What Should a Beginner Welder Know

If you’re thinking of picking up welding as a hobby, there are some things you should know before you start. Welding can be a fun and challenging way to express yourself creatively, but it’s also a skill that takes time and practice to master. In this blog post, we’ll go over the basics of welding and what you need to get started. So if you’re ready to learn, read on.

What Should a Beginner Welder Know: Main Points

Check the Equipment

Make sure the welding equipment you are using is in good working order before you begin the project. Assuring proper connections are made between the welding gun, the gas tube, and the power cable is important. The type and diameter of your filler material must also be correct, as well as your shielding gas.

Detach your welding gun from the wire feeder and check if the size and type of the liner of your gun are appropriate for the filler material and wire diameter you use. Make sure the gas nozzle is clean of any welding splashes.

Check the Welding Torch Speed

Welding success depends on the speed of the welding torch. Weld shape, heat input, and penetration are all affected by speed. Weld penetration may be very small if the speed is too high. Alternatively, a slow speed may result in the too much-molten weld pool.

In order to determine the speed in centimeters per minute, weld approximately 10 cm and time it with a stopwatch.

Adjust the Welding Parameters

Welding current and wire feed speed go hand in hand since the welding current follows the wire feed speed. For proper welding, ensure that the arc voltage is correct based on the wire feed speed and welding current.

Check if the arc voltage is too low compared to the welding current and wire feed speed by checking the following:

• There is a lot of spatters when welding.

• The arc produces a loud sound.

The following factors can indicate that the arc voltage is high in relation to the wire feed speed and welding current:

• The arc produces a soft sound.

• The weld pool is wider.

• The arc is long.

• The volume of the filler material is large.

By increasing or decreasing the wire feed speed, you can adjust the arc voltage to a workable figure. In some welding machines, however, the welding current and wire feed speed are used to determine the correct arc voltage.

Use Hot Start and Soft Start Features

In a hot start metal arc welder, a large current is generated when the arc is struck. As a result of this feature, metals are easily fused at the start of welding, allowing it to go smoothly from there. Aluminum, for example, generates faults easily at the beginning of welding, but the hot start can reduce them when welding materials with good thermal conductivity.

When hitting the arc, the soft start feature gives off a low current. Soft starts help keep steel sheets’ edges intact when welding; you can adjust both the power and duration of both features at the control panel.

Other Welding Tips For Beginners:

• Prepare Your Welding Materials: Before welding, clean your metal surface using a wire brush or sandpaper, then apply a coat of primer to protect it from corrosion.

Wear Correct Welding Gear: You need to protect your skin and clothes from the sparks and flame during the welding process. Therefore, you need to wear a welding helmet, boots, gloves, and sleeves. As earlier mentioned, each protective gear protects specific parts of your body.

• Maintain a good working position: The best position to do welding is downhand, which involves placing the working materials on a level to ensure you can do your welding in a natural position.

Use Dry Welding Rods: Avoid using damp rods since they cause the arc to be rough. Always store your welding rods in a sealed container when not in use.

• Use the Correct Type of Tungsten: Different types of metals work with different types of tungsten. For example, aluminum works well with green tungsten, while steel metals work well with red tungsten.

• Be Careful When Working With Stainless Steel: Overheating stainless steel can make the material lose its shape. To determine how much heat to apply, observe the color of the weld. The heat applied should be sufficient if the weld color is golden. 

It is a sign of excessive heat if the color of the weld is dark to dirty gray. This kind of problem can be prevented by reducing the amps and increasing the travel speed.

Do Not Melt the Filler Rod Directly: The weld will be weak if you melt your material directly.

Relax Your Hand: Do not hold the gun too tightly. Relax your wrist to control the weld pool and have a good weld.

• Have a Welding Mentor: In addition to training and practice, having an experienced welder by your side will enhance your learning experience as you will get good advice that will get you to the next welding level.
