flat, horizontal, vertical and over head position
Look at a wall. Imagine welding on that wall from left to right or right to left. That is horizontal welding.
The letters EN , on a welding electrode , indicate "electrode negative" , that is the electrode is to be used with a DC current , in the negative position, or polarity.
When the weld is made from under the joint.
The significance of the arc welding process are:-1. Flux Shielded Manual Metal Arc Welding is the simplest of all the arc welding processes.2. The equipment can be portable and the cost is fairly low.3. This process finds innumerable applications, because of the availability of a wide variety of electrodes.4. A big range of metals and their alloys can be welded.5. Welding can be carried out in any position with highest weld quality.6. The process can be very well employed for hard facing and metal deposition to reclaim parts or to develop other characteristics like wear resistance etc.ARSHAD H BHUTTOSALES ENGINEER-LINCOLN ELECTRIC WELDING PRODUCTS
Depends on applicants expertise. If you are a welder, tell them what welding processes you knew, then what welding joint design you can weld and the welding position you can perform.
The meaning of 6G position in Welding is mean that the pipe or test piece inclined to 45 degree and not rotated during welding process .
Actually I usually crowd the puddle when welding vertical up. The longer the arc length the more the arc can wander.
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.
Your question is incomplete. Which process? Which electrode? What is the basemetal, which position? etc etc
5G is a welding position for pipe. The pipe is in a fixed, horizontal position. There is a groove along the circumference of the pipe where the weld is to be made.
flat, horizontal, vertical and over head position
Look at a wall. Imagine welding on that wall from left to right or right to left. That is horizontal welding.
A welding position is the orientation of the weld joint, whether that be flat, horizontal, vertical, or overhead.
It can be. Basic welding techniques can get you started in the welding field. Stick welding in the flat position for example. The more experience you get usually translates to more money. Certain processes take more skill such as TIG or plasma welding as well as pipe welding and underwater welding. These are considered highly skilled.
Flat position welding is when your job is in a horizontal position the easiest and best position to do welding, then you get vertical up position where the trick is to weave your arc in a V formation, vertical down is used on thin material if its possible at an angle of 45 degrees last overhead that is the most difficult the opposite of flat welding where the job is upside down anytime you look directly down on your weld joint, it is a flat weld, flat position weld are not affected by gravity, as opposed to horizontal, vertical, and overhead, all of which the puddle tends to "sag" as you weld
