- Earplugs or earmuffs to protect ears from loud noises
By wearing the appropriate safety gear, welders can ensure their safety and prevent potential injuries while performing MIG welding.
2. TIG Welding Techniques and Tools
TIG welding is a precise welding technique used in General Fabrication.
What is TIG welding?
Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW), is a type of arc welding process that uses a non-consumable tungsten electrode to produce an electric arc that melts the metal being welded, creating a strong bond between two metal pieces.
So, TIG welding is useful for producing high-quality, clean welds and is commonly used for thin metals, stainless steel, and aluminium.
Pros and Cons of Tig Welding
Here are some common pros and cons of TIG welding, but remember that these may vary depending on your specific applications and welding conditions.
Pros | Cons |
|---|---|
Produces high-quality, precise welds with minimal spatter or fumes Provides better heat control and can be used for thinner materials Welds can be made with or without filler metal, giving more control over the process Create a better visual appearance of the weld Low heat input reduces distortion | Slower welding speed compared to other processes Requires a high level of skill and control, making it more difficult to learn and master More expensive process compared to other welding methods Tungsten electrodes can be brittle and prone to breaking, requiring frequent replacement Not suitable for high-volume production due to slower speed and higher cost |
Tools Required for TIG Welding
TIG welding needs a few tools, including a TIG torch, tungsten electrode, and filler wire.
I. The TIG torch
This is used to direct the heat onto the metal pieces
II. The tungsten electrode
The tungsten electrode creates an arc that melts the metal
III. The filler wire is then added to join the two pieces of metal together
What is better, MIG or TIG?
We recommend that MIG welding is faster and more efficient for thicker metals, while TIG welding is better suited for thinner metals and produces higher-quality welds.
Overall, while both MIG and TIG welding can produce strong welds, TIG welding is often preferred for applications where high-strength and high-quality welds are required.
However, a better understanding of the differences between TIG and MIG welding can help determine when to use each technique.
Other Tools Needed for General Fabrication
Cutting and shaping tools are essential for General Fabrication.
Let us tell you the most important tools that you need to know for this purpose.
Cutting Tools
Two of the most commonly used cutting tools in this process are plasma cutters and oxy-acetylene torches.
- Plasma Cutters use a high-velocity jet of ionized gas to cut through metal quickly and cleanly
- Oxy-acetylene Torches use a flame fueled by oxygen and acetylene gas to melt and cut through metal.
Both of these cutting tools are essential for creating precise cuts in metal during general fabrication.
Bending and Shaping Tools
Brakes and rollers are two examples of tools used for bending and shaping metal.
- Brakes are used to bend sheet metal into different shapes and angles
- Rollers are used to shape metal into curves or cylindrical shapes.
These tools require skill and precision to use effectively, but they are crucial for creating custom metal parts and components.
Finishing Techniques Used to Prepare the Final Product for Use
1. Sandblasting
Sandblasting is a common finishing technique used in general fabrication to smooth rough edges and remove surface imperfections.
