It is essential to be aware of all of the things that welders need to do and not do when approaching a project. Even the most skilled welder can make the most common mistakes. Here are some common mistakes that are made and how you can avoid them.
Not Properly Preparing Your Project
Significant mechanical stressing can cause one of two different types of cracks: hot and cold. Hot cracks can occur when the metal has begun to solidify and has not cooled down enough to resume work. Cold typically happens after welding, whether it has been several hours or several days. To avoid these and other issues, make sure you are properly prepped. Make sure edges have been prepared and the bevel angles determined before beginning the project.
Commonly found in stainless steel projects, when the metal comes into contact with iron and a conductive medium, it will create galvanic corrosion. This will cause deterioration of the stainless steel’s passive layer and could cause pitting and other problems. To prevent, make sure any tools of clamps you use have not been used on carbon steel beforehand.
Not Taking Proper Safety Precautions
Safety is the #1 rule when welding metal. It is important to be hypervigilant on tool maintenance and use. Some of the danger is also injury to the welder that cannot be repaired, such as eyesight damage or loss, hearing loss, burns, and so much more. Ensure inspecting safety gear each time before use, and if there is any flaw (major or minor), replace the item to keep problems to a minimum.
Choosing the Wrong Gun Size
It is essential to use a low amperage gun for welding to avoid wasting time and money with having to purchase replacement equipment if the gun is too low or high. It will help decrease needed downtime and provide greater maneuverability. Additionally, it will increase the longevity of the gun.
