Stick welding is known as manual metal arc welding or shield metal arc welding. This is very popular form of arc welding. Select the steel to weld. Steel should be in plain carbon steel with less than 1 percent carbon, less than 0.1 percent silicon and 0.035 percent sulfur. Find the joint position based on the thickness of the metal. This angle should be lower for thicker metal with a 45 to 75 degree angle being best for 10 to 18 gauge steel. Make sure that joint geometry is correct. Width should be consistent for the entire joint. Clean the joint before welding to attain the best travel speed. Use the largest electrode that is practical. This is generally 3/16 inch for overhead and vertical welding while 5/32 inch is usually the maximum size for low hydrogen applications.

• Make sure that you are working in a well ventilated area
• If you are a heart patient and having pace maker, then consult your physician before you going for work
• Do not make any body contact with plasma arc cutting system
Plasma arc cutting is an easy process if you follow these safety precautions
MIG welding wire types
Monday, June 28th, 2010In metal fabrication and production, the MIG welder is commonly used owing to its versatility and efficiency. To control the amount of filler metal added to the weld puddle, the MIG welder uses welding wire fed from a spool. Diameter, alloy and type are used to categorize the MIG wire.
It is necessary that the alloy of the MIG wire must match the base metal being used. This would ensure that a strong weld would not crack or weaken when cooled. As a wide variety of alloys are available for MIG welders, welder would have the option to weld carbon steel, stainless steel and aluminum. A MIG welding wore would have the name of the alloy, diameter and type of the wire marked on a label. The label would be visible while attached to the welding machine as it is located on the side of the wire spool. Even though the wire type would be marked on the label, each manufacturer has a different way of making wire type. The two distinct type of MIG welding wire are the solid core and the flux core. Solid core MIG wire is a solid strand of the chosen alloy while the flux core MIG welding wire has a flux paste inner core would be surrounded by the filler metal.
Where are stick welding used for?
Friday, June 25th, 2010Welding makes the work easy and many people relay on this for welding. The process of using covered electrode is known as stick welding. It is other wise known as Shielded Metal Arc Welding (SMAW). This is more commonly used by the people than other arc welding. That’s because these are flexible and also versatile. These are known as versatile because they can weld metals together very fast. These are easy for welding once you practice for it. These are generally used for small repair work around the house of individuals.
The merit of this welding equipment is that these are inexpensive than other welders. These are very smooth and comfortable to use and are also portable for welding. The flux in most of the welding equipment needs regular regulating. But these don’t need regulating because here the electrode does this work. These are very less susceptible from any kind of wind and drafts. These can be welded from any angle or position for welding metals.
What is the use of arc welding?
Friday, June 11th, 2010Arc welding is one of the easiest among other welding process. This is other wise known as stick welding. The technical name given for this welding is Manual Metal Arc Welding (MMAW). The arc welding is easy to handle and is simple enough to understand. The job of this welding is to transform electricity. The arc welding works only when electric arc is kept between two pieces and electrode. The actual voltage given by the arc welding while working is only 20 volts.
The merits of arc wielding are:
• This welding is inexpensive and is easy to handle.
• This requires less space and is portable for carrying.
• This doesn’t need auxiliary gas for shielding.
The demerits of arc welding are:
• The electrode has to be replaced every now and then.
• You need to remove the slang from the welders.
• The deposition rate is lower than the electrode process.
The Multiple Uses of Stick Welder
Wednesday, April 28th, 2010A stick welding is something that we can learn it so easily and is very much useful in a lot of places. Stick welding or the Shield metal arc welding is a manual arc welding process in which a consumable electrode coated in flux is used to make the weld on a surface.
DC welding will make the most benefit over AC for almost all the Stick applications, which includes trouble-free starts; less arc outages along with sticking; a smaller amount spatter or even neat looking welds, easier vertical up as well as overhead welding and you can also learn easier to weld, and a smoother arc.
In case of DC reverse polarity or the electrode positive offers about 10 % additional diffusion at a given amount of amperage when compared to AC, at the same time as DC straight polarity or the electrode negative welds that gives thinner metals, better the output.
