Skyscraper welding - questions from an engineering student

admin

Hello!I am a graduate engineering student currently working on a design project that involves identifying methods to improve efficiency and safety of structural welding... specifically for high rise structures.   I’m currently researching the welding process itself and am trying to better understand the process and equipment used.   I could use help with a few questions:*Which welding processes are most common for high rises?  One I have noted is flux-cored arc welding.  It seems like shielded metal arc welding and electroslag welding may be used also, but I am not certain if they are, or if I am missing any other common methods.*What are the requirements of equipment used for high rise welding?  Voltage, type of rod used, safety, anything else I should take into consideration.    Would a device like this be appropriate?  http://store.cyberweld.com/mixmt450c...pdItemDataTabs*Are there any common measures of how much rod will be required to complete a certain weld job?  For example, how many tons would I need to complete a 20 story building?Also please keep in mind that I know little to nothing about welding.  So any other *obvious* facts that I should know as I work on this project would be highly appreciated!Thank you for your time!
Reply:You'll probably find all the answers you are looking for in Lincoln's Procedure Handbook of Arc Welding. It give information on how much material is deposited for various methods and so on.In some ways it's not an easy read, but as an engineering student some of it will make more sense to you than it will to those who weld daily.You'll probably also find a number of other books offered by Lincoln that might be of some interest to your area of study. Books like Design of Weldments, Design of Welded structures, Solutions to Design of Weldments, Weight of Weld Metal Tables etc.http://www.jflfoundation.com/SearchResults.asp?Cat=24.No government ever voluntarily reduces itself in size.

Reply:While your at it, see what you can do about out lawing these dam body harnesses! Those two straps that go between your legs can raise your voice a few octaves when you put your arms over your head. God only knows what happens to the family jewels if you fell, and the lanyard took hold in the D-ring in the center of your back.

Reply:We welded a couple hundred tons in Tower 1, Tower 4 and the Transportation Hub at the World Trade center . SSFC Coreshield 8.  1/16 for the field. LINCOLN Ultracore 71M 1/16 CO-2 shop work. .For Sub arc LA-75 / 860 flux 5/64. One piece took 17 tons of weld metal. One piece of the hub took 3000 parts.
Reply:Time to open some books and learn some things about welding, Forums are helpful but you will get to many answers for a single question and the know it all types could derail your project. Youtube might be helpful as people post lots of safety videos. Wish today's internet was around when I was in school, I could of gone around asking questions and let people do the work for me .Last edited by NinjaRay; 10-30-2014 at 10:34 PM.
Reply:PavinsteelmanReality check . . . tons of filler . . .My biggest steel project was 360 tons of hot-rolled in the Great Basin west of the Rockies.The 'local' was between: the High Plains Drifter, and Bad Day at Black Rock.All of the filler/wire may have been - two and a half - hefty pallets.In comparison - It would take a magnifying glass to see how small I feel . . .

Reply:We were buying 20 tons at one time. A tiny twin can run 240 lbs in 8 hrs.

Reply:Sounds like a typical engineering project "I need to design a 20 story high rise building using welding and construction code, but know absolutely zero about welding or welding processes"
