Inkqubo ye Ukulungiselela umsebenzi

Indlela kuphekwe lenkcenkce? Indawo ukuba welding kufuneka zibekwe phantsi intsimbi, kuba njani na kowomileyo. Ezingavumelekanga enze umsebenzi welding kwimozulu emanzi, imvula nomoya kumaqondo obushushu aphantsi. Ngaba kuvunyelwa ukuba zentsimbi manzi kunye electrode.

Indlela weld metal yi yombane?

Welding lwenziwa kwindawo ombane rhoqo okanye nokuxuba. abatyhidi transformer welding ukunika AC ombane.

Xa segesi yamanje ngqo iindlela ezimbini loqhakamshelwano umatshini welding. Xa uqhagamshela kuso ubunzima kunye no thabatha ukuya electrode (oku kubizwa ngokuba wokwephuka phambili) mkhulu wentsimbi eshushu, ummandla linyibilike idaliwe enzulu emxinwa. Loo utshintsho esetyenziswa kwi welding otyhidiweyo eshinyeneyo kwaye ikhokelela ukusetyenziswa eyongayo electrode. Xa wajika malungana (wokwephuka umva) ngakumbi shushu ngamandla kwaye walidla zone yokunyibilika kungekudala electrode wafumana ububanzi nzulu. Ngoko ke, ezichaseneyo umva isetyenziswa kuphela xa ukuwelda zizixwexwe ngentsimbi.

iimpawu ezikhethekileyo inverters

Indlela apheke metal inverter? oomatshini welding Inverter ukuguqula AC umbane yorhwebo ombane ibe kulandelelwano ubume ezineqondo ephakamileyo uze kwenza ombane yangoku DC. Ngenxa wesekethe elektroniki leyo liyazi ukuguqulwa data, le inverter inefuthe encinane unikezelo mbane ngexesha lokusebenza, kukho utshintsho omhle ombane imveliso, ebonakala ngu ubunzima encinane kunye nobukhulu. Umgangatho onesiphumo weld inverter engabumbeki kwezinye izixhobo efanayo. Ngoko ke, inverters welding owalwamkelayo kwiminyaka yakutshanje, xa ixabiso izixhobo ezinjalo ziye zasinciphisa, ukuba yande kakhulu. Abaxhamla kule divaysi lula ekhoyo ukusetyenziswa kwayo kumsebenzi wokutshisa iintsimbi.

Indlela ukukhetha inverter

An parameter ebalulekileyo ixesha wolayisho inverter (MF) umthombo wamandla. Eli xabiso, leyo olwahlula ukusebenza kakuhle inverter, ibonisa ukuzalana ixesha iwelding besonqena ixesha. izixhobo zasekhaya azisebenzi ngokuqhubekayo. Kufuneka ukuba uphole ngamathuba athile. Ngenxa yoko, 30% yexabiso PV le inverter kuthetha ukuba emva kwemizuzu 3 kufuneka weld salinda yemizuzu-7 ukuze yemvelaphi ukuze uphole. Xa uzama ukuba uqhubeke ngaphandle kokuphazanyiswa iyunithi ezikwaziyo ukuvutha. Okanye ukusebenza ukhuselo, yaye oko kuya vala. Ngoko ke, lo inverter kufuneka zikhethwe kunye MF-60% kunye current ubuninzi ubuncinane 140 - 160 A.

Ukuqalisa kunye inverter

Ukuze ufumane amava indlela ukupheka kakuhle inverter metal, kucetyiswa ukuba basebenze metal ubuncinane 2-3 mm ubukhulu-3 mm usetyenziswa electrode. Electrode ngcono ukuthenga ezintsha. Old, sekukudala, abolekwe kwabanye, kusenokwenzeka ukuba babe kunye emanzi ukuba angakulungeli ukusetyenziswa.

Indlela kuphekwe lenkcenkce? Ukuba oku ngamava wenu wokuqala, kuqala zama ukwenza nokuhlangana kwayo, phezu komhlaba enye metal ngaphandle ukuwelda kunye kwenye indawo.

Cinga ulandelelwano lomsebenzi.

Okokuqala, kuyimfuneko ukudibanisa umnini ukuya electrode, kwaye intambo emhlabeni ukuya workpiece welding ngokusebenzisa ezinjengeetheminali. Ezinye iziphelo ngcingo izakubanodibaniso ukuya kwimveliso inverter kwi wokwephuka eqhelekileyo.

