This will depend on the welder in question. Some of them are faster than others and some are a little slower.
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.
This welder is certified to weld on pressure vessels. Testing is done on the weld either by X-Ray or pressure test. The root pass is inspected then the final pass is inspected during the test. If either inspection turns up a flaw, the test is over and you fail.
A weld symbol is the shape drawn on a Print to tell the welder: how to prepare a welding joint, what process can be used to weld (mig, tig, arc, etc) what filler rod to use, how wide and long the weld should be, how to deal with the weld after your done (grind flush, brush clean, or nothing) and a million other things.... Its a tool that design engineers use to communicate what the weld needs to be to meet their design specifications.
circumfrencial weld is sometimes referred to as Girth weld. its just another term.
Yes, you can weld steel to steel. You can use steel welding rod.
3 bead cap
can weld aluminium with a mig or tig welder
about 150 00 an hour
SP welder means Structural purpose welder.
Tig, mig , or If you are as good as me stick welding will all work
Weld
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.
yes
This is used differently in different countries. But generally, if a welder is contracted to do say 100 weld joints, of a 1" pipe, then the total work involved is 100" dia welding work. If 100 weld joints of a 2" pipe is 200 weld work and so on.

probably a editing mistake; question should be: can you read map welder id numbers?
When we are using the tig welder we getting welding defects on our blanks, but when using the plasma weld no defects are found
