Apprentice Tailor Jobs in Pittsburgh, PA (NOW HIRING)

For over 70 years, Tri-Arc Manufacturing has been offering state-of-the-art steel and aluminum rolling ladders and configurable platform products. Located just 20 minutes from downtown Pittsburgh, we proudly carry on Pittsburgh's industrial tradition by designing and building our products right here in the U.S. Tri-Arc is an industry leader, offering the widest variety and highest quality products, tailored to our customers' needs for safe and efficient operation.

Tri-Arc Manufacturing designs and builds custom steel and aluminum safety products, including safety ladders, rolling steps, work platforms, conveyor tables, and related industrial access and material-handling equipment. We serve customers who need durable, code-compliant equipment built to exact specifications, and our welders are central to delivering that quality.

The Welder II is a mid-level production welder capable of performing standard and moderately complex welding tasks on steel and aluminum components with limited supervision. This role builds on foundational welding skills, taking on a wider range of joint types, materials, and production jobs than an entry-level welder, while working toward greater independence and speed. Welder II team members follow established procedures, drawings, and work instructions, escalating unusual or highly complex jobs to a Welder III or supervisor.

Key Responsibilities

• Perform MIG (GMAW) welding on carbon steel and, with training, aluminum components for safety ladders, steps, platforms, conveyor tables, and related products.
• Read and interpret standard blueprints, weld symbols, and work orders to determine joint type and welding sequence, seeking guidance on complex or nonstandard drawings.
• Set up welding equipment (amperage, wire speed, gas flow) based on established parameters for common material types and thicknesses.
• Fit, tack, and weld components using jigs and fixtures to ensure proper alignment and dimensional accuracy.
• Weld standard joint types (butt, fillet, lap, corner) primarily in flat and horizontal positions; perform vertical and overhead welding with supervision or as trained.
• Visually inspect own welds for common defects (porosity, undercut, spatter) and perform basic grinding/cleanup; flag more serious defects to a lead or supervisor.
• Follow standard work instructions and quality checkpoints for assigned production jobs.
• Use precision measuring tools (tape measures, squares) to verify basic dimensional accuracy of completed work.
• Maintain a clean, organized, and safe work area; perform basic routine maintenance on welding equipment and report malfunctions.
• Accurately complete production paperwork, travelers, and basic quality documentation.
• Follow all company safety policies and use required PPE at all times.
• Assist Welder III staff or supervisors on larger or more complex jobs as assigned.

• 2–4 years of hands-on welding experience in a production or fabrication environment (or equivalent welding certificate program plus relevant experience).
• Solid proficiency in MIG welding on steel; basic aluminum welding experience or willingness to train.
• Ability to read and interpret standard blueprints and weld symbols.
• Ability to pass a welder qualification/skills test on company equipment (steel; aluminum a plus).
• Basic proficiency with measuring tools (tape measure, square) to verify dimensions.
• Good attention to detail and consistent, quality workmanship.
• Ability to follow written and verbal work instructions with moderate supervision.

Preferred Qualifications

• Formal welding training/certificate from a trade school or apprenticeship program.
• Experience in ladder, platform, mezzanine, or material-handling equipment fabrication, or other structural/metal fabrication settings.
• Familiarity with basic OSHA shop safety practices.
