Isingeniso
Ekushiseleni amathebhu ebhethri ezimoto zamandla amasha, ukusetshenziswa kwe-hemispherical projections kucapacitive discharge spot welderamasistimu akhulise amandla ahlangene ngo-40%. Ngaleso sikhathi, umkhiqizi wezokuvikela uthole i-ziro{2}}i-spatter welding yezingxenye ezacile{3}}ze-titanium yasodongeni esebenzisa ukuqagela okumise okukhethekile. Lezi zimpumelelo zibonisa ukuthi i-projection geometry ingaphezu kwesici esilula somklamo{5}}ihlanganisa ukulawulwa kwenkambu yamanje, ibhalansi ye-thermodynamic, kanye ne-rheology yezinto ezibonakalayo. Njengento eyinhloko enquma ikhwalithi yokushisela, umumo wokuqagela uthonya ngokuqondile ukugxila kwamandla (okudlula ama-92%) kanye nokuzinza kwe-nugget. Lesi sihloko sihlinzeka ngokuhlaziywa okuhlelekile kwezinhlobo ezine ezinkulu zokuqagela kanye nezicelo zazo zezimboni kucapacitive discharge spot welderubuchwepheshe.
1. Izimiso Eziyisisekelo: Ukuma Kwe-Projection Kuthinta Kanjani Ikhwalithi Ye-Weld
Ukuqagela kucapacitive discharge spot welderamasistimu anika amandla ukukhululwa kwamandla okuqondisa. Umklamo wabo kufanele ufeze izinhloso ezintathu:
- Ukulawulwa Kwamanje Kokuminyana: Lungiselela ukusatshalaliswa futhi ugweme imiphumela enqenqemeni (iphutha<±5%).
- Umthetho Wokufaka Kokushisa: Bhalansa ukwakheka kwe-nugget nokushisa-indawo ethintekile (HAZ).
- Ukuphumelela Kokuqhuba Ingcindezi: Qinisekisa ukudluliswa kwamandla afanayo (ukuguquguquka<±3%).

- I-Composite Projection Design:
I-Tungsten-i-copper base ene-diamond coating (50μm) imelana no-800 degree, ivumela u-800,{4}} ishise ngensimbi{5}}yamandla aphezulu.
Isiphetho
Umkhiqizi webhethri elinamandla oholayo wehlise i-spatter ukusuka ku-0.5% ukuya ku-0.02% esebenzisa ukuqagela okukhethekile-konga ngaphezu kwezigidi ezingu-¥5 ngonyaka ezindlekweni ezibonakalayo. Ibhizinisi le-aerospace lizuze ukushiselwa okuthembekile kwe-titanium foil engu-0.15mm, okube nesandla ekwehlisweni kwesisindo sesathelayithi ngo-15%. Le miphumela iqinisekisa ukuthi ukunemba kokuqagela ukuklama kungakhuphulacapacitive discharge spot welderukusebenza ezindaweni eziphakeme ezintsha. Ngokuhlanganiswa kokuthuthukiswa kwe-topological kanye nokukhiqiza okungeziwe, ukuqagela okuzayo kuzofaka ukuwohloka okuguquguqukayo, ama-microstructures alawulekayo, nama-gradients asebenzayo{1}}okuvula amandla amakhulu nakakhulu okukhiqiza okuthuthukile.
