Core Responsibilities

Primary Functions

Perform high-quality, X-ray grade welds on pipe and structural junctions using various processes, including Gas Tungsten Arc Welding (GTAW/TIG), Shielded Metal Arc Welding (SMAW/Stick), and Gas Metal Arc Welding (GMAW/MIG).
Interpret and work from complex engineering blueprints, isometric drawings, Piping and Instrumentation Diagrams (P&IDs), and detailed welding procedure specifications (WPS).
Set up and operate welding equipment, including power sources, wire feeders, and gas regulators, ensuring proper parameters (voltage, amperage, travel speed) for each specific task.
Prepare pipe and structural steel surfaces for welding by cleaning, grinding, beveling, and fitting components according to specifications.
Weld components in various positions, including flat, horizontal, vertical, and overhead (e.g., 2G, 5G, 6G), often in challenging field environments.
Execute precise root passes, hot passes, fill, and cap welds on a variety of materials such as carbon steel, stainless steel, and other alloys.
Conduct visual inspections of own welds to ensure they are free from defects like porosity, undercut, or lack of fusion, and meet quality standards before formal inspection.
Utilize hand and power tools safely and effectively, including grinders, buffers, cutting torches, and various measurement instruments.
Adhere strictly to all company and site-specific safety policies, including Lockout/Tagout (LOTO), confined space entry, and hot work permit procedures.
Maintain welding equipment and tools in good working order through routine cleaning, inspection, and preventative maintenance.
Select appropriate welding consumables, such as electrodes, filler wires, and shielding gases, based on the material and welding procedure.
Perform repairs on defective welds as identified by quality control inspectors, ensuring the final product meets all required codes and standards.
Collaborate closely with pipefitters to ensure proper alignment, gap, and fit-up of pipe spools and components prior to welding.
Work efficiently to meet project deadlines and production targets without compromising safety or quality.
Document completed welds and maintain accurate records for traceability and quality assurance purposes as required by the project.

Secondary Functions

Assist pipefitters and other trades in positioning, aligning, and securing components for welding.
Provide constructive feedback on welding procedures and suggest process improvements to enhance efficiency, quality, and safety.
Communicate effectively with foremen, supervisors, and quality control inspectors regarding job progress, material needs, and potential issues.
Participate actively in daily toolbox talks, pre-job safety briefings, and Job Hazard Analysis (JHA) reviews.
Mentor and provide guidance to apprentice welders and helpers, sharing knowledge of techniques and safety best practices.
Maintain a clean and organized work area to prevent hazards and promote an efficient workflow.
