1 Zofunikira zamawotcherera
Owotcherera adzapereka chidziwitso choyambira ndi kuwunika kwa machitidwe a Boiler and Pressure Vessel Welder Examination Rules opangidwa ndi Unduna wa Zantchito ndi Ogwira ntchito ku People's Republic of China, ndikukhala ndi satifiketi yoyenerera asanayambe ntchito zowotcherera mkati mwa nthawi yovomerezeka.
Vavu ndi wa kuthamanga chotengera, luso mlingo wa kuwotcherera ndi kuwotcherera ndondomeko mwachindunji zimakhudza khalidwe mankhwala ndi kupanga chitetezo, choncho n'kofunika kwambiri zofunika okhwima kwa kuwotcherera, kuwotcherera ndi ndondomeko yapadera mu mabizinezi kupanga valavu, ndondomeko wapadera ayenera kukhala ndi njira yapadera, kuphatikizapo ogwira ntchito. , zida, kasamalidwe ka zinthu ndi kuwongolera.
2 Zofunikira zosungirako ndodo zowotcherera
(1) Samalani ndi chinyezi zachilengedwe kuteteza elekitirodi ku chinyezi, chinyezi wachibale mu mlengalenga ndi zosakwana 60%, ndi kusiya pansi ndi khoma mtunda wina (pafupifupi 30cm).
(2) kusiyanitsa elekitirodi mtundu, specifications sangakhoze kusokonezedwa.
(3) Transportation stacking ndondomeko ayenera kusamala kuti kuwononga mankhwala khungu, makamaka zosapanga dzimbiri elekitirodi, kuponyedwa chitsulo elekitirodi, etc.
Ndodo yowotcherera yomwe imagwiritsidwa ntchito popangira kuwotcherera kukonza komanso kuwotcherera kwazinthu zama valve
Onani Table 1-3-1 pamagiredi owotcherera omwe amagwiritsidwa ntchito powotcherera pokonza komanso kuwotcherera mwamapangidwe azinthu zama valve.
