Mathata le Lisosa tsa Lisebelisoa tsa ho Seha Carbide

undefined


Lisebelisoa tsa ho itšeha tsa Tungsten carbide hangata li na le mathata a ho qhekella ka mor'a ho betla. Ka tlase ke a mang a mathata a braze le lisosa tsa ona.

1. Tungsten carbide tip fractures le mapetsong

Mabaka a ka sehloohong a ho robeha le mapetsong a brazing ke a latelang:

A: Lehlakore la sebaka se mahlahahlaha pakeng tsa karolo e ka tlaase ea hlooho ea sehahi le setsi sa hlooho ea sehahi ha sea nepahala 'me sebaka sa brazing se nyane haholo, kahoo thepa ea welding le flux e ke ke ea ajoa ka ho feletseng.

B:  Litšepe tsa solder tse sa lumellaneng li khutšoanyane haholo ha li bapisoa le sefahleho sa braze, e leng se etsang hore ho be le kamano e tobileng pakeng tsa karolo e ka tlaase ea carbide le tšepe ea motheo, 'me lisebelisoa tsa braze li ajoa har'a tsona.

C: Linako tsa ho futhumatsa le ho pholisa li potlakile haholo kapa li lieha haholo

D: Thempereichara ea soldering e phahame haholo. Kaha coefficient ea katoloso ea linear ea carbide e entsoeng ka samente e tlase haholo, haeba mocheso o phahame haholo, khatello e kholo ea mocheso e tla hlahisoa ka har'a lenonyeletso, e fetang matla a thata a carbide e entsoeng ka samente, e tla lebisa ho phatloheng ha carbide e entsoeng ka samente.

2. Braze porosity

Mabaka a ka sehloohong a bothata bona ba brazing ka li-pores ke:

A: Haeba mocheso oa solder o le holimo haholo, o tla etsa hore zinc e phophole ka har'a thepa ea tabo ea solder

B: Haeba mocheso oa soldering o le tlase haholo, phallo e ke ke ea qhibiliha ka ho feletseng, e bakang ho phophoma.

3. Ntlheng ea carbide e oa

Mathata a ka sehloohong a carbide tip a oa ke hobane:

A: Khetho ea thepa ea solder e fosahetse, e ke ke ea kolobisoa ka tšepe ea motheo, kapa sebaka se kolobisitsoeng se nyane haholo.

B: Mocheso oa mocheso o tlase haholo, 'me solder ha e kenelle ka ho feletseng, e leng se bakang ho fokotseha ha matla a braze le hlooho ea cutter e oa.

C: Thepa ea solder e nyane haholo, 'me matla a fokotsehile

D: Thempereichara e phahame haholo, 'me karolo ea solder ea phalla

E: Thepa ea solder ha e tsepame, e bakang kabo e sa lekanang ea solder, e etsa karolo ea brazing seam ea bohata, le matla a sa lekaneng a ho tiisa.


Haeba u thahasella lisebelisoa tsa ho seha li-tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka RE THUTA ka mohala kapa ka poso ka ho le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.

RE THUSOE MOSE
Ka kopo, romella molaetsa 'me re tla khutlela ho uena!
