In the field of modern pipe processing, the requirements for precision, surface quality, and production efficiency of square welded pipes are becoming increasingly stringent. Traditional argon arc welding or high-frequency welded pipe processes often face pain points such as large heat affected zones, rough welds, and high polishing costs when dealing with high-strength steel, stainless steel, and special alloys. The Fully Automatic Square Tube Laser Welding Roll Forming Machine has emerged, which perfectly combines advanced laser welding technology with high-precision cold bending forming process, bringing revolutionary precision pipe making experience to the industry.

Equipment Introduction

Fully Automatic Square Tube Laser Welding Roll Forming Machine is a continuous fully automatic production line. The equipment starts from feeding the coil material and undergoes continuous cold bending and rolling to gradually transform the steel strip into an open square tube billet. Then, it seamlessly connects with the fiber laser welding unit to achieve high-speed docking and fusion of the pipe seam. Afterwards, the finished square tube is produced through sizing, straightening, and online cutting. This unit is particularly skilled in producing precision square tubes with thin wall thickness, small corner radius, beautiful welds, and high strength.

Application scenarios：

• High end furniture and commercial display
Used for producing irregular bright square tubes such as coffee table legs, office chair racks, and shelf columns. Laser welding seams are smooth and shiny, and can achieve a mirror effect after simple polishing, perfectly replacing traditional frosted pipes and significantly improving product quality.

• Architectural Decoration and Curtain Wall
Suitable for building sunshade louvers, door and window profiles, stair handrails, etc. Compared to high-frequency welded pipes, laser welded pipes have a higher yield rate and no visible welding marks after drawing, making the building appearance more modern and technological.

• Automotive lightweighting and precision machinery
Suitable for car seat frames, luggage racks, exhaust pipe components, as well as fitness equipment, medical equipment carts, etc. This device can ensure excellent torsional strength and fatigue life of square tubes, meeting the dual standards of lightweight and safety.

• New energy and heat exchange equipment
Used for producing photovoltaic bracket square tubes, energy storage battery shell heat dissipation tubes, etc. For thin-walled stainless steel square tubes, laser welding can effectively avoid burn through and oxidation, ensuring the corrosion resistance of the equipment in harsh environments.

Core Features

1.Precision molding with strict dimensional tolerances
Adopting a modular roller pressing mold design, each set of rollers undergoes CNC precision machining to ensure that the side length, diagonal, and flatness errors of the square tube are controlled within a very small range. Whether it is producing pipes for construction or automotive structural components, it can ensure extremely high dimensional consistency.

2.Laser welding, the weld seam is almost perfect
Integrated high-performance fiber laser with high energy density and concentrated heat input. After welding, the depth to width ratio of the weld seam is large, the grain size is small, and the heat affected zone is extremely narrow. The welding speed has significantly improved compared to traditional processes, and the surface of the weld seam is flat and smooth, almost without the need for subsequent polishing treatment, directly meeting the high standard requirements for appearance of high-end home furnishings, fitness equipment, and other products.

3.Strong adaptability, considering multiple materials
It can stably process various metal materials such as stainless steel, carbon steel, galvanized sheet, high-strength steel, etc. Whether it is producing mirror stainless steel square tubes for decoration or thick walled square tubes for load-bearing structures, simply replace the corresponding molding mold and fine tune the laser parameters to quickly switch production tasks.

4.Intelligent control, highly automated operation
Equipped with PLC fully automatic control system and HMI human-machine interface. From uncoiling, shear welding, storage sleeve, forming welding, to flying saw tracking cutting, the entire line achieves closed-loop control. Equipped with real-time welding seam tracking function, ensuring that the laser spot always accurately locks the center of the weld seam, effectively avoiding missed welding and welding deviation.

5.Energy saving and environmental protection, reducing overall costs
Laser welding does not require consumables such as welding rods or fluxes, and there is no splashing pollution. Compared to traditional pipe manufacturing processes, it has lower power consumption and significantly saves labor and sand belt consumables costs by eliminating the subsequent weld polishing process. The workshop environment is also cleaner.
