it's not. Welders do use a chisel/hammer to knock the slag off, but a wire brush will do the same thing. Some welders do use a hammer to align their fit-up when the tack is still hot, but not after they have welded. If the slag is left on, it may cause expedited corrosion, this is why it should be cleaned, but in most top quality shops - a wire brush is used.
It is necessary to hammer a weld joint after welding CI to CI as the induced stress are relieved to a large extent and also the cracking can be avoided in case of CI

Why is it necessary to bevel an edge before welding it?
Beveling an edge before welding is necessary to ensure proper penetration of the weld metal into the joint, which strengthens the connection. It creates a V-shaped groove that allows for better access to the joint, facilitating even heat distribution and reducing the likelihood of defects. Additionally, beveling helps to achieve a more uniform weld bead and can improve the overall appearance and integrity of the final weld.
What is staggered welding?
STAGGERED INTERMITTENT FILLET WELDTwo lines of intermittent welding on a joint, such as a tee joint, wherein the fillet increments in one line are staggered with respect to those in the other line.Regards, Dineshraj.m
What is difference between seam welding and spot welding?
The only difference between the two is that projection welding requires preparation of the joint members in the way of adding a preformed dimple or projection. Spot welding is used without such preparation to the joint members. it's just heat and pressure.
What is slag from welding?
Slag is the residue left on a weld bead from the flux. It shields the hot metal from atmospheric contaminants that may weaken the weld joint. Slag can also be globules of molten metal that are expelled from the joint and then re solidify on the metal surface. in either case, they are usually chipped away with a slag hammer.
What is intermittent welding?
intermittent welding (also known as skip welding) is a pattern of welding that allows the weld joint to cool by welding in a series of "skips" on opposite or far sides from the last bead. This pattern is often used for thin material as it is likely to warp if overheated.
How is the root opening size determined in welding?
the root opening is the distance between joint members at the root of the weld before welding. the root opening must be accurate so that excess welding is not necessary.
How can a gap in a joint be closed by welding?
by welding we add some filler material which will fill the gap between the joint.
What is a tky weld joint?
TKY weld joints are tubular joints used for welding. They are expressly used for when fabrication of a structure is necessary.
What is a welding chipping hammer?
A welding chipping hammer is a hand held tool, like yourself. It is used for removing slag after the SMAW or flux core process.
Can a threaded joint be welded?
yes ,we can weld this. welding is the process of joining two materials .we can join this by spot welding or by arc welding.
What is positional welding?
A welding position is the orientation of the weld joint, whether that be flat, horizontal, vertical, or overhead.
Why is it necessary to bevel an edge before welding it?
Beveling an edge before welding is necessary to ensure proper penetration of the weld metal into the joint, which strengthens the connection. It creates a V-shaped groove that allows for better access to the joint, facilitating even heat distribution and reducing the likelihood of defects. Additionally, beveling helps to achieve a more uniform weld bead and can improve the overall appearance and integrity of the final weld.
Why is the tail used in the welding symbol?
The tail in a welding symbol is used to provide additional information about the welding process or specific requirements for the joint. It can indicate the type of weld, reference standards, or any special instructions that are necessary for the fabrication. By including this information in the tail, welders can ensure that they follow the correct specifications for the project.
What provides the joint guidance in semiautomatic welding?
In semiautomatic welding, the joint guidance is typically provided by a combination of a welding torch or gun and a guiding mechanism, such as a track or fixture. The welder manually controls the torch while following the joint's path, ensuring proper alignment and penetration. This system allows for flexibility and adaptability in various welding positions and joint configurations while maintaining consistent quality. Proper training and technique are essential for effective joint guidance in this process.
What is a Lap Joint Stub End and what is it used for?

What is your core competency for this position?
Depends on applicants expertise. If you are a welder, tell them what welding processes you knew, then what welding joint design you can weld and the welding position you can perform.
Joint efficiency of weld?
In welding, the ratio of the strength of a joint to the strength of the base metal expressed in percent.----
