Welding processingndi wamba zitsulo njira kuti angagwiritsidwe ntchito kujowina mitundu yosiyanasiyana ya zitsulo zipangizo. Posankha zinthu zomwe zimatha kuwotcherera, zinthu monga momwe zinthuzo zimapangidwira, malo osungunuka, komanso momwe matenthedwe amatenthetsera ziyenera kuganiziridwa. Zida wamba zomwe zimatha kuwotcherera ndi chitsulo cha kaboni, chitsulo chosapanga dzimbiri, chitsulo chosapanga dzimbiri, aluminiyamu ndi mkuwa.

Mpweya wa carbon ndi chinthu chowotcherera wamba chokhala ndi weldability wabwino komanso mphamvu, ndikupangitsa kuti ikhale yoyenera ntchito zambiri zamafakitale. Chitsulo chopangidwa ndi galvanized nthawi zambiri chimagwiritsidwa ntchito pofuna kuteteza dzimbiri ndipo kutsekemera kwake kumadalira makulidwe ndi mtundu wa zosanjikizazo. Chitsulo chosapanga dzimbiri chimakhala ndi kukana kwa dzimbiri ndipo ndichoyenera malo omwe amafunikira kukana kwa dzimbiri, koma kuwotcherera chitsulo chosapanga dzimbiri kumafunikira mwapadera.kuwotcherera njirandi zipangizo. Aluminiyamu ndi chitsulo chopepuka chokhala ndi matenthedwe abwino komanso magetsi, koma kuwotcherera aluminium kumafuna njira zapadera zowotcherera ndi zida za aloyi. Mkuwa uli ndi mphamvu yabwino yamagetsi ndi matenthedwe ndipo ndi yoyenera kusinthanitsa magetsi ndi kutentha, koma kuwotcherera mkuwa kumafuna kuganizira za okosijeni.

Posankha zida zowotcherera, mawonekedwe azinthu, malo ogwiritsira ntchito ndi njira zowotcherera ziyenera kuganiziridwa kuti zitsimikizire mtundu ndi magwiridwe antchito a kulumikizana kowotcherera. Kuwotcherera ndi njira yovuta yomwe imafuna kulingalira mozama za kusankha kwa zinthu, njira zowotcherera ndi njira zogwirira ntchito kuti zitsimikizire ubwino ndi kudalirika kwa mgwirizano womaliza.
