Introduction
In today’s times of reduced manual labor onboard vessels coupled with the increasing challenges to perform maintenance tasks of equipment under tight schedules, the staff that occupies a ship must be trained in the required skills to carry out safe, efficient, and quick repair of cracked, damaged or leaking plates and pipes.
Why are there so many requirements for the marine industry and how does this “Marine Shipyard Welding and Fabrication Certification” course contribute to those? Marine welding roles require a vast array of skills and training due to the safety considerations involved in the marine industry. Failure to keep your work up to standards can not only result in monetary penalties but also jeopardize the workers and anyone else whose work depends on the structural integrity of the vessels and equipment that they operate with. This program acquaints its participants with the relevant safety precautions to be observed, the requisite knowledge of the various welding equipment, and processes. It also identifies proper electrode and welding parameters for selection, and the practical skills required to execute various repair jobs on plates and pipes.
This Xcelerate Training Institute course will empower you with the importance of attention to detail, stamina, and a high degree of technical skill when it comes to marine shipyard welding and fabrication.
