Combination Welder (Maint - No Per Diem)

Brown & Root Industrial Services, LLC•Chester, VA

12d

About The Position

The Combination Welder lays out, aligns, fits, and welds fabricated, cast, and forged components to assemble structural forms such as machinery frames, tanks, pressure vessels, furnace shells, buildings, and pipe according to blueprints and metallurgy. The role requires proficiency in SMAW, GTAW, and GMAW processes and may require x-ray-quality welds. The welder must perform only procedures for which they are certified and may be required to pass employer performance or standard tests to meet certification standards. The position works under immediate supervision and relies on instructions and pre-established guidelines. Primary job functions typically do not require independent judgment, and the role reports to a supervisor or manager. Work involves selecting materials, equipment, and welding methods; positioning and joining components; operating welding equipment; inspecting welds; handling materials and tools; and performing minor equipment maintenance. Respiratory protection is common and may be required. Physical requirements include standing 50% of the time, walking 20%, sitting 30%, and lifting and carrying up to 35 pounds. Reaching, handling, and fingering are constant requirements; climbing, balancing, stooping, kneeling, crouching, and crawling are occasional.
