Welding txheej txheem muaj peev xwm (Vuam cov txheej txheem tsim nyog, hu ua WPQ) yog cov txheej txheem xeem ntawv thiab kev ntsuas cov txiaj ntsig rau kev kuaj xyuas qhov tseeb ntawm cov lus pom zoo txuas nrog vuam txheej txheem.

Welding txheej txheem kev tsim nyog yog ib qho kev ntsuas tseem ceeb kom ntseeg tau tias qhov zoo thiab muab lub hauv paus kom ntseeg tau ntawm kev tsim cov txheej txheem vuam cov txheej txheem lossis vuam txheej txheem vuam.

I. Ptso tseg

1. Txheeb xyuas seb lub tshuab xaim txuas puas muaj peev xwm los txuas cov pob qij txha uas ua tau raws li cov kev cai ntawm kev ua haujlwm hauv teb chaws lossis kev lag luam thiab kev qhia tshwj xeeb;

2. Txheeb xyuas tias qhov vuam txheej txheem kev faib tawm (WPS lossis pWPS) kos los ntawm vuam chav ua haujlwm yog.

3. Muab qhov txheej txheem txhim khu kev qha rau kev tsim qauv ntawm txheej txheem vuam cov txheej txheem lossis vuam cov txheej txheem sib tw.

II. Qhaqho tsis quav ntsej

Vuam cov txheej txheem yog qhov kev ntsuas tseem ceeb kom ntseeg tau qhov zoo ntawm vuam. Nws tuaj yeem lees tias qhov tseeb thiab qhov sib npaug ntawm cov txheej txheem vuam cov txheej txheem npaj rau ntau yam pob hlau txuas. Los ntawm kev vuam txheej txheem kev tsim nyog, tshawb xyuas seb qhov ua tau zoo ntawm welded pob qij txha welded raws li daim ntawv cua sov vuam txheej txheem cov lus qhia ua tau raws li cov qauv tsim, thiab muab lub hauv paus kom ntseeg tau rau kev tsim cov txheej txheem ntawm vuam txheej txheem phau ntawv lossis vuam txheej txheem daim npav.

III. Cov tau txais daim ntawv thov

1. Nws tsim nyog rau kev tsim khoom, teeb tsa thiab kho cov cuab yeej steel xws li lub rwj dej, lub nkoj siab, lub raj xa dej siab, txuas hniav, nkoj, chaw tsim khoom, lub zog nuclear thiab load-bearing steel qauv.

2. Tsim nyog rau txoj kev siv vuam xws li roj vuam, electrode arc vuam, argon tungsten arc vuam, roj hlau arc vuam, subcated arc vuam, plasma arc vuam, thiab electroslag vuam.

IV. Txheej Txheem

1. Vuam txheej txheem kev tsim nyog

2. Tshaj tawm cov khoom rau vuam txheej txheem kev tsim nyog

3. Daim qauv phiaj xwm vuam txoj kev npaj

4. Vuam txheej txheem kev kuaj xyuas qhov ua tau zoo

5. Kev npaj ntawm vuam txheej txheem kev tsim nyog daim ntawv qhia

6. Kev muab tso ua ke ntawm txheej txheem kev siv vuam (cov lus qhia ua haujlwm rau cov txheej txheem ua daim npav thiab cov txheej txheem ua daim npav)

V. Kev soj ntsuam tus txheej txheem

1. Sau daim ntawv sib tw ua ntej txheej txheem vuam txwv (pWPS)

2. Vuam xeem tej daim thiab qauv coj mus kuaj

3. Kuaj cov quav thiab kuaj

4. Txheeb xyuas seb qhov sib koom tes welded ua tau raws li cov kev ua tau zoo raws li tus qauv

5. Xa daim ntawv teev cov txheej txheem tsim nyog vuam los soj ntsuam kev thov qhia kev ua haujlwm vuam cov txheej txheem
