Ukuqaliswa kweNozzle
Imilomo isoloko isisixhobo sokuwelda esingahoywayo kwimisebenzi ye-welding.Kwinkqubo yenkonzo yobuchwephesha edlulileyo, sifumanise ukuba iziphene zokuwelda zihlala zenzeka ngenxa yokusetyenziswa ngokungafanelekanga kwemilomo.Ukukhetha imathiriyeli ye-nozzle efanelekileyo, ubungakanani kunye nohlobo lunokunceda ukunciphisa ixesha lokuphumla, iindleko ezisezantsi kunye nokuphucula umgangatho we-weld kunye nemveliso.
Indima yombhobho kukukhokela irhasi ekhuselayo kwichibi elinyibilikisiweyo kunye nokukhusela ichibi elinyibilikisiweyo ekungcoliseni.Ukukhetha umlomo wombhobho kunokuqinisekisa ukuba irhasi enesantya esifanelekileyo sokuqukuqela ingena kwidama elityhidiweyo elityhidiweyo.Ukuba i-nozzle efanelekileyo ayikhethwanga, i-weldment ingaba nenani leengxaki ezibandakanya i-spatter egqithisileyo kunye ne-porosity, enokuthi ekugqibeleni iholele kwixesha lokuphumla ngenxa yokusebenza kwakhona.Ngoko indlela yokukhetha umbhobho ochanekileyo ibaluleke kakhulu.Oku kulandelayo kwazisa imilomo emininzi eqhelekileyo kunye nezinto eziluncedo kunye nezingeloncedo.
umlomo othe ngqo
#Imibhobho ethe tye
Imilomo ethe tye lolona didi lombhobho luxhaphakileyo.Inzuzo kukuba isetyenziswe ngokubanzi kwaye ingasetyenziselwa kwiimeko ezahlukeneyo ze-welding, kwaye umphumo wokukhusela igesi ungcono;into engalunganga kukuba ngenxa yesiphelo esingqindilili somlomo wombhobho, ayikwazi ukungena nzulu xa i-groove imxinwa, kwaye ubude be-stick-out ubude bocingo lwe-welding luya kubangela ukuba i-arc ingazinzi kwaye ichaphazele igesi.Kwangaxeshanye, isiphelo sangaphambili sivala umgca wokubona siya kuchaphazela ukujongwa kwechibi elityhidiweyo kunye ne-arc ngexesha le-welding.
#ConeNozzle
Imilomo ye-Conical isetyenziswa ngokubanzi kwi-welding emxinwa ye-gap groove.Isiphelo sangaphambili si-conical.Inzuzo yayo kukuba isiphelo sangaphambili sincinci, sinokungena ngokunzulu kwi-groove emxinwa, kwaye kulungele ukujonga imilo ye-pool etyhidiweyo kunye ne-arc;into engalunganga kukuba i-diameter yangaphandle incinci, eya kuchaphazela ukuhamba kwegesi.Ukukhusela umgangatho, imingxuma yomoya inokuveliswa ngexesha le-welding, kwaye i-spatter ngexesha le-welding inokuthi ithintele i-nozzle, kwaye i-frequency yokutshintshwa iya kunyuka ngexesha le-welding yexesha elide, eliya kwandisa iindleko.
Ukusuka kwi-nozzle ukuya kwingcebiso yoqhagamshelwano
Ubudlelwane phakathi kwe-nozzle kunye ne-tip yoqhagamshelwano inempembelelo ebalulekileyo kumgangatho we-weld.Incam yoqhagamshelwano ingaba ngaphantsi komlomo okanye ibe phezulu kunombhobho.Incam yoqhagamshelwano esezantsi kunombhobho inokubonelela ngomgangatho ongcono wokukhusela irhasi, kodwa kwangaxeshanye iyakwenza mfutshane ubude bentonga yocingo lokuwelda, nto leyo eyenza kube nzima ukuba itotshi yokuwelda ingene kumjelo.Ngokwahlukileyo, isiluleko soqhagamshelwano esiphakamileyo kunombhobho singcono ukufikelela kwindawo ethintelweyo okanye i-bevel, kodwa umgangatho wokukhusela igesi uya kuba mbi.
Ke ngoko, umqhubi we-welding kufuneka akhethe i-nozzle efanelekileyo ngakumbi emva kokulinganisa iingenelo kunye nokungonakali.
