I-Fusion Welding: Awona Mandla aPhambili kwi-Industrial Welding

I-Fusion welding lolona didi lwe-welding lusetyenziswa kakhulu. Ngeengenelo zokukwazi ukujoyina iipleyiti ezishinyeneyo kunye nokuba namandla aphezulu e-weld, iye yaba yitekhnoloji engundoqo kwimimandla efana nezakhiwo zentsimbi, iinqanawa zoxinzelelo, kunye nokwakhiwa kweenqanawa. Iquka iindlela ezahlukeneyo ezifana ne-shielded metal arc welding (SMAW), i-gas metal arc welding (GMAW), kunye ne-laser welding, phakathi kwazo ezimbini zokuqala "ziintlobo ezisetyenziswa ngokuqhelekileyo" kwimveliso kunye nokugcinwa kwemizi-mveliso.

(I) I-Shielded Metal Arc Welding (SMAW): I-Flexible kunye neLungelo "All-Rounder"

I-shielded metal arc welding (SMAW) yeyona ndlela isisiseko kunye ne-flexible welding method. Inyibilikisa iintsimbi ngobushushu be-arc phakathi kwe-electrode kunye ne-workpiece. Ngezixhobo ezilula kunye nemigangatho ephantsi yokusebenza, ilungele ngokukodwa ukugcinwa kwendawo, i-single-piece / i-batch-batch production, kunye ne-welding yezakhiwo ezinzima.

1. Umgaqo-siseko ongundoqo kunye noKuqulunqwa kweZixhobo

Umgaqo: Ingubo engaphambili ekupheleni kwe-electrode iyatshisa ukwenza igesi ekhuselayo, ihlukanisa umoya. Ubushushu be-arc bunyibilikisa i-electrode core kunye ne-workpiece ukwenza ichibi elityhidiweyo. Emva kokupholisa, intsalela yeefom zokugubungela i-slag ukukhusela isinyithi se-weld.

Izixhobo: Umatshini we-AC okanye i-DC arc welding, umnikazi we-electrode welding, i-electrode ye-welding (ekhethiweyo ngokwesiseko sesinyithi; umzekelo, i-electrodes ye-E4303 isetyenziswa ngokuqhelekileyo kwintsimbi ephantsi kwekhabhoni), kunye nezixhobo zokukhusela (i-helmet ye-welding, iiglavu ezifakwe kwi-insulated, i-welding impahla).

2. Amanqaku okuSebenza aPhambili

Ukulungiswa kwangaphambili kwe-Welding: I-electrodes kufuneka yomiswe ngokweemfuno (150-200 ° C kwi-electrodes acidic, i-350-400 ° C kwii-electrodes ezisisiseko). Susa i-oyile, i-rust, kunye ne-oxide scale kwindawo yokusebenza ukuze ugweme i-porosity; lungisa langoku ngokobukhulu bepleyiti, ngokulandela umgaqo othi "10-15A mm nganye yobukhulu bepleyiti" (umzekelo, i-60-90A ye-6mm yentsimbi yentsimbi).

Inkqubo ye-Welding: Ukutshisa i-arc usebenzisa "indlela yokukrazula" (efana nokubetha umdlalo) okanye "indlela yokuchukumisa" (impembelelo ethe ngqo ye-electrode kwi-workpiece). Lawula ubude be-arc kwi-10-15mm (malunga ne-0.8-1.2 amaxesha obubanzi be-electrode); gcina i-angle ye-60-80 ° phakathi kwe-electrode kunye ne-workpiece, kwaye uhambe ngesantya esifanayo kunye nolwalathiso lwe-welding. Lawula ubungakanani bechibi elinyibilikisiweyo ukuya kumaxesha angama-1.5-2 ubukhulu be-electrode ukunqanda ukuqiniswa kwe-weld okubangelwa yichibi elikhulu elityhidiweyo ngokugqithisileyo okanye ukungabikho kokudibanisa ngenxa yechibi elincinane elityhidiweyo.

Unyango lwe-Post-Welding: Emva kokupholisa, sebenzisa isando se-slag ukucoca i-slag. Jonga i-weld surface ukuze ubone iziphene ezifana ne-porosity, undercut, kunye nokufakwa kwe-slag. Ukuqhuba uvavanyo olungonakalisi ukuba kukho imfuneko.

3. Izicelo eziqhelekileyo kunye neMida

Iimeko zeSicelo: Izakhiwo zetsimbi zokwakha, ukugcinwa kwemibhobho, i-welding ye-mechanical part, ukwakhiwa kwebhulorho, njl., ilungele iimeko zangaphandle okanye ezo zingenawo umbane osisigxina.

Unyino: Ukusebenza kwe-welding ephantsi (ukusebenza kwe-manual), umgangatho we-weld uchaphazeleka kakhulu kwizakhono zomqhubi, kwaye awufanelekanga kwizinto ezilula ezixutywe nge-oxidized ezifana ne-aluminium alloys kunye neentsimbi ezingenasici.
