TuffStudds Wear Protection System

TuffStudds Superb wear and abrasion protection for material handling plants and earth moving equipment.

TuffStudds are chromium carbide-laden, wear-resistant alloy studs that are readily applied onto alloy castings or plate. The applied pattern becomes embedded with mineral debris, causing a dead bed effect over 70% of the area, which enhances wear protection.

TuffStudds reduces costs in many ways, including less downtime, reduced labor for maintenance and lower overall cost of component replacement.

How are TuffStudds applied?

TuffStudds are applied using a stud welding system that employs a stud gun powered by a transformer/rectifier with solid state weld timing and amperage control. For field applications requiring maximum portability, an AC generator with a minimum capacity of 85 kW can power the DC welding system. Each TuffStudd takes only 0.6 to 1.2 seconds of arc time to apply. Simply load a TuffStudd and a ceramic arc shield (ferrule) into the stud welding gun, position on the work surface and pull the trigger.3

The arc stud welding process

A TuffStudd is positioned in contact with the work surface. 1) A TuffStudd is positioned in contact with the work surface.

The welding gun trigger is pulled, initiating the welding arc and automatically lifting the stud.2) The welding gun trigger is pulled, initiating the welding arc and automatically lifting the stud.

The main welding current melts a portion of the stud and the work surface. Within a second, the Tuffstudd is plunged into the molten pool.3) The main welding current melts a portion of the stud and the work surface. Within a second, the Tuffstudd is plunged into the molten pool.

The ceramic arc shield (ferrule) retains the molten metal in the weld area for maximum strength and safety, and the Tuffstudd is metallurgically bonded to the work surface at the weld interface.4) The ceramic arc shield (ferrule) retains the molten metal in the weld area for maximum strength and safety, and the Tuffstudd is metallurgically bonded to the work surface at the weld interface.
