Hot-wire consumable to provide self-lubricating weld or clad

摘要

A filler wire (consumable) for depositing self-lubricating materials in a system for any of brazing, cladding, building up, filling, hard-facing overlaying, welding, and joining applications. The filler wire is composed of a base filler material consistent with commonly known compositions. For example, the base filler material can comprise standard materials used in many standard mild steel wires. In addition to the base filler materials, the consumable includes self-lubricating materials. The self-lubricating materials include at least one of graphite particles and graphite powder, and can include other self-lubricating materials.
