Quick Detail:

Box column slag welder is a special equipment for box column baffle welding

Description:

Box column slag welder is a special equipment for box column baffle welding, which adopts baffle , surround steel plate welding hard in vertical slag welding way. According to customer's different requirement, these are two ways of box column slag welding: fuse and fuse tip. Welding speed of fuse slag welding is faster and lower welding cost, but higher equipment cost, more complicate control system ;fuse tip slag welding is lower equipment cost and simple operation, but the welding effenciency is lower than fuse slag welding. Fuse slag welding is suitable for big quantity box column prodction, while tip slag welding id suitable for small quantity.

Specifications:

a. Structure principle

Cantilever electro-slag welding machine is the main device in Box-beam welding production line. It is a special machine for welding the seams between baffle plate and bottom plate. There are two kinds of welding types for Box-beam baffle plate electro-slag welding: nozzle melt and wire melt.

Nozzle melt is a kind of electro-slag welding that melts the contact tube (nozzle) and welding wire together. The contact tube will stay while welding wire is fed when welding. Actually, contact tube comes to be a part of welding wire. Features for nozzle melt electro-slag welding:

Electro-slag welding part has a simple structure. Its welding power often comes from our country, so the cost will be low.

There’s welding flux covering the contact tube. It will join the process of melting the metal, and improve the organizational structure of metal in welding seam.

The contact tube will be melt with wire, so it is expendable, the cost will be high, and different sizes of Box-beam needs different contact tubes.

Using φ2.4mm welding wire, welding speed is slower than wire melt type.

Wire melt electro-slag welding adopts special contact tube. When welding wire is fed the contact tube will be lifted. Features for wire melt electro-slag welding:

Because the contact tube will be lifted when welding, electro-slag welding part’s structure will be complex, so as the contact tube. Its welding power often uses American Lincoln welding machine, so this cost is higher than nozzle melt type.

The contact tube won’t melt when welding, it can be recycled, so the cost will reduce.

Using φ1.6mm thin welding wire, current density is larger, and wire melting speed is faster, so the welding efficiency will be improved.
