Kwishishini le-welding, zininziiintlobo ze-welding. I-arc welding kunye ne-spot welding zezona ndlela ziqhelekileyo. Zihlala zisetyenziswa kwiinkalo ezahlukeneyo kwaye zidlala indima ebalulekileyo kumashishini ahlukeneyo. Njengomntu oqalayo, kunokuba nzima ukuqonda umahluko. Ukuba ufuna ukufunda malunga nomahluko phakathi kwe-arc welding kunye ne-spot welding, inqaku elilandelayo liza kuzichaza ngokweenkcukacha.

Yintoni i-Arc Welding?

Ukuwelda kweArcyinkqubo esebenzisa ubushushu obuveliswa yi-arc yombane ukunyibilika kunye nokudibanisa isinyithi kunye. Umthombo wamandla we-arc welding unokubonelela nokuba kungoku ngokuthe ngqo (DC) okanye i-alternating current (AC). Ngokuxhomekeke kwiimfuno ze-welding, i-arc welding inokusebenzisa i-electrodes esetyenziswayo okanye engasetyenziswanga. Yaphuhliswa ngasekupheleni kwenkulungwane ye-19, i-arc welding idlale indima ebalulekileyo ekwakhiweni kweenqanawa kwaye ikwasetyenziswa ngokubanzi kumashishini eemoto kunye namashishini anzima.

Yintoni iSpot Welding?

Spot welding luhlobo lweukumelana weldingesebenzisa umsinga wombane ukuvelisa ubushushu kunye nokusebenzisa uxinzelelo, okubangela ukuba iindawo zoqhagamshelwano phakathi kwezinto zokusebenza zenze i-weld nugget okanye urhulumente weplastiki kwaye udibanise kunye. Yindlela yendabuko ye-welding eyona nto isebenzisa i-electrode yobhedu ukuqhuba umbane. Umbane wombane udlula kwiindawo zokusebenza, uzinyibilikise kwiindawo zoqhagamshelwano, kwaye xa i-current iyeka, uxinzelelo luqhubeka lubamba iindawo zokudibanisa kunye, zenze umdibaniselwano.

Umahluko phakathi kwe-Arc Welding kunye ne-Spot Welding

Umgaqo weWelding

I-arc welding kunye ne-spot welding isebenza kwimigaqo eyahlukeneyo. I-arc welding isebenzisa i-electrode kunye ne-workpiece ukwenza i-arc yombane, ukuvelisa ubushushu. Ubushushu obuphezulu bunyibilikisa i-electrode ibe lulwelo oluzalisa ikhonkco lesinyithi kwaye liphole ukwenza i-weld, edibanisa iindawo ezimbini zetsimbi. Olu luhlobo lwe welding engamanzi.

I-spot welding, kwelinye icala, ibandakanya ukupakisha izixhobo zokusebenza ezimbini kunye nokufaka uxinzelelo ngee-electrode ezimbini. Umbane wombane utshisa iindawo zoqhagamshelwano phakathi kwee-electrodes kunye neendawo zokusebenza, ezibangela ukuba zinyibilike. Ekupholiseni, amalungu adityaniswa kunye, nto leyo eyenza ibe ludibaniso oluqinileyo.

Imfuno yeMathiriyeli yokuSigcwalisa

Kwinkqubo ye-welding, i-arc welding ingasebenzisa i-filler metal okanye cha. Xa udityaniswa izixhobo zokusebenza ezimbini kunye, imathiriyeli yokuzalisa isenokungafuneki. I-spot welding ayifuni izinto zokuzalisa; itshisa ngokuthe ngqo i-workpieces kwimo yeplastiki ukuze idibanise nabo.

Umda wosetyenziso

I-Spot welding kunye ne-arc welding inezicelo ezahlukeneyo. I-arc welding ilungele ukuwelda iimilo ezintsonkothileyo kunye nezixhobo zokusebenza ezinkulu zetsimbi, iyenza ilungele ukulungiswa nokugcina iindawo ezinkulu kunye nezicelo zeshishini elinzima. I-Spot welding isetyenziswa ngokubanzi kwiindawo ezincinci malunga ne-3 millimeters ubukhulu kwaye ingcono kwi-high-volume welding. Isetyenziswa ngokuqhelekileyo kwimizi-mveliso yeemoto kunye nezixhobo zasekhaya.

Ixesha le-Welding

I-arc welding metal ithatha ixesha elide kwaye ayiyiyo inkqubo yexesha elinye. I-Spot welding ikhawuleza kakhulu kwaye inokugqiba imveliso ngomzuzu okanye imizuzwana embalwa.

Iindleko zeWelding

I-arc welding inexabiso eliphantsi ngokwentelekiso lokuwelda, kodwa ngenxa yobunzima bayo bobugcisa, iindleko zabasebenzi abachwephesha abanezakhono ziphezulu. I-Spot welding inexabiso eliphezulu ngokubanzi, kunye nenyeumatshini wokuwelda indawokuxabisa kangangoko oomatshini bokuwelda arc eziliqela. Nangona kunjalo, iindleko zabasebenzi kubaqhubi ziphantsi, ezinokugcina iindleko kwixesha elide.

Imfuneko yoxinzelelo lwangaphandle

Kwiimfuno zoxinzelelo lwangaphandle, i-arc welding ngokubanzi ayifuni uxinzelelo lwangaphandle. I-arc eveliswa ngumthombo wamandla inyibilika i-workpiece kunye nezinto zokuzalisa. I-Spot welding, nangona kunjalo, ifuna uxinzelelo lomoya ukucinezela i-workpieces ezimbini kunye, kwaye emva koko ubushushu buveliswa ngoku.

Ukhuseleko lokusebenza

Ukuwelda kweArc kulucelomngeni ngokobuchwephesha kwaye kufuna abachwephesha abanezakhono. Ukuba ufuna ukusebenzisa i-arc welding, kufuneka ufumane uqeqesho lobuchwephesha. I-Spot welding ilula kwaye ikhuselekile, ifuna isakhono esincinci. Abaqhubi bafuna kuphela uqeqesho olusisiseko ukuze baqalise.

Isiphelo:

Oku kungasentla ngowona mahluko uphambili phakathi kwe-arc welding kunye ne-spot welding. Xa ukhetha indlela ye-welding, kufuneka uqwalasele la manqaku. Ukuba ukhetha ukuwelda indawo okanye i-arc welding ikakhulu ixhomekeke kwimveliso ekufuneka uyiweld, imathiriyeli yayo, kunye neempawu. Umzekelo, ukuba ufuna ukuwelda umbhobho omkhulu wentsimbi, kungcono ukhethe i-arc welding kuba i-spot welding ifanele iindawo ezincinci kuphela. Ngoko ke ngaphambi kokukhetha indlela ye-welding, qiniseka ukuba uhlalutya imeko nganye kwiimbono ezininzi.
