Qhov kev xyaum no yog tsim rau Chocky tuav nkaus xwb.
Lus Cim: Rau qhov nkhaus loj nrog lub vojvoog tsawg dua 305mm, lossis sab hauv nkhaus, nws raug nquahu kom muab cov hlau me me
rov qab phaj rov qab "V" los pab tsim. (Daim duab A)
Lub Chocky bar tuaj yeem tawg thaum khoov. Qhov no yog qhov qub.
1. Ntxuav qhov chaw uas chocky bar yuav welded.
2. Tack weld ib kawg ntawm chocky bar (raws li cov txheej txheem vuam) tsawg kawg yog 3 qhov chaw los ntawm 15mm yam tsawg kawg nkaus
ntev ib weld (Daim duab 1)
3. Sab nraum Curves: Rauj down unwelded kawg ntawm bar nrog ib tug mos ntsej muag rauj rau khoov bar kom phim mating
lub vojvoog. (Daim duab 2)
4. Sab hauv nkhaus: Pib qhov chaw tawm tsam nrog lub ntsej muag muag rau khoov bar kom phim mating vojvoog.
(Daim duab 3)
5. Txiav Cov Lus Qhia: Kev kub siab abrasive dej dav hlau txiav yog txoj kev txiav uas nyiam. Thermal txiav
Kev siv lub teeb oxyacetylene, arc-air lossis ntshav tsis pom zoo vim muaj cua sov hauv zos thiab siab.
kev pheej hmoo ntawm kev tawg, txiav los ntawm abrasive disc yog ib qho kev lees paub.
