There can be many problems that occur during MIG welding in general. One of the biggest problems can be porosity. Porosity happens when the gas is trapped in the weld metal that creates cavities in the metal, causing its quality to degrade.
This problem usually happens because of inadequate shielding gas, which gets trapped and freezes inside the metal.
Another big problem regarding MIG welding is improper bead profile in which a convex-shaped bead is formed, indicating that there is insufficient heat provided for the penetration into the base metal.
With better remedies, these problems can be fixed and overcome.
How do you Reduce Spatter in MIG Welding?
Consistency and steady hands are the keys to reducing spatter in MIG welding. Consistency during wire speed can reduce spatter by tenfold. The more consistent you get during wire speed, the more minor spatter you will see.
So that means all you need is experience and a good welding grip, which usually comes with time. But there can be other reasons for the cause of spatter. Sometimes a specific metal is not applicable for welding, which causes spatter. Such metals have non-weld-able components that make welding hard. So by simply switching to a weld-able metal, you can reduce spatter without having to go through the trouble of welding metals that are never meant to be welded
Cleaning MIG welding
MIG welding is a lot easier to learn as compared to other welding methods. However, knowing the fundamentals of welding still takes a bit of time.
But even if you are a beginner or a semi-pro. MIG welding can be done by those who have little or no experience in it. Compared to many other types, such as TIG and flux-cored arc, MIG is comparatively easier. It is simpler to use and get the hang of.
