ZELDA SUBMERGE ARC Welding Machine

Submerged arc and automatic equipment includes welders and wire feeders for heavy fabrication environments.

Submerged arc welders from Zelda provide maximum control over deposition and penetration in single or multi-arc environments. Beam-mounted, portable tractor or semi-automatic systems available for heavy fabrication environments. Input current requirements are reduced with our inverter-based system, resulting in significant energy savings.

ZELDA SAW Welder

The power sources have the capacity to handle Submerged Arc (SAW) and Electro slag (ESW) welding applications, from traditional DC single-arc to multi-wire tandem welding. In the case of ESW welding or other high-current demand, two or more power sources can easily be paralleled.

In addition to these power source options, the machines offers two interface controls — analog and digital — and a range of wire drive motors and accessories, including single- and twin-wire torches, and external cladding heads. The accessories are powered with a safe, low control- voltage (24 VAC) from the power source.

What Is Submerged Arc Welding?

Submerged arc welding or SAW is a form of welding that takes place underneath a layer of flux material. This material could be any of a variety of different compounds. The flux material acts as a guard against contamination in the weld, also creates sparks to shield the arc.

Submerged arc welding is commonly used in industries where thick steel sheets are involved or where long welds are required. The process consists in creating a welded joint between steel components using an electric arc submerged beneath a layer of powdered flux.

Why do we need SAW Welder?

Today, many factories have high demand for products that require welding. Submerged arc welding allows for those to be carried out quickly and consistently. Submerged arc welding is also a much safer way of performing welds using arc welding.

There is a variety of saw equipment available, including welding tractors that are used to automatically weld a seam, and flux recovery units, that use a vacuum to “hoover “up excess flux from the weld.

Often used alongside positioning equipment, like column and booms and pipe rotators, sub arc equipment is used in pipe and vessel fabrication within a variety of fabrication industries.

Submerged Principle of the process

Submerged-arc welding (SAW) involves the formation of an arc between a continuously fed wire and the workpiece. A blanket of powdered flux creates a protective gas shield and a slag for the weld zone. A shielding gas is not required. The arc is submerged beneath the flux blanket and is not normally visible during welding.

SAW is normally operated in the automatic or semi-automatic mode. The process is normally limited to the flat or horizontal-fillet welding positions.
