Welding

One of the best part of manufacturing engineering is Welding .Welding history is not very old , the experienced gained  during the second world war forced to develop a technique to join the broken parts of equipment , hence form there welding become the essential parts of manufacturing . Now days its utilization ranging from a simpler household to aircraft industry

Let’s defines welding in a very simpler term or say layman language

WELDING- is nothing but a technique of joining similar or dissimilar metals by using heat or pressure

Hence in a layman language it’s a joining process by using heat (current)

Field of application -welding field is very versatile , its find usability in many areas and sectors like

1. Foundry
2. Ship manufacturing 
3. Railways
4. offshore 
5. Aircraft industries & Nuclear sector.......................................... and so many   .

Types of welding process

there are so many types and variant of welding process some of them are listed here 

Arc Welding 

• Flux Cored Arc Welding (FCAW)
• Shielded Metal Arc Welding (SMAW)
• Atomic Hydrogen Welding (AHW)
• Gas Metal Arc Welding (GMAW)
• Gas Tungsten Arc Welding (GTAW)
• Plasma Arc Welding (PAW)
• Submerged Arc Welding (SAW)                           

Oxy-fuel gas welding

• Air acetylene welding
• Oxyacetylene welding
• Pressure gas welding 

Resistance Welding

• Resistance spot welding
• Resistance seam welding 
• Projection welding 

and so on,
