Lawrence Berkeley National Lab’s (LBNL) Engineering Division has an opening for a Welder/Fabricator to join the team.

In this role, you will be working as a Welder in the Mechanical Engineering Division, under general supervision, perform complex and specialized welding and  fabrication assignments using both common and uncommon, materials, techniques and processes in the layout, forming, welding, fabrication, testing and installation of laboratory scientific components, assemblies, equipment and systems.

 

What You Will Do:

  • Under general supervision, apply technical skills and abilities for the welding and fabrication of a wide array of components, many of which will see service in a High or Ultra High Vacuum environment. Working from verbal instructions, blueprints, sketches, and CAD data, complete unique assignments involving precision fabrication, welding, installation, test, repair, and modification of laboratory scientific components, assemblies, equipment and systems, while utilizing both common and uncommon materials, techniques and processes.
  • Primarily employ GMAW and GTAW welding processes as appropriate for the task at hand. Other processes, such as SMAW and TIG Brazing may also be used.
  • Use of metal cutting and forming machinery, such as brakes, shears, punch presses, and possibly waterjet and/or laser cutting machines.
  • Use computers, in conjunction with Computer Aided Design/Computer Aided Manufacturing software applications to:
    1. Access, view, import, export, measure, manipulate and construct native electronic drawings and solid models as well as generic file formats such as dxf and iges. 
    2. Apply appropriate and efficient tool/cutter path to geometry, proper machining sequences, and federates.
    3. Generate, edit and transfer appropriate machine tool controller-specific part program instructions.
  • Decode blueprints, sketches, parts lists, and assembly diagrams. 
  • Apply Geometric Dimensioning and Tolerancing standards to aid manufacturing processes, including:
    1. Comparing Datum Reference Frames to Datum Features for correct decoding.
    2. Decoding the symbols and terminology describing part feature form, size location, orientation, surface finish and welding data.

 

What is Required:

  • Journey-level knowledge, skills and abilities in welding, fabrication, and related mechanical processes theory and work practices.
  • Ability to independently select, program as required, set-up and operate appropriate hand, power, and specialized tools of the sheet metal and welding trades including forming, fabricating, shape-cutting and welding machines in the manufacture of specialized and unique scientific components, assemblies, equipment and systems.
  • Extensive knowledge, skill and work experience in performing highly complex layouts, set-ups and forming and joining operations in the precision fabrication of extremely close-tolerance scientific components, assemblies, equipment and systems while utilizing uncommon materials including but not limited to tantalum, titanium, molybdenum, copper, Inconel, tungsten, aluminum, steel and stainless steel metals and alloys.
  • Ability to design, fabricate, modify and implement unusual and unique fixturing strategies, systems and techniques.
  • Ability to perform High and Ultra High Vacuum welding operations utilizing both common and uncommon materials, equipment, techniques and processes while maintaining joint leak rates as low as 1X10-9 Atm. cc/sec, helium, or better.
  • Ability to independently accomplish highly complex assignments involving high-value laboratory scientific components, assemblies, equipment and systems of unusual and unique design, by exercising independent judgment and following supervision guidance essentially limited to general assignment parameters, budgets, and timelines.
  • Ability to read and correctly decode blueprints, sketches, parts lists, layout and assembly drawings and operation, calibration and repair manuals.
  • Ability to climb stairs and ladders, work from heights and confined spaces, and lift 23 kg (50 lbs). 
  • General personal computer application skills with spreadsheets, databases and word processors and other business applications.
  • Possess a valid current driver's license.

 

Desired Qualifications:

  • An equivalent to an AA degree in Mechanical Engineering Technology, successful completion of formal Welder and/or Sheet Metal Worker apprenticeship program(s), or the equivalent in formal industrial or military training and industry equivalent experience is preferred.
  • Experience in glove-box welding techniques on Ultra-High Vacuum components, composed of common and/or uncommon materials, with resulting leak rates of 1X10-9 Atm. cc/sec, helium, or better.
  • Ability to view, modify and create electronic CAD/CAM data for use in both design and manufacturing.
  • Certified in ASME Y14.5M Geometric Dimensioning and Tolerancing.

 

Notes:

  • This is a full-time career appointment, non-exempt (hourly paid) from overtime pay.
  • This position is represented by a union for collective bargaining purposes.
  • Salary will be predetermined based on collective bargaining agreements set rates.
  • This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
  • Work will be primarily performed at Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.
