The Stick Rod Series – Fast Freeze Rods

Published

on

Hello again I hope this article finds you without burnt eyes or some other welding trauma. You can prevent this by staying behind the welders lens. Today we are going to start our discussion about the anatomy of stick rod or arc welding with flux coated rods (electrodes).

Of course there are many types of stick rods but the best place to start is with a fast freeze rod. Fast freeze rods are in a category that has been the foundation for stick rod welding. They are still an industry standard in many places. I have worked for companies that don’t use these rods in their process as a root metal, but most do. When we talk about root metals we are talking about those metals that are always the first metals to be applied to a weld joint, whether it be pipe welding, plate welding, tube welding, structural welding, etc.

When we speak of this type of rod we are almost always talking about basic carbon steel (also known as black iron or mild steel). Fast freeze rods have the ability to cool rapidly even while the weld process is in motion. Imagine stacking dimes on top of one another with slight overlap from one dime to the next. Like a row of fallen dominoes Now this of course would be a flat continuous weld. Each time in welding with a fast freeze rod the rod is moved slightly forward and then back into the original puddle. As soon as you move forward with the stick rod the metal that has been deposited behind the rod is already becoming solid thus applying the term fast freeze. There is some ability to drag the rod without a great deal of movement, but because of the nature of the rod and its design, it wants to solidify rapidly so to prevent a great deal of build up when depositing the metal, you will naturally move the puddle more than some other rods.

The tighter the laying of one dime upon the next signifies good weld continuity. One thing that must be observed with this application is the tendency to undercut the areas of existing weld joint with the new metal that is being laid on top of it. When you step the rod out of the puddle, the area you move ahead to is being dug into by the action of this rod. That is why you step the rod back into the last dime of weld filling in the areas that have been dug out by the rod as it was moved ahead.

This type of rod has a great digging effort with it. One tip of advice about this type of process is this: “Don’t be afraid to leave enough metal in the existing weld path before moving ahead. Beginner welders especially have the tendency to move ahead to fast before depositing enough metal to prevent undercutting the parent metal (existing metal). Undercutting is a term that simply means the weld metal that has been deposited was not enough to flush out the weld with the surrounding surface. Normally, the weld deposited from the rod is enough to make the new weld higher or fatter than the original material.

When the metal deposited during the welding process is shy or not enough, the newly deposited metal leaves a jagged edge next to the new metal instead of a nice rounded effect. 6010 electrodes, 7010 electrodes, 8010 electrodes, shield arc 85, 6011, 6013 are all fast freeze rods, just as some examples. These rods are designed to dig into the parent metal and give good penetration. It is good on rusty metals and metal that is not very clean. Old material that has corroded over time, etc.

One trick you can apply with this type of rod is this: The polarity can be switched when welding this rod allowing for less penetration or digging as it is being welded. Sometimes on thin metal or metal that cannot hold up to a great deal of scouring effort by the norm of these rods can be overcome by this little trick. Make the ground positive and the hot lead negative (reverse polarity). You will find that the sound is a bit different while welding than it normally would be. You will also find that the welding rod does not have the tendency to dig or penetrate as much.

This is a trick that comes in handy, especially when working on thin metals. I have found for myself that these rods run smoother on a slightly higher heat than you might feel comfortable with. Running a hot puddle is better and becomes easier to handle the more you practice with it. These rods can be run either uphill from bottom to top on a vertical plane or top to bottom on a vertical plane. There is more movement usually on the uphill and more dragging or leading on the downhill. They are actually all positions rods. Flat, overhead, vertical, horizontal, Arkansas bell or 6g which incorporates all of the positions within the weld path. Normally any pipe test you will ever take will be in the 6g position. There are some exceptions. One of the tests that I never liked taking was a fixed jig test. This test simulates an actual field weld that will have to be made on the job. They can be a nightmare.

Heat, travel speed, and rod angle are the 3 most important factors when welding with stick rod. I said heat, travel speed, and rod One thing that does not usually hurt the stick rod category is wind. It has to really be blowing in order to hurt the fast freeze series of welding rods. Some of the rods I mentioned earlier are AC rods and some of them are DC rods. Keep that in mind when choosing your rod. I have another article coming on that. Well that’s all the time on this article. Thanks from the author.

