Mechini ea welding ea koporo ke lisebelisoa tsa bohlokoa lits'ebetsong tse fapaneng tsa indasteri, tse tsejoang ka bokhoni ba tsona ba ho theha li-welds tse matla le tse tšepahalang likarolong tsa koporo. Bohareng ba ts'ebetso ea ho cheselletsa mochining ona ke taolo ea mocheso, e bapalang karolo ea bohlokoa ho fihlelleng litšepe tse atlehileng. Sehloohong sena, re tla hlahloba mohloli oa mocheso le potoloho ea ho tjheseletsa metjhini ea ho tjheseletsa lere la koporo.
Mohloli oa Mocheso: Motlakase oa Arc
Mohloli o ka sehloohong oa mocheso mochining oa ho tjheseletsa lere la koporo ke arc ea motlakase. Ha ts'ebetso ea welding e qala, arc ea motlakase e hlahisoa pakeng tsa li-electrode le molamu oa koporo o fella. Arc ena e hlahisa mocheso o matla, o tsepamisitsoeng sebakeng sa ho kopana pakeng tsa melamu. Mocheso o hlahisoang ke arc ea motlakase ke oa bohlokoa bakeng sa ho qhibilihisa libaka tsa molamu le ho etsa letamo le qhibilihisitsoeng.
Welding Cycle: Mehato ea Bohlokoa
Potoloho ea ho tjheseletsa metjhini e tjheseletsang melamu ya koporo e na le methati e mmalwa ya bohlokwa, e nngwe le e nngwe e kenya letsoho ho thehweng ka katleho ha lenonyeletso le matla le le ka tshepehang la weld. E latelang ke mekhahlelo ea mantlha ea potoloho ea welding:
1. Clamping le Alignment
Mokhahlelo oa pele o kenyelletsa ho koala melamu ea koporo ka mokhoa o sireletsehileng le ho etsa bonnete ba ho tsamaisana hantle. Mohato ona ke oa bohlokoa ho fihlela motsoako o otlolohileng le o tšoanang oa weld. Mochini oa ho koala mochini oa welding o boloka melamu ka mokhoa o sireletsehileng, o thibela ho sisinyeha leha e le hofe nakong ea ts'ebetso ea welding.
2. Motlakase oa Arc Initiation
Hang ha lithupa li koaletsoe 'me li lumellane, arc ea motlakase e qala. Motlakase oa motlakase o feta ka har'a li-electrode ebe o phalla ho pholletsa le lekhalo le lenyenyane pakeng tsa lipheletso tsa molamu. Hona joale sena se hlahisa mocheso o matla o hlokahalang bakeng sa ho cheselletsa. Arc e laoloa ka hloko ho thibela ho futhumala le ho etsa bonnete ba ho futhumala ho tšoanang ha libaka tsa molamu.
3. Ts'ebeliso ea Khatello ea Welding
Ka nako e ts'oanang le arc ea motlakase, khatello ea welding e sebelisoa ho tlisa melamu ea koporo haufi. Khatello e sebetsa merero e 'maloa ea bohlokoa: e boloka ho tsamaisana, e netefatsa ho kopanngoa ha mapolanka hantle, le ho thibela likheo leha e le life tsa moea tse ka senyang boleng ba weld.
4. Fusion le Pool Formation
Ha arc ea motlakase e ntse e tsoela pele, mocheso o hlahisoang o qhibilihisa bokaholimo ba molamu oa koporo. Sena se etsa hore ho thehoe letamo le qhibilihisitsoeng sebakeng sa weld joint. Ho kopanya hantle ho bohlokoa ho theha weld e matla le e tšepahalang.
5. Welding Hold Khatello
Ka mor'a hore motlakase oa tjheseletso o tingoe, ho bolokoa khatello ea welding ho lumella letamo le entsoeng ka ho qhibilihisoa hore le tiee le hore chesello e pholile. Mokhahlelo ona o etsa bonnete ba hore lenonyeletso le tiea ka ho lekana le hore botšepehi ba weld boa bolokoa.
6. Ho pholisa le ho Tiisa
Hang ha sethala sa khatello se phethiloe, lenonyeletso le cheselitsoeng le ba le pholileng le ho tiisa. Mokhoa ona oa ho pholisa o etsa bonnete ba hore motsoako oa weld o finyella matla a oona a feletseng le hore lipheletso tsa molamu oa koporo li kopane ka katleho.
7. Tlosa Khatello
Qetellong, khatello ea tokollo e sebelisoa ho lokolla lenonyeletso le cheselitsoeng mochining oa clamping. Mokhahlelo ona o lokela ho laoloa ka hloko ho thibela ho khopama leha e le hofe kapa tšenyo ea weld e sa tsoa thehoa.
Qetellong, mohloli oa mocheso mochining oa ho tjheseletsa oa copper rod butt ke arc ea motlakase, e hlahisang mocheso o matla o hlokahalang bakeng sa ho cheselletsa. Potoloho ea welding e na le methati ea bohlokoa, ho kenyelletsa ho koala le ho tsamaisana, ho qalisoa ha arc ea motlakase, ts'ebeliso ea khatello ea welding, fusion le sebopeho sa letamo, khatello ea ho ts'oara, ho pholisa le ho tiisa, le khatello ea ho lokolla. Ho utloisisa le ho laola mekhahlelo ena ka katleho ho bohlokoa bakeng sa ho fihlela li-welds tse matla, tse tšepahalang le tsa boleng bo holimo lits'ebetsong tse fapaneng tsa indasteri.
