Welding Thru deck
The best welding results are achieved through adherence to recommended job-site procedures and conditions. Factors such as painted beam flanges, water, deck fit-up to the beam, and inadequate power can seriously hamper satisfactory welding.
Here are some important site requirements:
1- Top flanges of beams must be unpainted (or at least a strip where the studs are to be welded).
2- Remember if fire protection coating is applied to the rest of the beam (top uncoated) prior to stud welding, that touch up may be required after the studs have been welded. (The heat from stud welding may activate the fire protection)
3- The beams should be free of heavy rust and mill scale
4- The beams should be free of dirt, sand and other materials
5- Galvanised beams will need to be ground back to remove the galvanising
6- Water on the deck, or between the beam and deck must be removed before welding
The Nelson System
Electric-Arc stud welding is the most common process and is utilized whenever metal is fabricated. It is used to best advantage when the base plate is heavy enough to support the full strength of the welded studs, but is sometimes used with lighter gauge material.
The Stud is held in the welding gun with the end of the stud placed against the work. The cycle is started by depressing the trigger button start switch. The stud is then automatically retracted from the work piece to establish an arc. The arc continues for predetermined period of time until portions of the stud and the base plate have been melted. Then, the welding gun automatically plunges the stud into the molten pool of metal and holds it there under spring pressure. At the same time, the welding current is stopped and, when the molten metal solidifies, the weld is completed and the welding gun is removed from the stud.
The molten metal is held in place by a ceramic ferrule which also serves to shield the arc. The weld metal is deoxidised by a flux in the weld end of the stud. This results in a dense, strong weld which will develop the full strength of the stud and base plate. The weld cycle depends on the diameter of the fastener and materials being joined and varies in time from 1/10 to 1-1/2 seconds. Welding currents range from 250 to 3000 amps.
