The most common pipe welding testing position is the 6G position, which involves welding at a 45-degree angle while the pipe is in a fixed position. This position tests the welder's ability to perform welds in all directions and is particularly challenging due to the varying angles involved. It is widely used in various industries, including oil and gas, to assess the skills required for complex pipe welds. Other positions like 1G, 2G, 5G, and 6G are also used, but 6G is considered the most rigorous and indicative of a welder's overall competence.
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
MY question is (WHAT IS DOWNHILL WELDING) The correct term is Down Hand Welding. Most welds in the vertical position are made from bottom to top. Down Hand means welding from the top to bottom. These welds are usually made on thin metal as the heat input is lower, thereby reducing penetration/burn thru.
I believe that the most effective and common way to inspect a friction weld is by ultrasound.
2 basic types, Gas shielding, and flux shielding. Gas shielding comes from compressed tanks of inert gas such as argon. these gases are pumped through the welding hose and over the weld pool. The flux type protects the weld by covering it in a layer of slag that prevent it from being contaminated by the surrounding air.
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".

It is most commonly used, due to the fact the materials that can be welded this way are very common, and the equipment is is relatively inexpensive.
It is called aluminum welding. Aluminum can be TIG welded, the most common method, or oxy-fuel welded, or stick welded, or MIG welded.

Argon is the most common gas used in gas metal arc welding.
Heat rises so in my experience it is always overhead that has the most heat input.
The most common animals that die from biomedical tests are mice. The second most common animals are rats.
There is no actual website named "Welding Supply", but these words do feature in the names of many stores who primarily deal in welding equipment. Some of the most common items related to welding include personal protective equipment and spare parts.
