Our DJJ series shearing and butt welding machine is primarily designed to remove irregular sections of the tail end of the preceding steel strip roll and the leading end of the subsequent steel strip roll. The sheared strip ends are aligned and welded together by using the argon arc welding machine with TIG butt welding technology, enabling continuous feeding to steel strip accumulator. The DJJ series includes three types of products based on shear dynamics: pneumatic, hydraulic, and hybrid (pneumatic clamping with hydraulic shearing). Based on control methods, our products are categorized into two types: button-controlled units and touchscreen-controlled units.The image shows our Model No. DJJ-500B+ hydraulic shear-welding machine. Video is attached.

Our DJJ series shear welder consist of four core components: shearing mechanism, positioning system, clamping mechanism, and welding assembly. The entire welding process is automatically completed under the control of the electrical control cabinet.

The gantry-type (ZDJ series) shearing and welding machine is an efficient automated processing equipment that integrates metal strip shearing and welding functions. It is mainly used in fields such as steel pipe, cold-forming profile, steel structure, automobile manufacturing, shipbuilding engineering, and bridge construction. It addresses the process needs of strip docking, achieving automatic continuity from metal strip shearing to precise welding. The machine adopts a gantry-type frame structure, combines a CNC system with high-precision actuators, and has outstanding features such as high shearing precision, stable welding quality, and high automation degree. It can significantly reduce the intensity of manual operation and improve the automation level of the production line.

The open type (BDJ series) automatic shearing and butt welding machine is our newly developed product according to user requirements, aiming to improve the demand for automated steel strip butt welding. Its basic parameters are as follows: ●  Steel strip width: 80-600mm ●  Steel strip thickness: 0.5-5mm ●  Applicable material: Stainless steel, carbon steel(other materials such as aluminum, titanium, and red copper etc.).

The vertical (DJJ series) shear welding machine is an efficient welding equipment that integrates metal strip shearing and butt welding functions. It is mainly suitable for the continuous production processing of cold-rolled steel sheets, galvanized sheets, and coated steel sheets. The equipment's shearing and welding stations adopt a vertical structure design with an upper-lower layout. The structure is simple, the layout is compact, and it can significantly improve the efficiency of metal strip docking. It has the characteristics of being economical and practical, and widely used in steel pipe welding production lines, cold-forming profile production, stamping processing, and other industries that use metal coils, strips as raw materials.

This automatic column welding machine is an industrial-grade automated welding solution designed for high-volume production. Featuring a heavy-duty gantry frame structure and dual-station welding heads, it enables high-efficiency, automatic welding of various column-type workpieces. Compared to traditional manual welding, it standardizes and automates the welding process while significantly improving weld quality consistency and production efficiency. It serves as a core upgrading solution for industries like steel structure columns and mechanical components.

The machine is used for collecting round, square and rectangular pipes at the end of welded pipe production line. Single round tubes can be stacked into hexagonal bundles, square and rectangular tubes into square bundles, which can be transported to the bundling station. After manual bundling, they can be hoisted and put into storage.

The round pipe packing machine is used to stack round pipes into standard hexagonal bundles, which are then manually or mechanically binded into bundles. Currently, there are two types of pipe arrangement methods for the round pipe packing machine: one is the electromagnetic chuck type, and the other is the mechanical fork type. The advantage of the electromagnetic chuck type is its flexible adjustment for pipe arrangement. The disadvantages are of the complex structure, high cost and steel pipes after being attracted by electromagnetic have residual magnetism. The advantage of the mechanical fork type is its low cost and simple maintenance, but it is troublesome to adjust. Therefore, both pipe arrangement methods have their own advantages and disadvantages.

The square tube (including rectangular tube) packing machine is used to collect the square tubes at the end of the welded pipe production line. It can stack single square tube into square bundles, transport them to the binding position, and then they can be hoisted and stored after manual or mechanical binding. Compared with manual stacking of square bundles, the use of a packing machine can reduce the number of workers, reduce the intensity of manual labor, improve efficiency, and reduce production costs.
