A thread-o-let is a female by weld connection. It is commonly seen on large diameter pipes where a valve or other connection (typically much smaller in diameter) is made.
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.

The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.
A fillet weld in any single continuous weldmay underrun the nominal fillet weld size specified by2 mm [1/16 in] without correction, provided that theundersize portion of the weld does not exceed 10% of thelength of the weld. On the web-to-flange welds on girders,underrun shall be prohibited at the ends for a lengthequal to twice the width of the flange.
let say you have 4" dia. of pipe and 10 welds so the total diameter inch of weld are 4 x 10 = 40 dia. inches
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.

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.
Inch dia = Number of weld joints X Size of the pipe
In order to weld pieces of 6mm steel you can use any type of welder. Depending on how strong and how pretty the weld needs to be will determine the type of welder you choose.
In a fillet weld, the leg and size are the same for the convex weld.
