Spiral weld seam ine anotevera marudzi akati wandei:

1. Spiral strip end weld: simbi musoro kuti spiral weld pamusoro simbi kana simbi weld musoro nemuswe;
2. Two spiral butt weld: spiral cut is kubatanidza zviviri izvi pamwechete kuita annular weld;
3. Spiral tack welding: iyo inoshandiswa pamberi pekupedzisira welding.For fixed butt weld edges.

Parametric yekuongorora ye welding seam
⑴ weld width inoreva panosangana weld surface uye base metal inonzi weld toe.The single-pass weld cross-section, chinhambwe pakati pezviviri chinonzi musono weld upamhi hwechigunwe.

⑵ mhiri kwepamusoro peiyo weld reinforcement inoreva kubatanidza pahurefu hwechigunwe chechigunwe cheweld simbi inonzi kusimbisa.Ini ndinogadzira chikamu chemuchinjiro we weld seam yekuwedzera kwepamusoro kwekutakura kugona kunowedzerwa, uye inogona kuwedzera kunzwisiswa kwe ray radiography, asi ichaita weld toe stress concentration.Kazhinji zvinoda zvinopfuura zvakakwirira kwete zvishoma pane zvinyorwa zvepasi, zvichiwedzera kukora kwayo uye kuwedzera urefu hwezvinhu zvaamai, asi huwandu hunofanira kudarika 3mm.

⑶ kupinda muchinjiko-chikamu chejoini yakasungwa, iyo base zvinhu inonzi kudzika kwekupinda kweyakanyungudutswa.Imwe kukosha kwekuona kuti iyo yakasanganiswa yekupinda weld uye base simbi simba.Kana iyo yekuzadza simbi zvinhu (tsvimbo kana waya) ichigara, kudzika kwekupinda kunotarisa saizi ye weld chemistry yakanyanyisa.Nzira dzakasiyana-siyana dzekuputira dzinoda kukosha kwekupinda kwakasiyana, semuenzaniso welding, surfacing layer kuitira kuchengetedza kuomarara uye kuderedza kuderedzwa kwesimbi yepasi ye weld, muchimiro chekuona kupinza kunofanirwa kudzika kudiki kwekupinda.
