Mofuta oa lithupa tsa brazing o sebelisitsoeng o itšetlehile ka ts'ebeliso e khethehileng le lisebelisoa tse kopantsoeng. Mefuta e meng e tloaelehileng ea li-brazing rods e kenyelletsa:

1. Lithupa Tsa Brass Brazing: Lithupa tsena li entsoe ka motsoako oa koporo-zinc 'me hangata li sebelisetsoa ho kopanya thepa ea koporo, ea koporo le ea boronse.

2. Boronse Brazing Rods: Lithupa tsa boronse li entsoe ka lialloi tsa koporo-tin 'me hangata li sebelisetsoa ho kopanya tšepe, tšepe e entsoeng ka tšepe le litšepe tse ling tse entsoeng ka tšepe.

3. Silver Brazing Rods: Li-Silver rod li na le peresente e ngata ea silevera 'me li sebelisetsoa ho kopanya mefuta e mengata ea tšepe, ho akarelletsa le koporo, brass, stainless steel, le li-alloys tsa nickel. Li fana ka manonyeletso a matla le a ka tšeptjoang.

4. Aluminium Brazing Rods: Lithupa tsena li etselitsoe ho kopanya aluminium le lialloys tsa aluminium. Hangata li na le silicon e le karolo ea mantlha ea alloying.

5. Li-Flux-coated Brazing Rods: Li-brazing rods tse ling li tla le "flux coating", e thusang ho tlosa li-oxide le ho ntlafatsa ho phalla ha tšepe ea ho tlatsa nakong ea ho betla. Lithupa tse koahetsoeng ka Flux hangata li sebelisetsoa ho betla lisebelisoa tsa koporo, koporo le boronse.

Li-cutters tsa PDC li khabisitsoe ho 'mele oa tšepe kapa oa matrix oa PDC drill bit. Ho ea ka mokhoa oa ho futhumatsa, mokhoa oa ho roala o ka aroloa ka ho chesa mollo, ho qhibiliha ha vacuum, vacuum diffusion bonding, high-frequency induction brazing, laser beam welding, joalo-joalo The Flame brazing e bonolo ho sebetsa le ho sebelisoa haholo.

Ha u khabisa li-cutters tsa PDC, ke habohlokoa ho sebelisa molamu oa brazing o nang le ntlha e qhibilihisang ka tlaase ho thepa ea PDC cutter ho thibela tšenyo ea sehahi. Ts'ebetso ea brazing e kenyelletsa ho futhumatsa molamu oa brazing le kopano ea PDC cutter ho mocheso o itseng, ho lumella alloy brazing ho qhibiliha le ho phalla pakeng tsa sehahi le substrate, ho theha maqhama a matla.Ka kakaretso, li-alloys tsa silver brazing li sebelisoa hangata bakeng sa PDC cutter welding, hangata li entsoe ka silevera, koporo, le likarolo tse ling ho fihlela lintho tse lakatsehang. Li-alloys tsena li na le silevera e ngata, boemo bo tlase ba ho qhibiliha le mekhoa e metle ea ho koloba. Boleng ba silevera bo phahameng bo netefatsa ho koloba ho hotle le maqhama pakeng tsa PDC cutter le drill bit body material.

Ho na le lithupa tsa tšepe tsa silevera le poleiti ea brazing ea silevera, tse ka sebelisoang ka bobeli bakeng sa li-cutters tsa PDC. Ha e le hantle, lithupa tsa tšepe tsa silevera tse nang le silevera ea 45% ho isa ho 50% li loketse PDC cutter welding. Kereiti e khothaletsoang ea li-silver brazing rods le poleiti ke sehlopha sa Bag612, se nang le 50% ea silevera.
