vertical electrogas welder

CLH-II vertical Electrogas welder is used for auto welding vertical seam for large storage tank in normal construction.the equipment ride on the edge of wall of tank and run along the shell to each of verticlal seam , It adopts special-purpose flux-cored wire protected by CO2. It also adopts the enclosed welding technique by cycling cooling water.

The face of weld is directly in the way of the water-cooling slip shoe, while the back of weld uses the water-cooling copper shelter line or ceramic backing. The welding tractor runs along the stiff track with the welding gun and slip shoe, rising with the weld molten pool synchronically.

These actions force the weld to shape in only one time by cooling water, which can obtain pretty appearance of weld and products with high quality.

The electrogas welding automatic operation machine is mainly used in automatic welding worksite for large steel structure such as oil tank, blast furnace, hot-blast stove, tube-shaped object, hull, pipeline and so on. The operation is simple and convenient with high quality and high efficiency.

The main characteristics of electrogas welding automatic machine include:

1, High welding quality

The electrogas welding operation machine is compactly organized. The welding tractor runs smoothly and steadily. The welding process is conformed to the standard, and has excellent regulating performance, which can obtain pretty appearance of weld and products with high quality.

2, Entire automation

The electrogas welding operation machine has very simple parameter regulating so it can be easily controlled. The operation machine is fitted with control box, on which all the welding control works are completes. Welding speed can fit the rising speed of the weld molten pool automatically. It is an entire automatic welding process.

3, High efficiency

The electrogas welding is the highest produce efficiency method in all the arc welding methods, which is 30 times of that completed by shielded metal arc welding. It only cost 20 minutes to weld a 2400mm vertical weld on a 20mm-thick plate by electrogas welding, which costs more than 10 hours by shielded metal arc welding.

4, Imporved working condition

The electrogas welding operation machine can greatly reduce the intensity of labor, improve the working condition. It doesn’t require very high welding skill of the operators. The operators can skillfully operate the machine after simple training.
