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.

How can arc blow be controlled?
It can be controlled by connecting the work lead to tha end of tha weld joint and than welding away from the work leadThe ARC blow can be controlled by connecting the work lead to the end of the weld join. Then you will have to weld away from the work lead.
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.
Difference between weldolet and sockolet in piping?
Weldolet has a Bevelled end to butt weld the pipe whereas in sockolet the pipe/tube goes inside it and there it is fillet welded.
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?
A transverse crack goes across the weld from side to side. A longitudinal crack travels along the weld, sometimes from end to end but not always.
When laying out a 2 on 12 stitch weld from the end of the weld to the start of the next weld is it 12 inches?

What does weld return on top means?
"Weld return on top" typically refers to the practice of positioning the weld bead on the upper side of a joint, ensuring that the visible surface has a consistent and clean appearance. This technique is often used in projects where aesthetics are important, as it helps prevent weld spatter or excess material from appearing on the more visible side. It can also contribute to the structural integrity of the weld by ensuring proper penetration and fusion in critical areas.
How can arc blow be controlled?

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.
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.
