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 weld not recommended . Because of gi coationg will be spoiled out . Puncture will be occur on the pipe weld .
Very likely to leak, zinc in the GI pipe will be contaiminating the weld and thus you cannot get a good weld.
there is difference in material ms is mild steel and gi is galvanised iron, hence the properties will be different
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.
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.
which class gi pipe is better
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.
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.

GI Pipe is "Galvanized Iron" Pipe. These days the pipe will likely be made from steel rather than iron.
