THE SUBMERGED ARC WELDING PROCESS

The arc being shielded and hidden under the flux, high current density can be considered with the following benefit:

Operator protection from arc ray and heat radiation

High deposition rate and high quality welds

Versatile welding process with combination of wire diameter, flux type, single or multiple electrodes, welding current wave shape and welding mode

The submerged arc wire standard portfolio includes different wire sizes, mainly between 2.0 and 4.0 mm wire diameter. The choice of wire size is made in accordance with the welding procedure parameters in order to maximize the current density and increase the melt off rate, without exceeding the wire current carrying capacity.

LONG STICK OUT PROCESS

The combination of the Power Wave® AC/DC 1000® SD Inverter technology with the addition of an extension to the welding torch enables the long stick out process (LSO). The LSO relates to a physical principle which, by pre-heating the wire, improves the fusion of the filler metal and increases the deposit rate without changing the welding current or the travel speed.

Long stick out process can also be used with multiple arc procedure in order to get the optimum output from your Power Wave® AC/DC 1000® SD investment.

SUBMERGED ARC EQUIPMENT

Although the long stick out process may not be new, its effects were limited by the welding generator technology. The Power Wave® AC/DC 1000® SD Inverter and its Waveform Control Technology™ wave-shape control eliminate the arc ignition uncertainties thanks to its special management of the welding current, thus making it possible to make the most of this process’s unprecedented effectiveness.

Power Wave® AC/DC 1000® SD Inverter is the first power source equipped with wave-shape control technology. By working with an alternating polarity, the current’s wave shape can be changed.

By modifying the balance, the Offset and the frequency, it is now possible to increase the deposit rate and deepen the penetration using the same amount of welding energy, easily adjust the shape of the seam and reduce the interactions between the arcs.
Combining AC current and LSO will improve the deposition rates, shorten the welding time, and lead to decreasing the cost of each weld.

LARGE-CAPACITY PACKAGING

Spool changes lead to a lot of idle time and each operation involves a risk for safety. By moving on to large-capacity packaging, you can eliminate these factors… and cut your costs. The calculation is simple: one 350kg drum of wire eliminates 14 changing operations with wire spools weighing 25kg. The Lincoln Electric wire feeding assistance equipment makes it possible to think out the installation in its entirety. Whatever the length of the liners or the size of the wire and packaging, we provide the best solution for turntable, pneumatic wire feeding assistance, wire straightener, connection guide or lifting attachment.

HAVE CONTROL. ANYTIME, ANYWHERE.

With the Power Wave® Software resource center, the user accesses the industry’s best welding solutions: the Power Wave® Manager, CheckPoint™ and WeldScore® software make it possible to analyze and manage its welding data, store and access them on its server and reinforce the quality and production follow-up. All this with regular free updates.
