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 ifudunyezwe 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. Umsebenzi kunye nokulungiswa kufuneka kucocwe ngeoli, ityuwa eseleyo, ipeyinti kunye nezinye izinto zangaphandle ngaphambi kokuba unyango lobushushu
2. Isixhobo esisetyenziswe okokuqala kwisithando somlilo kufuneka sihlanjululwe kwaye sihlanjululwe kwangaphambili ubuncinane phantsi kweqondo le-vacuum elifunwa yi-workpiece.
Isine, iziko liyalayishwa:
1. Kwinkqubo yokunyanga ukushisa, i-workpiece ekhubazekayo kufuneka ifudunyezwe kwindawo ekhethekileyo
2. I-workpiece kufuneka ibekwe kwindawo yokufudumala esebenzayo
