Morrow Welding Provides Reliable SAW Welding Machine Solution for Industrial Applications
In modern heavy industries, welding quality and production efficiency are very important. Large steel structures, pressure vessels, ships, and industrial equipment require stable welding equipment to ensure reliable welding results.
Recently, Morrow Welding supplied its SAW welding machine for a large Chinese enterprise. The machine has been used in practical industrial production and shows excellent performance in continuous welding applications.



The MZ7 Series of IGBT Inverter Submerged Welding Machine is developed for high-efficiency submerged arc welding. The system combines an advanced welding power source and an automatic submerged arc tractor to form a complete automatic welding solution. It can be used for butt joints, lap joints, and corner joints of middle and thick steel structures.
The SAW welding machine can weld different materials, including carbon steel, low alloy steel, stainless steel, and heat-resistant steel. It is suitable for many industrial fields where stable welding performance is required.
Advanced Technology Improves Welding Efficiency
The MZ7 Series uses soft switch technology, which provides high efficiency and energy-saving performance. The machine also has automatic protection functions, including over-current, overheat, and over/under-voltage protection. These functions help improve safety and extend the service life of the equipment.
The SAW welding machine supports multiple welding functions, including SAW, MMA, and gouging. It also adopts CC/CV technology, which allows welding with different wire sizes. The machine can support thin wire from 1.6-2.4mm and general welding wire from 3-5mm.

For different production requirements, the MZ7 series provides models from MZ7-1000 to MZ7-2000. The rated welding current covers 1000A, 1250A, 1600A, and 2000A with an 80% duty cycle. The machines can also achieve 100% duty cycle operation at lower rated current levels.
Stable Automatic Welding Performance
The automatic submerged arc tractor is an important part of the complete SAW welding machine system. The tractor has stable movement and a wide welding range. The welding wire diameter can reach Φ3.0-Φ6.0mm, which meets the needs of heavy steel structure welding.
The tractor design allows easy adjustment of the welding head, beam, and flux container. The wire feeding system uses an alignment structure to provide stable wire feeding, strong pulling force, and a wide adjustment range.
Because of these features, the SAW welding machine can help customers improve welding consistency and reduce manual operation difficulty.
Wide Application in Heavy Industries
The MZ7 Series SAW welding machine is widely used in industries such as boiler manufacturing, pressure containers, shipbuilding, steel structures, and petrochemical projects.
Morrow Welding Development LLC focuses on the research, production, and sales of welding power sources and welding equipment. Our products are widely used in steel, shipbuilding, oil, and smelting industries.
