What is the first pass in a bevel pipe weld?
root pass
Butt-weld and grrove weld?
First, Butt-weld is short for a butt groove. Welding in a butt-groove starts at the throat of the butt-groove. The first weld point could be a tack-weld: holding the two materials to be welded together. The throat is measured and filler metal and electrode are determined to create the root pass.
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 filet weld size required for weldolets to main pipe joint?

How much bevel angle shoul be there in between butt weld?

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
Is it better using welded fittings or threaded fittings on 2 inch piping for inert gas distribution networks?
If you have a lot to install i would weld. 2 in. is a very big pipe to screw together
How do you weld a bevel broken gear which type of weilding rods are used to weld gears?
When welding something like gears, you need a rod that gives good penetration, and also has a fairly high density. I would probably use 6011 rods. These are the best for any "out of position" weld. Just be sure it's a close weld. Otherwise you'll get a lot of spatter (which you would then need to grind off).
