b. A na-etinye ihe ụfọdụ Alloya iji belata klọọkụ na oghere. Dịka ọmụmaatụ, aluminium na ígwè nwere ike ịfụ mkpụrụ ọka.
c. The weld with shallow penetration shall be used to improve the heat dissipation condition so that the low melting point material floats on the weld surface and does not exist in the weld.
d. A ga-anabata nkọwapụta nke ọma, a ga-anabata nkọwapụta ya, a ga-anabatakwa preheting na mgbe a ga-anakwere ikpo ọkụ.
e. Adopt reasonable assembly sequence to reduce welding stress.

Ihe iji gbochie cracks chacks:
a. Pay attention to the strengthening effect of metallurgical elements and their influence on reheat cracks.
b. Reasonably preheat or use afterheat to control the cooling rate.
c. Belata nrụgide dị iche iche iji zere itinye uche na nche.
