SUMMARY

Electric magnets do not significantly affect welding quality due to the properties of molten metal. Specifically, iron, a ferromagnetic material, loses its magnetism when heated above the Curie Temperature, which is lower than the melting point of the metal. As a result, during the welding process, the arc welder effectively destroys any existing magnetism in the material. This means that while electric magnets may influence the alignment of welds theoretically, they do not have a practical impact on the quality of the weldment.

PREREQUISITES
  • Understanding of ferromagnetic materials and their properties
  • Knowledge of the Curie Temperature and its implications in welding
  • Familiarity with arc welding techniques
  • Basic principles of metallurgy and crystalline structures
NEXT STEPS
  • Research the effects of temperature on ferromagnetic materials
  • Learn about the Curie Temperature in various metals
  • Explore advanced welding techniques to mitigate arc blow
  • Investigate the crystalline structure of metals and its impact on welding quality
USEFUL FOR

Welders, metallurgists, and engineering students interested in the relationship between magnetic properties and welding processes.

[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.