Choosing A Proper Electrode For Stick Welding
Wednesday, March 3rd, 2010Learning welding is not an easy process without having interest on the art. You can easily learn the skill when you practice it with involvement and creative ideas. Same way learning to do stick welding also needs a lot of take practice and a little of patience to be trained in a way that will create fine welds.
Being one of the fundamental techniques of welding, stick welding is easily learnt by a lot of students and people who had just started as beginners who are learning welding for personal use.
The main thing anyone should remember before stating of with the welding lesson is to learn and analyze the uses and problems of different types of electrodes that are being used.
Choosing the right electrode can be one of the best ways to achieve fine welds as planned and required. Many are not aware about the size of the electrode that they must use. The point to be noted here is- The size of the electrode depends on the position you are welding within.
In this condition the welder will be struggling against the gravity if the weld is done upright (vertically). So, in this case a welder should wisely choose to do the weld with an electrode that is AWS classified as 7018 for the reason that it is low in powder content.
An Overview for Manual Metal Arc Welding
Friday, February 5th, 2010Manual metal arc welding technique was discovered in Russia during 1888s. This technique of welding is also termed as shielded metal arc welding (SMAW) or stick welding. The process of welding first starts by striking an arc between the base materials and the consumables electrode rod. These rods are made up of steel and it is covered with a flux and the weld area is protected from the oxidation and contamination during the welding process.
During the process when an arc is struck between the electrode and work piece materials the surfaces are melted down into the weld pool. And a coating is formed around the rod by melting down the flux. This melting of coating forms gas and slag to cover the weld pool from the surrounding environment. The speed of welding is relatively slow in this process because more often the welder has to replace the consumables rod and has to chip down the weld bead once the welding is over. This process of welding can also used to
weld other metals too.
The stability of arc formed, depth of penetration, the amount of metal being deposited totally depends on the position of welding and amount of coating provided on the electrode during the welding.
What You Should Know About Stick Welding
Sunday, April 26th, 2009If you need heavy duty welding done such as steel construction for building or even for machinery repair, you should look for a stick welder. The stick welding process is one of the most popular of them all. This procedure actually makes close to all of the welding done in some countries.
Those who are looking for welders are usually hiring officials in the construction industry. There are some that are sought out for many other industries like manufacturing positions too. The stick welding process is one that will be around for many years to come. There is a need for those that can stick weld in places a machine cannot.
It is the stick welding process that is uncomplicated in how it is done and the equipment needed is very easy to find. This process is mainly for those who need to weld iron products or steel metals, in order to gain the manufactured product they seek.
An Overview of Shielded Metal Arc Welding (SMAW)
Tuesday, January 20th, 2009SMAW welding, otherwise known as stick welding is a process that many welders use because it uses an electrode that is covered. This is called the “stick” and it is one of the least expensive ways to weld.
Stick welding is one of the most popular ways to weld today because it is easy to do and the welder can control it. The stick has flux coated on it so the welder does not have to worry about keeping flux on hand.
How It Works
The way this works is that as the stick is heated, the flux melts. The individual then controls the weld as they work their project and the flux and the stick form a gas and slag that shields the arc that is made. In this way the weld pool stays clear of the molten metal.
The Advantages of Stick Welding
Stick welding is one of the easiest methods to use and the equipment cost is nominal. Because the electrode is already covered with the right amount of flux you do not have to regulate it. You can use this method in any position and it is easier to work with in winds and drafts.
The Disadvantages of Stick Welding
There are a few things that can happen to cause problems if you do not catch them ahead of time. One of the challenges with stick welding is that you can get spatter on your metal. This doesn’t look good and it can be difficult to clean. If you have a metal that has tension or fatigue in it undercutting can be a problem. You may need to start over with your piece you are working.
Sometimes when you are trying to make your weld, your arc can become erratic. This is usually a sign that your electrodes are wet and you will have to get a different stick.
The good news is that these disadvantages can be fixed by paying attention to what you are doing. If you find yourself in a jam and you are not sure what to do, the Internet has a wealth of information on stick welding.
How To Make A Strong Stick Weld
There are many things that you can do to avoid the disadvantages. Make sure that you clean the metals to be welded before you start. Be careful of your buildup so you don’t over do it.
