Okokuqala, ukufudumeza kwangaphambili:
1. Kwi-workpiece enemilo enzima okanye inguqu ebukhali yecandelo kunye nobukhulu obukhulu obusebenzayo, kufuneka ifudunyezwe.
2. Indlela yokufudumeza kwangaphambili: i-preheating ye-800 ℃, i-preheating yesibini yi-500 ~ 550 ℃ kunye ne-850 ℃, izinga lokunyuka kweqondo lokushisa lokuqala kufuneka lilinganiselwe.
Isibini, ukufudumeza:
1. Kukho iinotshi kunye nemingxuma kwi-workpiece, ukuphosa kunye ne-welding parts kunye ne-processed steel stainless workpiece, ngokubanzi kungekhona kwindawo yokufudumeza ityuwa.
2. Qinisekisa ukuba i-workpiece ifudunyezwa ixesha elaneleyo.Bala ubukhulu obusebenzayo bomsebenzi kunye nobukhulu obunemiqathango (obona bukhulu buphindaphindwe ngomlinganiso wemilo yepiece workpiece) ngokubhekisa kwiTheyibhuli 5-16 kunye neTheyibhile 5-17.
Okwesithathu, ukucoca:
1. I-workpiece kunye ne-fixture kufuneka ihlanjululwe ngeoli, ityuwa eseleyo, ipeyinti kunye nezinye izinto zangaphandle ngaphambi kokunyanga ukushisa.
2. Isixhobo esisetyenzisiweyo okokuqala kwisithando somlilo kufuneka sihlanjululwe kwaye sihlanjululwe kwangaphambili ubuncinane phantsi kweqondo le-vacuum elifunwa yi-workpiece.
Isine, iziko liyalayishwa:
1. Kwinkqubo yonyango lokushisa, i-workpiece ephosakeleyo kufuneka ifudunyezwe kwindawo ekhethekileyo
2. I-workpiece kufuneka ibekwe kwindawo yokufudumala esebenzayo
