MIG Welding Technique for Vertical Gaps

MIG welding is a process that needs you to have a clear concept and knowledge of how the process works. It is important irrespective of the type of welding you need to perform with a MIG welder. Metal Inert Gas Welding Process commonly termed as MIG enables you to repair and make various components. The processes are certified and are accepted to be ideal for performing varied welds.

In this article, we will share some basic details related to MIG welding technique for vertical gaps. All those who want to improve their welds can read through and get useful help from this article. This process of MIG welding has risk potentials of causing hazards and thus with proper care and technique one can safeguard himself. Plasmacutteradvisor blog is expert on welding.

Important: No matter which MIG welding technique you are relating to in a process, it is important to ensure that all the safety related information is carefully read and followed before beginning your welding task. Safety instructions must always be read before using any power tool and these details you can find in the user manual of your tool.

Vertical MIG Welding:

Usually, most of the projects that require welding are flat horizontals. However, this may not be the case at all times. There will be times when you will need to deal with varied shapes and sizes. In some cases of welding such as field welding, you may need to deal with some large sized items that would need you to work through vertical welds.

This technique of vertical welding is something difficult in comparison to flat welding and there are certain differences in the process. We will now be sharing some important tips and tricks that would make your job easier. Any welder who is performing MIG welding process must also master

This technique of vertical welding is something difficult in comparison to flat welding and there are certain differences in the process. We will now share some important tips and tricks that would make your job easier.

Any welder who is performing MIG welding process must also master a technique for filling in vertical gaps with the use of a MIG welding gun.

Different Vertical MIG Welding Techniques:

A welder can perform either uphill vertical welds or downhill vertical welds. Which direction you choose usually depends on your personal preference along with on the selection of wiring you will be using. You can use a solid wire or a flux core.

Using Solid Core Wire:

Usually, welders find working with solid core wire much easier when they are working their way for downhill welds. In order to get desired results, you should have your MIG welding gun faced between 5 to 15 degrees during the process.

In order to prevent build up of excess metal and from falling it away from the joint of the weld, it is necessary to have it stay ahead of the puddle.

Using Flux Core Wire:

If you use flux core wire, best results can be achieved by performing uphill in order to prevent contamination of welding. For this process, you should have your MIG gun pointed up and should be held at an angle anywhere between 5 to 15 degrees going your way up.

Important Information Related to Processes of Vertical Gaps Welding:

Vertical MIG welding whether going uphill or downhill is a daunting task. In order to produce quality welds, you should know the setup and technique before welding.

In the process of vertical welding you will work against the force of gravity and thus you should have the voltage of your tool reduced along with a 10 to 15% reduction in amperage in comparison to what figures you were using with horizontal or flat welding. Vertical position welding is similar to fillet weld however in this case the filler metal is dropped on one side and another bead from

Vertical position welding is similar to fillet weld however in this case the filler metal is dropped on one side and another bead from the bottom of the other side to the top. Alternative sides are filled until the hole is complete.

A welder must also know how to get best results in any situation whether he should go vertical down or vertical up for welding.

If you are not careful then you may get rough surface. You need a best planers to make the rough welding to normal look. So careful while trying for vertical welding.

Vertical down Welding:

A vertical down welding technique would begin from the top of the joint and welder would need to proceed down. Usually, this process proves best when you need to deal with thin metals. The reason behind it is that as you move down, you get the faster speed of travel and thus the arc penetrates less. This process would prevent

This process would prevent excess melting of material and thus you will be able to easily deal with thin metals while working in this position. Another point of concern when dealing with thin metals is burn-through.

To tackle that you need to angle your gun slightly up and then pull it downwards. The electrode wire must be kept on the puddle leading edge. A slight interlace would aid in flattening the welding crown.

Vertical up Welding:

A vertical up technique would begin from the bottom of the joint and welder would work its way upward. This technique works well for dealing with thicker metals, for instance, something with 1/4 inches or more width.

A welder can easily control shaping, size and temperature of the puddle with a very slight weave.

Conclusion

In order to make a nice weld, you may need to work your way with a combination of different techniques of welding. It is only with practice, you will be able to master at all the techniques of welding using MIG welder.

A good vertical MIG welding technique would enable you to fight against gravity as it pulls downward. Vertical welding if properly adopted is one of the most effective ways of doing lap and tee welds.

So practice more and master yourself at this technique in order to be an all-rounder welder for all different positions of welding.
