Import Automatic Straight Seam Welding Machine — Buy in Bulk from Supplier in China

The Automatic Straight Seam Welding Machine from Guangzhou Duro Welder Ltd. is a two-part system combining a custom straight seam automatic machinery unit with a standard welding source. Models range from SSW-300 to SSW-2000, with input voltages of 220V, 380V, 440V, or 480V at 50/60Hz, and maximum welding lengths from 320mm to 2000mm. The machinery part can be configured with either a plate type pressing mechanism or a keyboard type copper pressing mechanism to ensure stable clamping and cooling for different materials.

Designed for stainless steel, iron, aluminum, and brass, the system supports TIG, MIG, MAG, SAW, and PAW welding processes. Workpiece diameters span 48-960mm, while thicknesses range from 0.3-3mm depending on the model. The PLC-controlled DC motor drive allows stepless speed adjustment between 300-2000mm/min. A weld seam backup design with a groove ensures consistent gas flow, enabling double-side forming in single-side welding, a critical feature for metallic cylinders and aligned plates.

This machine is used primarily in industries requiring high-efficiency, low-distortion straight seam welding, such as pressure vessel fabrication, pipe manufacturing, and sheet metal assembly. Buyers typically include metalworking shops, industrial equipment manufacturers, and fabrication plants. The system’s compatibility with third-party welding power sources adds flexibility, while its automated design reduces manual labor and improves weld consistency compared to traditional methods.

Guangzhou Duro Welder Ltd. operates from Deli Industrial Park in Hu Town, Boluo County, Huizhou City, Guangdong Province, China. The company specializes in welding machinery, with a focus on automated solutions for industrial applications. Its harbor-tier trust status reflects a verified operational presence, though its response rate and average response time are currently listed as zero, indicating limited or unrecorded communication activity on the platform.

The supplier’s product line includes straight seam welding machines designed for precision and efficiency, catering to industries like metal fabrication and pressure vessel manufacturing. While the profile does not disclose certifications, production scale, or client base, the technical specifications provided for its machines suggest a focus on customizable, high-performance equipment. Buyers are advised to confirm verification details, production capabilities, and after-sales support directly with the supplier.
