Where Coating Failure Begins
Weld seams and heat-affected zones are structurally critical, and among the most corrosion-prone locations on steel assets.
The weak link in protection
Unlike flat steel, weld seams and HAZ present unique challenges. Changes in metallurgy, geometry, and residual stress make them especially vulnerable when prepared inadequately.
“Weld seams don't need thicker coatings, they need stress-neutral preparation.”
Irregular geometry
Complex transitions and weld caps that standard tools struggle to follow.
Metallurgical changes
Oxides and residues from the welding process that compromise adhesion.
Residual stress
Higher-stress zones that require neutral preparation to prevent damage.
Access constraints
Tight spaces and difficult angles common in structural steel.
Prepare weld seams before coating
MontiPower supports a preventive approach, ensuring weld seams are prepared correctly before coating, reducing the risk of premature failure. The result: improved adhesion, fewer callbacks, and longer coating life at the most vulnerable points on the asset. The Bristle Blaster® conditions seam and HAZ in one pass, part of in-service surface preparation.
