Job Description
Position Summary:
\n
We are seeking a skilled and safety-conscious Copper Brazing Technician to join our manufacturing team. This role is responsible for performing precision brazing of copper components, interpreting blueprints, operating torches (Oxygen/Acetylene), and ensuring high-quality standards in product assembly. The technician will follow controlled brazing procedures/work instructions, maintain required documentation/traceability, and support leak/pressure testing and rework verification as part of production builds.
\n
Key Responsibilities:
\n
- \n
- Join copper components by heating them and applying filler metal to create strong, leak-proof bonds.
- Interpret blueprints and written instructions to ensure accurate assembly and placement of copper parts.
- Operate single- and dual-tip torches safely and effectively, maintaining precise heat control throughout the brazing process.
- Clean, prepare, and assemble copper pipes and fittings prior to brazing.
- Follow strict safety procedures, including proper handling of compressed gases and maintaining a safe, organized workspace.
- Operate and monitor brazing furnaces and other related equipment as needed to support production.
- Assist with basic equipment maintenance and promote good housekeeping practices in your work area.
- Apply fluxing techniques to chemically remove oxides, provide a protective barrier against atmospheric gases, and facilitate the flow and wetting of filler metals.
- Monitor joint temperature visually during brazing.
- Utilize induction heating as an alternative method when appropriate.
- Follow documented brazing procedures/work instructions, complete travelers, and record in-process/finish inspection results.
- Maintain cleanliness of tubing/lines (cap/plug open lines as required) and prevent contamination/foreign material during assembly.
- Set up and perform dry nitrogen purge during brazing when required to minimize internal oxidation/scale and maintain internal cleanliness.
- Select and use appropriate filler metals, fluxes, and joint configurations based on drawings/specifications and approved processes.
- Support pressure/leak testing per specification; troubleshoot leaks/defects, perform approved rework, and verify repair effectiveness.
- Troubleshoot brazing defects (e.g., porosity, lack of fill, overheating, pinholes) and support root-cause/corrective action with Quality/Engineering.
- Use approved temperature indicators and measurement tools (e.g., temperature crayons/IR thermometer/fixtures) when required to ensure repeatable joints.
- Comply with site hot-work controls (e.g., hot-work permits, ventilation, and fire-watch requirements) as applicable.
