1. Nhọrọ nke dayameta electrode

Nhọrọ nke dayameta electrode na-adabere na ihe ndị dị ka ọkpụrụkpụ nke welding, ụdị nkwonkwo, ọnọdụ nke weld na ọkwa nke ịgbado ọkụ.Na premise nke adịghị emetụta ịgbado ọkụ àgwà, iji melite ọrụ arụpụtaghị ihe, n'ozuzu na-ahọrọ a ibu dayameta electrode.

Maka akụkụ ịgbado ọkụ nwere oke buru ibu, ekwesịrị iji electrode dayameta buru ibu.Maka ịgbado ọkụ dị larịị, dayameta nke electrode ejiri nwere ike ibu ibu;maka ịgbado ọkụ kwụ ọtọ, dayameta nke electrode eji eme ihe abụghị ihe karịrị 5 mm;maka ịgbado ọkụ kwụ ọtọ na ịgbado ọkụ n'elu, dayameta nke electrode ejiri na-adịkarịghị karịa 4 mm.N'ihe gbasara ịgbado ọkụ multi-layer na oghere ndị yiri ya, iji gbochie mmebi nke ntinye ntinye na-ezughị ezu, a ga-eji electrode dayameta 3.2 mm mee ihe maka akwa akwa weld mbụ.N'okpuru ọnọdụ nkịtị, enwere ike ịhọrọ dayameta electrode dị ka ọkpụrụkpụ nke weldment (dị ka edepụtara na Tebụl TQ-1).
