Mma: iimpawu kunye nokubekwa

Manual arc welding ke ngoko igama kuba onke amanyathelo afunekayo zentsimbi specialist ngesandla. Unoxanduva lokudala nasekuzinziseni i arc, i arc intshukumo lomfowunelwa phezu lekhefu ofunekayo, nangoncedo electrode esitsha endaweni ye kusetyenziswa. kwizinga Weld kuxhomekeke wobuchule kopi. Kufuneka ngokukhawuleza phemba i arc, ukubeka esweni ngokusondeleyo kangangokuba ubude baso efanayo, kwakunye ukuvelisa i welding efanayo iinxalenye ezimbini.

Mma has a kudidi ethile. Umzekelo, ngokwenani of electrode kusetyenziswa weld ukwahlula electrode elinye okanye amabini, kwaye multi-electrode. Kukho-isigaba ezintathu nabangatshatanga-phase arc, umlinganiswa yangoku inokuba AC okanye DC.

Kungoku nje ngokubanzi welding kunye ifildi okanye ngoku ngqo usebenzisa eziphelayo electrode. Kakade ke, kukho iindlela ezininzi ezahlukeneyo ukudibanisa amacandelo ukuwelda. Umzekelo, ukwenza iintlobo ezahlukeneyo amalungu (ezinemiphetho flanged). Ukwandisa imveliso ekucetyiswa ukusetyenziswa electrode ze umqadi, kunye nokudibanisa iintsimbi aluminiyamu ezahlukeneyo zesinyithi non-ayoni ezi electrode Tungsten.

Mma abe inkqubo yokuvelisa ethile. Xa kusetyenziswa electrode ukuwelda kwiindawo ezahlukahlukeneyo, nto leyo ibe eziphelayo nonconsumable. ukuze Owayesakuba ezenziwe ngocingo kunye ukutyabeka okhethekileyo. ukutshiza enjalo kuyimfuneko ukuba iqondo eliphezulu lozinzo ye arc lombane ukunika ligwebu metal komhlaba kunye oxides ekhusela pool weld evela intsebenziswano kunye nokusingqongileyo, nokukhusela arc ukusuka kwindawo yokuxhulumana kunye nomoya.

Manual TIG iwelding kudlalwa kule iimeko ezahlukeneyo okukufutshane kunye neegesi ezahlukeneyo. Umzekelo, manual argon-arc welding (kwimeko ka argon), welding umoya t. D.

Ngokutsho GOST 9466-75, i electrode ziye zohlulwa ngokwendidi eziliqela.

1. ngu baqeshwe:

• kunye onekhaboni ephantsi-ingxubevange yodidi zezakhiwo;
• aluminiyamu eyomeleleyo;
• ubushushu-resistant ingxubevange yesinyithi;
• uqhagamshelwano lwetshiphu emsebenzi-ingxubevange yodidi zezakhiwo.

2. Ngokutsho uhlobo brand:

• eqhelekileyo;
• siko.

3. Njengoko Ebubanzini ukutyabeka itshizwe:

• olomileyo,
• avareji;
• yesithokothoko;
• ngakumbi obukhulu.

4. Xa zokwaleka uhlobo electrode:

• acid;
• rutile;
• kwincindi;
• enamathela powder yentsimbi.

5. isikhundla kuvumelekile lwendawo i electrode:

• ngazo naziphi na izibonelelo;
• na, ngaphandle iwelding nkqo manual;
• ngokuba oxwesileyo ezisezantsi kwi-moya nkqo;
• ngokuba emazantsi "kwi iphenyane."

6. ezichaseneyo ye welding yangoku kusetyenziswa:

• ngqo;
• ukulungisa;
• nayiphi na.

7. Xa nohlobo iwelding yangoku:

• ngokusisigxina;
• AC.

Mma icebisa ukuba metal nto nge welding electrode, kufuneka ube sisincoko imichiza ihambelana neemfuno zayo. Ezona mpawu mechanical onesiphumo weld kunye weld metal kufuneka kuziswa lungqinelane naloo GOST 9467-75.
