Pipe Welding Procedure

Pasi pepombi yakashongedzerwa kubva kumusoro kwearc, kubva kumusoro kusvika kuzasi zvese-zvinzvimbo-welding tekinoroji, nzira yewelding kumhanya, weld kutaridzika, yakanaka welding mhando, unogona kuchengetedza welding zvinhu, kuderedza kushanda kwakanyanya, inova yakajairika SMAW inogona. kwete kuenzaniswa uye ikozvino zvakanyanya kushandiswa muhombe-caliber kureba kwepaipi welding mune yese nzvimbo yesimba mukuvaka yakaderera-welded yakakura dhayamita yakatetepa-yakavezwa chubhu ine imwe yekushambadzira ukoshi.

 

Pasi pewelding kazhinji sarudza yakakodzera welding ikozvino, electrode angle uye welding speed, yakananga kuburikidza nekukwevera pasi kana kudzvinyirira arcing swing zvishoma kuti upedze welding. Welding electrode prone drip drip simbi yakanyungudutswa uye slag pasi pemubvunzo, uye kushandiswa kwepombi yakatsaurirwa kune welding electrode, welding yakatarwa yakasimbiswa zvakanyanya, unogona kugadzirisa matambudziko aya. Cellulose mhando electrode welding slag shoma, arc simba, kuomarara zvakakwana kudzivirira yakanyungudutswa slag uye kudonha pasi uye inopinda arc yakakura, kunyanya kune makobvu-ane madziro emidziyo uye welded simbi pombi yakarova pasi, unogona kubvisa mudzi wefoshoro kushanda, nokudaro uchivandudza basa. kushanda zvakanaka, kunatsiridza mamiriro ekushanda, asi nekuda kweiyo yakakwira hydrogen yemukati meweld, saka kune yemba yakakwira-kumanikidza pombi welding ikozvino inowanzoshandiswa cellulose electrode backing plus low hydrogen electrodes uye filler cap surface welding.

 

Iyo chaiyo seti yemachubhu uye tack welding iri pakuona kunaka kweiyo welding, kumashure kweiyo yakanaka weld chinhu chakakosha. Tack welding seam chikamu chechimiro, kwete chete chinoda kuumba mativi welding, asiwo kuve nechokwadi chemhando yewelding. Tack welding kureba 20mm, ukobvu hunosvika 3mm, materu akapfava pamativi ese eweld anofanirwa kukuyiwa kuita chimiro, kuitira kuti agone kubatanidzwa.
Pedyo neiyo welding electrode yakakosha kushandisa kona chaiyo. Kutsigira weld, kuzadza uye capping rod angle yakangofanana, asi iyo arc kureba uye kutakura kweimwe fomu. Pedyo neiyo weld, iyo weld inodzorwa nehurefu uye hupamhi hwemhando huru dzekutakura kwearc, arc uye arc kutarisisa kune nzvimbo isiriyo kunofanira kuvhurwa.
