State two applications of the welding processes used to train pipeline welders.

1. Construction of pipelines: Pipeline welders are trained in welding processes such as shielded metal arc welding (SMAW) and gas tungsten arc welding (GTAW) to construct pipelines for transporting oil, gas, water, and other fluids. These welders are responsible for joining sections of pipe together to create a continuous pipeline that is strong, durable, and leak-proof.

2. Repair and maintenance of pipelines: Pipeline welders are also trained in welding processes to repair and maintain existing pipelines. They may need to cut out damaged sections of pipe and weld in new sections, or repair leaks and cracks in the pipeline. These welders play a crucial role in ensuring the safe and efficient operation of pipelines.

1. Oil and Gas Pipelines: Welding is crucial in constructing and repairing pipelines used to transport oil and gas. Skilled welders are needed to create strong, leak-proof joints that can withstand high pressure and temperature.
2. Water and Wastewater Pipelines: Welding is also used extensively in the construction of water and wastewater pipelines. These pipelines require corrosion-resistant welded joints to ensure the safety and integrity of the system.
