Import Automatic Longitudinal Mig Welding Machines — Buy in wholesale FOB from Supplier in China

The Automatic Longitudinal MIG Welding Machine from Jinan Haoyu Automaton System Co. Ltd is designed for continuous longitudinal seam welding on cylindrical workpieces such as air tanks, water tanks, fuel tanks, and similar vessels. It handles steel, stainless steel, aluminium and copper, using a MIG process with a wire feeder, and is engineered for 24-hour operation. The machine integrates a Japan-sourced OMRON PLC with touch screen control, a water-cooling system, and a self-shielding welding system, alongside pneumatic clamping for precise workpiece positioning.

Constructed for heavy-duty use, the unit supports a maximum welding diameter of 2000 mm and a welding length of up to 2500 mm, with a welding speed of 700 mm per minute. The machine rapid speed reaches 2 m per minute, and it operates on a welding power source of 400A. Compatible with standard industrial power voltages of 220v, 380v, 415v, and 480v, it aligns with typical requirements for workshop environments. The design prioritises durability and repeatability, with typical industry expectations for MIG welders including consistent arc stability and minimal spatter.

This model is suited to manufacturers of pressure vessels, storage tanks, and custom metal fabrications where longitudinal seams demand high integrity. Buyers in automotive, aerospace, and industrial equipment sectors often specify such machinery for its ability to maintain tight tolerances over extended production runs. The inclusion of a servo-driven wire feeder and programmable logic control allows for adaptability across different material thicknesses and joint configurations, a feature valued in high-volume production lines.

Jinan Haoyu Automaton System Co. Ltd is based in Qihe Economic Development Zone, Shandong Province, China, with its factory located at Middle Mingjia Road. The company specialises in the design and manufacture of automated welding solutions, including longitudinal and circumferential welding machines for industrial applications. Its product range targets sectors requiring precision metal joining, such as pressure vessel fabrication and custom tank manufacturing.

The supplier operates within the Harbor trust tier, indicating a baseline level of verified business information. While the listing does not disclose response rate metrics, the company’s focus on automated welding systems suggests a commitment to industrial-grade equipment. The absence of additional details on certifications, client base, or production capacity means buyers should directly confirm these aspects with the supplier.
