Indlela yokudibanisa i-titanium, iiWelders, nceda ugcine eli nqaku

I-alloys ye-Titanium inoxinano oluphantsi, amandla athile aphezulu, ukuxhathisa okulungileyo kwe-corrosion, ukuhanjiswa kwe-thermal ephantsi, i-non-toxic kunye ne-non-magnetic, kwaye inokudityaniswa; zisetyenziswa kakhulu kwi-aviation, i-aerospace, ikhemikhali, i-petroleum, umbane, unyango, ukwakhiwa, iimpahla zemidlalo kunye nezinye iindawo.

Iindlela eziqhelekileyo zokudibanisa i-titanium kunye ne-titanium alloys ziquka: i-argon arc welding, i-arc welding ephantsi kwamanzi, i-vacuum electron beam welding, njl.

Ukulungiselela phambi kwe-welding

Umgangatho ongaphezulu we-weldment kunye ne-titanium welding wire inempembelelo enkulu kwiipropati zomatshini we-welded joint, ngoko kufuneka ihlambuluke ngokungqongqo.

1) Ukucoca ngoomatshini: Kwimidiza engafuni umgangatho ophezulu we-welding okanye kunzima ukuyicoca, i-sandpaper entle okanye iibhrashi zocingo ezingenastainless zingasetyenziselwa ukuzosula, kodwa kungcono ukusebenzisa i-carbide yellow ukukrwela ipleyiti ye-titanium ukususa icwecwe. ifilimu oxide.

I-2) Ukucocwa kweekhemikhali: Ngaphambi kwe-welding, isiqwenga sovavanyo kunye nocingo lwe-welding lunokukhethwa. Isisombululo se-pickling sinokuba yi-HF (5%) + i-HNO3 (35%) isisombululo samanzi. Hlamba ngamanzi acocekileyo emva kokukha, kwaye weld ngokukhawuleza emva kokumisa. Okanye sebenzisa i-acetone, i-ethanol, i-carbon tetrachloride, i-methanol, njl njl ukusula i-titanium plate groove kunye namacala omabini (ngaphakathi kwe-50mm ngalinye), umphezulu we-wire welding, kunye nenxalenye apho i-fixture idibanisa ipleyiti ye-titanium.

3) Ukukhethwa kwezixhobo zokuwelda: Kwi-argon arc welding ye-titanium kunye ne-titanium alloy tungsten iipleyiti, umthombo wamandla we-DC argon arc welding eneempawu zangaphandle kunye nokuqaliswa kwe-arc ephezulu-frequency kufuneka kukhethwe, kwaye ixesha lokulibaziseka kwegesi kufuneka libe ngaphantsi kwe Imizuzwana ye-15 ukuphepha i-oxidation kunye nokungcoliswa kwe-weldment.

I-4) Ukukhethwa kwezixhobo ze-welding: Ukucoceka kwegesi ye-argon akufanele kube ngaphantsi kwe-99.99%, indawo yombethe kufuneka ibe ngaphantsi kwe-40 ℃, kunye neqhekeza elipheleleyo lokungcola kufuneka libe yi-0.001%. Xa uxinzelelo kwi-argon cylinder yehla ukuya kwi-0.981MPa, kufuneka imiswe ukuthintela ukuchaphazela umgangatho we-welded joint.

Izixhobo zokuwelda iXinfa zineempawu zomgangatho ophezulu kunye nexabiso eliphantsi. Ngeenkcukacha, nceda undwendwele:Abavelisi beWelding & Cutting-China Welding & Cutting Factory & Suppliers (xinfatools.com)

I-5) Ukukhuselwa kwegesi kunye nokushisa kwe-welding: Umbhobho we-titanium odibeneyo uphantsi ngexesha le-welding. Ukuze kuthintelwe umdibaniso odityanisiweyo ukuba ungangcoliswa ziigesi eziyingozi kunye nezinto kumaqondo obushushu aphezulu, indawo yokuwelda kunye ne-weld kufuneka ixhomekeke kukhuseleko oluyimfuneko kunye nolawulo lobushushu, kwaye ubushushu kufuneka bube ngaphantsi kwe-250℃.
