You doing welding in ATM temp , that mean NORMALIZING process.
Case 1
If heat input rate is High with constant speed HAZ is High
Compare to lower heat input rate
Case 2
If heat input rate is constant but speed of welding is less then optimum speed of this heat input rateΒ HAZ is High
These conditions only HAZ can developed drastically
So it’s not depend upon welding process , it’s depends only size of weld bead , and skilled labour

There are two reasons behind for higher HAZ
Heat input rate
Speed of welding

Cohesive force is stronger , when cohesive force is low then adhesive force dominate
