C. arc welding
D. inert gas arc welding
The nature of submerged arc welding flux with basicity index of 0.5 is
A. neutral
B. basic
C. semi-basic
D. acidic

For a good quality brazing, the molten filler alloy should have
A. low contact angle with the base metal
B. low density
C. high surface tension
D. high viscosity
Lap joint provides larger surface area for filler material bonding significantly increasing strength compared to butt so the provide stronger shear and tension the correct answer should be option c.
