Nkwadebe tupu ịgbado ọkụ
Ọdịdị elu nke welding na titanium welding waya nwere mmetụta dị ukwuu na ihe eji arụ ọrụ nke nkwonkwo welded, n'ihi ya, a ghaghị ihicha ya nke ọma.
1) Mechanical ihicha: Maka welds nke na-adịghị achọ akwa ịgbado ọkụ ma ọ bụ siri ike pickling, ezi sandpaper ma ọ bụ igwe anaghị agba nchara waya brushes nwere ike iji hichaa ha, ma ọ kasị mma na-eji carbide odo na-ehichapụ efere titanium iji wepụ ihe ndị ahụ. ihe nkiri oxide.
2) Chemical nhicha: Tupu ịgbado ọkụ, na ule ibe na ịgbado ọkụ waya nwere ike pickled. Ngwọta pickling nwere ike ịbụ HF (5%) + HNO3 (35%) ngwọta mmiri. Wepu mmiri dị ọcha mgbe ịchachara, wee weld ozugbo ihichachara. Ma ọ bụ jiri acetone, ethanol, carbon tetrachloride, methanol, wdg na-ehichapụ oghere titanium efere na n'akụkụ abụọ (n'ime 50mm nke ọ bụla), elu nke waya ịgbado ọkụ, na akụkụ ebe nkwụnye ahụ na-akpọtụrụ efere titanium.
3) Nhọrọ nke ngwa ịgbado ọkụ: Maka argon arc ịgbado ọkụ nke titanium na titanium alloy tungsten plates, a DC argon arc welding ike isi iyi nwere njirimara mpụga na mmalite arc ugboro dị elu kwesịrị ịhọrọ, na oge nnyefe gas na-egbu oge kwesịrị ịbụ ihe na-erughị ala. 15 sekọnd iji zere oxidation na mmetọ nke weldment.
4) Nhọrọ nke ịgbado ọkụ ihe: The ịdị ọcha nke argon gas kwesịrị ịbụ ihe na-erughị 99.99%, igirigi ebe kwesịrị n'okpuru -40 ℃, na ngụkọta uka akụkụ nke adịghị kwesịrị 0,001%. Mgbe nrụgide dị na argon cylinder na-adaba na 0.981MPa, ekwesịrị ịkwụsị ya ka ọ ghara imetụta àgwà nke nkwonkwo welded.
