JBH Corrugated Web H-beam Automatic Welding Line

I. Machine introduction

The JBH corrugated web automatic H-beam welding line developed by our company consists of slitting and cut to length machine, web forming machine, flange, web feeding machine, corrugated web H-beam robot automatic welding machine, cross-section cutting, stacking system and so on. The corrugated web H-beam automatic welding machine adopts the welding robot originally from Italy which automatic controls the works such as whole line laser scanning, two positions welding, welding gun changing, cross-section cutting and so on. This machine has high quality, high efficiency, full-automation and so on.

II. Product feature and usage

Corrugated webs H-beam is a new type of construction material, which is widely used in bridge, column, single-span or multi-span frame construction. Its surface is corrugated, it can save steel 20%-60% under the same yield strength compared with flat web H-beam, especially it has high cost performance in large-span, crane beam and so on. (The span of 1.5m corrugated webs H-beam can reach 40m). Corrugated webs H-beam meets the requirement of energy saving, and it shall be the development trend in future.
