Semi-oluzenzekelayo iwelding uzinzo: ncomo, iifoto, iinkcukacha

Kubomi zonke umnini wesithuthi, ukuba imoto, kungekudala kuza ixesha xa iimfuno ukulungiswa komzimba. Kukho iindlela ezimbini kule meko: adibane workshop okanye ukuthenga i welding semi-oluzenzekelayo lomsebenzi umzimba kunye isiziba zabo ihashe lakhe yentsimbi.

Kweli nqaku siza kuzama ukunceda ukusebenzisa indlela yesibini, oko kukuthi, uya kuthetha ntoni ezi zixhobo, chaza intsingiselo izalathi zazo eziphambili. Ukongeza, sinikela amanye amacebiso indlela yokwenza ukhetho lasekunene iwelding semi-oluzenzekelayo lomsebenzi umzimba, kuba namhlanje imarike inika ezininzi izixhobo ezahlukeneyo.

Emele i aggregate ukuba

Segesi okuzenzelekayo - isixhobo esetyenziswa ukuwelda ucingo metal lwegesi egalelwe. Umgaqo msebenzi kukuba le kopi kufuneka siyalele kuphela zisiza endaweni oyifunayo, kunye nezinye yonke imisebenzi (amandla, ucingo feed isiqalo) isixhobo iya kwenziwa.

welding semi-oluzenzekelayo amaninzi kusetyenziswa ukudibanisa izinto zibhityile - iindawo, iphepha metal, njalo-njalo. Kungenxa yoko le nto yeyona ndlela ilungileyo ukwenza umsebenzi omzimba zokulungiswa oomatshini okanye welding izakhiwo ezahlukeneyo intsimbi ezenziwe izinto zesinyithi.

Semi-oluzenzekelayo welding kunokwenzeka kuphela phantsi kwale miqathango:

• I-medium esebenzayo (MAG olufinyeziweyo) igesi. Le carbon esetyenziswa njenge igesi olukhuselayo.
• Le egalelwe (MIG olufinyeziweyo) igesi. umxube zazisebenzisa igesi okanye argon.

Abaninzi semi-oluzenzekelayo inkxaso iwelding imo welding nokuba ngaphandle uvikele igesi, usebenzisa i "obhobhozayo" ye kwicingo (oku kuya kucaciswa kamva).

Nge MIG welding okanye MAG iindlela ye arc sombane ukubonakala phakathi izinto welding yocingo. Ukondla wegesi yokuzikhusela evela itotshi iwelding okuzenzelekayo kwaye uthintele weld evela sesichengeni ioksijini, ekubeni kukho oxidizer enamandla kakhulu kwaye iyakwazi imoshe kakhulu isiphumo. Le umthungo akayi ingazinzi kuphela, kodwa kunokuba ngokukhawuleza Rust.

Semi-oluzenzekelayo iwelding uzinzo: ifoto kunye iintlobo eziphambili

oomatshini Welding zahlulwe iiklasi 3 - umsebenzi, semi-zobungcali kunye nomthengi. umahluko yabo kwi ngoku eliphezulu, ekhutshwe yi umthombo wamandla, kwakunye kwipesenteji ixesha yokusebenza (olufinyeziweyo ku MF). Ukuba koomatshini zobungcali iwelding semi-oluzenzekelayo bayakwazi lokuhambisa iwelding yangoku ukuya 300 A okanye ngaphezulu, ebuntlangorha - up to amperes 300, kunye nendlu - ukuya ku-200 Esi parameter, njengepesenti yabo ixesha yokusebenza iza kuqwalaselwa kamva ephepheni.

Kwakhona semi-oluzenzekelayo iwelding uzinzo unokuba umthombo wamandla, wayebhekisela kwenye kweentlobo ezintathu. Bangakwazi:

• inverter;
• transformer;
• rectifiers.

inverter semi-automatic

Yeendleko zezi yunithi iphezulu kodwa ubunzima kunye nobukhulu incinane kakhulu, nto leyo ebalulekileyo xa besebenza. Kananjalo inverter buchwepheshe inikezela ngeempawu ezifana arc ucinezelo egudileyo, antiprilipanie ucingo kunye namathuba modulating i welding yangoku. Le welding uzinzo umsebenzisi ingxelo semi-ezenzekelayo HIV kakhulu.

lokubolekwa transformer

Zisetyenziswa kwiindawo apho akuyomfuneko ukuthutha ifowuni kwaye akukho sithuba esaneleyo ukuze ukufakwa kwayo.

Design kunye neempawu semi-oluzenzekelayo welding

qhagamshelana ifowuni ngokokwakheka inezi zinto:

• umthombo wamandla (a sombane, rectifier okanye inverter);
• inkqubo yolawulo ekhoyo kunye feed wire;
• kwicingo feeder;
• Segesi sleeve lokubonelela igesi kunye wire;
• sokukhuphela.

