The size of the welding rod needed to do the root pass should be the same as the root gap, although in practice, the most common root gap is 1/8" so that the size of the rod to do it is also 1/8".

What is meant by the term welding and draw various welding symbols?
Welding is the process of joining two metals, usually involving a heat source. Welding symbols are the symbols used on part prints or assembly drawings to show size and type of weld, the specific welding process, and many other variables pertaining to that particular weld. A welding symbol looks like an arrow pointing to the location of the weld, with a horizontal line 'carrying' other symbols and numbers that describe how to make that weld. A picture of a welding symbol can be found when an image search is done.
Three condition of electrode that could affect weld bead shape in sheilded metal arc welding?
The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.
What is the welding method and welding rods for weld EN 24 steel?
d2
What is welding generator?
A welding generator is an electricity generator that is commonly used in places where the power needed to arc weld is not readily available. They are usually powered by gas or diesel engines and have a high, stable energy output suitable for powering a welding machine.
What is a fusion weld?
A fusion weld has no filler material. The pieces to be joined are touching and heat is applied at the joint. The edges melt and "fuse/weld" together. TIG or Oxy-fuel Welding is used. This type of welding is considered to be pure as nothing is added to the weld.
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.
What is the filet weld size required for weldolets to main pipe joint?
wildly welding main pipe the are fillet weld or butweld
What are two effects that joint design has on the completed weld?
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.
What is 4g welding?
4G is a welding position. The '4' means the weld is to be made in the overhead position. The 'G' means the weld is a groove weld.

Do you go faster or slower when welding uphill?
Travel speed, as it is called, should be the same in all welding positions. Travel speed determines the size of the weld.
What does a welding instructor do?
Teach you how to weld
Butt-weld and grrove weld?
First, Butt-weld is short for a butt groove. Welding in a butt-groove starts at the throat of the butt-groove. The first weld point could be a tack-weld: holding the two materials to be welded together. The throat is measured and filler metal and electrode are determined to create the root pass.
What qualifications are needed to obtain a welding certificate in the central Ohio area?
You must complete a welding certificate training course that will teach you a variety of skills needed to weld. It varies on hours and price according to what course you take.
How close can one weld be to another weld?
Depends on what you are welding, but generaly welds can meet, or even weld on top of a weld.
Three condition of electrode that could affect weld bead shape in sheilded metal arc welding?
The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.
What tack welding size and spacing is needed in relationship to material thickness?
If tack welding is just for the purpose of holding the part in place then the welding tack size should be enough to hold it in place and should not exceed the final welding size. Spacing and number of tacks can vary depending on your requirement, but if enough space is available then try to avoid the consecutive tacks in the heat affected zone area of the previous welded tack. Usually spacing of 25 to 30mm is enough, increase the spacing as there is an increase in the leg size of the tack weld.
