Due to the thickness of steel plates generally required to build ships of any size and type, it is essential that you have high-current, high-efficiency welding solutions available to you during the ship building process. Out of all the types of welding machines which are on the market today, one machine in particular which stands out as being very well suited for heavy-duty applications is the ZDE7-1200HD Inverter AC/DC Arc Welding Machine. This article will discuss the various features and benefits of this machine, how it can be used within the shipbuilding industry, as well as the answers to many commonly asked questions regarding this process.
Versatile AC/DC Modes with One-Key Switching
With its easy-to-use interface, the ZDE7-1200HD makes it simple for welders to select between AC Welding, DC Straight Polarity and DC Reverse Polarity with the touch of a button (one click operation). Because of this flexibility and ease of use, the ZDE7-1200HD saves valuable time during adjustment to different types of base materials and joint configurations when working on shipbuilding projects where making every second count is vital.
Superior Arc Stability & Start Success
The ZDE7-1200HD offers a high degree of reliability when it comes to arc ignition and providing a constant arc. This technology is critical to the success of long seams and complex automated submerged arc welding (SAW) on shipyards’ production lines. By incorporating this technology, users can expect to have increased uptime for longer periods of time while improving output quality.
Precise Bead Control for Optimal Welding
The ability to fine-tune three independent AC output parameters (frequency, waveform, and DC bias) is another great aspect of this machine. These settings allow welders to modify the bead shape, penetration, and efficiency of deposit. By adjusting these settings, a welder can control heat input and reduce distortion on large ship panels, thus producing high-quality work for heavy plate welding jobs.
Scalable Output via Parallel Control
You can connect the ZDE7-1200HD in parallel to allow for higher power outputs that can accommodate any welding process you may need—single- or double-wire single-pass; or triple wire and four alpine for example. With the changing demands placed on ships by busy shipyards, this flexibility becomes vital.
Reduced Arc Interference Technology
Through cross-phase control technology; it is possible to produce consistent weld quality from a variety of workstations, because the design of this feature greatly reduces the possibility for arcs to interfere with one another and is therefore appropriate for multi-station and multi-wire submerged arc welding, especially important when welding the large structures that are often found in shipbuilding.
100% Duty Cycle at 40°C
When operating at high levels of activity, the ZDE7-1200HD has a 100% duty cycle at 40°C; therefore it is capable of operating under very demanding operations and/or high ambient airflow and temperatures typically found in shipyards. The durability of the product assures reliable operation and reduces the amount of time the machine is not being utilized. This enhances the productivity capabilities of that piece of equipment.
Robust Protection & Reliability
Not only is it a very powerful Electrical Multi-Process Machine but also comes equipped with over temperature, under voltage, and phase failure protections. This Equipment is within an IP21S Enclosure and Class F rated Insulation for Welders to rely on for use in the tough conditions common in Shipbuilding.
Compact & Portable Design
The ZDE7-1200HD is designed for job sites with a light weight of just 210 kg and overall dimensions that measure only 940 mm (W) x 475 mm (D) x 1245 mm (H). Its combination of size and weight makes it ideal for transporting to work locations as well as allowing welders to efficiently complete their tasks at shipbuilding facilities and anywhere else.
Ideal Shipyard Applications
The applications for the ZDE7-1200HD are extensive, including:
