It depends on what metal you are welding and how thick it is, but in general, no. Any process that will raise enough heat for adequate weld penetration is for the most part equal.
Many factors affect welding depth and penetration, including voltage, material being welded, current, distance from electron gun, vacuum, cleanliness, filament current, and focus.
Underwater welding uses a special flux around the welding rod which produces gasses which form a bubble around the end of the rod ,excluding the water. It is difficult and never as strong, lacking penetration. It is only used when absolutly necessary.
Verticle down welding will always have lower penetration and less heat applied to the weld joint. As sheet metal is thinner and can not take excessive heat, verticle down reduces burn-through.
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.

1 Increase travel speed 2 lower amperage setting.
Vertical up welding is preferred in most instances as better penetration is achieved and the slag does not run down into the arc. Down hand welding is mostly used on thin material so as not to burn thru the metal. Travel speed is usually increased also.

what is the hardest steel for welding
Metallic Inert Gas Welding - It is a welding process that involves Electricity and a continuous Wire that is used for as a filler rod for the weld.
Radiographic testing is similar to taking of an x-ray of a weld. It checks for integrity, penetration, and other necessary factors.
One method is Ultra Sonic Sound, another Die Penetration.
