What Makes a Good Weld?

To properly weld your first need to understand what a good weld as it’s a very important aspect of becoming a good welder. A brittle weld can cause weak joints becoming a major safety issue in construction or industrial settings. Regardless if your welding for a structure or just for a DIY project at home understanding what a good weld will help you become a successful welder.

Here are some key factors that will ensure a good weld.

Clean Surface

Before the fun begins prepping a metal surface and cleaning it from impurities such as water, oil, oxide and flux prior to welding is a very important aspect to ensure a strong weld. Without starting with a proper clean surface the impurities will cause a brittle and porous weld that can dramatically weaken the joint.

Welding the Gap

Another aspect that can cause a weak join is caused from improper gap or edge preparation between the two pieces of metal being welded. A gap that is two large between the two pieces of metal can cause issues as the weld bead might just burn away the edges. If the gap is insufficient when joining thick metal together it might cause a lack of weld penetration resulting in a weak joint. To ensure a good weld both edge preparation and weld gap should paid attention to before starting the weld.

Inspecting the weld

Once the weld has been made the most important step is to inspect the weld and make sure the bond is strong between the two pieces of metal.  The easiest way to check for defects is to simply just look at the weld and inspect it. In Industrial settings where a weld in considered to be structural sometimes other tests are required by using liquid penetration and X-ray inspections. No matter what type of inspection you use, ensuring that the weld is strong and defect free is a very important step. Having a smooth weld that is free of defects such as slag, cracks, porosity and lack on penetration is a good way to ensure proper bonding between the two metals.

Here is a great tutorial for MIG welding for beginners.
