Haɗu da yanayi daban-daban don walda laser

Tare da high dace, high daidaici, babban waldi sakamako, sauki atomatik hadewa, da sauran abũbuwan amfãni, Laser waldi ne yadu amfani a daban-daban masana'antu da kuma taka muhimmiyar rawa a karfe waldi masana'antu samar da masana'antu, ciki har da a cikin soja, likita, Aerospace, 3C. sassa na mota, karfen takarda na inji, sabon makamashi, kayan aikin tsafta, da sauran masana'antu.

Duk da haka, duk wata hanyar walda idan ba a ƙware ƙa'idarta da fasaha ba, za ta samar da wasu lahani ko najasa, walƙiyar Laser ba banda. Kawai fahimtar waɗannan lahani, da kuma koyon yadda za a guje wa waɗannan lahani, don mafi kyawun wasa da darajar walƙiya ta Laser, sarrafa kyakkyawan bayyanar, da samfuran inganci masu kyau. Injiniyoyin ta hanyar tarin gwaninta na dogon lokaci, sun taƙaita wasu lahani na walda na gama gari na mafita, don ma'anar abokan aikin masana'antu!

1.Kkara

A fasa samar a Laser ci gaba waldi ne yafi zafi fasa, kamar crystallization fasa, liquefied fasa, da dai sauransu Babban dalilin shi ne cewa weld samar da babban shrinkage karfi kafin cikakken solidification. Yin amfani da mai ciyar da waya don cike wayoyi ko dumama guntun karfe na iya rage ko kawar da tsagewar da aka nuna a lokacin waldawar Laser.

2. Pores a cikin walda

Porosity shine lahani mai sauƙi a cikin waldawar laser. A kai a kai dakin walda na Laser yana da zurfi kuma kunkuntar, kuma karafa yawanci suna gudanar da zafi sosai da sauri. Gas ɗin da aka samar a cikin ruwa narkakkar ruwa ba shi da isasshen lokacin tserewa kafin ƙarfen walda ya huce. Irin wannan yanayin yana da sauƙi don haifar da samuwar pores. Amma kuma saboda yankin zafi na walda na Laser ƙananan ne, ƙarfe zai iya kwantar da hankali da sauri, sakamakon porosity da aka nuna a waldawar Laser gabaɗaya ya fi na gargajiya Fusion waldi. Tsabtace da workpiece surface kafin waldi iya rage hali na pores, da kuma shugabanci na hurawa kuma zai shafi samuwar pores.

3. Fashewa

Idan ka weld da karfe workpiece da sauri, da ruwa karfe bayan ramin nuni zuwa tsakiyar weld ba shi da lokacin da za a sake rarraba. Solidifying a bangarorin biyu na weld zai haifar da cizo. Lokacin da tazarar da ke tsakanin sassa biyu na aiki ya yi yawa, ba za a sami isasshen narkakkar ƙarfe don yin caulking ba, wanda kuma cizon walda zai faru. A karshen matakin walda na Laser, idan makamashi ya ragu da sauri, ramin yana da sauƙin rugujewa kuma yana haifar da lahani na walda iri ɗaya. Kyakkyawan ma'auni mai ƙarfi da saurin motsi don saitunan walda na laser na iya magance haɓakar haɓakar cizon baki.

4.Kasa

Fasasshen walƙiya ta hanyar walda laser yana da matukar tasiri ga ingancin walda kuma yana iya lalata da lalata ruwan tabarau. Rarraba yana da alaƙa kai tsaye da ƙarfin ƙarfin, kuma ana iya rage shi ta hanyar rage ƙarfin walda da kyau. Idan shigar bai isa ba, ana iya rage saurin walda.

5.Rushewar tafkin narkakkar

Idan waldi gudun ne jinkirin, narkakkar pool ne babba da fadi, da narkakkar adadin karuwa, da kuma surface tashin hankali da wuya a kula da nauyi ruwa karfe, weld cibiyar zai nutse, forming rushewa da rami. A wannan lokacin, ya zama dole don rage yawan makamashin da ya dace don kauce wa rushewar tafkin narkakken.
