AI Technical Summary
During the submerged arc additive manufacturing process, as the printing height increases, the flux lacks support on both sides during the laying process, making it difficult to cover the melt pool, resulting in a decrease in forming efficiency.
A fence is designed with a simple structure and good assembly ability, including a bottom support and a side circumference. A runner is arranged inside the bottom support for cooling. A magnetic suction piece is provided on the front side of the bottom support for adsorption on the side wall of the workpiece, and a guide plate and a guide notch are provided at the upper end of the bottom support to achieve linear assembly and turning.
The cooling efficiency of the fence is improved through the cooling runner, the magnetic suction member ensures the firm adsorption of the fence, and the guide structure realizes linear assembly and bending, which improves the forming efficiency and welding quality of submerged arc additive manufacturing.
