Panguva yekuiswa kwepamusoro kwe304 simbi isina tsvina, kukanganisa kwakati kunogona kuitika.Zvimwe zvinowanzoitika zvinosanganisira:
1.Porosity:
Porosity inoreva kuvapo kwezvivharo zvidiki kana homwe dzegasi mune yakasungwa zvinhu.Inogona kukonzerwa nezvinhu zvakati wandei senge kusakwana kudzivirira gasi kufukidzwa, isina kufanira gasi kuyerera mwero, yakasvibiswa base simbi, kana zvisina kufanira welding matekiniki.Porosity inogona kunetesa weld uye kuderedza kushora kwayo kuramba.
2.Kutsemuka:
Kutsemuka kunogona kuitika mu weld kana munzvimbo yakakanganiswa nekupisa (HAZ).Kutsemuka kunogona kukonzerwa nezvinhu zvakasiyana-siyana senge kupinza kupisa kwakanyanya, kukurumidza kutonhora, preheating isiriyo kana interpass tembiricha yekudzora, yakawandisa yakasara kushushikana, kana kuvapo kwetsvina musimbi yepasi.Mitswe inogona kukanganisa kutendeseka kwechimiro che weld.
3.Kusanganiswa kusina kukwana kana kupinda kusina kukwana:
Kusanganiswa kusina kukwana kunoitika kana simbi yekuzadza isingabatanidzi zvachose nesimbi yepasi kana mabheji ari pedyo.Kupinda kusina kukwana kunoreva mamiriro ezvinhu apo weld haipindi kuburikidza nehukobvu hwose hwejoini.Izvi zvinokanganisa zvinogona kukonzerwa nekusakwana kwekupisa kwekuisa, nzira isiriyo yewelding, kana gadziriro isina kukodzera yemajoini.
4.Undercutting:
Undercutting ndiko kuumbwa kwegororo kana kuora mwoyo pamwe chete nechigunwe cheweld kana pedyo nacho.Inogona kukonzerwa nekunyanyisa ikozvino kana kumhanya kwekufamba, isina kukodzera electrode angle, kana isiriyo welding nzira.Undercutting inogona kuderedza weld uye kutungamirira kune kushushikana mupfungwa.
5. Yakawandisa spatter:
Spatter inoreva kudzingwa kwemadonhwe esimbi yakanyunguduka panguva yewelding.Yakawandisa spatter inogona kuitika nekuda kwezvinhu zvakaita senge yakakwira welding ikozvino, isiriyo yekudzivirira gasi kuyerera mwero, kana isina kukodzera electrode angle.Spatter inogona kukonzera kushata kweweld kutaridzika uye ingangoda imwe post-weld kuchenesa.
6.Distortion:
Kutsveyamisa (distortion) zvinoreva deformation kana kuputika kwesimbi yepasi kana yejoini yakasungwa panguva yewelding.Inogona kuitika nekuda kwekudziya kusiri-uniform uye kutonhora kwechinhu, kusakwana kugadzirisa kana kusungirira, kana kusunungurwa kwekunetseka kwasara.Kukanganisa kunogona kukanganisa kurongeka kwedimensional uye kukwana-up kweiyo welded components.
Kuti uderedze kukanganisa uku panguva yekukwirisa welding ye304 Stainless steel strip, zvakakosha kutevedzera nzira dzewelding, kuve nechokwadi chekugadzirira kwakabatana, kuchengetedza kupisa kwakaringana kupinza uye kudzivirira kufukidzwa kwegasi, uye kushandisa nzira dzakakodzera dzewelding.Pamusoro pezvo, pre-weld uye post-weld kupisa kurapwa, pamwe nenzira dzisiri dzekuparadza dzekuyedza, dzinogona kushandiswa kuona uye kudzikisira hurema.
