Welding of zinc coated steel can be done, but specific precautions should be taken. When galvanized steel is arc welded the heat of the welding arc vaporizes the zinc coating in the weld area. This is because the boiling point of zinc is below the melting point of steel. The zinc volatilizes and leaves the base metal adjacent to the weld.[mask]Optimization of Resistance Spot Welding Process applied [ppe]Request PDF Optimization of Resistance Spot Welding Process applied to A36 Mild Steel and Hot Dipped Galvanized Steel based on Hardness and Nugget Geometry Resistance spot welding (RSW), a

How to Strike and Establish an Arc[mask]Choose wisely when welding thin sheet The FABRICATOR[ppe]Gas metal arc welding (GMAW) is an effective method for joining light gauge metals such as carbon steel and austenitic stainless steel. Thin gauge materials24 ga. to 0.1875 in. carbon steel and 18 ga. to 0.1875 in. stainless steelare used in applications such as HVAC, automotive, mobile machinery guards and cabs, and small parts, as well as stainless steel food service and processing [mask]Welding heat treatable steels The FABRICATOR[ppe]Our shop won a contract that requires welding 4130 steel. I've been told this is a heat treatable steel. Can you tell me which different welding procedures have to be used to weld this material? The most commonly welded heat treatable steels are 4130, 4340, and 8630. However, any steel prefaced with a 41, 43, or 86 is considered heat treatable.
A36 Steel Plate is one of the most popular hot rolled, low carbon steel plates used in manufacturing, fabrication, and repair projects.A36 Steel plate adds strength and rigidity to any project at a lower price compared to other grades of steel plate. It is easy to weld, cut, form and machine.[mask]Copper NickelWelding and joining plate, sheet and pipe[ppe]When arc spot GMAW is not practical, for example because of welding position or a heavy gage, mid sheet attachments can be made by plug welding using precut holes. The holes may be circles or slots, e.g. , 1/2 in. (12.4 mm) diameter or 1 in. by 3/8 in. (25 mm by 9.5 mm) slots.[mask]How to Weld Cast Iron to Steel eHow[ppe]Welding cast iron to steel is a process that really doesn't take much time to get the hang of, even if you've never welded before. The reason for this is that steel is slightly harder than cast iron, and therefore combines fairly easily.
