Tuffstudds

How TuffStudds work

01.Pattern coverage

Tuffstudds are stud welded across roughly 30% of the metal surface, leaving engineered gaps.

Material debris settling into the gaps between TuffStudds during operation

02.Material trapping

Mineral debris accumulates and settles into these open spaces during operation.

A protective dead bed of trapped material formed over the base metal

03.The "dead bed" effect

Trapped material forms a stagnant layer (the dead bed) over 70% of the area, allowing material to wear on itself.

Proven TuffStudd outcomes

80%Cost reduction

Saved $67,000 per CAT 815 Compactor over 4 years by eliminating cap replacements and hard-facing labor.

TuffStudds vs.

Weight

Moderate

Sits between hardfacing and wear plates at 30.0 kg/m², requiring only ~30% surface coverage to create a "dead bed" effect

Low

A thin overlay on high wear zones offers little alloy to last under heavy abrasion

Durability

High

Lasts up to 3x longer than conventional hardfacing

Moderate

Solid protection, but subject to rapid washing out under extreme sliding abrasion

Deposit efficiency

High · 100%

Studs welded with near-zero material waste

Low · 60-70%

High spatter, slag creation, and stub loss during manual stick or wire welding

Sustainability

High

Near-zero material waste

Low

30-40% material waste

Heat input

Low

0.6–1.2s arc time per weld cycle delivers minimal heat, minimizing base metal stress

High

Extended arc time transfers massive thermal energy, causing base metal stress, warping, and cracking

Positional capability

High

Applicable in all welding positions: flat, horizontal, vertical, and overhead

High

Applicable in most welding positions with a skilled operator

Labour needs

Low

Applied using stud welding, a very low-skill process

High

Requires skilled welders throughout the application

Downtime

Low

Ultra-fast application (up to 0.40 m²/hr) with localized repair allows rapid return to service

High

Application and cooling cycles keep equipment out of service for extended periods

Reapplication effort

Low

New studs are restudded on top or in between old worn-out studs

High

Buildup, dilution, and base metal stress complicate repeat overlays
