High-Quality HRWS Precision Repair Welding Machine Supplier, Factories

Small heat affected zone. No need for preheating treatment, no annealing of the workpiece after welding. No deformation and collapsed edge. No porosity and sand holes. Accurate and precise welding of small and precise geometrical zones with the finest wires up to 0.1-0.2 mm, easy to use and flexible, direct on-site repair, eliminating the need for costly separation of the workpiece or repair part. It can be used to repair cracks, chips, corners, sand holes and after wear and tear.

Product Description

Small heat-affected zone (HAZ).
No deformation, no edge collapse, no pores, and no sand holes.
High precision and accuracy — capable of welding any fine geometric area; the thinnest welding wire available is 0.1–0.2 mm.
Easy and flexible to use; on-site repair is possible, eliminating the need for costly disassembly of workpieces or repair sections.
Applicable for repairing cracks, chipping, edges, blowholes, and wear damage. It can also be used for re-welding workpieces after EDM, nitriding, or soft nitriding treatment.
Strong bonding strength; suitable for various machining processes without issues such as poor adhesion or peeling.
Capable of efficient, low-temperature precision repair welding over large areas.
By using materials of different hardness, various post-weld hardness levels (e.g., up to HRC 60°) can be achieved.
Frequently Asked Questions
What are the main benefits of this welding technology?
The main advantages include a small heat-affected zone (HAZ), no deformation, and no pores. It offers high precision for fine geometric areas and is flexible enough for on-site repairs.
Can it be used for very thin or fine welding repairs?
Yes, it is highly accurate and capable of welding fine areas. The system can utilize welding wires as thin as 0.1–0.2 mm for precision work.
Is it necessary to disassemble workpieces for repair?
No, the equipment is designed for easy and flexible use, allowing for on-site repairs which eliminates the need for expensive disassembly of sections or workpieces.
What kind of defects can be repaired with this method?
It is ideal for repairing cracks, chipping, edges, blowholes, and wear damage. It is also suitable for workpieces that have undergone EDM, nitriding, or soft nitriding treatments.
