In welding, the ratio of the strength of a joint to the strength of the base metal expressed in percent.

why is it important only to strike the arc in the weld joint
When a welder makes a small weld bead to "tack" a joint together so it will not move. This makes it easier to weld a joint without having to clamp it.Tack welding is when a welder makes a small bead to "tack" the metal into place for the final welding.
TKY weld joints are tubular joints used for welding. They are expressly used for when fabrication of a structure is necessary.
I am not sure but I would assume two things about joint design and its effect on the weld and visa versa: penetration and overall strength of the weld would depend greatly on what grove you are welding in or on and the amount of distortion would vary greatly depending on how large of root opening and weld size etc.

why is it important only to strike the arc in the weld joint
When a flanged corner joint is specified, the other side of the edge weld symbol is often a groove weld symbol. This indicates that a groove weld is required on the opposite side of the joint to ensure proper joint strength and integrity. The combination of both weld types helps to achieve a robust connection in the assembly.
It is a weld made by melting the edges of the materials to be joined, but adding no filler metal to the weld.
A partial penetration joint is a type of weld joint where the weld does not fully penetrate through the thickness of the materials being joined. This results in the weld metal being only partially through the joint rather than completely through. It is often used when full penetration is not required for the application.
Threading joint, weld joint, Flanges joint
probably a weld.
joint can be defined as two metals pieces come togather,this can be inform of flat. while in weld the joint is made by fuse both pieces togather
A welder utilizes technical drawings to determine what type of joint he must weld , joint preparation, where on the joint the weld must be placed, the size of the weld, and so on . Certain structures require this specific information , in order to be safe , sound , etc.
A slot weld is a weld type made in an elongated hole (or "slot") in one of the joint members.
It is the first pass in a multiple weld joint.

If joint efficiency is 0.7 then there is no radiography,if it is 0.85 then 10% radiography of the total length of welding and if joint efficiency is 1.0 then 100% radiography is required.
