Welding Metal Decking

Shear Stud Welding to Metal Decking. Metal deck is often installed using arc spot welds either with or without weld washers.

Deck to be welded to all supports at 8 inches on center.

Welding metal decking. These are used to achieve a composite action between the concrete slab and the steel beam. When metal deck is to be welded to supports the effective fusion area is at least 12 in. There are two different types of welding methods for metal decking.

We do the difficult every day. The impossible just takes a little longer. Additionally the easy-to-use DeckGrip interlocking tool provides high shear values not attainable by button punching while weighing only 28 lbs.

Additionally load tables for most roof deck and some non-composite form deck are based on a specified minimum yield strength of 33 ksi. Individual panels of decking. We take pride in every project every sheet down to the last weld.

Welding washers are recom-mended when welding metal thickness is less than 00280 inches. Ends of deck to be welded to supports at 12 inches on center maximum and 18 inches on center maximum at intermediate supports. Another alternate might be to puddle weld a flat plate to the underside of the deck first.

Yes you can use E6022 to weld deck if you use the required preheat and you are welding group 1 deck to group 1 supporting members. CSM Metal Deck recommends the use of weld washers for support attachments with deck units less than 028 071 mm thick not required for 22 gauge. The plug weld must always be completed by a light gauge certified welder.

Quality welding of light gauge metal roof decking techo de metal cubierta or metal floor decking suelo de metal cubierta requires experience and the selection of proper amperage and electrodes. Used to attach floor and roof deck. Deck to be welded to all supports at 12 inches on center.

Arc spot welds also referred to as puddle welds. The process of welding metal decking to the steel framing is done by using a welding machine and a weld rod. Prevent holes while welding metal deck by using galvanized weld washers.

4-12 6 7-12 Deck. Diameter for arc spot welds or at least 38 in. Weld metal shall penetrate all layers of deck material at end laps.

Galvanized decking is placed on top of the steel girder as part of the concrete form and it is general practice to weld through the galvanized decking to the base metal of the steel girder. On bare uncoated steels this practice is viable and reliable means of welding studs. The most common filler metal used for welding steel deck is an E6022 electrode due to the ability of that electrode to produce welds with good penetration and wetting of the weld puddle perimeter.

Galvanized deck must be used for those roof deck systems where form deck is used to. Long for arc seam welds. These small pieces of galvanized steel are designed with a small curved to fit into the valley of metal decking.

Ironwork metal decking installation and certified structural welding. This type of weld is commonly referred to as a plug weld. Willson Iron brings hard work ethic integrity and craft to every job.

Welding the deck to the steel framing is a very common call out. Form deck is furnished galvanized prime painted or uncoated. The powerful lightweight pneumatic DeltaGrip tool fastens the sidelaps of the interlocking steel roof or floor deck with a highly effective triple punch through three layers of steel.

Due to the difficulty of side lap welding on 22 gauge and lighter metal decks CSM Metal Deck recommends. Please Note welding to any group 2 steel that does require a Low Hydrogen electrode would not be allowed using the E6022 without specific approval from the engineer of record on each jobcontract under D11 or D13. Welding must be done by a qualified welder during proper weather conditions.

Arc spot weld which is better known as puddle welding and arc seam weld which is is also called a top seam weld. Fastening Metal Deck By Welding. Fixing of metal decking and the associated work of stud welding safety netting etc.

Welding washers shall be used on all deck units with metal thickness less than 0028 Where welding washers are not used a minimum visible 58 diameter arc puddle weld shall be used. The Longitudinal shear connection between the steel section and the concrete is provided by shear connectors which normally take the form of shear studs welded to the top flange of the steel section through the metal deck. Number of decking sheets secured together with metal bands also called a pack.

Pressed steel formwork for restraint of wet concrete at slab edges. What Is A Metal Deck Puddle Weld Or Arc Spot Weld. First most structural welders who have certification are certified to AWS D11-Structural Welding Code-Steel.

For welding sheet steel eg. If you hold the subcontractor to the requirements of AWS D13-Structural Welding Code-Sheet Steel he will likely fail. A weld quality control test procedure is shown below.

Based on the detail shown the angle could fall in the flute depending on the deck layout and brace location which could make welding more difficult unless an angle is used that has a large horizontal leg.
