Pre-welding of straight seam steel pipe

  1. Musono wakabatana (kureva kuti, musono wekuumba) hauna mipendero isiriyo kana mipendero isiriyo ishoma pane yakataurwa kukosha. Kazhinji, huwandu hwemapendero asina kunaka huri pasi pe8% yehukobvu hweplate, uye huwandu hahuna kupfuura 1.5mm.

2. Kuti uve nechokwadi chekuti weld ine kudzika kwakakodzera kwekupinda uye deposition huwandu, zvinodikanwa kuve nechokwadi kuti haina kutsemuka kana kupisa mukati mushure mewelding, uye zvakare zvinodiwa kudzora kureba kweweld kuitira kuti weld kureba. weld yekunze haizokanganisike.

3. Iyo welding bead inoenderera uye yakaumbwa kuti ive nechokwadi chekunze welding mushure.

4. Musono welding hauna kukanganisa senge welding deviation, pores, cracks, slag inclusion, burn-through and back welding, and the center deviation from the welding seam inotarisirwa kuva ≤1mm.

5. Hapana arc inopisa, kuputika kudiki, uye hapana pesvedzero pane bevel uye pamusoro pepombi kupera.

6. Musono we welding unofananidzwa nesimbi yepasi, uye hunhu hwemuviri nemakemikari emushonga wesimbi welding unozadzisa zvinodiwa.
