The plasma nozzle has a unique design feature, where the electrode is located within the body of the torch. <strong>This allows the arc plasma to exit the torch separated from the shielding gas envelope.<\/strong><\/p>\n<p>Additionally, the narrow opening of the nozzle increases the plasma gas flow rate, allowing for deeper penetration. While filler metal is typically supplied at the weld pool&#8217;s leading edge, it is not the case when creating root pass welds.<\/p>\n<p>The complexity of the plasma welding torch sets it apart from gas tungsten arc welding. <strong>Plasma welding torches operate at very high temperatures<\/strong>, which can melt away their nozzle, making it a requirement to always be water-cooled. While these torches can be manually operated, nowadays, <strong>most modern plasma welding guns are designed for automatic welding<\/strong>.<\/p>\n<p>The most <a href=\"https:\/\/fractory.com\/welding-defects-types-causes-prevention\/\">common defects<\/a> associated with plasma welding are tungsten inclusions and undercutting. Tungsten inclusions occur when the welding current exceeds the capabilities of the tungsten electrode and small droplets of tungsten get entrapped in the weld metal. Undercuts are generally associated with keyhole mode PAW welding and can be avoided by using <a href=\"https:\/\/weldknowledge.com\/2015\/10\/03\/plasma-arc-welding-paw-with-activated-flux\/\" target=\"_blank\" rel=\"noopener\">activated fluxes<\/a>.<\/p>\n<h3>Plasma Arc Welding Operating Modes<\/h3>\n<p>Three operating modes are used in plasma welding, wherein it can be operated at varying currents:<\/p>\n<h4>Microplasma (0.1 &#8211; 15A)<\/h4>\n<p>This operating mode can run arcs at low currents and remain stable up to 20mm arc length.<\/p>\n<p>Microplasma welding is used to join thin sheets up to 0.1 mm in thickness, which is optimal for creating wire meshes with minimal distortion.<\/p>\n<h4>Medium current (15 &#8211; 200A)<\/h4>\n<p>The characteristics of the plasma arc are quite similar to TIG welding, but the arc is stiffer since the narrow opening of the torch restricts the plasma. We can increase weld pool penetration by speeding up the plasma flow rate, but this increases the risk of shielding gas contamination.<\/p>\n<p>Medium current or melt-in mode offers better penetration than TIG and improved protection. The only drawback is that the torch requires maintenance and is bulkier compared to a TIG torch.<\/p>\n<h4>Keyhole mode (over 100A)<\/h4>\n<p>A powerful plasma beam is used to engage in high-current aka keyhole mode by increasing the gas flow and welding current. This mode allows deep penetration, using a single pass (up to 10mm thick for some materials) to create a consistent weld pool from molten metal.<\/p>\n<p>Similarly to <a href=\"https:\/\/fractory.com\/electron-beam-welding-ebw-explained\/\">electron beam welding<\/a>, the keyhole mode is great for welding thicker materials at high welding speeds. To guarantee satisfactory welds, filler material is generally added. Its welding applications include mechanised welding, positional welding, and pipe welding.<\/p>\n<h3>Comparison of Plasma and TIG Welding<\/h3>\n<p>Normally, a tungsten electrode is used in TIG welding to strike an arc between the torch and the workpiece. The plasma process works similarly but uses a different setup in its welding torch. The constricted nozzle design allows electrons to move at high velocities. This ionises the gas, creating a plasma jet with a high heat concentration, offering deeper penetration.<\/p>\n<p>As plasma welding offers greater precision than TIG welding, it has a smaller <a href=\"https:\/\/fractory.com\/heat-affected-zone-causes-effects-reduction\/\">heat-affected zone<\/a> which is perfect for creating narrower welds. Ideally, plasma welding is a better choice than TIG welding, as it is an evolution of the latter. The technology behind its equipment allows it to run with lower current demand, and better arc stability which leads to better stand-off distance, and better <a href=\"https:\/\/fractory.com\/engineering-tolerances\/\">tolerances<\/a> if the arc length is changed.