- Ntawm cov khoom uas xav tau kev qaug zog, tag nrho cov pob tw welds yuav tsum tau nkag mus, thiab lawv qib zoo yog:
1) Transverse pob tw welds los yog ua ke T-zoo li lub pob tw thiab fillet welds qhov twg lub zog yog perpendicular mus rau qhov ntev ntawm weld yuav tsum tau muab cais raws li theem 1 thaum nyob rau hauv nruj nreem thiab Qib 2 thaum nyob rau hauv siab;
2) Longitudinal pob tw welds qhov twg lub zog sib npaug mus rau qhov ntev ntawm qhov vuam yuav tsum yog Class II.
- Rau cov khoom uas tsis tas yuav tsum tau suav rau kev qaug zog, pob tw welds uas yuav tsum muaj zog npaum li cov hlau hauv paus yuav tsum tau welded los ntawm, thiab lawv cov qib zoo yuav tsum tsis txhob qis dua qib 2 thaum nyob rau hauv qhov nro, thiab yuav tsum yog Qib 2. thaum nyob hauv siab.
- Lub T-shaped sib koom welds ntawm lub vev xaib thiab L ntug ntawm lub crane nqaj nrog lub zog ua haujlwm hnyav thiab nqa lub peev xwm Q Ntau dua lossis sib npaug li 50t, thiab nruab nrab ntawm chord sab sauv ntawm lub crane truss thav duab thiab lub phaj gusset yuav tsum tau nkag mus. Daim ntawv weld feem ntau yog ib qho kev sib txuas ntawm pob tw thiab fillet welds, thiab nws cov qib zoo yuav tsum tsis txhob qis dua Qib 2.
- Cov qib zoo ntawm fillet welds siv nyob rau hauv 'Kuv'-zoo li cov pob qij txha uas tsis tas yuav tsum tau nkag los yog ua ke pob tw thiab fillet welds nrog ib feem nkag mus, nrog rau cov fillet welds siv nyob rau hauv lap sib txuas, yog raws li nram no:
1) Rau cov qauv uas ncaj qha dais dynamic loads thiab yuav tsum tau qaug zog pov thawj thiab nruab nrab ua hauj lwm crane beams nrog ib tug crane nqa peev xwm sib npaug los yog ntau tshaj 50t, cov tsos zoo qauv ntawm cov welds yuav tsum ua raws li theem 2;
2) Rau lwm cov qauv, cov qauv zoo ntawm welds tuaj yeem yog Qib 2.
Kev tshuaj xyuas qhov tshwm sim feem ntau yog ua kom pom qhov muag. Kev tshuaj xyuas tawg yuav tsum tau ua nrog 5x lub iav tsom iav thiab nyob rau hauv cov teeb pom kev zoo. Magnetic particle soj ntsuam los yog kev soj ntsuam penetrant tuaj yeem siv thaum tsim nyog. Cov cuab yeej ntsuas thiab snap gauges yuav tsum tau siv los ntsuas qhov ntev.