Okwesibini, kufuneka ukuba uvule iyunithi yaye ubeke yayo imveliso ngokungqinelana kunye nezincomo ngokuxhomekeke ububanzi izinto eziza nge welding kwaye electrode yisayizi ekhethiweyo.

metal iwelding ndlela ubonelela ukuba ngokushushubeza intsimbi kwiqondo lobushushu efunekayo ukuze ufumane weld esemgangathweni kuyimfuneko ukuba ubukhulu efanelekileyo izinto electrode. I ziyatyeba wokugqibela, kokukhona umaleko wesinyithi bunokuzifudumeza phezulu kwaye ngoku ngakumbi kufuneka abekwe kwisekethe inverter for arcing. Ngelo xesha, ukuba phezulu ngoku, i ngokukhawuleza intsimbi zaphela ne electrode kuyaphela ngokukhawuleza. Kuba umaleko zesinyithi ezicekethekileyo kunye mingxuma eliphezulu zangoku kunye ezinkulu badla kwakhiwa electrode, aqhumisele-nge eziphathekayo. Xa current ephantsi kakhulu lungenzeki okanye arc wombane, nokuba, xa kusenzeka, kuvela ingenamthungo enesiphako, benjenjalo ukumemeza neprogar.

Into yesithathu kufuneka sinikele ingqalelo - oku ukuyilwa i arc yombane. Kuba oku kufuneka ukuba bambethe kwincam electrode kwindawo, eza nge welding, njengoko umdlalo le bhokisi, ngaphandle kokususa incam electrode ukusuka metal. Kwimeko apho i arc akhiwa ndawo ebomvu kwi metal. Kodwa asiyiyo loo etyhidiweyo, kwaba ligazi ukumpompoza kwenziwa kuphela xa ukunyibilika ngumgubo esingxobeni electrode. Kufuneka linda ngexesha ubambe i ekupheleni electrode kumgama 1-4 mm ukusuka phezu intsimbi, yonke imihla yenkcenkce arc akuthethi akakhululeki ukuya ukuyilwa-kuthiwa weld pool - amathontsi etyhidiweyo, ebonakala ngu umbala orange eqaqambileyo nokungcangcazela uhuhamba yangoku.

Okwesine, kuyimfuneko ukuba bayeke ukuya umthungo ukuphunyezwa yi omnye ukuya kwemibini eemilimitha ekupheleni electrode, ukugcina kwakhona kwindawo ecacisiweyo.kumgama ukusuka metal. Kwakhona, linda ukuba ukuyilwa ngamathontsi, njalo njalo, zihamba weld eyenziwa. Xa iphathwayo, umphezulu electrode metal kudala short circuit, i arc liyalahleka, lo inverter disconnects yangoku. Ngoko kuyimfuneko ukuba uzame ukugcina umgama rhoqo phakathi incam electrode kunye umphezulu intsimbi xa weld, bephethe i electrode ngcembe oko njengoko yokutsha yayo. Kunoko, i electrode lingatshi liphele linyibilike, intsimbi kwi weld pool luqokelelane ikakhulu ongundoqo yenkcenkce electrode. Luthuli-camera electrode umphezulu, yenza wampompoza kwaye zavuleka iigesi ekuthinteleni oksijini evela emoyeni okukufutshane ukuya metal weld kunye namachibi, kwakunye ekuncedeni inkqubo yokutshata weld ezikumgangatho ophezulu.

Ngexesha lenkqubo welding Kucetyiswa ukubamba electrode kwi-engile izidanga malunga-30 ukusuka nkqo ukuya workpiece ukuze ukwenza weld pool compact nendawo weld okulungileyo ungabona. Abo ngakumbi i electrode ukuya workpiece ngexesha welding, ukuba side ngaphezulu kwelinye icala aya angcolise ubungangamsha imiphezulu zesinyithi itshiswa ukuyilwa kuqokobhe weld kwi kul efanayo. Le ndawo yokunyibilika kwaza ngentsimbi kufikelelwa kwi kwindawo aa Incopho kumphezulu electrode yesinyithi. Kodwa ke kule meko nzima zentsimbi phononongo lweNyanga inkqubo welding. Ngoko ke, le meko lisetyenziswa kuphela xa ukuwelda nakwizikhewu avalelwe.

Indlela weld inverter metal?

Ekubeni baqeqeshwa ekuqhubeni weld elula phezu angaqala mix iinxalenye yesinyithi. Le nkqubo efanayo, umahluko amanga neqiniso ukuba umba nge welding, kufuneka kuqala ukulungiswa endaweni ne kwesibambi okanye ezinye iindlela, kwaye ukususa ekupheleni electrode akukho ngqo kunye nokuhlangana kwayo, kunye neentshukumo amajikojiko kweli ziko joint xa kuqokobhe weld kwicala elinye lokuqala ke enye iindawo, ngokuthe ngcembe zihamba umthungo, ngaloo ndlela yokungena kubo.

Eyona nto ibalulekileyo - impumelelo kuvela kumava. Ngokuthenga kuyo, ungenza endaweni usebenzise iinkonzo leengcali zangaphandle (kangangethuba eninzi) ukuze ufunde ukwenza njani umsebenzi welding ngezandla zabo. luck Good ukufunda kunye nokusebenza!
