Umgaqo weWelding weShielded Metal Arc Welding (SMAW)

I-SMAW, eyaziwa ngokuba yi-electrode arc welding, yindlela yokudibanisa i-welding apho i-arc iqhutywe yi-electrode kunye neengxenye ze-welding ziyancibilika ngokushisa kwe-arc.Yeyona ndlela isetyenziswa kakhulu kwaye ixhaphakileyo yewelding okwangoku.

I-Arc yinto yokuqhuba umoya.I-arc ye-welding yinto enamandla kwaye eqhubekayo yokukhupha eyenziwa kwi-gas medium phakathi kwe-electrode kunye ne-workpiece.Ngethuba lenkqubo ye-welding, i-electrode kunye ne-weldment idibene ngokulandelelana kwii-electrodes ezimbini zomthombo wamandla we-welding.Xa i-welding core ye-electrode idibanisa ubuso be-weldment, isiphaluka sivuliwe, kwaye i-current short-circuit current iveliswa ngexesha elifanayo.Ekubeni kukho ukuchasana okuthile kuqhagamshelwano, ngokutsho kwe-Q = I2Rt, inani elikhulu lobushushu liya kuveliswa apho, kwaye ukushisa kuya kufudumala ngokukhawuleza kwaye kunyibilike umnxibelelwano.Xa i-electrode iphakanyiswe ngu-2 ~ 4mm, i-gas medium phakathi kwe-electrode kunye ne-weldment i-ionized, ivelisa i-electrons conductive kunye ne-ion positive.Ngaphantsi kwesenzo sommandla wombane, ii-electron zihamba kwi-anode, kwaye i-ion ephilileyo ihambela kwi-cathode.Ziyangqubana kwaye ziphinde zihlangane ngokuqhubekayo, ziguqula amandla e-kinetic kumandla obushushu, ngaloo ndlela zivelisa ukukhanya okuqinileyo kunye nobushushu obuphezulu, kwaye zenze i-arc phakathi kokuphela kwe-electrode kunye ne-weldment.

I-arc inyibilikisa ukuphela kwe-electrode kunye ne-weldment ehambelanayo ngexesha elinye.Intsimbi edityanisiweyo iyanyibilika yenze idama elinyibilikisiweyo, kwaye intsimbi ye-electrode iyanyibilika yenze ithontsi.Amathontsi atyhidiweyo angena kwidama elinyibilikisiweyo phantsi kwesenzo somxhuzulane kunye namandla okuvuthela kwe-arc, adibanise nesinyithi se-weld, kwaye enze i-weld emva kokuqina.Ngethuba lenkqubo ye-welding, i-coating iyancibilika ukuze yenze i-slag kunye nexabiso elikhulu legesi lenziwe, elikhuselayo kunye ne-metallurgically liphatha isinyithi se-pool etyhidiweyo.

I-arc welding iqulethwe ngamacandelo amathathu: indawo ye-cathode, indawo ye-anode kunye nommandla wekholomu ye-arc.Indawo ye-cathode ikhupha ii-electron, kwaye ubushushu buphantsi, malunga ne-2400K;indawo ye-anode yamkela ii-electron, kwaye ubushushu buphezulu, malunga ne-2600K;ubushushu obuphakathi kwendawo yekholomu ye-arc yeyona iphezulu, malunga ne-6000 ~ 8000K.

Xa usebenzisa umthombo wamandla we-arc welding ye-arc (efana ne-arc welding rectifier) ​​ye-welding, kukho iindlela ezimbini zokudibanisa: uxhulumaniso oluhle kunye noqhagamshelo olubuyela umva.Uxhulumaniso oluhle yindlela yokudibanisa apho i-electrode ixhunywe kwi-electrode engafanelekanga kwaye i-workpiece ixhunyiwe kwi-electrode efanelekileyo.Ekubeni i-electrode eyamkelekileyo yamkela ii-electron kwaye ivelisa ubushushu obuninzi, i-weldment ingena lula, ngoko le ndlela yokudibanisa isoloko isetyenziselwa ukuwelda ii-workpieces ezityebileyo.Uxhulumaniso lokubuyela umva yindlela yokudibanisa apho i-electrode ixhunywe kwi-electrode efanelekileyo kwaye i-workpiece ixhunyiwe kwi-electrode engalunganga.Ekubeni ubushushu obuveliswa zii-electron ezikhutshwa yi-electrode engeyiyo buncinane, i-weldment ayikho lula ukuyitshisa, ngoko le ndlela yokudibanisa isoloko isetyenziselwa ukuwelda ii-workpieces ezibhityileyo.

Ubushushu obuveliswa yi-welding arc bulingana nemveliso ye-arc voltage kunye ne-welding current (oko kukuthi, Q = IUt).Ngokuqhelekileyo, i-voltage phakathi kwe-weldment kunye ne-electrode xa i-arc itshiswa ngokuzinzileyo ibizwa ngokuba yi-voltage ye-arc, kwaye i-voltage ye-arc idla ngokuba kuluhlu lwe-20 ~ 35V.Ngenxa yokuba i-voltage ye-arc itshintsha kancinci, ubushushu be-arc bulungiswa ikakhulu ngokuhlengahlengisa i-welding yangoku kwimveliso.
