One certified welding and mechanical contractor for the work that has to hold
Plant shutdowns, code-compliant welds and safe heavy lifts don’t leave room for improvisation. Tasweldermechanics is the regional welding and mechanical contractor industrial operators call when a job needs certified welders, structural steelwork, an in-house fabrication shop and the rigging to set it, delivered to standard.
Our Sint Maarten shop runs TIG, MIG, stick and flux-cored (GTAW, GMAW, SMAW and FCAW) welding stations, plate cutting and forming, pipe welding, a heavy-lift crane fleet and field crews that mobilize across the Leeward Islands and the wider Caribbean.

From enquiry to a documented handover
A clear path that keeps your project on standard and on schedule.
Scope & enquiry
You send the drawings or scope. We review the code, materials and feasibility, and come back with a quote.
Engineering & WPS
We confirm qualified welding procedures (WPS/PQR), verify mill certificates and material traceability, and plan the lift and weld sequence.
Fabrication & welding
Our in-house shop and field crews cut, fit and weld to AWS D1.1, ASME IX and API, with dimensional and heat-input control.
Delivery, install & inspection
We rig, lift and set the work, run visual inspection and NDT (dye penetrant, ultrasonic), and hand over full documentation.
Built to the standards your facility relies on
Industrial work is only as good as the code behind it. Ours follows the standards refineries and inspectors require.
For your procurement team: welder qualifications (WPS/PQR), certificate copies and safety documentation are available on request as an annex for vendor approval.
Our projects
Real fabrication and field work from our shop and job sites across the Caribbean.
Custom heavy-duty steel equipment base
Cut, fitted and welded from raw steel
A welded steel plate deck on a structural steel frame, engineered to carry heavy equipment. Cut, fitted, ground and welded from raw plate and sections by our crew in Sint Maarten, with AWS D1.1 welded joints, a typical example of the custom steel fabrication and mechanical work we deliver for industrial clients.

We’re based in Sint Maarten (SXM) and serve the wider Dutch Caribbean and Leeward Islands, mobilizing certified crews and equipment to Aruba, Curaçao, Bermuda and neighboring islands for each project.
Structural steelwork follows AWS D1.1, welder and procedure qualification (WPS/PQR) follows ASME Section IX, pressure vessels follow ASME Section VIII, and storage tanks follow API 650, API 620 and API 653.
Yes. We work with qualified WPS and PQR and support non-destructive testing (visual, dye penetrant and ultrasonic). Certificate copies, welder qualifications and safety documentation are available as an annex for vendor approval.
We mobilize welders, boilermakers, mechanical crews and rigging for shutdowns and turnarounds, working to the codes and safety procedures refineries and petrochemical plants require.
Yes. We fabricate and protect steel for the salt-air and corrosion conditions of the Caribbean, with marine-grade coatings, for terminals, docks and port structures.
Yes. Beyond full-scope contracting we work as a subcontractor to EPC and general contractors, and supply skilled labor and equipment with operators to reinforce your own crews.
Send us the scope, the applicable code and the timeline through our contact page, and we’ll quote it with the crews, procedures and equipment your job needs.
