Have you ever heard of a welding process called ‘hot work’? Welding has been used since the prehistoric era, and this particular process has become increasingly important in recent times.
According to statistics, hot work welding accounted for more than 40% of the welding done in the US in 201 Hot work welding is not just a simple welding task – it involves special techniques to ensure a smooth joining of two metal surfaces. In this article, you will learn the importance of and techniques involved in hot work welding.
So, keep reading and get ready to become a welding expert!
What is Hot Work in Welding?
Hot work in welding is a process that involves welding, cutting and other processes that involve burning or grinding.This type of welding typically requires an environment that is free of explosive gases, vapors and dust. Generally, there are two types of welding: hot work and cold work. Hot work is a welding process that uses heat generated by an electric arc or a combustible fuel-oxygen flame as the heat source.
Advantages of Hot Work in Welding
Hot work welding has several advantages over cold work welding:- Can be used to weld materials such as steel, aluminum, copper and nickel.
- Produces welds that are strong and long-lasting.
- Reduces the time, cost and resources needed to produce the weld.
- Hot work welds are less prone to cracks and other defects.
- Produces smoother welds that look better when finished.
Disadvantages of Hot Work in Welding
Hot work welding has some disadvantages as well:- Hot work welding must be done in an environment that is free of explosive gases, vapors and dust.
- High temperatures used during hot work welding can cause weld distortion.
- It is more difficult to achieve high-quality welds with hot work welding.
- Hot work welding may require preheating of the workpiece.
- It often requires specialized skills and equipment.
