Custom sheet metal welding and assembly

Products Details

Sheet Metal Fabrication Processes: CuttingBending or Forming, Tapping or RivetingWelding and Assembly.Threads are playing an important role in assemblies. There are 3 main methods to get threads: Tapping, riveting, install coils. 1. Tapping threads Tapping is a process making threads in the holes for sheet metal parts or CNC machined parts with tap machine and tap tools. It is widely used on some thick and hard material such as steel and stainless steel parts.Press fitting is suitable for some pins and shaft assembly, and widely used in machined parts, sometimes needed in sheet metal projects.Sheet metal assembly is the process after cutting and bending, sometimes it is after coating process. We usually assemble parts by riveting, welding, pressing fit and tapping to screw them together.For some thick but soft materials like plastic machined parts, we usually install Heli-coil inserts into the machined holes to get threads for assembly. HY Metals can do laser welding, Argon-arc welding and Carbon dioxide arc welding. According to the metal welding works level, it is divided into spot welding, full welding, water proof welding. We can meet all your requirement on metal welding for your assemblies.Sometimes, we will polish the welding marks to get a smooth surface before coating.For thin metal or soft materials like aluminum and plastic parts, riveting and install coils will work better. 2. Riveting Nuts and Standoffs Riveting is the simplest and most commonly used assembly method in sheet metal processing. Riveting can provide longer and stronger threads than tapping for thin metal plateThere are a lot of Nuts, screws and standoffs for riveting. You can get all standard size PEM hardware and some MacMaster-Carr hardware from HY Metals for your assembly. For some special hardware we can’t source in local shops, you can provide to us for assembling.Welding is another commonly used assembly method in sheet metal fabrication. Welding can make several parts joint together strongly.
