Welding
If you want to become a professional welding service, there are a few things to note about the shape of the weld.I will examine the features of the class so that you are not curious and I give it for free.The two key methods of joining metals are the mechanical process and metallurgical process.Welding belongs to the latter

and is an excellent metal joining method.However,it has merits and demerits compared with other joining methods due to the high concentrated heat energy generally used.
Merits;
Simple joint.
  • Cost savings (material,labor,ete.)
  • High joint efficiency (good water and air tightness)
  • No limitation to thickness of material joined.
  • Relatively low noise pollution.
Demerits;
  • Strain due to local heating and coll.
  • Residual stress due to local heating and coll.
  • Uneven metallographic structure and quality.
  • Possibility of brittle fractures.
  • Possibility of weld defects. 
Maybe there is exchange of ideas with me on welding feature, please the share below.
