Look at a wall. Imagine welding on that wall from left to right or right to left. That is horizontal welding.
1g,2g,5g and 6g in pipe welding
flat, horizontal, vertical and over head position
I know that PC stands for Horizontal-Vertical; although I am Unsure about pb.
70-represents 70,000 pound tinsel strength..the 2 represents 2 position (flat and horizontal) and the 4 is the flux/current used
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.
Unless it has been changed it is: 1G flat 2G horizontal 3G vertical 4G overhead 5G pipe
flat, horizontal, vertical and over head position
A welding position is the orientation of the weld joint, whether that be flat, horizontal, vertical, or overhead.
The 2 stands for welding position. In this case it is flat and horizontal. Have fun welding!
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 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
Flat, Horiz. and Overhead welding normally take the same amount of Amperage. The electrode angle would change.
Welding is often done on structures in the position in which they are found. Techniques have been developed to allow welding in any position. Some welding processes have all-position capabilities, while others may be used in only one or two positions. All welding can be classified according to the position of the workpiece or the position of the welded joint on the plates or sections being welded. For Fillet welds, following are the welding positions defined: 1. Flat (1F) 2. Horizontal (2F) 3. Vertical (3F) 4. Overhead (4F) For Groove welds, following are the welding positions defined: 1. Flat (1G) 2. Horizontal (2G) 3. Vertical (3G) 4. Overhead (4G) 5. Flat 1G 6. Horizontal 2G 7. 5G position 8. 6 G position ANS BY: Vijay Hemgude. Pune (India)
The pipe must be fixed (not rolled) in the horizontal position. With the pipe horizontal, the weld is vertical. The pipe being fixed requires the welder to weld flat (top), vertical (sides), and overhead (bottom). The pipe must be fixed (not rolled) in the horizontal position. With the pipe horizontal, the weld is vertical. The pipe being fixed requires the welder to weld flat (top), vertical (sides), and overhead (bottom).
A welding positioner is a work motion device that places the weldment in a location and at an angle that allows for optimum welding parameters to be used (faster travel speed, increased current, ect.) Essentially, it places the weldment so that it is in a 1G, 1F, or 2F position. Four common types of welding positioners include tilt-tables, turning rolls, head and tailstock, and universal balance positioners.

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.
