Sheet Metal Weld Studs
When designing a sheet metal component that needs a fixed male thread (stud) you have 2 options. The first is to specify a flush head stud which is pressed into a pre-pierced hole in the sheet. These studs can be inserted into aluminium, mild steel and stainless steel components and come in a range of thread sizes and lengths. The advantage of using a pressed in stud is the accuracy of the hole for positioning the stud can come from the CNC punch press or laser machine. The down side is the fact that the stud head can be seen pressed into the sheet metal and can still be visible even when a part has been powder coated.
The second option is to use a weld stud, which is shown in the picture above. There are no holes pierced into the sheet so the accuracy has to come from a stud welding jig, which is normally a plate with positioning holes. This plate is positioned on top of the work piece and a weld stud gun is used to fire the weld stud into place. The advantages of this production method is that the weld stud is not visible from the front face which can be an advantage when attaching earth or fixing studs to a front panel. The disadvantage is that this method of production is slower than pressing in a stud so as ever with all these sheet metal processes you pays your money and takes your choice.
