Kufungisisa kwakajairika kuremara kwekutya kwesimbi isina tsvina, iyo inoratidzwa semakomba madiki muWeld, inokanganisa kusimba uye simba re pombi. Iyi inotevera nzira iri nyore-kune-nzira yekutsanangura zvinokonzeresa zve stomata uye maitiro ekuita navo:
1. Pores vanobva kupi?
1.1 gasi rakasara
Iyo simbi iyo inonyungudika panguva yeWelding inotora magasi akatenderedza (senge oksijeni uye nitrogen mumhepo).
Kana iyo gasi rekuchengetera (senge argon) isina kukwana kana isina kukwana zvakakwana, magasi aya haakwanise kudzingwa nguva yadarika kana simbi ikapetwa, kugadzira mabhuru.
1.2 zvinhu hazvina kuchena
Kune mafuta, madhiri emvura kana ngura pamusoro penzvimbo yesimbi, uye gasi rakadai se hydrogen yakaderedzwa pakupisa kwakanyanya uye yakasanganiswa muWel.
1.3 Zvisimusi Zvekushandisa
Iyo yazvino yakanyanya kukura uye kumhanya kwakanyanya kukurumidza: tembiricha yedziva rakanyungudutswa rakanyanya kana kuti kusimbisa kwakanyanya, uye gasi harigoni kupukunyuka.
Akasarudzika kona yeTorch Torch: Gasi rekudzivirira rinobviswa nemhepo, uye mhepo inopinda mudziva remberi.
2. Maitiro ekudzivirira makomba emhepo?
2.1 Yakachena Zvakanaka
Mafuta akachena, ngura uye unyoro kubva pamusoro penyo pombi zvakakwana ne sandpaper kana doro usati waenda.
2.2 Kudzora Kuchengetedza Gasi
Argon nekuchenesa ≥99.99% inoshandiswa uye kuyerera kuyerera kunochengetwa pa15-20l / min.
Ngwarira kusimbisa munzvimbo yakasimba yemhepo, iyo inogona kuvharidzirwa nehodhi yemhepo.
2.3 Rongedza ma parameter
Sarudza yakakodzera yazvino (yakadai se 90-120a ye1.2mm yemhepo waya) kuti udzivise zvakawandisa.
Welding kumhanya yunifomu, kwete nekukurumidza (8-12cm / min inokurudzirwa).
2.4 Sarudza Butt Welding zvinhu
Shandisa waya ine silicon (si) kana titanium (ti), senge er308li, kubatsira kubvisa gasi.
Flux-yakadzvanywa waya ine porosity porosity kuramba pane waya yakasimba.
2.5 Kushanda Unyanzvi
Chengetedza kona pakati peTorch Torch uye working nezve 75 ° kuve nechokwadi chekuti gasi rinofukidza dziva rakanyungudutswa.
Iyo porosity inonyanya kukonzerwa negesi zvakasara uye zvisina kukodzera kushanda. Nekuchenesa izvo zvinyorwa, kudzora gasi uye kugadzirisa iyo paramita, iwe unogona kwazvo kuderedza porosity uye uve nechokwadi chekurarama kweiyo nongwe!
