H-Beam Welding Machine

1. Brief introduction

BMHW-1500 welding line for H-profile steel is a wonderful technical product

that integrates mechanical, electric, and pneumatic technologies. The machine, using advanced technology ofsingle-arc double-wire welding, greatly increases the production efficiency.

It consists of welding machines, assembling machine and conveyor.

After fixing the position for the web and two flanges of H-profile steel,

the welding machine can automatically localize, clamp, adjust, weld, transport until finishing all the work.

The automatic mode of this line greatly lowers the cost of manufacture. BMHW-1500 welding line for H-profile steel consists of assembling machine(1set), welding machine (2sets), turn over device(1 set), 75m conveyer. It is applicable in mass production of H-profile steels.

2. Characteristic of the line

A. Advanced welding line

BMHW-1500welding line is used to produce H-profile product specially.

This line is applied single-arc double-wire welding technology. The welding machine is DC-1000 Lincoln welding machine which is an international famous brand,

and the control system for feeding welding wire is NA-5 style Lincoln.

All the system is operated by hydraulic oil. The control system is Mitsubishi PLC,

which makes the line work automatically. The length of H-profile product made by this line is 2-15 meters.

B. Ascendant performance

BMHW-1500 profile welding line is not only easy to operate, but also has high automatic

and low distortion performance.

At the same time, it has reasonable structure, so there is no adjusting trouble when doing different size H-beam product. There is little heat radiation because of using immersed arc welding,

so there is almost no negative effect to the operator.

It has long life and high stability performance, and easy to be maintained and be managed.

C. Special welding agent and welding wire store system

You can use the recycle pipe to absorb the welding agent into the store tank if want to add welding agent,

or put the welding agent into the store tank directly after opening the cover of the tank.

When in busy working condition, use the recycle pipe to absorb the welding agent into the store tank directly, which saves working time, lightens the working intensity, improve working efficiency.

The store tank for welding agent is big enough to be used several days when you make it full, so there is no trouble of adding welding agent.

3. Assembling machine

A. Brief introduction

The assembling machine is used to transport the steel plate according to requirement and position fixed them to be H profile.

and it can adjust the position of web and flanges slightly keeping the H-profile unchanged in order to spot weld.

All the operation actions are finished through hydraulic system by press buttons on control panel.
