GAS WELDER (MARKET COMPETITIVE)

The Gas Welder (BPS-04) serves as a skilled tradesperson within the public sector industrial establishment, responsible for fabricating, repairing, and maintaining metal structures, machinery parts, and pipeline systems using oxy-acetylene welding, brazing, and gas cutting processes. The role directly supports the operational readiness of production workshops, maintenance divisions, or training centers by executing permanent and repair joints on ferrous and non-ferrous metals according to engineering drawings and welding procedure specifications.

Daily workflow involves interpreting technical blueprints and welding symbols to determine joint design, material thickness, and required weld positions; setting up and calibrating oxy-acetylene equipment including regulators, hoses, torches, and flashback arrestors; selecting appropriate filler rods, fluxes, and nozzle sizes for specific base metals; performing fusion welding in flat, horizontal, vertical, and overhead positions; executing precision gas cutting and beveling operations; conducting visual and dimensional inspection of completed welds for defects such as porosity, undercut, or lack of fusion; and maintaining workshop tools, gas cylinders, and ventilation systems in compliance with the Factories Act and institutional safety SOPs.

Selection for this position is conducted exclusively through a practical trade test and oral viva voce; no written examination is administered. Candidates must demonstrate live proficiency in welding specified joints (fillet, butt, corner), brazing operations, and gas cutting tasks on test coupons within a timed workshop environment. The practical assessment is immediately followed by a technical interview evaluating metallurgical knowledge, equipment handling, safety protocols, and situational judgment relevant to industrial workshop operations.
