root pass
between 30 and 40 degrees preferably 37 like pipe
A bevel weld is a type of joint used in welding where the edges of the base materials are shaped at an angle, typically between 30 to 45 degrees, to facilitate better penetration and bonding during the welding process. This configuration is particularly useful for thick materials, as it allows for a deeper weld pool and ensures a stronger joint. Bevel welding is commonly employed in applications such as structural steel fabrication and pipe welding. It enhances the overall strength and integrity of the welded joint by providing a larger surface area for the weld metal.
The first weld made when welding pipes with beveled edges is called the "root pass." This initial weld is crucial as it establishes the foundation for the joint, ensuring proper penetration and fusion between the two pipe edges. The root pass is typically performed with a smaller electrode and lower heat settings to control the weld pool and prevent burn-through. Subsequent passes, known as fill and cap passes, are added to complete the joint.

The first weld made when joining two pipes with beveled edges is called the "root pass." This initial weld establishes a foundational joint at the root of the bevel, ensuring proper penetration and alignment of the joint before subsequent layers or passes are added. It is crucial for the strength and integrity of the overall weld.
It is the first pass in a multiple weld joint.

The angle of the bevel for a butt weld typically ranges from 30 to 37.5 degrees, depending on the thickness of the materials being welded and the specific welding code or standard being followed. A common bevel angle is 45 degrees, as it allows for good penetration and fusion of the weld metal. The bevel design helps ensure a strong joint and is influenced by factors such as the welding process and the type of materials involved.
You always weld the side with the preperation first, then if you get incomplete penetration you can grind the back out
27.5 degrees
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.

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.
