Not exactly sure what you're asking but this may be the info you want. When stick (SMAW) welding as you progress with the bead directly under the arc a slight depression forms. Called a crater. When you get to the end of the bead if you pull the electrode away the crater is there which promotes crater cracks. By pausing at that point and actually backing up a little the crater is filled. With practice the weld is the same height and width all the way to the end. Hope this is what you are asking about.

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.
Difference between weldolet and sockolet in piping?

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 a tranverse crack in a weld?

What is the full form of WNRF flange?
W : Weld N : Neck R : Raised F : Face, It is a type of flange used for butt weld end connection...Refer ASME B 16.5
How close can one weld be to another weld?
Depends on what you are welding, but generaly welds can meet, or even weld on top of a weld.
What car takes a 72 inch driveshaft?

Why is filet weld necessary while welding slip on flanges to a pipe end?
It is the only type of weld you can make to seal this type of joint. There are flange ends that can be welded onto pipe with a butt weld, but sockets and slip-ons must be fillet welded.
