Vuam kev ua haujlwm thiab kev tswj hwm kev tswj hwm

Electrode Manipulation

Rau lub tiaj vuam, siv cov oscillations me me lossis me me qis dua (oscillation amplitude tsawg dua los yog sib npaug ntawm cov pas dej loj me) kom tsis txhob muaj ntau lub taub dej.

Rau ntsug los yog overhead vuam, siv luv luv arcs thiab nqaim hla nrog me ntsis sai sai sai taug kev nrawm los tiv thaiv pas dej sagging lossis dripping. Feem ntau, "Zigzag" los yog daim duab cua nab kuab kom ua kom muaj kev sib dhos hauv pas dej kub.

Sau lub pob zeb thaum lub sij hawm ARC (siv cov txheej txheem butstep) kom tsis txhob tawg ua ke.

Kev Tswj Qhov Kub Kub
Rau multi -}}} dhau vuam, qhov kub thiab txias yuav tsum tau tswj hwm ntawm150 ~ 300 degree(kho raws li lub hauv paus hlau lub zog qib):

Ntau dhau high intral kub (> 300 degree): coarse weld hlau nplej thiab muaj teeb meem loj heev rau cov qauv muaj tsawg (piv txwv li, hauv qab -20 degree).

Ntau dhau qhov kev kub siab tshaj plaws (<150 degree): Kev ntxhov siab tsis txaus los ntawm kev sib txawv dhau los thiab kev pheej hmoo hydrogen diffusion, nce txoj kev pheej hmoo ntawm ncua kev tawg.

Siv tus pas ntsuas kub infrared rau tiag - lub sijhawm tshuaj xyuas. Ncua vuam kom txias yog tias kub dhau; Rov qab ua si hauv zos los phiaj kub yog tias underheating.

Kev Tshem Tawm Tshem Tawm thiab Kev Tu

Txhim kho slag tom qab txhua daim ntawv hla (siv chipping rauj lossis xaim txhuam), tshwj xeeb yog ua rau groove fab, kom tsis txhob muaj slag inclusion.

Cag hla dhau cov -}}} Hla vuam tu (siv carbon aring Tom qab tu, zom rau nws yog xim hlau luster thiab re - preheat.
