Name: Corrugated Web H-beam Welding Line
Brand: ZHEJIANG JINGGONG INTELLIGENT BUILDING MATERIAL EQUIPMENT CO., LTD.

The corrugated web H-beam automatic welding machine adopts the welding robot originally from Italy which automatically controls the works such as the whole Line laser scanning, two positions welding, welding gun changing, crosssection cutting and so on. This machine has the features of high quality, high efficiency, full-automation and so on.

It can cut, assemble and weld the tapered beam. The welding speed of this production line is about 700 mm/min (max. projected linear average speed). For the raw materials to feed into the machine, load the suitable coil onto the decoiler or simply feed the flat plate are both OK.

The length, height and thickness the machine can produce:

H-beam length: 4-16 m

H-beam height: 300-1500 mm

Corrugated web thickness: 2-6 mm(≤235 MPa), 2-4 mm(≤345MPa)

H-beam flat web thickness: 4-8 mm

Video of Corrugated Web H-beam Welding Line

Corrugated web H-beam is a new construction materials. It is widely used in bridge, column, single and multiple bay frame construction. The surface is corrugated, and it can save steel 20%~60% under the same yield strength with each beam with flat webs, especially it has high cost performance in large span, crane beam, and so on. The span of 1.5 meters H-beam with corrugated webs can reach 40 meters. The JBH automatic corrugated web H-beam welding line is developed by Zhejiang Jinggong Science and Technology Co., Ltd. The H-beam with corrugated webs use the original binding welding robot from Italy with automatic control to finish the work such as whole line laser scan, two positions welding, changing welding gun, cross-section cutting, and so on.

The machine has high quality, high efficiency, full automation, and so on. It consists of slitting and cutting length devices, web panel forming machine, flange web feeding machine, h-beam with corrugated webs robot automatic welding machine, variable cross-section cutting, stacking system, and so on.

In order to promote the use of H-beam with corrugated webs. Zhejiang Jinggong Science & Technology Co., Ltd., Tongji University in Shanghai, Open Steel Structure, and other companies made the product standard for the industry. And in september 2010, it passed the review.

Special features about Corrugated Web H-beam Welding Line

1. The maximum load-bearing design with the optimized self-weight can save 20%-60% of steel under the same strength of H beam.

2. Beautiful appearance. The corrugated appearance of the web is unmatched by the original flat web.

3. Large-span application has high-cost performance and the maximum 1.5 m web beam spans over 40 meters.

4. Multi-purpose, corrugated web structure has been widely used in bridges, columns, single-span, multi-span frame structure.

5. It is the future trend to meet the requirements of energy-saving and consumption reduction.
