About Smart Welding

Smart Welding is located in the municipality of Macaé-RJ, considered the National Capital of Brazilian Petroleum. We occupy an installation at Parque Lagomar with innovative technologies and intelligent solutions in welding and CNC processes.
We use state-of-the-art and precision technology, seeking to reduce execution time and guarantee efficiency in the application of resources and quality of services, being effective in our clients' results, reducing time losses and failure rates during project execution.
Our work processes serve companies from oil & gas (on / off-shore), shipbuilding, power, tube machining, power generators, piping lines to simple repair and maintenance services.

Main Services Automated Welding

Cladding

Refers to a process in which a metal, resistant to corrosion or composite (coating material) is electrically connected, or mechanically through some process of high pressure and temperature to another metal (the substrate) to increase its durability, resistance or appearance or just return to original dimensions and sealing. The cladding weld is usually between 2 and 20 mm thick. It can be applied using a variety of welding processes where SMART Welding is able to perform, including TIG (GTAW), Mig / Mag (GMAW), submerged arc (SAW) and plasma welding (PTAW) welding processes.

Stub-Welding

After repairs and successive cutouts, important drilling tools may not meet acceptable inspection standards, rendering them unfit. Following detailed procedures and techniques, stub-welding allows a "lost" material to return the tool and bring it back to the original specifications and make them fit for service again.

Hardbanding

The result of significant savings in downtime and production costs has meant that this process has been adopted in a number of industries, including steel, cement, mining, petrochemicals, energy, sugar cane and food. Especially in the oil and gas sector are more common to fix redress stabilizer and hardbanding riser due to the need to stabilize BHA during drilling or reduce aggressive damage in tools. The process can be T2A flamespaving or PTA and brazing process (H300 and Cotraite).

It is a process where a consumable solid wire is fed through a conduit and a torch to the arc of weld where it melts and is transferred in the form of droplets to form the weld metal.

The arc and the puddle are protected by shielding gas, usually argon, CO2 or a mixture of these. The choice of gas depends on the material to be welded.

 
It is a mechanized process where one or more wires are fed through a conduit and a contact tip up to the welding arc. Solid wires are mainly used, but certain tubular types are also developed for this process. The arc and the melting puddle are protected by a mineral flow supplied in front of the wire, this melting creates a slag that also contributes to a particularly smooth surface.

(Transfer Arc Plasma) is a developed TIG welding technique, with the arc surrounded by a concentrated

gas flow supplied at high pressure through a central tube. In this way, the gas, usually argon, is ionized to create a plasma arc column with high energy and temperature.

  
It is used where high deposition rates combined with high quality are required. The wire is preheated electrically and enters the melt pool. The system can be used for the coating or bonding of ferrous and non-ferrous alloys.
Weld Head for Multi Pass Weldig: Suitable for all passes: Rot, Hot, Fill and Cap Precision tool for perfect repeatable welds. The Orbital Technical Welding System is designed to make tube-to-tube and pipe-to-socket welds. Interchangeable track rings guide the head around the tube, allowing a wide range of parts sizes from 3 ".The Welbug system improves productivity by increasing duty cycle, reducing repair rates to below 0.1% and consistency in the production of quality welds.
