But know that have been practicing I cant seem to get the bead to flatten out like it does running in the flat postion, I dont know for sure it is dropping but it does not flatten it got hump in the middle of the weld. And on other question on gettig certified. I work for an awning compay and we have been getting into bigger stuctures such as 10x10 coloms and they want everybody to be certified but at the shop the foreman doesnt buy or rod we only use or can you get certified using that rod.

For many contractors, stick welding is at the heart of their business. Over the years, materials used for structural applications have continued to lend themselves readily to the process, making the use of filler metals like AWS American Welding Society E stick electrodes a prominent choice. These stick electrodes provide the chemical properties necessary for the applications, along with the low hydrogen levels needed to prevent issues like cracking. They also provide the appropriate mechanical properties for these jobs — most steel used for structural applications A, for example requires filler metals that offer 70, psi of tensile strength. E stick electrodes meet those specifications. As with any part of the welding process, knowing the basics about E low-hydrogen stick electrodes can be helpful in understanding their operation, performance and resulting welds. To help along the way, consider these details. Characteristics As a general rule, E stick electrodes are a good choice for structural steel applications due to their smooth, stable and quiet arc, and their low spatter levels. They also offer good deposition rates, allowing welding operators to add more weld metal into the joint in a relatively short amount of time. This characteristic is made possible by the addition of iron powder to the coating of the stick electrode.

Safety glasses, a proper helmet, gloves, long sleeves, and leather or fire-retardant clothing are a must see Figure 4.

Figure 1 SMAW, or stick welding, requires a certain mastery of skills, and vertical and overhead stick welding is that much more difficult-one of the reasons the specialty is in such great demand. Vertical and overhead stick welding have never been in such high demand. Heavy construction continues see Figure 1 in the southeast U. Ironworkers, pipe fitters, boilermakers, and shipbuilders are working to meet a new global demand for development and energy. At the core of this work lies an advanced welding position that requires skill beyond the preferred horizontal position—vertical-up shielded metal arc welding, or stick welding. Flat and horizontal welding positions lend themselves to faster work, but sometimes vertical or overhead welding with a stick electrode cannot be avoided. If that's the case, here are five tips to help you do it well.

The weld metal and the slag drip down uncontrollably, along with increased sparks and spatter. The proper term when you weld upwards is vertical-up welding, but we also call it uphill. You can stick weld vertically, depending on the welding rod you use. After that, the puddle is too large to control. The excessive iron creates a large and very fluid puddle that cannot stay in place.

When it comes to welding with the electrode in the vertical position, several factors play a crucial role in achieving a successful weld. Let's discuss the importance of amperage, polarity, arc length, and rod angle in this context:. Overall, paying attention to amperage, polarity, arc length, and rod angle is helpful for vertical welding with the electrode. Stronghand Tools. Tig Fingers. Tig Kits.

There are other brands that do well on structural welds but not on pipe welds. The KEY is having enough amps, good dry rod and a real tight arc. I respectfully disagree on the Excalibur comment but agree on the Atom Arc. Always consult with the specifications for the job beforehand. Elliott, the Esabs are a good choice. Run about amps. The base metal thickness can make it difficult too. Then it comes down to how the arc is positioned in the weld pool and how long it's held there. If you're new to stick welding and you're finding as soon as you start your vertical stringer that everything just goes to hell, you might not necessarily be ready yet, it's hard to learn when you don't know what you're doing wrong. Another benefit is that someone certified in vertical welding is automatically certified in flat and horizontal welding. One error to avoid while weaving is undercutting. Heavy construction continues see Figure 1 in the southeast U. To protect from moisture damage, it is important to keep that package intact until the products are ready for use.

And if a WPS specifies stringer beads as opposed to a weave, then you need to use stringer beads. Personally, I prefer a weave in most cases, but I have been on jobs where stringer beads were required.

Also yes, I'll do a bead plate this weekend as well in flat position. What is the secret to vert up? Of the five welding positions—flat, horizontal, overhead, vertical-up, and vertical-down—vertical-up is the slowest because the welder needs to combat gravity. Welcome back! Categories Additive Manufacturing. Thats why ihave been practing at the house with and still need more pratcice hence all the question. The extra heat helped the bead flow more, so you get the softer look to the ripples as well as making the bead flatter. Maybe my travel speed is too high? Focusing on stringers now but want to perfect my lap joint. For vertical I started out at around but that seemed too high and was getting what I thought was dripping metal maybe it was just slag now that I think about it.
