In stud welding, the welding gun is the link between the power source and the fastener, and its configuration has a direct impact on how consistently the welding cycle is applied. Choosing the right arc stud welding gun requires consideration of the welding machine, stud diameter, fastener geometry, access to the welding area and the conditions in which the equipment will be used.
Different gun configurations are available for the main drawn arc and short arc welding processes. For drawn arc applications, the gun can be configured for use with a ceramic ferrule, which contains and protects the weld pool during the cycle. Where the process uses inert gas shielding, the gun can instead be equipped for the required gas protection around the welding area.
The fastener itself also influences the choice of equipment. Threaded studs, internally threaded bushes, plain studs and other weldable fasteners may require specific components or accessories depending on their dimensions, shape and positioning. Matching the gun correctly to the fastener helps maintain stable operating conditions and consistent welding results.
Stud welding guns can be used for manual operations or incorporated into production systems with different levels of automation. This is particularly relevant when welding points are difficult to reach, when the same operation must be repeated across a series of components, or when different fastener sizes need to be handled within the production process.
A.T.S. supplies welding guns for short arc and drawn arc stud welding and provides technical support to manufacturers, fabricators and engineering departments. The selection takes into account the welding machine, process, fastener, diameter, material and operating conditions, helping identify a gun and configuration suited to the actual application rather than simply selecting a standard accessory.
