Makhalidwe ndi Ntchito
AWS A5.20 E70T-7Flux CoredMzereWaya wowotchereraNdi waya wodziteteza wokha womwe umapangidwira kuwotcherera kwambiri. Ndi woyenera malo athyathyathya, opingasa komanso otsika pa DCEN polarity. Kuchita bwino kwambiri poyang'ana X-ray, komanso desulfuration kumachepetsa ming'alu mu kuwotcherera mbale zokhuthala, malo olumikizirana ndi chitsulo chapakati-kaboni.
Ntchito zake ndi kupanga zinthu zonse ndi kulumikiza kwa kapangidwe komwe kumafunika kuyikapo kwakukulu ndi kulowa bwino komanso liwiro loyenda mwachangu. Malo omwe alipo ndi kulumikiza kwathyathyathya, kulumikiza kopingasa ndi kulowetsa koyima pansi kwa kulumikiza kwa fllet ndi lap joint.

Mankhwala Odziwika Bwino Opangidwa ndi Chitsulo Chosungunula (%)
C 0.29 Mn 0.45 Si 0.10 P 0.010 S 0.005 AI 1.45

Kapangidwe ka Makina Omwe Amagwiritsidwa Ntchito pa Chitsulo Chosungunula
Mphamvu yotulutsa 453Mpa Mphamvu yokoka 600MPa Kutalika 25%

Malangizo okhudza kugwiritsa ntchito:
1. DC(-) polarity ndi yabwino.
2. Pamene kulimba kwa chitsulo chosungunula kuli kofunika.
3. Sungani chinthucho chiume, pamene chikusungidwa kapena kutumizidwa.

Wenzhou Tianyu Electronic Co., Ltd. idakhazikitsidwa mu 2000. Takhala tikugwira ntchito yopanga ma electrode owotcherera,ndodo zowotcherera, ndi zogwiritsidwa ntchito zowotcherera kwa zaka zoposa 20.

Zogulitsa zathu zazikulu zikuphatikizapo ma electrode olumikizira zitsulo zosapanga dzimbiri, ma electrode olumikizira zitsulo za kaboni, ma electrode olumikizira zitsulo zosapanga dzimbiri, ma electrode olumikizira zitsulo zopindika, ma electrode olumikizira zitsulo zopindika, ma electrode olumikizira zitsulo zopindika ndi nickel & cobalt, mawaya olumikizira zitsulo zosapanga dzimbiri & low alloy, mawaya olumikizira zitsulo zosapanga dzimbiri, mawaya olumikizidwa ndi mpweya, mawaya olumikizira zitsulo zopindika, mawaya olumikizira zitsulo zopindika, mawaya olumikizira zitsulo zopindika ndi nickel & cobalt ... ndi mkuwa, mawaya olumikizira zitsulo zopindika ndi TIG & MIG, ma electrode a tungsten, ma electrode olumikizira zitsulo zopindika ndi kaboni, ndi zina zowonjezera ndi zogwiritsidwa ntchito.
