SAW Welding Machine

Submerged Arc Welding is a procedure of joining that includes forming an electric arc between the workpiece that is to be welded and a continuously fed electrode. A powdered flux blanket covers and surrounds the arc and offers electrical conduction between the electrode and the metal that is to be joined. This process even creates a protective gas shield to protect the weld zone. This entire process is performed using a SAW welding machine.

Description Of SAW Welding Machine

A submerged arc welding machine creates a strong weld using the granulated flux blanket. Due to this, the process is performed only on surfaces that are horizontal and flat. The SAW welding machine feeds flux into the joint manually or using a flux hopper. A multiple-wire electrode system or a single-electrode system is located in the working area, which is covered by the flux blanket.

Parameters, including voltage, welding current, and wire feed speed, are fixed on the basis of the metal type, desired mechanical properties, and thickness. Hence, electric current is flowed to the electrodes to produce intense heat, melting and fusing the base material and the filler wire. Therefore, the molten metal further cools down to create strong, uniform welds.

Features of SAW Welding Machine

A SAW welding machine creates high-quality welds with fewer defects than other processes. Some major features of a SAW welding machine include the following:

• Better reliability with SMD technology
• Energy-efficient machines manufactured with high power factor and high efficiency to reduce energy bills and save electricity consumption.
• Several models of SAW welding machines come with multiple built-in technologies, including digital inverters, IGBT inverters, inverter-based functionality, ultrasonic transformers, digital MCU technology, and many more.
• Most SAW welding machines are manual, automatic, semi-automatic and electric.
