Very likely to leak,
zinc in the GI pipe will be contaiminating the weld and thus you cannot get a good weld.
Grind the surface of GI pipe lightly to remove the skin which is about 0.1 to 0.2 mm, than weld the MS pipe as per the wall thickness and use accordingly the welding rod at the required gauge / Dia of the welding rod. this works fine.
1 '' gi b class pipe weight of per mtr

Threading joint, weld joint, Flanges joint
there is difference in material ms is mild steel and gi is galvanised iron, hence the properties will be different

Gi weld not recommended . Because of gi coationg will be spoiled out . Puncture will be occur on the pipe weld .
A GI pipe is welded to a GI pipe by using solder and flux. The pipe is heated up, flux applied, and then solder allowed to flow into the joints to create a secure bond.
GI Pipe is "Galvanized Iron" Pipe. These days the pipe will likely be made from steel rather than iron.
Galvanized Iron pipe
A weldolet is a fitting you weld on a (run) pipe, and then butt weld a branch pipe to it. A tredolet is a fitting you weld on a (run) pipe, and then screw a threaded branch pipe to it. Some people call this a threadolet A sockolet is a fitting you weld on a (run) pipe, and then socket weld a branch pipe to it. A nipolet is the same as a weldolet or thredolet but has an elongated branch connection. You have to specify if it's a welded or threaded nipolet.
The pipe must be fixed (not rolled) in the horizontal position. With the pipe horizontal, the weld is vertical. The pipe being fixed requires the welder to weld flat (top), vertical (sides), and overhead (bottom). The pipe must be fixed (not rolled) in the horizontal position.

which class gi pipe is better
wildly welding main pipe the are fillet weld or butweld
Gi pipe is climate dependent. Someone who lives on the coast with Gi pipe will find that their pipes will deteriorate quicker than someone who lives more inland because of the higher salt content in the air, the Gi pipe rusts. Also burying Gi in the sand or installing the Gi pipe in concrete also doesnt allow the pipe to breath.
A butt weld is where the diameter of the pipes welded together are the same, a socket weld is where a larger diameter pipe is fitted into a smaller one. In making a butt weld, the pipes (or pipe and fitting) usually have an angle machined or ground into the outside corner, so when they are placed together face-face, there is a circumferential V shaped gap serving as the weld prep. In a socket weld, the pipe is inserted into the socket, backed off slightly to make a gap between the end of the pipe and the bottom of the socket, and the weld is made around the outside diameter of the socket to the outside diameter of the pipe. The gap at the bottom of the pipe prevents thermal expansion from stressing the joint during or after welding.
