Stud welding allows fastener elements such as threaded studs or nuts to be permanently attached to a component such as a wear plate liner, allowing it to be fitted accurately and quickly. This is a very cost-effective process, especially when performed on wear plate which is more time-consuming to drill, tap and weld.
Stud welding, also known as stud arc welding, joins a stud and another piece of metal together. The stud is usually joined to a flat plate by using the stud as one of the electrodes. The polarity used in stud welding depends on the type of metal being used.Welding steel requires direct-current electrode negative (DCEN).
Stud welding uses a type of flux called a ferrule, a ceramic ring which concentrates the heat generated, prevents oxidation and retains the molten metal in the weld zone. The ferrule is broken off of the fastener after the weld is completed.
