Tok i go pas
Insait long wok bilong wokim ol ain,MFDC (Medium Frequency Direct Current) spot weldaem ol bikpela samting bilong weldim, na kwaliti bilong weldim bilong ol i save mekim gutpela wok long strong na sefti bilong prodak. Tasol, sampela taim long taim bilong wok bilong weldim, yumi ken bungim hevi bilong ol 'bubble' i kamap long ol hap bilong weldim. Dispela i no bagarapim lukluk bilong 'weld' tasol em i ken bagarapim strong bilong en tu. Dispela atikol i lukluk long het tok "Bilong wanem i gat ol 'bubble' long ol 'spot weld points' bilongOl MFDC spot welda?", i painimaut ol as bilong en, na i givim ol rot bilong stretim hevi.
Skelim as bilong hevi
- Kontaminesen bilong pes:Sapos ol i no klinim gut pes bilong ain pastaim long ol i weldim, ol pipia olsem oil, pipia, na ol 'oxide' inap long lusim ges aninit long bikpela hat bilong weldim na kamapim ol 'bubble'.
- Ol samting we i save pairap:Ol samting we i save pairap long ol samting bilong weldim o long ol samting i stap klostu, olsem peint o 'lubricants', inap long kamap steam taim ol i hatim. Ol dispela ges i pas insait long 'molten pool' na kamapim ol 'bubble'.
- Ges Absopsen:Ol samting bilong ain inap long kisim ol ges olsem haidrojen o oksijen taim ol i weldim. Taim tempereja bilong ples i go antap, ol dispela ges i save lusim, na dispela i save kamapim ol 'bubble'.
- Ol 'Welding Parameters' we i no stret:Sapos yu no stretim gut ol samting olsem 'welding current', taim, na presa, dispela inap long mekim ol 'welding materials' i hat tumas o i no hat tumas, na dispela inap kamapim ol 'bubble'.
- Metal Vapor:Long taim bilong bikpela hat, ain inap long tanim i go insait long 'vapor'. Taim dispela steam i kol na kamap kondens, em inap kamapim ol 'bubble' tu.
- Ol samting bilong weldim i no wankain:Ol kemikel riaksen we i no stap gut namel long ol narapela narapela samting inap long kamapim ol 'bubble'.
- Ol hevi bilong banisim ges:Ol hevi olsem 'shielding gas' i no klin gut o 'leak' insait long ol 'gas line' inap long mekim 'gas protection' i no gutpela long taim bilong 'welding', na bihain dispela inap kamapim ol 'bubble'.
Ol rot bilong stretim hevi
- Mekim gutpela wok bilong klinim:Yu mas klinim gut pes bilong ain pastaim long yu weldim long rausim oil, pipia, na ol 'oxide', na daunim ol samting we i save kamapim ges.
- Kontrolim Envairomen:Noken weldim long ol ples we i gat ol samting we i save pairap hariap, o rausim gris na klinim ol komponen pastaim long weldim.
- Stretim ol welding paramita:Setim ol samting olsem 'welding current', taim, na presa stret bihainim ol 'welding materials' na ol samting we proses i nidim long abrusim hat tumas o hat i no inap.
- Makim ol gutpela samting bilong weldim:Mekim gut olsem ol samting bilong weldim i ken wok gut wantaim long abrusim ol kemikel riaksen we i no stap gut.
- Sekim na lukautim gut 'Shielding Gas System':Sekim gutpela bilong 'shielding gas' (mekim gut olsem em i antap long 99.7%); sekim ol ges lain oltaim sapos ol i lik na lukim olsem ol i klin; sekim sapos 'solenoid valve' we i bosim 'shielding gas' insait long 'welder' i wok gut.
- Klinim 'Nozzle' oltaim:Ol liklik pipia inap pas long 'nozzle' taim yu weldim, na dispela inap long bagarapim 'gas protection'. Olsem na, klinim 'nozzle' oltaim, ol i save tok olsem yu mas klinim olgeta 20-30 minit.
- Ol Tren Opereta:Strongim trening bilong ol opereta long kamapim gutpela save bilong ol long wok bilong weldim na ol ikwipmen, na mekim wok i kamap wankain na ol i putim ol gutpela paramita.
Long pinisim, as bilong ol 'bubble' long ol 'weld points' bilongOl MFDC spot weldai gat planti samting na i gat kain kain. Tasol, long rot bilong kamapim ol samting olsem klinim gut, bosim envairomen, stretim ol paramita, makim ol samting, lukautim 'shielding gas system', klinim ol 'nozzle' oltaim, na trening bilong ol opereta, yumi inap long daunim o abrusim ol 'bubble' fomesen, na long dispela rot yumi inap long mekim wok bilong weldim i kamap gutpela moa.
