Note that on material 1/4 inch and thinner, weaving the electrode is typically not needed because the bead will be wider than necessary. Stick Welding - How To Create High Quality Welds 1. "Stick Welding TechniquesBefore welding make a final check and remove consumable material. Horizontal and flat welding positions are the most popular and easiest welding techniques to be done. Choose the Right Electrode SizeLarge electrodes weld at high currents for high deposit rates. Another term for this same welding method is Shielded Metal Arc Welding (SMAW), or Arc Welding for short. Unclean conditions can lead to cracking, porosity, lack of fusion or inclusions. If you have trouble seeing, move your head, rather than lengthening the arc. Easier to use products through auto-settings and better visibility. The type of electrode and the size used for stick welding determine the arc voltage (which ranges between 16 and 40 volts) as well as the amperage (which ranges between 20 and 550 amperes) requirements. Clamp the rod in the stinger at a 45 to 90 degree angle. Start by finding a good body position that gives you an adequate view of the puddle, while also allowing you to stabilize and manipulate the electrode. For example, an 1/8-inch 6010 electrode is held about 1/8 inch off the base material. Choose a Joint Position and Electrode that is Conducive to the MetalJoint position can have a great affect on finished weld quality. If your amperage is too low, your electrode will be especially sticky when striking an arc, your arc will keep going out while maintaining the correct arc length or the arc will stutter. Note toward the end of the bead in the image below how the bead appears inconsistent as if the puddle were trying to keep up. For lap joints, on the other hand, you should keep the degree much tighter, moving the electrode in a circular motion to enhance its strength. multipass stick welding techniques 7018 I am working to bring you more arc/stick welding videos. If there is too much heat input you get burn through. For surface holes, use the same solutions that are used for porosity. For many people, especially those who are new to it or perhaps don’t weld every day, stick welding, otherwise known as shielded metal arc welding (SMAW), is one of the more difficult processes to learn. For those of us that are experienced welders a 3F or 3G vertical up with SMAW can still […] Make sure you have it set correctly for your application. Here the welder uses a semi-circular motion to create a wider bead with a stacked dimes appearance. Or if you don't have a Miller account, create one today. Remove the cigarette lighter from you pocket. The above instruction and technique will help both expert and beginner for welding Al with a stick welder. If you are using AWS E6010 or 11 electrodes, make sure that they are not too dry. And we don’t have to, not if we pay attention to five basic elements of our technique: current setting, length of arc, angle of electrode, manipulation of electrode and speed of travel — or CLAMS, for short. It required expert labor. Poor FusionProper fusion means the weld must physically bond strongly to both walls of the joint and form a solid bead across the joint. Stick welding is used for the welding of most common metals and alloys effectively. Use a uniform travel speed and avoid excessive weaving. In addition, steels with high sulphur and phosphorus contents are not recommended for production welding. Techniques include lots of things...not just the way you move the rod. They make it look easy. An unknown error occurred. Limit side-to-side motion to two times the diameter of the electrode core. (Electrode positive provides about 10 percent more penetration at a given amperage than AC, while DC straight polarity, electrode negative, welds thinner metals better.) To overcome shallow penetration, try higher currents or slower travel. To cover a wider area, make multiple passes or use stringer beads. This is known as the drag or backhand technique. However, it’s still commonly used on construction sites or for repairs and maintenance. Be sure to keep the puddle molten for a longer time to allow gases to boil out before it freezes. Feather edge preparations require a slow costly seal bead. 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. If you’re welding with amperage set too low, your electrode will be especially sticky when striking an arc, the arc will keep going out while maintaining the correct arc length or the arc will stutter. When welding on 10 to 18 gauge sheet steel, the fastest travel speeds are obtained with the work positioned at a 45 to 75 degrees downhill angle. There is also a high potential for undercut. Here are the three most used welding techniques/patterns: Whipping the rod, a moving it back and forth motion.
