Overview

What is additive welding?

Metal Build-Up

Add material precisely where needed to rebuild worn zones or create new features.

Repair-Oriented Manufacturing

Ideal for shafts, dies, molds, and heavy components where replacement is expensive.

Hybrid Manufacturing

Combine additive welding with machining for near-net-shape components.

Applications

Where additive welding is used

Typical Components

  • Shafts, rollers & journals
  • Dies, molds & tooling repairs
  • Flanges & sealing surfaces
  • Heavy machine components

Industries

  • Automotive & heavy engineering
  • Power & process industries
  • Mining, cement & steel plants
  • Oil & gas maintenance
Process

Additive welding workflow

Feasibility Study

Review component geometry, base material, target build height, and service conditions.

Planning & Setup

Define deposition strategy, bead overlap, heat control, and robot path planning.

Layer Deposition

Execute controlled welding passes with consistent geometry and minimal dilution.

Finishing & Validation

Post-weld inspection, machining allowance check, and dimensional validation.

FAQ

Common questions

No. Additive welding uses welding processes for metal deposition and is best for large, repair-focused, or heavy components.
Carbon steel, stainless steel, nickel alloys, hardfacing alloys, and application-specific wires.
Usually yes, for dimensional accuracy and surface finish, depending on tolerance requirements.
