1. Welding ugbu a na ume oge
Dị ka nha nke ịgbado ọkụ ugbu a na ogologo oge ike ume, ntụpọ ịgbado ọkụ nwere ike kewaa abụọ ụdị: ike nkọwapụta na nro nkọwapụta.Nkọwapụta nke na-agafe nnukwu ugbu a n'ime obere oge ka a na-akpọ nkọwa siri ike.Ọ nwere uru nke nrụpụta dị elu, ogologo ndụ electrode, na obere nrụrụ nke weldment.Ọ dabara maka ịgbado ọla na mma thermal conductivity.Nkọwa nke na-agafe obere ugbu a maka ogologo oge ka a na-akpọ nkọwa dị nro, nke nwere obere arụpụtaghị ihe ma dị mma maka ịgbado ígwè na-emekarị ka ọ sie ike.
2. Electrode mgbali
N'oge ịgbado ọkụ ntụpọ, nrụgide electrode na-etinye na weldment ka a na-akpọ nrụgide electrode.Ekwesịrị ịhọrọ nrụgide electrode nke ọma.Mgbe nrụgide dị elu, porosity shrinkage na oghere shrinkage nke nwere ike ime mgbe ngwut siri ike nwere ike ikpochapụ, ma njikọ njikọ na njupụta ugbu a na-ebelata, na-akpata ezughị ezu kpo oku nke weldment na mbelata na dayameta nke nugget solder nkwonkwo.Ike nke nkwonkwo solder na-ebelata.Enwere ike ịhọrọ oke nrụgide electrode dị ka ihe ndị a:
