How many electrodes are needed for welding a pipe from API 5L- x60 with wall thisknes 20mm... 1

[albanbulku]

i need to make a prevention for weldings in a pipeline and need some advices becouse i am new in this field.

 

[Cockroach]

Two and a half. Make two passes at 8 mm each and then the final third pass to cap the weld.

You first need to calculate the volume of weld metal required to fill and cap the joint.

It depends on electrode type, diameter, joint type, multiply by your cross sectional area of the weld joint and circumference of the pipe. This give you the volume of fill rod. Back out the rod w an appropriate waste factor.

Hello everybody:

In addition to what the above posters have said, what does indicate the Welding Procedure Specification for that job? I suppose that you have one.

thank's to all of you for your answers.
I am trying to determine how to pay the welders.
Can anyone recomend me for the payment of welders?

In China, about $0.55 US a day. In Abu Dabi, perhaps less after a good beating. I suppose you have labor laws where you are, might be a place to start. You post such a ridiculous question, I can't help but laugh!

albanbulku,
Per hour/day/week/etc., prevailing wage laws, supply/demand of/for welders or by the weld size and number of welds made (piecework) or by combinations thereof. Your question indicates that you are way over your head for the position you are in.

I imagine you should pay them in the local currency. Some good methods are physical transfer, check, or electronic transfer.

Ok i will offer them only the lunch and dinner so they will be happy
