5 Laser Welding Quality Problems & Solutions

Izinkinga Nezixazululo Ezinhlanu Zekhwalithi Yokushisela Nge-Laser

Hlangana nesimo esihlukile somshini wokushisela we-laser

Ngokusebenza kahle kakhulu, ukunemba okuphezulu, umphumela omuhle wokushisela, ukuhlanganiswa okulula okuzenzakalelayo, kanye nezinye izinzuzo, ukushisela nge-laser kusetshenziswa kabanzi ezimbonini ezahlukahlukene futhi kudlala indima ebalulekile ekushiseleni insimbi ekukhiqizweni nasekukhiqizeni, okuhlanganisa ezempi, ezokwelapha, ezindizayo, izingxenye zezimoto ze-3C, insimbi yeshidi lomshini, amandla amasha, ihadiwe yenhlanzeko, kanye neminye imboni.

Kodwa-ke, noma iyiphi indlela yokushisela uma ingakaqedi kahle isimiso sayo kanye nobuchwepheshe, izokhiqiza amaphutha athile noma imikhiqizo enephutha, ukushisela nge-laser akuhlukile. Ukuqonda okuhle kwala maphutha kuphela, nokufunda ukuthi ungawagwema kanjani la maphutha, ukudlala kangcono ukubaluleka kokushisela nge-laser, ukucubungula ukubukeka okuhle, kanye nemikhiqizo yekhwalithi enhle. Onjiniyela ngokuqongelela ulwazi lwesikhathi eside, bafingqa amanye amaphutha avamile okushisela esisombululo, ukuze kubhekwe ozakwabo embonini!

1. Imifantu

Imifantu ekhiqizwa ekushiseni okuqhubekayo nge-laser ikakhulukazi imifantu eshisayo, njengemifantu ye-crystallization, imifantu encibilikisiwe, njll. Isizathu esiyinhloko ukuthi i-weld ikhiqiza amandla amakhulu okuncipha ngaphambi kokuqina okuphelele. Ukusebenzisa i-wire feeder ukugcwalisa izintambo noma ukushisa kusengaphambili ingxenye yensimbi kunganciphisa noma kuqede imifantu eboniswe ngesikhathi sokushiseni nge-laser.

2. Imigodi ekushiseni

I-Porosity iyiphutha elilula ekushiseni nge-laser. Ngokuvamile ichibi lokushiseni nge-laser lijulile futhi lincane, futhi izinsimbi zivame ukuhambisa ukushisa kahle kakhulu futhi ngokushesha okukhulu. Igesi ekhiqizwa echibini elincibilikisiwe eliwuketshezi ayinaso isikhathi esanele sokuphuma ngaphambi kokuba insimbi yokushiseni iphole. Icala elinjalo kulula ukuholela ekwakhekeni kwama-pores. Kodwa futhi ngenxa yokuthi indawo yokushisa yokushiseni nge-laser incane, insimbi ingaphola ngokushesha kakhulu, ama-porosity avelayo aboniswa ekushiseni nge-laser ngokuvamile mancane kune-fusion welding yendabuko. Ukuhlanza indawo yokusebenza ngaphambi kokushiseni kunganciphisa ukuthambekela kwama-pores, futhi indlela yokufutha izothinta nokwakheka kwama-pores.

3. Ukuchaphaza

Uma ushisela insimbi ngokushesha kakhulu, insimbi ewuketshezi ngemuva kwembobo ekhomba enkabeni ye-weld ayinaso isikhathi sokusabalalisa kabusha. Ukuqina kuzo zombili izinhlangothi ze-weld kuzokwakha ukuluma. Uma igebe phakathi kwezingcezu ezimbili zomsebenzi likhulu kakhulu, ngeke kube nensimbi encibilikisiwe eyanele etholakalayo yokubopha, lapho-ke ukushisela umphetho kuzokwenzeka futhi. Esigabeni sokugcina sokushisela nge-laser, uma amandla ehla ngokushesha kakhulu, imbobo kulula ukuyidiliza futhi kuholele ezifweni ezifanayo zokushisela. Amandla okulinganisela angcono kanye nesivinini sokuhamba kwezilungiselelo zokushisela nge-laser kungaxazulula ukukhiqizwa kokushisela umphetho.

4. Ukunqunywa okungaphansi

Ukuchaphaza okwenziwa yi-laser welding kuthinta kakhulu ikhwalithi yobuso be-weld futhi kungangcolisa futhi kulimaze ilensi. Ukuchaphaza kuhlobene ngqo nobuningi bamandla, futhi kungancishiswa ngokunciphisa kahle amandla e-welding. Uma ukungena kunganele, isivinini se-welding singancishiswa.

5. Ukuwa kwechibi elincibilikisiwe

Uma ijubane lokushisela lihamba kancane, ichibi elincibilikisiwe likhulu futhi libanzi, inani lensimbi encibilikisiwe liyakhula, futhi ukucindezeleka kobuso kunzima ukulondoloza insimbi esindayo ewuketshezi, isikhungo sokushisela sizocwila, sakhe ukugoba kanye nemigodi. Ngalesi sikhathi, kubalulekile ukunciphisa ubuningi bamandla ngendlela efanele ukuze kugwenywe ukugoba kwechibi elincibilikisiwe.
