Argon arc walda za a iya amfani da mobile walda hayaki mai tsabtace, a lokaci guda, dole ne a tabbatar da walda tashar gida iska mai kyau don tabbatar da lafiyar walda.
1.5 bugun jini walda:
Pulse walda ne na walda walda walda, shi ne walda hanyar amfani da sarrafa bugun jini fasahar, da biyu m gudanar da wutar lantarki (girman arc wutar lantarki da kuma bugun jini wutar lantarki) don walda walda. Pulse walda zai iya samar da kwanciyar hankali kananan rami sakamako, tabbatar da walda permeability da kuma inganta narkewa spreading rate don argon arc walda. Welding ƙura analysis ne iri ɗaya da argon arc welding.
1.6 Plasma walda:
Plasma walda ne na walda na walƙiya arc, shi ne hanyar walda ta hanyar high mayar da hankali plasma beam (jet gudun har zuwa 300 ~ 2000m / s, makamashi yawa har zuwa 105 ~ 106W / cm2) arc narkewa motherboard. High walda sauri na plasma walda, ba za a iya buɗe slopes, walda walda aiki mai kyau, walda walda zafi tasiri yankin karami, walda karkatarwa da ragowar damuwa karami, za a iya walda daban-daban karfe, musamman ga kauri 3 ~ 8mm kayan, shi ne mai inganci inganci low kudin arc walda fasaha.
Gas mai tsabta yana amfani da argon mai tsabta, gas mai karewa yana da Argon da Helium, wasu suna da ƙananan adadin hydrogen. Welding ƙura analysis ne kama da argon arc walda.
Welding bitar gurbataccen iri da yawa, ya kamata a hada da gudanarwa daga gurbataccen tushen, hanyar gudanarwa, sirri kariya 3 bangarori. Gudanar da gurɓataccen yanayi ya kamata ya tsara tsari tare da takamaiman yanayin tashar, wanda ba zai iya rabuwa da ainihi ba, yana shafar aikin samarwa na al'ada. Tsarin tsarin gudanarwa ya kamata ya yi la'akari da hanyoyin gudanar da gurɓataccen yanayi daban-daban a ƙarƙashin tabbatar da sakamakon sarrafawa, an tsara shi ta hanyar haɗin kayan aiki da kayan aiki don rage amfani da wuri da adana zuba jari.
Yi ingantattun matakan fitar da taba daga iska
Air fitar da hayaki ne wani muhimmin mataki na kula da walda hayaki. A halin yanzu a cikin gida da kasashen waje da aka dauki iska fitar da taba matakan ne mafi girma: maki fitar da taba, gida fitar da iska, dukan gida iska canji, dukan gida iska tsabtace da sauran hanyoyi da dama
1) Matsayin shan taba
Point fitar da hayaki ne kai tsaye daga walda arc yankin kusa da kawar da walda hayaki gas, Point fitar da hayaki nau'i: Akwai babban iska yawan low matsin lamba tsarin, kananan iska yawan high matsin lamba tsarin, mobile walda hayaki tsabtace inji da sauransu. A point fitar da taba irin na'urar iska da iska gudun dole ne ya dace, iska yawan ma ƙananan ba za a iya pump fita, iska yawan ma taro sa kare yanayi da aka lalata, da kuma tasiri walda inganci. Lokacin da ake amfani da taba mai fitarwa, kare amfani da gas ya kamata ya ƙaru daidai
2) Local fitar da iska
Local iska fitarwa ne kai tsaye daga walda maki shan hayaki gas, akwai iska rufi, bushewa irin, burrow fitarwa irin da dai sauransu. Wannan hanyar da aka yi amfani da shi ne mafi ƙananan walda workpieces, walda tashar mafi m, ko motsi a cikin ƙananan kewayon, a kan bita tashar babu wani crane. Duba hoto na 4 da kuma 5.
Na gida bushewa nau'i ne yafi ga wani gefen bushewa gashi, wani gefen bushewa iska fitar da taba hanyar da aka yi amfani da ciki walda na rufe kwantena tare da rami biyu. A lokacin manyan kwantena masana'antu, fitar da taba iska aikace-aikace ne mafi fadi ga walda ma'aikata a cikin kwantena.
Ana amfani da na'urar fitar da hayaki a ƙarƙashin teburin kamar gas yankan inji, kwanan nan an yi amfani da teburin yankan ruwa don tattara plasma yankan hayaki don tsabtace iska.
3) duk dakin iska
Welding bita cika wadannan yanayi, dole ne a dauki dukan dakin iska:
A waldi tashar ba za a iya gyara, ba za a iya amfani da maki taba fitarwa da kuma gida taba fitarwa hanyar;
B kawai wani ɓangare na walda tashar da kadan taba fitarwa da kuma gida fitarwa hanyar, ba zai iya tabbatar da dakin aiki na hayaki mataki ya kasance a cikin izini.
Manufar dukan ɗakin iska shine: gabatar da iska mai kyau a waje don fading matattarar walda hayaki gas a cikin gida iska, don sa matsakaicin matattarar walda hayaki gas a wurin aiki ya sarrafa a ƙasa da ƙa'idodin da aka yarda. Daga hangen nesa na daidaitaccen iska, yawan iska mai kyau da ake buƙatar gabatarwa dole ne a cire yawan iska mai ciki da ke ƙunshe da walda hayaki, don haka ci gaba da gabatar da iska mai kyau, gurbataccen iska mai ciki ya ci gaba da cirewa, don haka kawar da hayakin walda da ke ci gaba da samarwa a cikin gida.