MapleStory Guide – Anego

Published

on

By

Anego (aka Female Boss) is a popular boss in Showa. It spawns in the third map of the Showa mansion, surrounded by its vastly weaker minions. It is a formidable foe, with very high attack power, defence and speed.

So let’s have a look at what Anego’s capable of. Anego has two main attacks plus a rather high touch damage of about 10,000-11,000, a fairly long range gun attack dealing around 5,200 and lastly, a short range slap dealing roughly 18,000. If you’re melee without a ridiculous amount of hp washing, then I know what you’re thinking. Some other things about Anego, it has very high defence and moves extremely quick.

So with such high damage how does anyone kill it? Luckily Anego suffers a “glitch” so to speak, which will be explained in detail below.

HP: 75,000,000

Minimum HP: 19,000 (Melee) Any (Ranged)

Now to talk about that “glitch”, if you attack Anego and run back to the portal, you’ll notice Anego is unable to follow all the way to the left. This is due to a pathing issue in the maps layout, near the edge of the bar stool is an invisible barrier for Anego, which it is unable to pass. Obviously that makes the entire left side a perfect sniping spot! Basically every single ranged class can make use of this and this is also the basis for party kills of Anego. The spot where you’ll want to stand is directly in front of the couch near the portal, if you edge past this you may be hit by Anego’s gun attack, but the slap will miss you by miles.

For melee it’s not so easy, the only viable way to fight Anego as a melee character is to corner it and tank it, burning potions while pounding away. Obviously you need 19,000hp before even considering this.

As a side note, it is possible to berserk Anego as a Dark Knight, but is difficult to do effectively. Lure Anego to the bar stools, and attack while jumping. If timed right you will not be hit by the slaps while still hitting Anego.

WoW Bot – InnerSpace Guide

Published

on

By

First off, I’d like to explain some terms. Innerspace is an operating system, not a bot. Many people will be peeved if you say that. Openbot is a program/plugin/whatever that runs on innerspace. Openbot is a bot. Get these down and you’ll save the openbot vets some hair.

Innespace is NOT free. And I did’t find a crack yet. Yes you will need to pay for it if you’d like to use it. It will cost you $10 for a 3-month subscription. This is cheaper than glider elite. If you’d like to subscribe to use this bot Lavishsoft.com register an account, and subscribe from there.

Once you have an account subscribed, you can start this guide.

-Setting up Software-

1. Download and install the latest version of Innerspace.

2. Download the latest version of ISXWoW and ISXWarden. Always keep these up to date!

Install ISXWoW by running the installer if you downloaded that, or if you downloaded the zip, extract ISXWoW.dll into the Extentions folder and the other files into your Interface folder.

Install ISXWarden by simply extracting the .dll to the Extensions directory of your Innerspace installation.

3. Launch innerspace, right click on the little crosshairs icon, and click configuration.

4. Click on the “Game Configuration” tab and select World of Warcraft from the dropdown menu. Click Startup.

-Ingame Openbot Setup-

1. Once Innerspace is loaded with WoW and you’ve checked ISXWarden to be okay, log ingame and bring down console again.

2. Type into console:

run openbot/openbot

This should load the ingame interface.

Going into the rest of the steps for Openbot Configuration takes a lot of detailed explanation. By way of a quick search, you would find that the full steps are available at most sites offering WoW Bot and other gaming tools.

Whistler Via Ferrata – Terror And Elation While Climbing The Iron Way

Published

on

By

“Okay, we’ll stop here and pull out our ice axes and crampons,” announces Jeff, our guide for the afternoon. He slides off his backpack and dumps it in the snow at his feet. I shrug my pack off and marvel at how I can be so warm while standing at the foot of Whistler mountain’s high alpine glacier. True, back at the Adventure Hut I had added a few layers of clothing after noticing the wisps of snowflakes drifting from the sky.

But now, an hour later and a brisk hike among the white-laced rocks, I was sweating. I ask my best-friend Amy if she’d like a swig of water. She nods and I dig the bottle out of our pack. I also pull out a couple energy bars to quell the rumbling in my stomach. I must have anticipated it would be a few hours and a few hundred feet until the next meal.

You can’t find this quiet anywhere near civilization.

Amy and I munch loudly in the natural stillness. It’s the silence that allows you to finally hear what every other animal must hear, every insect, as they go about their business in the absence of human activity. It feels as old as the earth and indifferent as the mountain itself.

