General Information & Industry Insights To broaden the knowledge of anyone reading this recruitment notification: Understanding Welding Positions (3G vs. 6G): In structural and pipe fabrication, welding certifications are categorized by position difficulty. A 3G certification covers vertical groove welding on flat plates. A 6G certification is the most rigorous standard—it involves welding a pipe fixed at a 45-degree angle without rotating it. A certified 6G welder is qualified to weld in all positions (1G, 2G, 3G, 4G, 5G, and 6G) and is highly sought after for high-pressure industrial piping and gas lines. Role of Chargehands and Leadmen in Construction: In MEP contracting, a Chargehand or Leadman serves as the primary liaison between project engineers and frontline trade workers. They directly oversee small teams (6 to 15 workers), ensuring daily output targets are met safely and according to technical shop drawings. The Significance of Local Visa Transfers (QID): In GCC countries like Qatar, hiring locally via transferable visa (NOC) allows engineering firms to onboard workers immediately without waiting for overseas recruitment cycles, medical checks, or embassy visa processing. For workers already in Qatar, it offers a seamless path to transition to new commercial projects.
