Ọdịiche dị n'etiti TIG, MIG na MAG ịgbado ọkụ
1. TIG welding bụ n'ozuzu ọkụ ịgbado ọkụ nke a na-ejide n'otu aka na waya ịgbado ọkụ na nke ọzọ, nke kwesịrị ekwesị maka ịgbado ọkụ nke obere ọrụ na nrụzi.
2. Maka MIG na MAG, a na-eziga waya ịgbado ọkụ site na ọkụ ịgbado ọkụ site na usoro nri nri na-akpaghị aka, nke kwesịrị ekwesị maka ịgbado ọkụ na-akpaghị aka, na n'ezie enwere ike iji ya mee ihe.
3. Ọdịiche dị n'etiti MIG na MAG bụ tumadi na gas nchebe. Ngwá ọrụ ahụ yiri nke ahụ, ma nke mbụ na-echebe ya site na argon, nke kwesịrị ekwesị maka ịgbado ígwè na-abụghị ígwè; A na-ejikọta nke ikpeazụ na carbon dioxide gas na-arụ ọrụ na argon, ọ dịkwa mma maka ịgbado ígwè dị elu na ígwè dị elu.
4. TIG na MIG bụ inert gas na-echebe ịgbado ọkụ, nke a na-akpọkarị argon arc welding. Gas inert nwere ike ịbụ argon ma ọ bụ helium, mana argon dị ọnụ ala, ya mere a na-ejikarị ya eme ihe, ya mere a na-akpọkarị ịgbado ọkụ argon arc.
