What is bevel weld?
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.
Butt-weld and grrove weld?
Butt weld and groove weld are two common types of weld joints used in welding processes. A butt weld is a type of weld where two pieces of metal are joined together along their edges in a single plane, creating a smooth, flush surface. On the other hand, a groove weld is a type of weld where a groove or channel is created in one or both of the pieces being joined, and the filler material is deposited into the groove to create the weld. Both types of weld joints are used in various applications depending on the specific requirements of the project.
What is peening in welding?
It is one way to "Stress Relieve" the weld joint. As the weld metal metal cools it contracts and hammering on the weld expands it. On thick sections it is done after every layer of weld. Often used when welding cast iron or other metals with a low COE (Coefficient of Expansion).
Is there required size for a seal weld per AISC?
The required size for a seal weld per AISC is eighteen foot length. AISC also specifies minimum weld size based on the thicknesses of the members joined.

What is the angle of the bevel of a butt weld?
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.
How much bevel angle shoul be there in between butt weld?
27.5 degrees

What does TCU4a weld symbol mean?
A TCU4a weld is a Corner Jount (TC), Unlimited Thickness Full Joint Penetration (U), Single Bevel Groove (4), and (a) is the welding process.
Who is better astm a 105 or astm 197?
ASTM A105 is a Carbon Steel material spec used in forged fittings, such as 2000# or higher socket weld or threaded fittings, forged flanges, etc.. ASTM A197 is a Malleable iron material spec used in 150# socket weld or threaded fittings.
How do you weld a bevel broken gear?
You don't. You will never keep the tooth profiles right and will screw up the heat treatment. Get another gear!

When welding a single bevel butt joint which side should be welded first?
You always weld the side with the preperation first, then if you get incomplete penetration you can grind the back out
When you specified welded fitting by WPHY?
can you weld two fittings have the specified the first is API 5L X60 and A234 WPHY60
What is a penetration weld?
a weld that does exactly what it sounds like, the molten metal that is created when welding is created all the way through the materials being welded. for example, if it is a 1/16th inch steel plate, a full penetration weld would create a molten bead from the front to the back of the plate. A full pin weld is when u have a bevel on one side that u weld first flip it over arc air gouge the other side and weld that side up