<\/p>\n<p>TIG welding however is a simpler method due to the complex parameters available for plasma gas welding. An operator would need extra training in order to transition from the already advanced TIG welding to PAW. And last, TIG welding equipment is cheaper and requires less maintenance than plasma arc welding&#8217;s sensitive and complex torch.<\/p>\n    <div class=\"shortcode-enhanced-cta\">\n        <div

class=\"wp-caption-text\">Plasma torch &#8211; plasma gas is separated from the shielding gas envelope.<\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<p>The unique design of the water-cooled plasma torch is the main distinguishing factor from other welding processes. Its operating principles have already been explained in previous sections.<\/p>\n<p>Depending on the weld material and desired weld characteristics, different types of nozzle tips can be selected.<\/p>\n<h4>Control console<\/h4>\n<p>While conventional welding techniques directly connect a torch to a power source, plasma arc welding uses a control console between the two.<\/p>\n<p>Some of the console features are the torch protection circuit, high-frequency arc starting unit, power supply for the pilot arc, water, and gas valves, individual meters for plasma, and shielding gas flows.<\/p>\n<h4>Power supply<\/h4>\n<p>Plasma arc welding uses DC power (rectifiers or generators) of at least 70 volts for open circuit voltage with drooping characteristics to have greater control in generating weld beads.<\/p>\n<h4>Gases used<\/h4>\n<ul>\n<li>\n<p>Plasma gas &#8211; exits the constricting nozzle separately from the shielding gas envelope and becomes ionised<\/p>\n<\/li>\n<li>\n<p>Shielding gases (argon, helium, hydrogen) &#8211; inert gas protects the weld from the atmosphere<\/p>\n<\/li>\n<li>\n<p>Back-purge and trailing gas &#8211; certain materials require special conditions<\/p>\n<\/li>\n<\/ul>\n<h4>Wire feeder<\/h4>\n<p>Plasma welding may use wire feeders with a constant velocity that can be modified to run from 254 mm per minute to 3180 mm per minute.<\/p>\n<h3>Applications<\/h3>\n<h4>Steel tubes<\/h4>\n<p>PAW is a great welding method in manufacturing steel tubes as it can be performed at high-speed welding with great metal penetration. Some industries prefer the plasma welding process to conventional TIG since its system is faster and uses less filler material.<\/p>\n<h4>Electronics<\/h4>\n<p>One of the welding parameters of the plasma welding process is it can run at low current modes. This mode allows small metal component welding, which deals with delicate materials sensitive to environmental factors.<\/p>\n<h4>Medical industry<\/h4>\n<p>Medical devices require precise components in order to run effectively. PAW is perfect for welding these components as it can reliably create a consistent weld bead.<\/p>\n<h2>Advantages of Plasma Welding<\/h2>\n<ol>\n<li>\n<p>Can be operated in every welding position.<\/p>\n<\/li>\n<li>\n<p>Fast travel speeds from concentrated heat input.<\/p>\n<\/li>\n<li>\n<p>Keyhole welding allows for complete penetration.<\/p>\n<\/li>\n<li>\n<p>Low current mode is suitable for thin and sensitive components.<\/p>\n<\/li>\n<\/ol>\n<h2>Disadvantages of Plasma Welding<\/h2>\n<ol>\n<li>\n<p>Expensive equipment and components.<\/p>\n<\/li>\n<li>\n<p>Requires training and skill to create good welds.<\/p>\n<\/li>\n<li>\n<p>Produces 100dB noise.<\/p>\n<\/li>\n<li>\n<p>Creates ultraviolet and infrared radiation.<\/p>\n<\/li>\n<li>\n<p>Water cooling is necessary because of high working temperatures.<\/p>\n<\/li>\n<li>\n<p>Delicate equipment needs a higher amount of maintenance.<\/p>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>Plasma welding is an arc welding process that uses a plasma torch to join metals.