Ukongeza, umatshini welding kufakwa ubunzima intambo. Ezinye lokubolekwa sanikwa umsebenzi welding kunye iqhekeza elula exhotyiswe electrode ezizodwa kunye cable-umnini electrode.

Yaye segesi Ukongezelela kufuneka uthenge gearbox kunye nesilinda ukuba uvikele igesi. Ezi izincedisi idla iwelding okuzenzelekayo ayikagqitywa, yaye kufuneka zingathengwa ngokwahlukeneyo.

Kukho ezi ndidi zilandelayo wire feeder:

• ukutyhala, xa actuator elahliweyo kwi izixhobo pushes wire sleeve iwelding;
• eyendawo mechanism xa umqheba actuator ukho kule sokukhuphela.
• uhlobo push-atyhale, agibiseleke okanye ezidityanisiweyo izixhobo abathengi isetyenziswa enqabile.

wire welding

Ubukhulu be wire iwelding inokuba 0.6-2.0 mm. Oku inxeba azifake nesondo, nto leyo ifakwe ngaphakathi kopi. Oku ocande indlela feed wire of ukuwelda emkhonweni kunye sokukhuphela.

Ukwahlula wire;

• steel;
• stainless;
• aluminium.

uhlobo nganye ikhemikali Ukwakhiwa ezahlukeneyo kwaye usetyenziswa ukuwelda phantsi kweemeko ezahlukeneyo.

Xa ukujoyina ayoni metal weld ifunyenwe umgangatho ngcono xa usebenzisa steel wire kunye ukutyabeka lobhedu, apho qhagamshelana engcono ombane kuyaqinisekiswa. Ngexesha ukusebenza, lo ombane kunye kwama ngoku ziyancipha. Amagcisa Guest ukuqinisekisa oku.

Xa aluminium upheka kufuneka asebenzise ezifanelekileyo ucingo argon nomxube okanye argon negesi olukhuselayo.

Enye locingo lomgubo (Flux), umsebenzi wakhe kunokwenzeka ngaphandle uvikele igesi. Kubonakala ngathi ityhubhu obhityileyo, ngaphakathi apho ibekwe wampompoza. Akhiwa igesi yokutsha, elisikhusela igcwala indawo welding. Umthungo, apho iveliswa ngokusebenzisa ucingo nobhobhozayo, hayi umgangatho. I-plus kuphela - na ukungabikho webhotile gas.

The main iparameters

• Umjikelo Duty (PT olufinyeziweyo) - i parameter kubonisa ngokwepesenti kumatshini iwelding ixesha yokusebenza imizuzu eli-10. Ngoko ke, umzekelo, i-60% umjikelo umsebenzi kwindawo yangoku 300 A kukuba ukuze ngoku elinikiweyo ukucima umatshini bangasebenza imizuzu 6, emva koko icinyiwe yi shushu ngokugqithisileyo kwaye kuya kufuneka ixesha elithile emsebenzini okupholisa. Ngoko ke, lo liphakamile ixabiso, umgangatho ophezulu uya kuba welding semi-oluzenzekelayo lomsebenzi umzimba.
• Power ukusetyenziswa - lixabiso esibonakalisa ukusetyenziswa amandla kangakanani ukusuka kumatshini iwelding grid yombane. Ngokusekelwe kule parameter, uyakwazi ukubona ukuma ukuba ezidityanisiweyo iyunithi network egadini okanye igaraji.

Indlela ukukhetha i welding semi-oluzenzekelayo?

Ukuze kube lula ukwenza isigqibo uhlobo iwelding semi-automatic ngcono, kuqala kufuneka ukwazi imisebenzi ekufuneka yenziwe kule fowuni. Ukuba uceba kwi ukupheka ezingcakacileyo kakhulu sheet metal, kucetyiswa ukuba uthenge iyunithi kakhulu zesiqhelo. Ukupheka, ahlawule izakhiwo metal shinyi ngcono ingqalelo ukuwelda oomatshini kunye umsebenzi "2 1". Bona bayakwazi ukupheka intonga electrode njengesiqhelo.

Xa uthenga sinikele ingqalelo yabo ukusetyenziswa amandla yemodeli ukubona ukuba lo uya kumxhasa umsebenzisi grid. Kwakhona, isigqibo oceba kangaphi ukuze kunikezelwe okuzenzelekayo welding. Ukuba uhambo rhoqo ukuba kuhlelwe, kunokwenzeka ukuba bathenge amatikiti achazayo wesiqingatha-oluzenzekelayo iwelding sombane uzinzo. Cela umthengisi malunga phambi iinxalenye imodeli ezikhethiweyo ziphele.
