Problems solved by technology

However, for the lap welding of socket pipes, since the welding structure itself requires sufficient welding area to ensure the overall strength and mechanical properties of socket joints, single-pass laser welding cannot meet the requirements, and multiple passes of surfacing welding are required, which makes the process cumbersome , cost increases, limiting the application of laser welding in this field
