For welding vertical up, use a push or forehand technique and tilt the top of the electrode 0 to 15 degrees away from the direction of travel. This is the relationship between the torch and line of travel. A travel angle of 0° to 10° (i.e., the electrode perpendicular or mostly perpendicular to the plate) will result in more weld penetration. The following chart shows how some CLAMS variables impact a weld bead: In the last two examples, "WFS" stands for wirefeed speed, which is how MIG and flux cored welding machines regulate current. Some welds are covered by specific codes that prohibit peening so you should check the weld specification before peening. Ideally, you'll hold your torch perpendicular, or 90 degrees, to the joint. For most wire welding applications, this angle is 15 to 30 degrees. What is the work angle and travel angle for Lap Joints in the Flat Position when welding a multi-pass? Work angle is especially important in multiple-pass fillet welding. In most conditions, this will be between 5 and 15 degrees. And while low-carbon steel is much easier to work with than other metals, you should still adopt the habit of cleaning or grinding the areas you plan to weld. Quenching plates after welding (to cool them down) is a practice that's generally frowned upon after the first semester of welding school. Technically it is the angle your electrode takes (or the centerline of your torch/gun) in reference to the line which is at a right angle to the welds axis and the weld axis plane. Producing a weld bead that's the right size, shape and depth involves many variables. When you are push welding you are forehand welding. When you push, the tilt is away from the puddle, which limits penetration and heat going into the base metal. Traveling angle denotes to the perpendicular position of the gun whilst working angle is more important as it denotes to the position of the gun in relation to the welding joint angle. The normal travel angle for all sorts of conditions and positions are from 5 to 15 degrees. Strike the tip of the new electrode at the forward (cold) end of the crater and establish an arc. The major cause of undercuts in welding is when the operator (welder) uses a high welding current or welds with fast travel speed. The pool of molten slag is wide, tall and bubbly, and shouldn't be mistaken for the weld pool! In a wirefeed operation (i.e. When learning any new process you'll likely start off doing things wrong. The most commonly used method to break the arc is to hold the electrode stationary until the crater is filled and then slowly withdraw the electrode. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -. Speed: Watch the welding puddles and ridge (where the molten metal solidifies). The second angle used in welding is the travel angle. Travel speed is the rate at which the electrode travels along a weld seam. This angle can also be used to partially define the position of guns, torches, rods, and beams. As the angle between the electrode and the plate determines the point of impingement and direction of the arc force, it has a critical effect on the weld bead profile and depth of penetration. (In MIG welding, steeper angles are possible than in stick welding.) When you are welding a joint that has the same thickness then your work angle will take place in the center of the joint. Similar to MAG welding torch position and angles can be applied (however rutile flux cored will require different techniques). The angle of the tip and the travel speed while welding can alter the weld depth. For wire welding, Hoes and Liesner recommend holding the gun at a 10 to 15-degree angle. /* 120x600, created 3/17/09 */ For stick welding, you have to drag the weld. Arc welding faults. The flame is pointed in the direction of welding and directed between the rod and the molten puddle. Travel Speed In most cases, weld penetration into a base material is increased when the travel speed of a weld is increased, and vice versa. Normally it should be around 5 to 15 degrees. This setting allows you to increase the current above the set output amperage if your arc starts to fizzle out. 2F is a fillet weld position, in which the welding is done on the upper side of the surfaces that is approximately horizontal that lies against a surface that is approximately vertical. google_ad_client = "pub-0048113051831248"; Hold the electrode perpendicular to the joint, and then tilt the top in the direction of travel approximately 5 to 15 degrees. Some stick machines also have a setting known as Dig. When you drag your torch or electrode, the tilt is directed towards the puddle, which helps with penetration and achieving a thick bead. What is the travel angle? TheFabricator.com, , Welder Qualification Test Via Advice section, Open root v groove butt joint 3G vertical up. Direct current reverse polarity c. Direct current straight polarity d. Direct current electrode negative Two inert gases used in GMAW are . Beginner welders tend to move the rod too quickly, especially those who are transitioning to arc welding from another welding process. What polarity does GMAW-P require? This position permits uniform preheating of the plate edges immediately ahead of the molten puddle. The angle relative to the gun if it were held in a perpendicular position to the surface of the weld. So voltage determines the overall profile, or geometry, of the weld. The electrode angle consists of two positions: work angle and travel angle. The angle at which you hold the electrode greatly affects the shape of the weld bead which is very important in fillet and deep groove welding.
