welding txheej txheem ntawm steel qhov chaw ncej

Weld nto yuav tsum tsis txhob muaj kab nrib pleb los yog tsis xws luag.Thawj thiab theem nrab welds yuav tsum tsis txhob muaj qhov pores, slag clips, arc qhov tawg, arc abrasion thiab lwm yam tsis xws luag.Thiab thawj qib weld yuav tsum tsis muaj tom, tsis puv, hauv paus shrinkage thiab lwm yam tsis xws luag.Kev soj ntsuam kom muaj nuj nqis: 10% ntawm cov khoom zoo sib xws yuav tsum raug tshuaj xyuas, thiab tsis pub tsawg dua 3;ntawm cov khoom kuaj xyuas, txhua hom vuam yuav tsum raug tshuaj xyuas 5% los ntawm tus lej ntawm daim, thiab tsis pub tsawg dua 1;tag nrho cov chaw kuaj xyuas yuav tsum tsis pub tsawg tshaj 10.Inspection method: soj ntsuam los yog siv cov iav magnifying, weld gauge thiab steel gauge, nrog rau kev nkag los yog sib nqus particle test.


Product Detail

Khoom cim npe

Cov khoom siv vuam sib txuas yuav tsum sib phim nrog lub hauv paus hlau.Thaum ob qib steel sib txawv yog welded, cov electrode lossis hlau uas phim cov qib qis zog steel yog siv.Welded kev twb kev txuas nrog ncaj dynamic load los yog ib qho tseem ceeb tuab phaj vuam yuav tsum tau siv tsawg-hydrogen electrodes, xws li E4315, E4316, E5015, E5016 thiab lwm yam qauv.Fire retardant coatings yuav tsum yog cov khoom uas tau dhau qhov kev xeem ntawm lub teb chaws kuaj lub koom haum thiab tau kev pom zoo los ntawm lub tuam tsev tua hluav taws, thiab yuav tsum tau muab sib xyaw nrog cov primer.Kev ua tau zoo, txheej txheej thiab cov kev xav tau zoo ntawm cov txheej txheem hluav taws kub retardant yuav tsum ua raws li lub teb chaws tus qauv tam sim no "Fireproof Coatings for Steel Structures" (GB14907-2018) thiab lub teb chaws tus qauv tam sim no "Daim ntawv thov Technology ntawm Fireproof Coatings rau Steel Structures" (CECS24). -2020).

Lub vuam seam zoo soj ntsuam ntawm qhov chaw thav duab yuav tsum ua tau raws li cov txheej txheem thib ob uas tau teev tseg hauv <> (GB50205-2020).Cov qib zoo ntawm vuam yuav tsum ua raws li lub teb chaws tus qauv tam sim no "Code for Welding of Steel Structures" GB 50661 Txoj kev tshuaj xyuas yuav tsum ua raws li lub teb chaws tus qauv tam sim no "Code rau Txais Kev Tsim Kho Zoo ntawm Steel Structure Engineering" GB 50205. Rau pob tw welds nrog ib tug tuab ntawm tsawg tshaj li 6 hli, ultrasonic flaw detection yuav tsum tsis txhob siv los txiav txim lub weld zoo qib.6.Thaum cov yeeb nkab steel thiab cov phaj sealing thiab lub khob hliav qab lub taub hau tsim ib tug pas nrig, lub pob tw welds ntawm ob qho kawg yog tag nrho cov nkag welds.
