SAW Welding Equipments / Systems / Machines

Here's a breakdown of the typical equipment used in submerged arc welding:

• Power Source: SAW typically utilizes a constant current (CC) welding power source. These power sources provide the necessary electrical energy to sustain the welding arc. They are designed to deliver a stable arc and are often equipped with features for voltage and current control.
• Welding Head: The welding head holds the welding torch and guides the electrode along the joint being welded. It may be manually operated or mounted on a mechanized or automated system for consistent and precise welding.
• Electrode: In submerged arc welding, a consumable electrode is used. This electrode is typically a coil of wire that is continuously fed into the welding arc. As the wire melts, it forms the weld bead. The composition and diameter of the electrode wire depend on the material being welded and the specific welding application.
• Flux Handling System: SAW uses a granular flux to shield the welding arc and protect the molten weld pool from atmospheric contamination. The flux is fed from a hopper through a flux delivery system to surround the welding arc. Some systems may include flux recovery units to recycle and reuse the flux.
• Wire Feeder: A wire feeder mechanism delivers the electrode wire from a spool to the welding torch at a controlled and consistent rate. This ensures a steady supply of filler metal to the weld pool.
• Welding Positioning Equipment: Depending on the application, SAW may be performed in various positions, including flat, horizontal, vertical, and overhead. Welding positioning equipment such as turntables, manipulators, or positioners may be used to orient the workpiece for optimal welding.
• Control System: Many submerged arc welding systems incorporate control systems that allow operators to set and adjust welding parameters such as wire feed speed, arc voltage, and travel speed. Advanced systems may feature digital interfaces and programmable settings for precise control and automation.
• Safety Equipment: As with any welding process, safety equipment such as welding helmets, gloves, protective clothing, and ventilation systems are essential to protect welders from hazards such as arc radiation, fumes, and sparks.

These components work together to create a controlled environment for submerged arc welding, resulting in high-quality welds with excellent mechanical properties and minimal distortion.
