Traveling too fast will create a thinner/undersized bead that will have more of a V-shaped ripple effect in the puddle rather than a nice U-shaped, or stacked dimes, effect. This can lead to excess spatter and higher potential for undercut. If you have trouble seeing, move your head, rather than lengthening the arc. If you are stick welding / arc welding and If you have an unusually big gap to fill,... Don’t fear the amperage. Any variations in a given joint will force the operator to slow his or her welding speed to avoid burnthrough and manipulate the electrode to adjust for the fitup variation. Welders find welding in the vertical and overhead positions hard to learn and implement too. The rest of us may struggle with it, though. Sign in / Create Account. Choose a Joint Position and Electrode that is Conducive to the MetalJoint position can have a great affect on finished weld quality. If you are welding with low-alloy steels and carbon steels with chemistry compositions above the "normal range", they will have a tendency to crack, particularly when welding on heavy plate and rigid structures. Tungsten inert gas (TIG) welding requires more skill and takes longer than MIG … Sufficient bevel is required for good bead shape and penetration; insufficient bevel prevents the electrode from getting into the joint. Why? In general, weld seal beads on flat work with 3/16" AWS E6010 at approximately 150 amps DC+. Circles to fuse the metal in a circular motion. In addition, the electrode will become hot — perhaps hot enough to glow toward the end of the weld—which can adversely affect the shielding properties of the flux. Optimize your operation through advanced welding processes, training and weld data monitoring. Proper joint geometry is based upon some simple principles: 4. A light drag technique is recommended for low hydrogen electrodes. 6. 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 vertical up, if you focus on welding the sides of the joint, the middle will take care of itself. As a good starting point, arc length should not exceed the diameter of the metal portion (core) of the electrode. This reduces the amount of alloy added to the weld from melted base metal, On multiple pass or fillet welds, be sure the first bead is of sufficient size and of flat or  convex shape to resist cracking until the later beads can be added for support. This is known as the drag or backhand technique. This article will offer tips that you can follow to increase your chances of creating a high quality stick weld - right from the start. Sometimes the sulfur content of free machining steels can be high enough to prevent successful welding. If possible, weld toward the unrestrained end. The correct amperage setting primarily depends on the diameter and type of electrode you select. Traveling too slowly produces a wide, convex bead with shallow penetration and the possibility of cold-lapping, where the weld appears to be simply sitting on the surface of the material. Other welding techniques offer the same result; the difference is in how you go about it. Poor FusionProper fusion means the weld must physically bond strongly to both walls of the joint and form a solid bead across the joint. If there is too much heat input you get burn through. 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. Stick welding uses electricity to melt the filler metal rod or the electrode as it is properly referred to. The Angle Of The Torch. Hot tips and tricks for stick welding - more Stick Welding tips Using an extra rod to fill gaps,. This article will cover basic welding techniques in "stick welding. When welding from left to right, maintain a 0 to 15-degree angle tilted towards the direction of travel. The weld is the result of too much current. For full- strength welds, penetration to the bottom of the joint is required. To correct poor fusion, try a higher current and a stringer bead technique. Remove the cigarette lighter from you pocket. Stick welding is a difficult but exciting process. Stick welding in the flat, horizontal and overhead positions uses a drag or backhand welding technique. If you are new, practice to learn it. Sign in / Create Account. For those of us that are experienced welders a 3F or 3G vertical up with SMAW can still […] The electric arc provides excellent weld penetration, which makes it ideal for use on thicker metals. Note that on material 1/4 inch and thinner, weaving the electrode is typically not needed because the bead will be wider than necessary. Length of arc: The optimal arc length, or distance between electrode and puddle, is the same as the diameter of the electrode (the actual metal part within the flux covering). The torch must be at least 15-20 degrees away from the surface material … To control a wandering arc, the best option is to change to AC welding. Begin by removing scale, rust, paint, moisture and dirt from the joint. Here the welder uses a semi-circular motion to create a wider bead with a stacked dimes appearance. Minimize admixture of base metal into weld metal by using low current and fast travel speeds for less penetration. Learn the five basic elements of stick welding technique to significantly improve your stick welding results. Don’t get discouraged! But it’s a good starting point. However, if you pause for a brief moment after every few triangles you will get better penetration and fusion. If the molten metal is running in front of the arc, change the electrode angle. An arc length that is too short will create greater potential for the electrode sticking to the base material. Experienced welders who can pick up a stinger, pop an electrode in and lay down great welds time after time can inspire great awe in the rest of us. Lack of fusion is often visible and must be eliminated for a sound weld. To eliminate undercut, reduce current and slow travel speed, or simply reduce size until you have a puddle size you can handle. This can result in insufficient penetration in those areas.
