elektr uzatish liniyalari normal ishlashiga ishonch hosil qiling. Masalan, sovutish suvi harorati 20-25 daraja orasida nazorat qilinishi kerak; agar suv harorati juda yuqori bo'lsa, u lazerga zarar etkazishi mumkin. Gaz bosimi 0,5-0,8 MPa da barqaror bo'lishi kerak, chunki bosimning etarli emasligi himoya gazining ishlashiga ta'sir qiladi.

Ish qismini joylashtirish: Bo'shliqni ta'minlash uchun dastgohlarni payvandlash talablariga muvofiq sozlang Yupqa plastinka payvandlash uchun 0,1 mm dan kam yoki teng yoki qalin plastinka payvandlash uchun 0,3 mm dan kam yoki teng. Juda katta bo'shliq uzluksiz choklarga olib keladi. Noto'g'ri shakldagi ish qismlari uchun ularni mahkamlash va payvandlash paytida harakatlanishni oldini olish uchun maxsus moslamalardan foydalaning.

Parametr sozlamalari: Boshqarish paneli orqali payvandlash parametrlarini kiriting, jumladan lazer quvvati (odatda 500-5000 Vt, material qalinligidan kelib chiqqan holda sozlanadi), impuls chastotasi (1-200 Hz), impuls kengligi (0,1-20 ms), payvandlash tezligi (0,5-10 m/min) va hokazo. 800-1200 Vt gacha va tezligi 2-3 m / min gacha.

Payvandlash operatsiyasi
Focus Adjustment: Adjust the laser focal point according to the workpiece thickness. For thin plates (≤1 mm), set the focus 0.1-0.3 mm above the workpiece surface (positive defocus) to enlarge the spot diameter. For thick plates (>1 mm), penetratsiyani kuchaytirish uchun fokusni ish qismi yuzasidan 0,1-0,3 mm pastga (salbiy defokus) o'rnating.

Start Welding: After pressing the start button, the laser beam moves along the preset path while the protective gas is released simultaneously. Keep your hands steady during operation to avoid weld deviation. For long welds (>50 mm), mahalliy qizib ketishning oldini olish uchun har bir segmentni 20-30 mm ga 1-2 soniya oralig'ida nazorat qilib, segmentlarda payvandlash tavsiya etiladi.

Jarayon monitoringi: Ko'rish oynasi yoki kamera orqali real vaqtda payvand shaklini kuzatib boring. Agar teshiklar yoki yoriqlar kabi nuqsonlar yuzaga kelsa, darhol payvandlashni to'xtating va parametrlarni sozlang. Masalan, teshiklar odatda materialdagi gazdan himoyalanish yoki sirt moyining etarli emasligi tufayli yuzaga keladi, shuning uchun gaz oqimini tekshiring yoki ish qismini tozalang.
