Why copper electrode does not melt while steel melts in spot welding?

Coppers conductivity allows electrons to flow much more freely than does iron. Internal resistance converts some of the electrical energy to thermal energy and heating occurs. Since iron has a lower conductivity (the same as higher resistance) than copper more of that electrical energy is transferred to heat.

Copper has a higher melting point than steel, so it does not melt during spot welding. Additionally, copper has higher thermal conductivity, which allows it to distribute heat more efficiently and prevent it from concentrating in one spot. This combination of a higher melting point and better heat dissipation makes copper electrodes suitable for spot welding applications.

Which conducts heat faster steel copper or metal?
Steel and copper are both metals, but copper is the best conductor.
Why is steel not suitable for making the positive electrode?
Actually alkaline batteries use a steel cup coated with carbon as the positive electrode. However the steel is purely structural to support the carbon coating and to prevent leakage of the electrolyte. It does not participate in generating the electricity.
What is thermite welding?
Thermite welding is all about using thermite for welding steel or iron. Thermite is actually a mixture of iron oxide and powdered aluminum.
What happens when steel wool is added to copper sulphate?
Copper is deposed on the steel wool.
How steel conduct more heat than copper?
That is NOT correct. Copper conducts heat better than steel.
What is the electrode required for welding mild steel pipe with EN 19 forging?
what is the recomended welding electrode for EN-19 greade
What is the specification of welding electrode E6013?
The E6013 welding electrode is a versatile, all-purpose electrode with a coating that provides smooth arc characteristics and good penetration. It is commonly used for general welding applications on mild steel and is known for producing clean and minimal spatter welds. The E6013 electrode can be used with both AC and DC welding machines.
What are welding electrodes used for?
Welding Electrorodes or Welding Rods are used in arc welding. Arc welding is a special type of welding which uses a welding power supply to create an electric arc between the base material (e.g. steel) and the electrode. The Welding Ectrorodes can be used for all weldable aluminum and mild steel.
How do you weld spring steel?
hello what is filler metal (electrode) for welding of spring steel like 1.5142, 1.5225, 1.7138? regards
How can welding copper to stainless steel?

What does mean E6013?
E6013 is a mild-steel, all position, general-purpose welding electrode (rod).
What is the temperature of welding arc to weld metal?
Depends on the metal, but for steel it is hot enough to melt the steel- and steel melts at 2600-2800 degrees F.
What filler metal is used to weld 308 stainless steel?
dissimilar steel grades and the unknown grade ss can easily welded with the help of 680CGS lnt welding electrode
What does E 308L-16 electrode mean?
e=electrode 308=AWS standard for stainless steel L=carbon compound 1=welding position(all position) 6=characteristic
What is a stainless steel welding rod?
Easy. A rod or electrode used in welding stainless steel. Or to "clad" a surface with stainless steel. (Nothing more than laying down a layer or layers of stainless.) MIG wire also comes in stainless steel. Their are different types of stainless steel and rods/wire/electrodes to use on them.
Does steel melts?
Of course steel melts. That is how is shaped into steel objects.
What are the ten difference between TIG and MIG welding processes?
ElectrodeTIG welding uses a tungsten electrode that is not consumed during the welding process. MIG welding uses a metal electrode that doubles as filler material for the weld and is consumed during welding.Shielding GasTIG welding primarily uses argon as a shielding gas, with helium occasionally used. Argon is also the primary shielding gas used in MIG welding, but argon mixtures and carbon dioxide are often used for different applications.Filler MaterialTIG welding requires a separate filler material in rod or wire format because the electrode is not consumed. MIG welding delivers the filler material via the electrode.Work Piece MaterialsTIG welding can be applied to just about any metal, from steel to aluminum and exotic alloys. MIG welding was developed for nonferrous metals, but can be applied to steel.DifficultyTIG welding is considered to be more difficult than MIG welding because tighter tolerances have to be maintained between the electrode, the filler rod and the work piece.
