Shielded metal arc welding or SMAW welding is one of the most common methods of welding today. It is also sometimes termed stick welding because of the fact that it utilizes an electrode rod or “stick” in order to produce an electrical arc with a very high temperature that can melt metal. The electrical supply can either be in the form of direct current or alternating current. The electrode is consumable in this case and is the one used to create the weld on the material.
The electrode is also coated and this coating becomes vaporized as the electrode is melted. This gas becomes the shielding material to shield the weld from contamination from the air surrounding the working area. Stick welding is very popular for several reasons. First of all the process is easy to learn and master. It is effective in welding steel and iron and other common metals used in the welding industry. Finally the equipment in this form of welding is relatively cheap and easy to use.
This type of welding is the most extensively used in most applications related to welding in most industries. It has certain advantages over other forms of welding as well. It can be used to reach isolated working areas or spots that have limited access, it can be used for underwater welding, the electrode used in this form of welding also provides the shield at the same time, and it can be used for welding from different positions.
Here are some tips that you can keep in mind when you want to do some stick or SMAW welding:
1. The first important step that you should take when you are performing stick welding is to get the right kind of machine. Make sure that the machine that you will be buying or using can produce the right amount of current for the material and electrode that you are going to use. There are many manufacturers of welding machines today. Be sure to find the right one that will suit your needs.
2. You also need to pick the right sort of electrode for your use. Make sure that it will be a good match for the kind of work that you will be performing. There are many types of electrode that are available for different applications, uses and materials. Check to be certain that you are using the right rating of electrode for the kind of work that you are trying to finish.
3. Clean the surface that you will be working on before you start welding. This is always a good thing to help make sure that there will be no defects in the weld that you are working going to perform. This is actually less important with stick welding than with other forms of welding that are used today, but preparing your material carefully can go a long way in making sure that your finished work will be of the highest quality. It also shows true professionalism and attention to detail which are always valuable skills.
4. While you are welding make sure that you do not pull out the electrode too fast so that it loses contact even before the weld is finished. This is where the art, or “feel” for welding comes in. The good thing is that practice makes you better at adjusting the rate electrode delivery for best performance.
These are just some of the tips that you should keep in mind in order to get your stick welding or SMAW welding to be of the highest quality and keeping it at that level. SMAW welding is a crucial skill to master for any welder worth his salt, and it will increase your value in the trade too.
