Ni iki kigomba kwitonderwa mugihe argon arc gusudira ibyuma bitagira umwanda?

Ingingo zikurikira zizitonderwa mugihe ukoresheje gusudira arcon:

1. Amashanyarazi afite vertical vertical iranga iremewe, kandi polarite nziza yemewe muri DC (insinga yo gusudira ihujwe na pole mbi).

2. Mubisanzwe birakwiriye gusudira amasahani mato munsi ya 6mm, hamwe nibiranga imiterere myiza yo gusudira hamwe no guhinduranya gusudira.

3. Gazi ikingira ni argon ifite ubuziranenge ≥ 99.95%.Iyo gusudira ari 50 ~ 150A, umuvuduko wa argon ni 6 ~ 10L / min, naho iyo ari 150 ~ 250A, argon itemba ni 12 ~ 15L / min.Umuvuduko wuzuye mumacupa ntushobora kuba munsi ya 0.5MPa kugirango wizere neza ko kuzuza argon.

4. Uburebure bwa tungsten electrode isohoka muri gaz nozzle nibyiza ko ari 4 ~ 5mm, 2 ~ 3mm ahantu hafite ingabo mbi nko gusudira kuzuza, 5 ~ 6mm ahantu hafite ibiti byimbitse, kandi intera kuva kuri nozzle kugeza kumurimo ni muri rusange ntibirenza 15mm.

5. Kugirango wirinde ko habaho imyanda yo gusudira, irangi ryamavuta, umunzani hamwe ningese kurukuta rwimbere ninyuma yibice byo gusudira bigomba gusukurwa.

6. Uburebure bwa arc bwo gusudira ibyuma bidafite ingese ni 1 ~ 3mm, kandi ingaruka zo kurinda ntabwo ari nziza niba ari ndende cyane.

7. Mugihe cyo gusubiza inyuma, kugirango wirinde inyuma yisaro ryasizwe munsi ya okiside, inyuma nayo igomba gukingirwa na gaze.

8. Kugirango urinde icyuzi cyo gusudira neza hamwe na argon no koroshya imikorere yo gusudira, inguni iri hagati yumurongo wo hagati wa tungsten electrode hamwe nakazi kakozwe kumwanya wo gusudira igomba gukomeza kubikwa kuri 75 ~ 85 °, hamwe nu mpande zirimo kuzuza. Ubuso bwibikoresho hamwe nibikorwa bigomba kuba bito bishoboka, mubisanzwe munsi ya 10 ° yubugari bwurukuta kandi ntibirenze 1mm.Kugirango umenye neza ko gusudira gukomera, witondere ubwiza bwiza bwo guhuza ingingo, hanyuma wuzuze pisine yashonze mugihe arc ihagarara.
