Basic test is to cut across the weld and polish the metal. Most times the weld can be seen as a different shade. Inclusions and incomplete fusion are visible You can cut strips across the weld joint and bend them to look for fracturing. Ultimate test is to x-ray the weld. Defects and incomplete fusion can be seen. Same process as an x-ray of your body. Also a section can be cut from the joint and subjected to a tensile test where the piece is literally pulled apart. A good weldor knows when he has produced a perfect weld just by observing the weld bead as it is deposited. Using the correct electrode produces a weld slightly stronger than the base metal.
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.
No inter-run penetration in welding refers to the absence of fusion between successive layers or passes of weld metal. This means that each layer of weld does not adequately bond to the layer beneath it, potentially leading to weak joints and reduced structural integrity. Achieving proper inter-run penetration is crucial for ensuring the strength and durability of the weld. It can be influenced by factors such as heat input, welding technique, and joint preparation.
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.

Incomplete fusion or poor penetration in welding can be caused by inadequate heat input, improper welding technique, improper preparation of the joint surfaces, insufficient welding current, incorrect welding speed, or using the wrong welding process for the specific material being welded.
it kind of welding for welding thin sextodecimos with depth and influence in places where welding company's and pullulation bed with a good quality for other fashion seems to be appropriate. If you are asking "how do you determine the tensile strength of MIG welding?" The aswer is it is stated on the box and spool. The number 70 means 70,000 lbs tensile strength same as the 70 in 7018 electrodes.
In welding manganese and carbon steel, it is recommended to use an E7018 electrode. This electrode provides good penetration and strength for welding these two materials together. Additionally, it offers excellent slag control and produces clean welds.
In DC welding, electrode positive (DCEP) produces more heat at the workpiece, leading to deeper penetration and faster welding speeds. In contrast, electrode negative (DCEN) focuses more heat on the electrode, resulting in shallower penetration and slower welding speeds. AC welding alternates between these effects with each cycle.
Using an electrode positive in welding processes can provide advantages such as better penetration, increased welding speed, and improved control over the welding arc.
MIG welding with flux core wire offers advantages such as higher welding speed, better penetration, and increased portability compared to other welding methods.
Flux core welding gas offers advantages such as increased welding speed, deeper penetration, and better performance in windy conditions compared to other welding techniques.
E6010 is a designation for a type of welding electrode used in arc welding, specifically for stick welding (SMAW). The "E" stands for electrode, while "60" indicates the minimum tensile strength of 60,000 psi. The "1" signifies that it is suitable for all-position welding, and the "0" denotes that it is a cellulosic electrode, which is known for its deep penetration and ability to perform well in outdoor conditions with dirty or rusty materials.
Root opening in welding refers to the gap or space between two pieces of metal at the joint's root, where the weld begins. It is crucial for ensuring proper penetration of the weld metal, which affects the strength and integrity of the joint. The size of the root opening can vary depending on the welding process, joint design, and material thickness, and it must be carefully controlled to achieve optimal results. Proper root opening helps facilitate good fusion and minimizes the risk of defects such as incomplete penetration or porosity.
Flux core gas welding offers advantages such as increased welding speed, deeper penetration, and better performance in windy conditions compared to other welding methods.