Jeff instructs us on fitting our crampons; basically spiked metal shoes that are essential for glacier-walking. I’d never heard of them before this moment – before we’d decided to attempt Via Ferrata, “The Iron Way” – a tour offered by Whistler Alpine Guides Bureau. First developed by Italian soldiers during World War I, the activity consists of rock climbing via an engineered vertical pathway, utilizing permanently fixed cables and metal rungs for movement. (Or that’s how it works in theory anyway).

All three of us tie each other together with elastic rope. “In the fresh snow, it’s difficult to spot the crevasses in the glacier,” says Jeff. I envision a moment of plunging into an icy abyss and make sure my the rope is tightly clamped to my waist before we head out. Our crampons dig into the ice with assuring crunches. Like a blind man with a cane, Jeff pokes his ice axe in the snow to detect any cracks.

Soon we are standing at the foot of the climbing path.

A lone ladder is tied to the rock, stretching upwards to the first ledge, followed by metal rungs continuing upwards as if staples left by a giant. We remove our crampons and secure our ice axes to our backpacks. Jeff graciously goes first, gliding up with ladder with only the barest use of hands. Amy goes next, a little slower. I wait at the bottom of the ladder, peering at the surrounding boulders for any glimpse of the hoary marmot, (for which Whistler Mountain was named), known for its distinctive high-pitched whistle.

The ladder quivers. I look up and Amy is perched at the top, one hand outstretched to the first metal rung. She’s hesitating. “You okay?” I call up to her. “I’m not sure about this,” she answers flatly. “I don’t think I can do it.”

Jeff is a few feet higher, hanging from the rock like a confident gibbon. “It’s cool, just take your time,” he says. I wonder how many times he is confronted with this exact predicament. “My heart is pounding…” Amy answers, her voice cracking. Jeff is reassuring. “It’s quite safe, really. You’d be surprised at what you can do.”

There’s a defining moment in the air.

Amy must choose whether to attempt the shaky descent down the ladder, shrink from the pounding of her heart, and feel like she’s ruining the experience. She’s skimming over in her head how she’ll walk back down the glacier in stinging defeat, head to the Adventure Lodge and wait for us to complete the climb.

Jeff and I will arrive, tired and elated, and we’ll talk about how incredible it was to scale the peak, to feel the hard stone beneath our fingers, marvel at the tiny plants that make a home on these eternal stone. I’ll tell her how the vast view of the surrounding mountains was enough to silence any internal debate about the existence of an intelligent hand guiding the universe, or if not intelligent, than the incredible luck to emerge on a small beautiful ball drifting in a beautiful universe.

But Amy doesn’t choose such a fate for herself. She quells her beating chest, strengthens her resolve. She firmly grips the first metal rung, that giant’s staple lodged in the rock, and pulls herself over the lip, her feet dangling for a second before gaining a toehold. Fear and gravity are thwarted. She looks back down at me and smiles.

I climb the ladder and feel a bubble of adrenaline rise in my throat. But whether I’m aware of the true danger, or I possess a certain flare for attempting the unordinary (which happens less often then I’d like), I have little difficulty in crossing the threshold. All three of us begin our climb. The basics: always keep your belt ropes clamped on the safety line running parallel to the metal rungs, and only one person per increment of safety line. This prevents falls for more than 6 feet at once. A comforting thought.

Unhook, reach, lift, hook. Unhook, reach, lift, hook.

The steady rhythm takes on a momentum of its own, almost like meditation. I immediately understand why frequent climbers talk about being “in the moment” while scaling a sheer rocky face. There is little to think about when the mind must navigate an ever changing vertical terrain, constantly readjusting weight here, balancing a foothold there, like deciphering a rubix cube. The minutes drift away and the glacier below grows ever smaller.

Eventually, we arrive at the summit. The clouds part and the sun greets us warmly. We wander among the snow drifts as if emerging into another land, as if explorers entering the gates of Shangri-la. Only there are no gold tapestries, chests of jewels, or eternal youth here, only the satisfaction of conquering a thumbnail of earth on one Saturday morning in September.

~ Via Ferrata is offered in Whistler daily from June 24 through October. This thrilling activity is suitable for guests of all abilities and does not require any special skills or prior experience. All technical equipment is included. Your guide will give detailed instructions on use of equipment and technique for climbing.
