How Do Electric Magnets Affect Welding Quality?

AI Thread Summary
Electric magnets do not significantly affect welding quality due to the properties of molten metal. When heated above the Curie Temperature, ferromagnetic materials like iron lose their magnetism, which occurs before reaching the melting point. As a result, any magnetic alignment from an electric magnet would be negated during the welding process. Additionally, molten metal lacks a crystalline structure, further diminishing any potential magnetic influence. Overall, electric magnets do not produce aligned welds and their impact is minimal.

[SOLVED] Odd question

Forgive me, i don't know a lot about Physics...

What effect does an Elect. Magnet have on a Weldment...

IE., Does molten metal contain magnetic propertes...

See I'm wondering about the effects of Electric magnets on Welding. would a magnet produce an alligned weld... Aside from Arc Blow...

Probably not, no. Iron is an example of a ferromagnet. These loose their magnetism when heated above the Curie Temperature. This is typically lower than the melting point. So an arcwelder will destroy any magnetism in the material.
 
Magnetism is a function of the crystaline structure of metals.

In liquid form, there are no crystals.
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
