Isishwankathelo solwazi malunga nokuguqulwa kokungunda kunye ne-welding

1. Ukwahluka kwesikhumba kunye nombala, amabala e-welding

Isizathu 1 : Izinto eziphathekayo zendawo ye-welding zihluke kwizinto zokuqala.

Amanyathelo ahambelanayo: Sebenzisa i-welding wire ehambelana nesiseko sezinto ezisisiseko, ngokukhethekileyo ucingo olukhethekileyo lwe-welding olusetyenziswa kwiintsimbi zetsimbi; okwesibini, wabona izinto ezivela kwizinto ezisisiseko; okanye usebenzise i-universal welding wire.

Isizathu sesi-2 : Ukunyangwa kokushisa kwendawo ye-welding kuhluke kwindawo yokuqala, kwaye isakhiwo sitshintsha.

Amanyathelo ahambelanayo: Unyango olushushu lwenziwa emva kwe-welding ukwenza ulwakhiwo lweenkozo luhambelane; iindawo ezibalulekileyo ziqhutywa ngokungqongqo ngokwenkqubo yentsimbi yentsimbi.

2. Iintanda kunye nokuguqulwa

Isizathu: Xa iinxalenye ziphantsi kwe-argon arc welding, zigqithisekile kwindawo, zibangele ukushisa okuhlukeneyo kwiindawo ezahlukeneyo zamacandelo kunye nokuvelisa uxinzelelo lwangaphakathi lwe-thermal; emva kwe-welding, indawo esecaleni kwendawo ye-welding ngokwenene iyacinywa, kwaye le ndawo inzima kakhulu kwaye ijwayele ukuqhekeka.

Phawula:

1. Ubukhulu bendawo ye-welding, inkulu uxinzelelo lwangaphakathi olwenziwe.

2 Ukuphakama kwekhabhoni kunye nomxholo we-alloying element, kokukhona ukuqina kwe-weldability. Ukuba idlula i-0.4%, i-preheating kunye ne-post-heating iyadingeka.

3. Ukuphakama kobunzima benxalenye, inkulu uxinzelelo lwangaphakathi lwangaphakathi kwaye kulula ukuqhekeka.

4. Ubukhali bemilo, kulula ukuba inxalenye yokuqhekeka.

Amanyathelo ahambelanayo: Preheat yonke kwaye wenze ubushushu emva kwe-welding.

Phawula:

Ukufakwa okukhulu, ukwenzela ukuba ugweme uxinzelelo olubangelwa ukushisa kwangaphambili (nokuba yonke inxalenye ifudumala, ukushisa kwenxalenye kuphuma ngaphandle ukuya ngaphakathi, okusenokubangela uxinzelelo lwangaphakathi) , Xa ufudumala, gcina ukufudumala kwiqondo lokushisa eliphakathi kwithuba elithile ngaphambi kokufudumeza kwakhona.

3. Imingxuma yesanti kunye neepores

Isizathu soku-1 : Iingxaki zobugcisa be-welder, izikhewu ekuqokeleleni kwe-weld point.

Amanyathelo ahambelanayo: Sebenzisa iintonga ze-welding kangangoko kunokwenzeka; Qaphela kwaye ulumke xa u-welding.

Isizathu sesi-2 : Xa iindawo ezine-nitrided zidityanisiwe, iimolekyuli zenitrogen ziyaba ngumphunga kwaye zenze iipores ngenxa yokufudumeza.

Amanyathelo ahambelanayo: i-welding phambi kwe-nitriding; Gcoba umaleko we-nitride.

Isizathu sesi-3 : Kukho ukungcola kwi-welding surface kwaye intonga ye-welding ayisomisiwe njengoko ifunwa, okubangela ukuveliswa kwegesi ngexesha lokunyibilika.

Amanyathelo ahambelanayo: Ngaphambi kwe-welding, i-grease, i-coating, i-lubricant yokucubungula kunye nefilimu ye-oxide ebusweni be-weldment kufuneka isuswe; iintonga ze-welding kufuneka zomiswe njengoko zifunwa.

4. Ukunciphisa ubulukhuni kunye nokuhlanjululwa kwendawo

Isizathu: Ukutshintsha kweqondo lokushisa ngexesha le-welding kubangela unyango olushushu kwiindawo, okubangelwa utshintsho kwizinto eziphathekayo zamalungu.

Amanyathelo ahambelanayo: Landela inkqubo ye-welding enikezelwa ngumthengisi wentsimbi.

5. Amanye amacebiso

Ulwazi olusisiseko lwensimbi yonyango yokushisa: 1. Xa isinyithi siphantsi konyango lokushisa njenge-nitriding okanye i-welding ye-preheating ye-welding jikelele, qaphela ukuba ukushisa akufuneki kudlule ubushushu bokushisa kwentsimbi ngaphambi kokushiya i-factory, ngaphandle koko ukuqina kwentsimbi kuya kuncitshiswa kwaye i-deformation yamacandelo iya kubangelwa.

P20 preheating ngokubanzi ecetyiswayo inkqubo yonyango ubushushu ngokubanzi: preheat ukuya degrees 350-450 kwaye ke weld, umsindo malunga 550 degrees (ukuwelda imingundo ebalulekileyo, inkqubo yonyango ubushushu kufuneka ilawulwe ngokungqongqo ngokweengcebiso zomenzi).

Ukuze kuthintelwe imingxuma yesanti ephindaphindiweyo ngexesha lokupolisha emva kwe-welding, i-welding flaw detector ingasetyenziselwa ukujonga kuqala emva kwe-welding. Iindawo eziyingxaki zinokugrunjwa zize zidityaniswe ukunqanda imingxuma yesanti ephindaphindiweyo.

I-Welding yobhedu lwe-beryllium: Ubhedu lwe-beryllium luchaphazeleka ngakumbi kwi-oxidation. Kufuneka ifakwe ngokukhawuleza emva kokuba ifilimu ye-oxide isuswe ngebrashi ebukhali okanye i-sandblasting. Ubunzima bendawo edibeneyo kunye neendawo ezijikelezileyo ziya kuncipha. Ukuba ukuhla kobunzima akuvumelekanga, unyango lokufudumeza kwakhona luyafuneka.
