Welding is an art that has been around for centuries. It's been used for many different functions and purposes, from being a skill to being a vital part in the construction of buildings, jewelry-making, décor pieces, and more. Welding is gaining more popularity as a trade. The skills learned from welding are so diverse that they can expand the way a person thinks and uses imagination. Whether a career welder or a hobbyist, the skill of welding can be used in infinite opportunities. A person can improvise current job skills and trade, create art for homes, learn new skills, or simply have fun creating quality projects in spare time.

In this article, we will discuss what gas welding is, its many types, and the best picks for a gas welding machine. For someone who is looking to buy a welding machine, this article may help you with the correct information.

What is Gas Welding?

Gas welding is done by using a gas flame to melt the sides or surfaces so that they join, allowing the molten metal to flow together, forming a solid continuous joint upon trying to cool.

This method is ideal for joining metal sheets and plates with thicknesses ranging from 20 to 50 mm. As a welding rod, a filler material thicker than 15 mm is added to the weld.

With a good-quality gas welding machine, one can achieve finer results out of this activity.

Let’s jump on next to understand the different types of gas welding.

Types of Gas Welding

1. Oxy-acetylene Welding

The welding torches in oxy-acetylene type of welding are supplied with a mixture of acetylene and oxygen gas. The most commonly used type of gas welding is oxy-acetylene welding. The flame temperature of this gas mixture is the highest among available fuel gasses.

Although, of all the fuel gasses, acetylene is the most expensive. Because acetylene is a volatile gas, it must be handled and stored with caution.

2. Oxy-gasoline Welding

When construction costs are a concern, pressurized gasoline is used as a welding fuel, especially in areas where acetylene canisters are not readily available. For torch-cutting thick steel plates, gasoline torches may be more effective than acetylene torches.

Gasoline can be manually pumped from a pressure cylinder, which is a standard procedure among jewelry makers in impoverished areas.

3. MAPP Gas Welding

Methylacetylene-propadiene-petroleum gas welding is the term used here. The (MAPP) is a gas mixture that is far more insoluble than other gasses, making it safe for trainees and leisure welders to use and store.

MAPP is used in high-volume cutting operations and can withstand extremely high pressures.

4. Butane or Propane Welding

These are nearly identical gasses that can be used separately or in combination as fuel gasses. When compared to acetylene, butane and propane have relatively low flame temperatures but are less expensive and easy to handle.

Soldering, bending, and heating are all done with propane torches. Because propane is a heavy gas, it calls for a different torch tip than an injector tip.

5. Hydrogen Welding

As hydrogen can be used at higher pressures than other fuel gasses, it is especially useful for underwater welding.

Electrolysis is used in some hydrogen welding equipment to split water into hydrogen and oxygen, which is then used in the welding process. Small torches, which are used in the fine jewelry making processes, are frequently subjected to this type of electrolysis.

Which Gas Welding Machine Should You Buy?

To buy a welding machine, one must think of various factors including the durability, weight, tools required, the type of gas welding machine, the brand, etc. There are many good welding machines and their parts available in the market ranging from Rs 1,300 to as high as Rs 1,72,637. If you’re looking for an inverter arc gas welding machine, then go for the iBell welding machine, starting from Rs 5,000. The most basic iBell welding machine comes with a multipurpose control panel and is easy to carry with a versatile design. Its lightweight and compact body offers overheat protection.
