Litšitiso tse atisang ho etsahala sebakeng se ka tlas'a metsi arc welding li kenyelletsa li-pores, mapetsong a mocheso, le li-undercuts.

1. Li-bubble. Hangata li-bubble li hlaha bohareng ba chese. Lebaka le ka sehloohong ke hore haedrojene e ntse e patiloe ka tšepe e cheselitsoeng ka mokhoa oa li-bubble. Ka hona, mehato ea ho felisa sekoli sena ke ho tlosa mafome, oli, metsi le mongobo pele ho terata ea welding le weld, 'me ea bobeli, ho omisa flux hantle ho tlosa mongobo. Ho phaella moo, ho eketsa hona joale, ho fokotsa lebelo la ho cheselletsa, le ho fokotsa lebelo la ho tiisa tšepe e qhibilihisitsoeng le hona ho sebetsa haholo.

2. Mapetso a sebabole (mapetso a bakoang ke sebabole). Ha tjheseletsa lipoleiti tse nang le lihlopha tse matla tsa ho arola sebabole (haholo-holo tšepe e belang e bonolo), li-sulfide sehlopheng sa ho arola sebabole li kena ka tšepe ea weld 'me li baka mapetsong. Lebaka ke hore ho na le ntlha e tlase e qhibilihang ea sulfide ea tšepe sehlopheng sa ho arola sebabole le hydrogen ka har'a tšepe. Ka hona, ho thibela boemo bona hore bo se ke ba etsahala, hoa sebetsa ho sebelisa tšepe e bolailoeng ka halofo kapa tšepe e bolailoeng ka lihlopha tse fokolang tsa ho arola sebabole. Taba ea bobeli, ho hloekisa le ho omisa bokaholimo ba weld le flux le tsona lia hlokahala haholo.

3. Mapetsong a mocheso. Ha ho cheselletsoa ka tlas'a metsi, mapetsong a mocheso a ka hlaha ka har'a weld, haholo-holo mekoting ea arc qalong le qetellong ea arc. Ho felisa mapetsong a joalo, hangata li-pads li kenngoa qalong le qetellong ea arc, 'me qetellong ea li-coil welding tsa poleiti, pipe e entsoeng ka spiral e ka khutlisetsoa morao' me ea kenngoa ka har'a ho kopana. Maqhoa a mocheso a bonolo ho etsahala ha khatello ea weld e le khōlō haholo kapa tšepe ea weld e phahame haholo.

4. Ho kenyelletsoa ha Slag. Ho kenngoa ha slag ho bolela hore karolo ea slag e sala ka tšepe ea weld.

5. Ho se kenelle hantle. Ho kopana ha litšepe tse ka hare le tsa ka ntle ha hoa lekana, 'me ka linako tse ling ha ho chesetsoe. Boemo bona bo bitsoa ho kenella ho sa lekaneng.

6. Undercut. Undercut ke groove e bōpehileng joaloka V moeling oa weld haufi le mola o bohareng oa weld. Undercut e bakoa ke maemo a sa nepahalang joalo ka lebelo la welding, hajoale, le voltage. Har'a bona, lebelo le phahameng haholo la tjheseletsa le na le monyetla oa ho baka mefokolo e tlase ho feta ea hona joale e sa lokelang.
