Common welding mistakes which you need to avoid



Welding is the process which involves joining different materials together. Unlike soldering and brazing, during welding a good amount of 'melting' of the metals take place while fixing them together. Ususally thermoplastics or metals are used in the welding process.

Like any other sphere of work, welding too requires an indepth understanding of the basics. There are some mistakes which are commonly committed in the welding process. Right from using the wrong voltage, to creating an arc way too longer than is required. Logos Weld Products is one of the leading welding electrode plant supplier in India. With years of experience and expertise, here is a list of mistake which needs to be avoided in the welding process.

Mistake #1 – Making the arc outside the weld joint


Striking is not an easy task, more so in case of beginners, due to which several times it is seen that the arc is striked outside the weld joint. The best way to avoid this situation is to begin from the point you plan on welding. This way not only will you avoid striking in the wrong manner and also bring down the risk of damaging the other parts of your work piece.

Mistake #2 – Using the wrong current for welding


Yet another common mistake, often it is seen that welders use the wrong current in the welding process. You just need to take the type of metal and electrode into consideration, and it becomes easier to decide which current to use (DC/ AC) and the quantity of current to be used. If you are a first-timer, it is recommended that you cut some scraps of the metal and test it with your settings. This way you will get to know which is the right current for that particular metal.

Mistake #3 – Using electrodes which are damaged


It is very important that the welding electrode plant is not damaged in order to get the results you are looking for. A MIG wire with oil/ rust or a moist electrode for stick welding is sure to cause problems. Always keep in mind that the 7018 electrodes which are used in stick welding needs to be kept dry and warm in an electrode oven. In case there is no oven, then all you need to do is heat the 7018 electrodes before using them for welding.

Mistake #4 – Not cleaning the metal correctly


This is one of the most common and perhaps easily avoidable mistakes in the welding process. The quality of welding is affected if the metal is not cleaned in the right manner. Especially in the case of TIG welding, it is crucial that you use the right solvent like acetone. This way the quality of the welding will not be compromised. Other solvents like paint thinners etc too can be used for cleaning the metal.
