Inkqubo yokuwelda

1. Intsimbi engwevu--Sebenzisa i-welding encinci yangoku kunye nekhawulezayo ukunciphisa ubunzulu bokungena kunye ne-fusion ratio; sebenzisa i-welding short-section, i-welding intermittent, i-welding esasaziweyo, i-segmented backward welding, kunye ne-hammer weld; ulwalathiso lwe-welding kufuneka lube kuqala Qala ukuwelda ukusuka kwindawo enobunzima obuphezulu. ungakhetha Z308, Z408.

2. Intsimbi yentsimbi--Sebenzisa umsinga omkhulu: l=(30-60)D, i-welding eqhubekayo; ukuba kuyimfuneko, ukupholisa okucothayo emva kwe-welding kunokunyangwa ubushushu: ukulinganisa okanye ukucima. ungakhetha iZ408.

3. Intsimbi enyibilikayo etyhidiweyo - usebenzisa inkqubo efanayo kwintsimbi emdaka. ungakhetha iZ308.

4. I-Vermicular graphite cast iron - usebenzisa inkqubo efana ne-grey cast iron. ungakhetha iZ308.

5. Intsimbi emhlophe yentsimbi - usebenzisa inkqubo efana neyodwa yentsimbi ye-nodular cast. ungakhetha Z308, Z408.
