Core Responsibilities

Primary Functions

Accurately interpret complex engineering blueprints, schematics, and work orders to determine assembly sequences and component requirements for each project.
Expertly set up and operate MIG (Metal Inert Gas) welding equipment to join, fabricate, and repair metal components with precision and structural integrity.
Skillfully utilize a wide variety of hand tools, including grinders, drills, and deburring tools, to prepare and finish parts for the assembly process.
Operate power tools and stationary machinery such as hydraulic presses, benders, and cutting saws to shape and size materials according to specifications.
Meticulously load and position components into specialized fixtures and jigs, ensuring proper alignment and fit-up before welding or fastening.
Perform visual and dimensional inspections on raw materials, in-process sub-assemblies, and finished products using calipers, gauges, and other measuring devices to ensure they meet strict quality standards.
Execute tack welding and final welding passes on assemblies, controlling heat and distortion to maintain dimensional accuracy and avoid material defects.
Systematically troubleshoot and diagnose issues with assemblies, identifying root causes for non-conformance and performing necessary rework or repairs.
Adhere rigorously to all company safety protocols and procedures, including the proper use of Personal Protective Equipment (PPE) like welding helmets, gloves, and safety glasses.
Maintain a clean, organized, and safe work area by following 5S principles and participating in regular housekeeping activities.
Monitor welding equipment and machinery for proper function, performing basic operator-level preventative maintenance and reporting any malfunctions to the maintenance team.
Document production and quality data accurately, completing all required logs, forms, and traceability records for each completed assembly.
Collaborate effectively with team members, supervisors, and quality personnel to coordinate workflow and ensure production targets are met efficiently.
Handle and transport materials, components, and finished assemblies within the production area, utilizing carts or pallet jacks as needed.
Actively participate in continuous improvement initiatives by providing constructive feedback on processes, tooling, and workflow to enhance safety, quality, and productivity.
Manage the flow of components at the workstation, ensuring all necessary parts are available and organized to support an uninterrupted assembly process.
Conduct pressure or leak testing on sealed assemblies to verify the integrity and quality of weld seams and joints.
Adjust machine settings, such as wire speed and voltage on welders, to match the specific requirements of the material and application.
Identify and tag non-conforming parts or defective materials, segregating them according to quality control procedures to prevent their use in production.
Train and mentor new or less-experienced assemblers on standard operating procedures, safety guidelines, and quality expectations.
Cross-train on different assembly stations and product lines to provide operational flexibility and support overall team goals.

Secondary Functions

Assist with periodic inventory counts and material tracking to support the production planning and logistics teams.
Provide practical feedback on assembly processes and suggest design-for-manufacturability improvements to the engineering team.
Work closely with Quality Assurance and Engineering teams to investigate product non-conformities and help implement effective corrective actions.
Engage in daily team huddles, shift-change meetings, and continuous improvement events to discuss production targets, safety topics, and operational challenges.
