Coating failure starts at the weld
Welds and heat-affected zones are structurally critical—and also among the most vulnerable areas to corrosion in steel assets.

Weak links in protection
Unlike flat steel surfaces, welds and heat-affected zones present unique challenges for conventional methods due to changes in metal microstructure, complex geometry, and residual stress. Improper treatment can lead to weak adhesion points in areas of stress concentration.
Welds don't need thicker coatings—they need stress-neutralizing surface preparation.
Unconventional geometric structures
Complex weld seam transition shapes and caps are difficult to access effectively with standard tools.
Welding Heat Affected
The oxides and residues generated during the welding process severely affect coating adhesion.
Residual stress
High-stress areas require neutralization treatment to prevent premature failure.
Channel restricted
Common narrow spaces and complex angles in steel structure welded joints.
Properly treat welds before coating
MontiPower supports a proactive approach, ensuring welds are properly treated before coating, reducing the risk of premature coating failure. The results are: stronger coating adhesion, more uniform thickness, fewer inspection findings, and longer coating service life. The Belt Selector matches abrasive belt types to weld geometry and rust grade; the ISO 8501-1 test report documents the achieved cleanliness level.
Dedicated Solutions for Weld Treatment
We combine various process technologies to precisely match the treatment requirements for welds and heat-affected zones—ensuring that surface cleanliness, anchor profile, and metallic integrity all meet standards.
Weld-specific geometric adaptability
The 11mm abrasive belt can work along the contour of the weld cap, processing the root of the weld and the edge of the heat-affected zone.
Oxide Removal
Remove weld oxides, spatter, and heat-affected zone residues to ensure reliable coating adhesion.
Stress neutralization treatment
No overheating, no work hardening—maintaining the metal integrity of the weld zone.
Files are traceable
ISO 8501-1 test reports record the cleanliness grades, meeting the coating inspection requirements.
Reliable coating adhesion
Ensure reliable coating adhesion in high-stress areas.
Corrosion risk reduction
Reduce the risk of under-coating corrosion.
Higher pass rate
Improve the pass rate and first-time pass rate of coating inspection.
Overall processing consistency
The treatment effect on the weld zone and the base metal zone is consistent.
Reduced whole life-cycle costs
Reduce whole-life maintenance costs.
