Qwalasela iipropathi ezibonakalayo, iipropathi zoomatshini kunye nokwakheka kweekhemikhali zezinto ze-weld
1. I-welding yensimbi yolwakhiwo, ngokuqhelekileyo iqwalasela umgaqo wamandla alinganayo, khetha ukuhlangabezana neemfuno zeempawu zomatshini we-joint welding material.
2. Kwintsimbi ye-carbon ephantsi kunye nentsimbi ephantsi ye-alloy ephakathi kwe-welding joint of steel dissimilar, ngokuqhelekileyo khetha izinto ezisetyenziswayo ze-welding ezihambelanayo kunye nebakala eliphantsi lamandla ensimbi.
3. Kuba intsimbi ukumelana nobushushu kunye welding steel stainless, ngaphezu kokuqwalasela amandla, kodwa kwakhona qwalasela ukwakheka imichiza engundoqo weld metal kunye nokwakheka imichiza izinto umzali vala.
4. Xa ukwakheka kwemichiza yezinto zomzali, ezifana nekhabhoni okanye isulfure, iphosphorus kunye nezinye izinto ezinobungozi ziphezulu, kufuneka zikhethe izinto ezisetyenziswayo zokuwelding ezinamandla.Okufana ne-hydrogen ephantsi yohlobo lwe-welding consumables.
Cinga ngeemeko zokusebenza ze-welding kunye nokusetyenziswa kokusebenza
1. Amacandelo adibeneyo kwimeko yomthwalo oguquguqukayo kunye nomthwalo wempembelelo, ngaphezu kweemfuno zokuqinisekisa amandla okuqina, amandla okuvelisa, ukuqina kwempembelelo, iplastiki yimfuno ephezulu.Ngeli xesha kufuneka kukhethwe kunye ne-low-hydrogen welding material.
2. Amalungu adityanisiweyo kwimidiya ephazamisayo, kufuneka ahluke kuhlobo lweendaba, ukugxininiswa, ubushushu bokusebenza kunye nohlobo lwe-corrosion (i-corrosion jikelele, i-intergranular corrosion, i-corrosion yoxinzelelo, njl.), ukwenzela ukuba ukhethe izinto ezifanelekileyo ze-welding steel stainless.
3. Xa i-weld isebenza phantsi kweemeko zokunxiba, kuyimfuneko ukwahlula phakathi kokunxitywa ngokubanzi okanye ukunxitywa kwempembelelo, ukunxiba kwe-intermetallic okanye ukunxitywa kwe-abrasive, ukunxiba kwiqondo lokushisa okanye ukunxiba kwiqondo lokushisa eliphezulu, njl. njl. , ukuze ukhethe i-welding efanelekileyo yokugqithisa i-welding consumables.
4. Kwiqondo lokushisa eliphantsi okanye i-welding ye-welding parts, kufuneka ukhethe ukuqinisekisa ukuba ukushisa okuphantsi okanye ubushushu obuphezulu beempawu zemishini ye-welding material.
Cinga ubunzima kunye neempawu zesakhiwo seendawo ezidibeneyo, uhlobo oludibeneyo oludibeneyo, njl.
1. Ubume obuyinkimbinkimbi okanye ubukhulu obukhulu beendawo ezidibeneyo, ngenxa yentsimbi ye-welding yayo kwi-contraction yokupholisa yoxinzelelo lwangaphakathi oluveliswa ngubukhulu, kulula ukuvelisa iintanda.Ke ngoko, kuyafuneka ukuba kusetyenziswe izinto ezityiwayo ze-welding ezinokumelana nokuqhekeka okulungileyo, njenge-low-hydrogen ye-welding rod, intonga ye-welding ephezulu.
2. Kumalungu athile anama-bevels amancinci, okanye amalunga anolawulo olungqongqo lokungena kweengcambu, i-welding consumables kunye nobunzulu obukhulu bokudibanisa okanye ukungena kufuneka kusetyenziswe.
3. Ngenxa yokunyanzeliswa kweminye imimandla ye-welding enzima ukuyicoca, kufuneka ithathelwe ingqalelo ukusetyenziswa kwe-rust, i-oxidation kunye ne-oyile yokusabela ayikhathaleli kwizinto ze-welding, ezifana ne-acid welding rod, ukwenzela ukuba ingavelisi iziphene ezifana ne-porosity.
Qwalasela indawo ye-weld
Ezinye izinto ezisetyenziselwa ukuwelda zifanelekile kuphela ukuwelda kwindawo ethile, ezinye izikhundla zingasebenzi kakuhle xa zidibanisa, ezinye izinto ezisetyenziselwa ukuwelda ziyakwazi ukuthungatha kwiindawo ezahlukeneyo, iimpawu zesithuba se-welding kufuneka ziqwalaselwe xa ukhetha.
Cinga ngeemeko zokusebenza ze-welding, indawo yokusebenza
1. Akukho zihlandlo zomatshini we-DC welding, kufuneka zisebenzise i-AC kunye ne-DC ezimbini-ukusetyenziswa kwezinto zokuwelda.
2. Ezinye intsimbi (ezifana nentsimbi pearlite ubushushu-resistant) kufuneka ibe post-weld isiqabu unyango ubushushu, kodwa iimeko izixhobo okanye imiqobo yayo yesakhiwo kwaye ayikwazi kuqhutywa, kufuneka zikhethwe kunye nesiseko metal imichiza ezahlukeneyo welding consumables (ezifana austenitic stainless steel stainless welding consumables), inokukhululwa kwi-post-weld heat heat.
3. Kufuneka isekelwe kwiimeko zendawo yokwakha, ezifana nokusebenza kwentsimi, indawo yokusebenza ye-welding, njl.
4. Kwiindawo apho zombini i-electrodes ye-asidi kunye ne-alkaline welding ingasetyenziswa, i-electrodes ye-welding ene-acidic kufuneka isetyenziswe kangangoko kunokwenzeka ngenxa yeemfuno eziphezulu ze-alkaline welding electrode kubuchule bokusebenza kunye nokulungiswa kokwakhiwa.
Qwalasela uqoqosho lokuwelda
1. Zama ukusebenzisa i-welding consumables engabizi kakhulu, ngaphandle kokuba ukusebenza kokusetyenziswa kuqinisekisiwe.
2. I-welding consumables eyahlukeneyo ingasetyenziselwa i-welds yeprayimari kunye neyesibini kunye neemfuno ezahlukeneyo zokusebenza, kwaye ungaqhubeki ukusebenza ngokupheleleyo kwezinto ezisetyenziswayo ze-welding unilaterally.
Qwalasela ukusebenza kakuhle kwe-welding
Kwizakhiwo ezinomsebenzi omkhulu we-welding, ukusetyenziswa kwe-welding ephezulu kufuneka kusetyenziswe kangangoko kunokwenzeka xa kukho, njengocingo lwe-welding, intonga ye-iron powder welding, i-stainless steel stainless welding stick, njl njl.
