Chii chinonzi Welding Technology?

Welding inzira inobatanidza zvachose zvikamu zviviri zvakapatsanurwa kuita chimwe nekudziya kana kudzvanya kugadzira atomic bonding. Iyo inonyanya kukamurwa muzvikamu zvitatu: fusion welding, pressure welding uye brazing.

Fusion welding inoumba weld joints kuburikidza nekudziya uye kutonhora, kusanganisira yakadzivirirwa simbi arc welding, gasi simbi arc welding, undermerged arc welding, plasma arc welding, laser welding uye electron beam welding.

Sezvinoratidzwa nezita racho, pressure welding inojoinha maworkpieces kunyanya nekuisa kumanikidza kwekunze. Mhando dzayo dzakajairika dzinosanganisira resistance welding, friction welding, ultrasonic welding uye explosive welding.

Brazing inzira yekujoinha iyo inoshandisa simbi yekuzadza ine nzvimbo yekunyungudika yakaderera pane iyo yepasi zvinhu. Iyo inozadza inonyunguduka uye inozadza gaka rekubatana, iro rinowira mumhando mbiri huru: nyoro solder uye yakaoma brazing.

EHSSyakashongedzerwa nenzvimbo dzekugadzira dzepamusoro uye inyanzvi mune-ye-the-art welding matekinoroji akadai seakadzika arc welding michina uye CO₂ gasi shielded welding.Welds edu anosangana neClass 1 standard, iyo yepamusoro-soro giredhi yesimbi chimiro welds, iyo yakapfuura yakaomesesa kuongororwa pachitarisiko, kuremara kwemukati uye kusingaparadzi kuedza.

TS EN ISO 3834, yakadanwa zviri pamutemo Hunhu zvinodikanwa zvekusanganisa welding yemidziyo yesimbi, chiyero chepasirese chakatsaurirwa kune welding mhando manejimendi. EHSS yakawana chitupa cheISO 3834-2(Zvakakwana zvemhando zvinodiwa), kutevedzera zvizere zvinodiwa nemusika weEU. Isu tinotora yakakwira-standard welding maitiro kuendesa zvivakwa zvesimbi zvine mhando yepamusoro, kuchengeteka uye kuvimbika.
