Izindaba - Irobhothi le-Yooheart litshela izaziso zokushisela kwegesi evikelayo

Ukushisela okuvikelwe kwegesi kubhekisela endleleni yokushisela evikelwe yi-carbon dioxide noma i-argon, ngaphandle kokusebenzisa ucingo lokushisela. Inqubo yokushisela evikelekile ngegesi ifanele ukushiselwa kwemiklamo ehlukahlukene yesakhiwo sensimbi emikhulu njengensimbi enekhabhoni ephansi kanye nensimbi ene-alloy ephansi enamandla amakhulu. Inokukhiqiza okuphezulu kwe-welding, ukumelana nokuqhekeka okuhle, ukuwohloka okuncane kwe-welding, kanye nohla olukhulu lokuguquguquka. Ukushisela amapuleti amancane namapuleti aphakathi nendawo nawugqinsi kungenzeka.

Izindlela ezahlukahlukene zokushisela zokushisela okuvikelwe kwegesi

1. ukushisela phezulu phezulu

Isikhundla sethoshi lokushisela sibaluleke kakhulu lapho i-welding ibheka phezulu, futhi ithoshi yokushisela kufanele ibe yi-perpendicular to workpiece. Ngesikhathi sokushisela komugqa oqondile, ubuhlalu be-weld buvame ukuba yi-convex, futhi ukubukeka kwe-weld bead kubi futhi kulula ukusika.

Ngesikhathi se-welding ye-multi-layer, i-back fill bead kulula ukungakwazi ukungena kuyo, ngakho-ke ngokuvamile ayisetshenziswa. Ngakho-ke, ukushisela okubheke phezulu kuya phezulu kuvame ukushwibeka, futhi indlela yokushwiba iwukushwibeka okuncane. Njengoba ukushisa kugxilile ngalesi sikhathi, i-weld bead kulula ukugoqa, ngakho kufanele ikhuphuke ngokushesha ngaphansi kwesimo sokushwibeka okufanayo.

Uma kudingeka umlenze wokushisela omkhudlwana, indlela yokushwiba i-crescent kufanele isetshenziselwe ukuhamba ngokushesha phakathi nendawo yobuhlalu obushiselayo futhi uhlale kancane nhlangothi zombili ukuvimbela ukusika phansi. Kodwa-ke, kufanele kuqashelwe ukuthi ungasebenzisi i-crescent swing ebheke phansi.

2. mpo phansi welding

Ku-welding ebheke phansi eqondile, ukuze kugcinwe ichibi elincibilikisiwe, ithoshi lokushisela kufanele likhombe ngokudayagonali phansi echibini elincibilikisiwe futhi ligcine i-engeli ethile. I-arc kufanele ihlale iqondiswe ngaphambili kwechibi elincibilikisiwe, ngaphandle kwalokho, uma insimbi encibilikisiwe igeleza ngaphambi kwe-arc, kulula ukubangela izigaxa zokushisela nokungangeni. Insimbi yephuli iphushele phezulu.

Izimbangela ze-porosity ekushiseleni okuvikelwe kwegesi

Igesi yokuvikela embi

1. Ikhwalithi yegesi ku-cylinder yegesi ayilungile, futhi ayinakho ukuhlanzeka okungaphezu kuka-98%. Iqukethe amagesi ayingozi njenge-nitrogen, abangela ama-pores ngemva kokushisela.

2. Ipayipi legesi elisuka kusilinda segesi liya ethoshi lokushisela aliqinile, futhi umoya ungeniswa ukuze ukhiqize izimbotshana.

3. I-air turbulence ikhiqiza i-stomata

a. Umoya osendaweni engaphandle uphazamisa ukugeleza komoya okuvikelayo okuzungeze ichibi elincibilikisiwe

b. Ukugeleza kwegesi okuphansi noma i-splatter evala umlomo

c. I-engeli yethoshi yokushisela inkulu kakhulu noma ithoshi lokushisela likude kakhulu nendawo yokusebenza

d. Indandatho yomhlahlandlela we-gas shunt ceramic yomlomo wethoshi yonakele futhi ayikasuswa noma ayikashintshwa

4. Ivalvu yomoya yokulawula umshini wokushisela ivula i-lag, ivaleke kusenesikhathi, noma ayixhumani kahle ngezikhathi ezithile

Amaphutha ocingweni lokushisela nesisekelo sensimbi ngokwayo

1. Ucingo oluqinile lwe-welding lugqwalile, lunamafutha, njll.

2. Impushana yangaphakathi yocingo lwe-welding ene-flux-cored inomswakama, futhi ingaphandle igqwalile.

3. Kunezimbotshana kusisekelo sensimbi ngokwayo, noma kunokuningi ukungcoliswa kukawoyela ngaphakathi, noma ukushintsha kwekhwalithi yensimbi okubangelwa ukusetshenziswa isikhathi eside ezindaweni zamakhemikhali, njengamapayipi amakhemikhali, insimbi yokusansimbi yethuluzi lomshini kanye nezingxenye zensimbi.

4. Kukhona ukungcola noma amanzi akhiqiza amagesi ayingozi endaweni yokushisela, futhi awahlanzwa.

Imingcele ye-welding engenangqondo

Uma ukulungiselelwa kwamanje kanye ne-voltage kukukhulu kakhulu, kulula ukubola i-carbon dioxide ibe yi-carbon monoxide endaweni yokushisa ephezulu kanye ne-ionization ephezulu uma okokufaka ukushisa kukhulu, futhi izimbotshana ze-carbon monoxide zizokhiqizwa uma ukushisela kuphola ngokushesha.

Isiphakamiso sesixazululo

1. Engeza i-argon noma i-carbon dioxide exutshwe igesi ukuze uhlole ukuthi igesi ye-carbon dioxide ingcolile, futhi ubheke ukuthi ingabe igesi exubile inomphumela ongcono wokuvikela. Uma kunjalo, shintsha iyunithi yokuhlinzeka ngegesi ngekhwalithi enhle.

2. Ngaphansi kokuvikelwa kwegesi exubekile, kusekhona ama-pores okuqeda imbangela yegesi, nezinye izizathu zingabhekwa ngokubonakalayo.

3. Kungcono ukungazinaki izinkinga zensimbi eyisisekelo kanye ne-welding wire uqobo.
