Yog welding electrodes nqus dej noo ntawm cov dej ntws, nws tuaj yeem ua rau cov npuas tsim nyob hauv qhov txuas.

Tom qab ntawd, ib tus tuaj yeem nug, cov vuam txuas tsis zoo?

Yog, a welding pas nrig tuaj yeem ua tsis zoo . 7018 vuam pas nrig paub txog mus phem ceev tshaj plaws. Qhov no yog vim qhov tsis nkag siab rau cov dej noo. Tsis muaj kev khaws cia zoo rau 7018 vuam pas nrig , lawv tau tawg los yog ua rau tsis muaj txiaj ntsig nyob rau lub sijhawm.

Tsis tas li ntawd, welding rods yuav kav ntev npaum li cas? Yuav ntev npaum li cas lawv zaum kawg hauv kev khaws cia,,, nyob qhov twg los ntawm ib lub lis piam mus rau 25 xyoo,, nyob ntawm seb leej twg ua kev khaws cia thiab lawv li cas ua nws,,,, muaj yog tsis muaj BBF hnub tim vuam pas nrig ,, paj rods xws li 6010, 6011, yuav tsum khaws cia hauv chav sov rau ntau xyoo thiab tseem ua haujlwm zoo,, lwm yam rods xav tau sov sov yog tias lub pob yog qhib

Ua qhov no hauv kev txiav txim siab, koj puas paub thaum Weld tsis zoo?

  5. Tawg.
  6. Ntau globules ntawm hlau.
  7. Ua tsis tiav fusion.
  8. Oversized lossis undersized vuam kab.

Ntev Electrodes ntev npaum li cas?

Cov pob uas tsis tau qhib hluav taws xob muaj lub neej txee ntawm kwv yees li 15 txog 24 lub hlis nyob ntawm seb hnub tas sij hawm tau teev tseg ntawm pob khoom. Tsis txhob siv hluav taws xob uas yog yav dhau los hnub tas sij hawm
