Welding and Pipe-fitting in Brazil's Energy Sector

It's my job. There's a big oil and gas industry in Brazil. We also produce a lot of ethanol, so I'm always busy! Most metal pipes and fittings are welded. This means that pipe-fitters and welders work closely together.

Finally, workers paint and... Continue reading "Welding Safety and Pipe-fitting in Brazil's Energy Sector" »

However, the patrol boats were not as fast as the smugglers’ speedboats. During the operation, two sergeants from the Guardia Civil specialized in organized crime tragically lost their lives.

Finally, thanks to witness statements, officers identified and arrested the suspects.... Continue reading "Guardia Civil Operations and Road Safety Reports" »
