METAL WELDER (MARKET COMPETITIVE)

The Metal Welder (BPS-04) serves as a skilled tradesperson within the public sector industrial establishment, responsible for fabricating, repairing, and maintaining metal structures, machinery components, and pipeline systems essential for government infrastructure and production operations. The role demands expert execution of various welding processes including Shielded Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW), and Oxy-Acetylene welding to meet stringent structural integrity standards. Appointees work under the supervision of a Workshop Foreman or Assistant Engineer, contributing directly to the operational readiness of heavy mechanical workshops, industrial training centers, or public sector manufacturing units.

Daily workflow involves interpreting engineering drawings and welding procedure specifications (WPS) to determine joint design, electrode selection, and welding parameters. The welder sets up and calibrates welding machines, prepares base metals through cutting, beveling, and cleaning, and executes welds in flat (1G), horizontal (2G), vertical (3G), and overhead (4G) positions. Post-welding duties include visual inspection for defects like porosity, undercut, and slag inclusion, grinding and finishing weld beads, and performing basic preventive maintenance on welding rectifiers, transformers, and gas regulators. Work is recorded in job cards and welding logs adhering to Pakistan Engineering Council (PEC) and relevant ISO 3834 quality standards.

Selection for this Category B position is conducted strictly through a Practical Skill/Trade Test and a Direct Interview (Viva Voce); no written examination is administered. Candidates are evaluated on a live welding demonstration where they must produce test coupons in specified positions and processes for destructive (bend test) or non-destructive visual assessment. The oral viva voce assesses technical knowledge of metallurgy, welding symbols, safety codes (OSHA/Pakistan Factory Rules), and situational problem-solving on the shop floor. Final merit is determined solely by the combined aggregate of the practical test and interview marks.
