Pulse Welder: A New Technology for High-Quality Welding

Welding is a process of joining two or more metal pieces together by applying heat and pressure. There are different types of welding methods, such as arc welding, gas welding, resistance welding, and solid-state welding. Each method has its own advantages and disadvantages, depending on the application and the materials involved.

One of the most common and versatile welding methods is arc welding, which uses an electric arc to create a pool of molten metal between the workpieces. Arc welding can be further divided into different modes of metal transfer, such as short circuit, globular, spray, and pulse.

In this article, we will focus on pulse welding, a new technology that offers high-quality welding results with less heat input, less spatter, and less distortion. We will also introduce Megmeet's quick pulse welding technology and its pulse welding solutions.

I. What is Pulse Welding?

Pulse welding is a variation of arc welding that alternates between a high current (peak) and a low current (background). The high current produces a droplet of molten metal at the tip of the electrode, which is then transferred to the weld pool during the low current. This way, one droplet is delivered per pulse, resulting in a controlled and stable metal transfer.

Pulse welding can be used with both gas metal arc welding (MIG) and gas tungsten arc welding (TIG) processes. With MIG, the electrode is a consumable wire that is fed continuously through the torch. With TIG, the electrode is a non-consumable tungsten rod that creates an arc with the workpiece. In both cases, an inert or semi-inert gas is used to shield the arc and the weld pool from atmospheric contamination.

II. What are the Advantages of Pulse Welding?

Pulse welding has several advantages over conventional arc welding methods, such as:

  1. Reduced heat input: Since the current is pulsed, the overall heat input to the workpiece is lower than in continuous arc welding. This reduces the risk of burning through thin materials, warping or cracking thick materials, and affecting the mechanical properties of heat-sensitive materials.

  2. Reduced spatter: Spatter is the unwanted splashing of molten metal outside the weld pool. Spatter can cause defects in the weld appearance, and waste material, and require additional cleaning or grinding. Pulse welding reduces spatter by controlling the metal transfer and minimizing short circuits between the electrode and the workpiece.

  3. Improved out-of-position welding: Out-of-position welding refers to welding in any position other than flat or horizontal. In these positions, gravity can affect the shape and stability of the weld pool, making it difficult to achieve a uniform and smooth weld bead. Pulse welding improves out-of-position welding by allowing higher deposition rates with less sagging or undercutting of the weld pool.

  4. Enhanced dissimilar metal welding: Dissimilar metal welding refers to welding two or more metals with different physical and chemical properties. This can be challenging because of the differences in melting points, thermal expansion, electrical conductivity, and metallurgical compatibility. Pulse welding enhances dissimilar metal welding by avoiding intermetallic phases that can weaken the weld joint.
