Spiral Pipe (saw simbi pombi): nemutsetse nemupumburu wekugadzira muchina, kupeta spiral kutungamira, uyezve maviri-mativi akanyudzwa arc welding inogadzirwa kuburikidza necapacitor.Spiral welded simbi pombi yekugadzira maitiro, anowanzo kudonha muzviitiko zvakawanda, senge welding uye divi risiri iro.Nekudaro, mune izvi zviitiko zvinoonekwa Chlamydia ndiyo yakanyanya kuoma kubata spiral simbi butt weld.

Izvo zvinonzi trachoma: kuti iyo yekugadzira mukati mukati meiyo weld kana welds, hakuna kumbove nekunyatsopinda kwezvimedu kana mabhuru, pamwe chete nechimiro chegomba rejecha riri pamusoro peiyo weld.Zvikonzero zvetrachoma ndezvi:
1, kugoverwa kwetochi yewelding panguva yezvino idiki, iyo capacitor ipfupi kwazvo, iyo capacitor haina kunyatso kurongeka kana welding welding surface yakaomeswa, saka panoitika kupinda kwejecha kana kwete mabhubhu.
2, scimitar tune mujira-yakaita curvature yenguva pasina yakanaka butt, butt strip haienderane chaizvo, pakave nemukaha wakawandisa pakati pebutt strip.
3, butt welded simbi kana mativi maviri asina kuchenesa mupendero we strip rust kana chiyero.
4, hapana nguva yekugadzirisa yekugadzira michina yekuchenesa.Workbench guruva kana tsvina, zvisizvo kuwira mugomba pane butt welding yesimbi.
5, tembiricha yekushanda yakadzikira kana kunyorova musangano, izvo zvinokanganisa tembiricha uye kuoma kwewelding point.
