1. Njikwa tupu ịgbado ọkụ:

1) A ga-ebu ụzọ nyochaa akụrụngwa, ma ọ bụ naanị mgbe ha gafechara nyocha ahụ, ha nwere ike ịbanye n'ebe a na-ewu ụlọ n'ụzọ nkịtị, ma jiri mkpebi siri ike jiri ígwè na-erughị eru.
2) Nke abụọ bụ njikwa nke ihe ịgbado ọkụ. Lelee ma ihe ndị a na-agbado ọkụ bụ ngwaahịa ndị ruru eru, ma a na-etinye ihe nchekwa na usoro ihe oriri, ma elu nke ihe ịgbado ọkụ na-ekesa ọ dị ọcha na nchara na-enweghị, ma mkpuchi nke mkpanaka ịgbado ọkụ adịghị na ma enwere mildew.
3) Nke atọ bụ njikwa dị ọcha nke ebe ịgbado ọkụ. Lelee ịdị ọcha nke ebe ịgbado ọkụ, na e kwesịghị inwe unyi dị ka mmiri, mmanụ, nchara na ihe nkiri oxide, nke na-arụ ọrụ dị mkpa n'ịgbochi ntụpọ mpụga na weld.
4) Iji họrọ usoro ịgbado ọkụ kwesịrị ekwesị, a ga-emejuputa ụkpụrụ nke ịgbado ọkụ nke mbụ na ịgbado ọkụ na-esote.

2. Njikwa n'oge ịgbado ọkụ:

1) Lelee ma nkọwapụta nke waya ịgbado ọkụ na flux ziri ezi dị ka ụkpụrụ usoro ịgbado ọkụ si dị iji gbochie iji waya ịgbado ọkụ na-ezighi ezi ma bute ihe mberede ịgbado ọkụ.
2) Na-elekọta gburugburu ịgbado ọkụ. Mgbe ebe ịgbado ọkụ adịghị mma (okpomọkụ dị ala karịa 0 ℃, iru mmiri dị elu karịa 90%), ekwesịrị ịme usoro kwekọrọ tupu ịgbado ọkụ.
3) Tupu tupu ịgbado ọkụ, lelee groove akụkụ, gụnyere gaps, kpuru n'ọnụ, akụkụ na ezighị ezi, ma ha izute usoro chọrọ.
4) Ma ịgbado ọkụ ugbu a, ịgbado ọkụ voltaji, ịgbado ọkụ ọsọ na ndị ọzọ usoro parameters ahọrọ na akpaka submerged arc ịgbado ọkụ usoro ziri ezi.
5) Na-elekọta ndị ọrụ ịgbado ọkụ ka ha jiri ogologo ogologo nke arc pilot na njedebe nke ọkpọkọ nchara n'oge ịgbado ọkụ na-akpaghị aka, na-ewusi arụmọrụ nke pilot arc efere n'oge ịgbado ọkụ n'ime na mpụga, nke na-enyere aka. melite ọkpọkọ ọgwụgwụ ịgbado ọkụ.
6) Na-ahụ maka ma ndị ọrụ ịgbado ọkụ na-ebu ụzọ kpochaa slag n'oge ịgbado ọkụ, ma a na-edozi nkwonkwo, ma enwere mmanụ, nchara, slag, mmiri, agba na unyi ndị ọzọ na oghere.
