Stick welding- the most popular welding process:

Wednesday, September 29th, 2010

Stick welding is the most popular welding process because of its versatility and its simplicity. It is a manual arc welding process that uses a consumable electrode and it is extensively used in steel structures and industrial fabrication. It is the most dominant welding process that is used to weld iron and steels, but other metals such as aluminum, nickel can also be welded. Stick welding gain its popularity from 1960s and the manual welding uses different flux coatings designed to work with specific types of steel and welding applications. This is called as manual welding because it requires the operator to handle the torch.

The choice of electrode for SMAW depends on a number of factors, including the weld material, welding position and the desired weld properties. Manual welding uses different flux coatings designed to work with specific types of steel and welding applications. Stick welding is the choice to weld stainless steel and this method of welding utilizes equipment that is typically the least expensive. The stick welding will require the weldor to remove the slag residue from the cooled weld by chipping it away with a hammer and cleaning it with a wire brush.

How to improve stick welding?

Monday, September 27th, 2010

DC welding is considered best for stick applications due to following reasons:

• Easy to start
• Less spatter
• Easy vertical up and overhead welding
• DC provides 10 percent more penetration at a given amperage than AC
• DC welds thinner metals better

A 225 to 300 amp welding machine handles almost anything the average person will encounter, as most stick welding procedures require 200 amps or less. Duty cycle is the number of minutes out of a 10 minute cycle a welder can operate. Duty cycle and amperage are inversely proportional. The type of rod that is used for welding are hard facing rods as it can provide resistance, abrasion resistance or both depending on the application. Stick welding is more forgiving on unclean conditions, but it never hurts to clean parts with a wire brush or grind off excess rust. If you prepare well and have average welding ability, you can make a sound weld.

How to stick weld?

Wednesday, August 18th, 2010

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.

Where are stick welding used for?

Friday, June 25th, 2010

Welding 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.

The Multiple Uses of Stick Welder

Wednesday, April 28th, 2010

A 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, 2010

Learning 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.
