Which welding is used for GI pipe?

GI pipes can be welded with the simplest E6010 electrode in arc welding. Main problem is the tin coating on the pipe in heat affected zone evaporates and corrosion resistance in the area is affected. Main purpose of galvanizing the pipe is lost as selective corrosion starts in the weld area and spreads to other areas.

What’s the best way to weld galvanized steel?

For galvanized steel, a standard arc welder is probably the best way since arc welding is versatile, and the alternating currents allow you to create a good arc that can melt the flux quickly. Arc welding sometimes creates flux, so you may want to work outside if possible.

What is the strongest welding process?

TIG welding produces cleaner and more precise welds than MIG welding or other Arc welding methods, making it the strongest. That said, different welding jobs may require different methods, while TIG is generally stronger and higher in quality, you should use MIG or another method if the job calls for it.

Is it possible to weld GI pipe?

GI pipe is also Carbon Steel and having carbon less than 0.3\% and they are mostly made to ASTM A53 spec. It is dip coated in hot Zinc metal bath for corrosion protection. Normally inside as well as outside surfaces are coated. Both AWS Electrode, E6013 and E6010 can be used for welding.

What is difference between E6013 and E6010?

E6010 electrodes can only be used with direct current (DC) power sources. E6013 electrodes produce a soft arc with minimal spatter, offer moderate penetration and have an easily-removable slag. These electrodes should only be used to weld clean, new sheet metal.

How do you weld a GI sheet?

Galvanized steel can be welded by manual electric arc welding, melting electrode gas shielded welding, argon arc welding, resistance welding, etc.

Which is better MS or GI?

Higher longevity and Durability. Mild Steel Pipes are carbon steel pipes that contain less than 0.25\% of carbon which makes them easy to use and less hard. This ensures that the pipes stay malleable, ductile and durable. GI pipes can be welded into various shapes and sizes as per the requirement.

Which is costlier GI or MS?

Question: What is costly gi or ms pipe Answer:- Gi Pipe is nothing but same MS pipe but additionally galvanized with Zinc Coating to Galvanising Standard IS4736-1986 standard to 360 gsm, So GI Pipe is costlier than MS Pipes.

Can a GI pipe be welded with arc welding?

, I have worked in welding department of Mazagon Dock Ltd on shipbuilding projects for 15 years. GI pipes can be welded with the simplest E6010 electrode in arc welding. Main problem is the tin coating on the pipe in heat affected zone evaporates and corrosion resistance in the area is affected.

How do you remove zinc from GI pipe welding?

Normally, Zinc on GI pipe welding end/edges, is removed by grinding, say for 1/2″ (12mm) long, from fusion line to avoid zinc metal burning, sparkling and weld contamination with Zinc metal. Large industries/critical users, use E7018 electrodes, for better weld quality.

What type of welding rod to use to weld pipe?

Depends on how thick the pipe is and what it’s being used for. 6010 is a “junk rod” that can stand a lot of contaminates and still produce. It comes in as small as 1/16″ plus it welds cooler “high chill rate” than most welding rods so you loose less galvanizing in the heat effected area.

What is the meaning of GI pipe?

Spar Steel is known and trusted for manufacturing with the latest advanced technology a wide range of steel pipes and tubes like MS/ERW Pipes/Black Pipes /GP/GI Pipes/GIS Tubes/Galvanised Pipes/Galvanised Tubes /ARAMCO Pipes & Tubes, etc. based on international parameters. GI stands for “galvanized iron.”
