Different Types of Welding Used at Construction Sites

November 16, 20220

More than 70% of construction sites in the US require welders to complete the construction project within strict deadlines. From machine manufacturing to skyscraper and mega structure constructions, everything is incomplete without welding.

It’s not surprising; welding has been in practice for ages now. But in today’s construction world, it has become a non-negotiable process without which constructors cannot even imagine giving dynamic shapes to buildings and metal products. Well, working with metals can be fascinating and empowering but very challenging at the same time. 

Only professional welders can transform the most robust metal into desired shapes as they envision. Therefore, let us shed some light on the welding techniques used at construction sites by trusted welders. 

Gas Tungsten Arc Welding (GTA Welding)

This is an arc-welding process that helps to weld together non-ferrous metals. A common method uses consumable tungsten electrodes to weld metal pieces. This welding technique requires artistic touch, trained hands, and welding knowledge. 

The process is time-consuming compared to other forms of welding techniques because of the melting point of stainless steel/non-ferrous metals. So welders need to take close care while identifying the thickness of the metal. 

MIG Welding (Gas Metal Arc Welding)

This welding technique is known as Metal Inert Gas welding, in which electrode wire and shielding gas is used. The electrode and shielding gas together heat two different metals to join. However, the welding process needs direct-current power and constant voltage to produce intense heat for melting metal. 

MIG welding is a common welding process used in many industrial sectors. This welding procedure uses four methods to transfer metal for welding. 

  • Short Cutting: In this welding, the wire is kept close to the base metal and repeatedly tapped against the metal for welding. This method is ideal for welding metal in all shapes and designs. 
  • Globular Transfer: This welding method produces rough welding beads because of bigger metal droplets. The metal welding procedure is useful in welding thick metallic plates horizontally. 
  • Pulsed Spray: The welding method involves a high-low current pulse with micro-cooling time. Because of this welding approach, the technique is useful for welding metallic plates with different thicknesses. 
  • Spray Transfer: The method transmits tiny melt metal droplets in a steady arc form. This welding process is useful for welding metals in a horizontal position. 

 

Shielding Metal Arc Welding 

Shielding Metal Arc welding is used in the fabrication industry and construction of stainless steel structures. The welding technique involves a V-groove and electric current to join the metal and stick. It can join alloyed steel, carbon steel, cast iron, stainless steel, and ductile iron. Shielding metal arc welding is also used in joining non-ferrous metals like copper and nickel but the technique does not apply to aluminum. 

Flux Cored Arc Welding

Flux Cored Arc welding has been introduced to overcome the limitations of shielding welding. This is a semi-automatic arc welding method commonly used in various construction projects. It’s a high-speed welding procedure, so the welded metal cools within no time. One of the best things is this welding procedure has multiple variables making it relevant for various construction and welding projects.
