Description

Technical Field

[0001] The utility model belongs to the technical field of marine engineering, and in particular relates to a pipeline welding device used in marine engineering. Background Art

[0002] Offshore pipelines are widely used to transport energy sources such as oil and natural gas. To ensure the safety and efficiency of the transported media, high-quality welding is required at the pipeline joints. Pipeline welding in marine environments often presents numerous challenges due to the unique working conditions. This is particularly true during full welds, where the weld seam must be complete and continuous to avoid leaks. Traditional welding methods typically involve placing the pipeline on the ground and securing it with spot welds, followed by welding along the outer circumference of the pipeline using a welding torch. However, this method has several drawbacks: When the pipeline is laid flat on the ground, the bottom of the pipeline contacts the ground, making it impossible to weld directly. The pipeline must be rotated regularly to complete the weld, which increases the difficulty and reduces welding efficiency. Welding the pipeline upright increases the risk of working at height and is prone to tipping over when the pipeline is long, requiring additional support structures. Some welding equipment uses motors to adapt to pipes of varying diameters. While this method allows for automated adjustment, the equipment is bulky and heavy, making it difficult to move and expensive. Utility Model Content
