What is the meaning of backhand welding?

The backhand method means the torch is positioned so that the wire is feeding opposite to the direction of arc travel. Filler metal is being fed into the weld metal previously deposited. For the forehand method, the torch is angled so that the electrode wire is fed in the same direction as arc travel.

What is forward and backward welding?

In forward welding, the flame or electrode is pointed towards the direction of weld progression. In backwards welding, the flame or electrode is pointed away from the direction of weld progression. Here the torch is inclined at an obtuse angle (usually 135° – 150°) with the feed vector.

What is an advantage of backhand or pull welding?

When you are backhand or pull welding the torch comes before the rod. You’ll find that this method of welding does not require as much sliding, or transverse motion, compared to the push welding technique. Backhand welding also produces less puddle and you will therefore use less rod in comparison to forehand welding.

What are the three welding techniques?

Three of the most common are Arc, MIG (Metal, Inert Gas) or GMAW (Gas, Metal Arc Welding), and TIG (Tungsten Inert Gas) welding. In order to know which process is best for the particular job you’re working on, here’s what you should know about each of them. Arc welding is the oldest of these three welding processes.

What is forehand welding?

Forehand welding is a welding technique that’s characterized by the application of the rod before the torch. With forehand welding, the worker holds the torch at roughly a 30-degree angle from his or her right side. This allows the torch to point directly between the rod and welding puddle.

Which welding technique is known as forward welding technique?

Leftward or Forward Welding: In this technique, the torch is held in the right hand and the filler rod is in the left hand of the operator. The welding is started from the right hand end of the plate and travels towards left hand.

What is forward welding?

What are welding techniques?

There are four main types of arc welding processes. These are termed Stick Welding (SMAW), MIG Welding GMAW, TIG Welding GTAW and Flux Cored Arc Welding FCAW. In this post, we will be taking a closer look at these four processes.

Which technique is used in welding?

Gas welding is a process in which two or more parts of the metal are mixed or united using heat transmitted by the heat produced by the reaction of oxygen and fuel gas. Gas welding is also called oxy-fuel welding. This is called oxy-fuel welding because oxygen is used along with the burning fuel in this process.

Why is the forehand welding technique preferred for welding thin materials?

What is this? In general, the forehand method is recommended for welding material up to 1/8 in. (3.2 mm) thick, because it provides better control of the small weld puddle, resulting in a smoother weld at both top and bottom. The puddle of molten metal is small and easily controlled.

What is forehand and backhand welding?

To understand forehand and backhand welding you must for understand the basics of your Work angle. The work angle is basically the angle of your electrode or welding torch in relationship to the surface of the metal (the base metal as it’s referred to) you are welding.

What is the backhand angle in welding?

Backhand welding is also referred to as pull welding. It’s also the drag angle. Put simply the angle of drag is where your welding rod is pointing in the opposite direction are welding but the torch is at about a 30 degree angle give or toward the direction you are welding.

What are the advantages of backhand welding?

Because of the position of the torch and filler rod, the worker is able to create an even and consistent arc. In turn, this allows the worker to evenly distribute the filler metal. Backhand welding also creates less splatter than forehand welding, making it desirable among workers.

What is the difference between forward welding and backwards welding?

In forward welding, the flame or electrode is pointed towards the direction of weld progression. In backwards welding, the flame or electrode is pointed away from the direction of weld progression. Here the torch is inclined at an obtuse angle (usually 135° – 150°) with the feed vector.
