The process can be used in all welding positions depending on the type of electrode.There is almost no material for which stick electrodes cannot be used for.Outdoor welding possible (even in rain and wind).Good shielding effect of the weld pool can be achieved without gas.Of course, you should clean off the slag from each weld before continuing or making multiple passes. Do not directly touch the welds – aim your hammer higher. Getting the right travel speed will take time and practice.įinally, if your welds continue to fail, it may be a good idea to test them with a hammer to make sure they are strong enough before you put your gear away. Move too slowly and your weld pool will build up, giving you too much weld deposit. Move the electrode too quickly and your welds will be narrow and inconsistent. If you are not getting good penetration, it could be due to several factors including movement speed. Working on the most suitable arc length will help with this read the manufacturer’s specifications and industry guidelines for more details, but electrodes with a diameter of 1/8″ or greater generally require a 1/8″ arc length, while an arc length of 1/16″ works best for smaller electrodes. To fix it, you just need to start over and make sure you stay the same distance from the joint. This happens when you move the electrode too far away from the metal. Once you are in the process of starting, your arc may break if you do not move the electrode smoothly and evenly. Don’t panic! Just twist the electrode slightly and it will relax for you to try again. When you try to start your arc, your electrode may get stuck to the metal. An arc will form between the metal and the electrode and the two will begin to melt. To start the arc (and hence the SMAW welding process), you only need to scratch the electrode strongly against the surface of the metal, then pull it away slightly. Then insert the chosen electrode into the welder and select the appropriate amperage (read the manufacturer’s directions if you are unsure of this) and you are ready to weld. Make sure your metal is clean as any dirt and imperfections can affect the strength and quality of the weld. Besides the blinding light of the arc and the heat generated by this process, you must be properly protected from any slag and spatter that forms. Stick Welding Processīefore you start welding, it’s essential to get your hands on a mask and other protective clothing, including jackets, and even boots. This process also forms a layer of slag that must be chipped off – making it slower than many other types of welding – but choosing the right electrode can help speed up the process. This eliminates the need for a separate shielding gas tank – otherwise, the welds would be brittle.Īs the weld pool cools, it solidifies to form a seal. At the same time, the heat of the arc burns the flux, which forms a gas layer that protects the weld from certain atmospheric gases, which can affect its quality. Trusted Source Molten Weld Pool - an overview | ScienceDirect Topics The welding machine is connected to a power source that creates alternating current (AC) or direct current (DC) to form an electric arc between the electrode and the metal.Īs this arc forms, the electrode and metal melt to form a molten puddle called a molten weld pool SMAW welding is a process that uses consumable electrodes covered in flux. This is a relatively straightforward process because it uses simple equipment and is relatively easy to learn. , manual metal arc welding (MMAW), and flux shielded arc welding, stick welding is a welding process that is quite popularly used around the world. Trusted Source Shielded metal arc welding - Wikipedia What Is Stick Welding?Ĭommonly referred to as metal arc welding, SMAW In this stick weld vs MIG comparison, you’ll find out about the advantages and disadvantages of both processes and when you can use both techniques. Today, we want to talk about stick welding and the MIG welding processes. However, there are several arc welding station technologies (stick, MIG, and TIG) for joining up these metals. This is the only reliable method for a durable weld because it produces the heat necessary for the proper fusion of metals.Ī welding station is used for welding iron, stainless steel or aluminum. Learn more about our process hereĪrc welding consists of creating a short circuit that causes an electric arc as well as a very strong source of heat.
