Coded Welder Supply in Singapore — ASME, AWS and WPQ Certified Welders for Process Piping and Structural Works
Sending an uncertified welder to an oil and gas piping weld is one of the most costly mistakes on any plant project — failed welds discovered during inspection result in costly rework, schedule delays, and serious safety risk. We supply ASME B31.3 and AWS certified coded welders whose Weld Procedure Qualification (WPQ) certificates are verified against your project’s welding procedure specifications before every deployment — ensuring every weld is carried out by a qualified welder with the right certification for your specific weld joint.
We supply coded welders across all main welding processes and positions required in Singapore’s oil and gas sector. ASME B31.3 process pipe welders for carbon steel, stainless steel, and alloy process piping on petrochemical plants — 1G, 2G, 5G, and 6G position qualified. AWS structural welders for structural steel connections, equipment supports, and skid fabrication requiring AWS D1.1 certification. 3G and 4G position welders for vertical and overhead position structural welding on plant structures and equipment. And TIG welders for root pass welding on stainless steel and high-alloy piping where weld quality is critical.
Coded welders on Jurong Island and oil and gas plant sites work alongside a coordinated multi-skill crew. Our pipe fitters fit up piping spools for your coded welders before and after the weld. Our E&I technicians carry out the electrical and instrumentation works around the piping your welders complete. For crane-assisted positioning of pipe spools and equipment, our rigger man and signal man lifting teams are PTW-experienced. For plant shutdown TAR programmes, our shutdown workers provide complete multi-skill crews. For WSH safety appointments on your site, our WSHO officers and ECO officers cover all statutory appointments.
Our coded welder supply covers all project types — from a single coded welder for a specific weld procedure to a full welding crew for a large-scale piping project or plant turnaround. Every WPQ certificate is checked against your project’s welding procedure specifications before deployment. We are the employer of record — managing all work permits, levies, and insurance. Your welding engineer or QC inspector directs the welders on site. For the full oil and gas plant workforce, our oil and gas manpower supply covers all plant worker types. For structural fabrication welding alongside process piping work, our welder manpower supply service covers the full welding workforce. For urgent welding requirements, our temporary staffing deploys additional certified welders within 24 to 48 hours.
Coded welders for oil and gas process piping in Singapore must hold Weld Procedure Qualification (WPQ) certificates issued under ASME B31.3 for their specific weld process and position. For structural welding, AWS D1.1 certification is required. We verify every welder’s WPQ certificates against your project’s welding procedure specifications before deployment.
We supply coded welders for SMAW, TIG (GTAW), and MIG (GMAW) welding processes. Position qualifications available include 1G, 2G, 5G, and 6G for pipe welding and 1F through 4F and 3G/4G for structural welding. Tell us your WPS requirements and we match the correct WPQ certification.
We respond within 1 business hour. WPQ certificate verification against your welding procedure specifications typically requires 24 to 48 hours. For planned projects and TAR programmes, 5 to 7 days advance engagement is recommended for optimal welder-to-WPS matching.
Yes. We supply coded welder crews for planned plant shutdowns and turnaround programmes across Singapore including Jurong Island facilities. For TAR welding programmes, we recommend early engagement of 2 to 3 weeks to assemble and certificate-verify the full welding crew for your specific WPS requirements.
Yes. We supply coded welders with hands-on experience at Jurong Island petrochemical and process plant facilities — familiar with PTW systems, confined space welding procedures, hot work permit requirements, and plant-specific safety protocols.
