Jen reportedly said afterwards that she studied welding for two months before filming began, but because the director wanted more sparks on camera, she was forced to do a terrible job. Perhaps we can let her off the hook. It is used to join pieces of metal together and is a very skilled trade. So what are the different types of welding and what are they used for in industry?

MIG welding is actually two different types of welding. The first uses bare wire and the second flux core.

Bare wire MIG welding can be used to join thin pieces of metal together. Flux core MIG welding can be used outdoors because it does not require a flow meter or gas supply.

Stick Welding Stick welding, also known as Arc welding, is doing it the old fashioned way. Stick welding is a bit harder to master than MIG welding, but you can pick up a stick welding equipment for very little if you want to have a go at home.

Stick welding uses a stick electrode welding rod. It occurs within the metal, and you can find it with internal detecting machines only.

Fixing Problems Related to Weld Porosity

Here are a few of the most common causes of weld porosity and solutions you can use to limit porosity in your welds. Cause: Impurities on the surface of your metal.

Solution: Clean your metal thoroughly before you weld it. Cause: Excess shielding gas.

Solution: Use the correct amount of shielding gas. You can usually find that information in the instruction manual for your welding machine or in the literature that comes with your electrodes or electrode wire.

Cause: Damp electrodes. Solution: Store your electrodes in a clean, dry place.

The most common is slag, a non-metallic solid material trapped in the weld or between the weld and the base metal. One of the most common causes of slag inclusions is the presence of coatings on certain metals.

Aluminum, for example, is often coated in aluminum oxide, which forms rapidly when aluminum is exposed to air. The same goes for other coatings on other metals.

Copper backing bars are another common source of slag inclusions. The copper can melt away and become trapped in the finished weld. Preventing Incomplete Fusion between the Weld and Parent Metals Incomplete fusion is a lack of penetration or fusion between the weld metal and the parent metal of the piece.

Welds with incomplete fusion are weak and substandard welds at best if not downright dangerous. Here are a few of the most common causes for incomplete fusion, and solutions that will help you avoid the problem.
