Learning how to weld? Study these welding tips for beginners and experts to create the best welds!
Spend some time to prepare
Just as you need to prepare yourself for a theater play, you also have to prepare before you stick weld. Stick welding could be the most forgiving welding process out there when dealing with rusty or dirty metal, but it doesn’t mean you won’t prepare the material the right way. And when I say prepare, I mean cleaning the material. Use a grinder or a wire brush to get rid of the grime, dirt, or rust from the metal you wish to weld. Otherwise, you’ll increase the chances of coming up with a bad weld. Unclean conditions could also lead to porosity, inclusions, cracking, and lack of fusion. So, make sure you prepare everything—the material, the spot, and the clamp to be used. Remember, you’d want to have a stable and good electrical connection to maintain the arc quality.
Position yourself correctly
It’s not enough to clean everything; you should also know how to position yourself to have the best view of the weld puddle. Think of it as placing yourself on stage like an actor. You shouldn’t block the audience’s view with your back. It’s similar to welding. Make sure you keep your head off to the side and away from the smoke. This way, you can see the joint you’re welding as you keep the arc on the leading edge of the puddle. Also, be sure your stance will enable you to support and control the electrode comfortably.
To produce beveled edges on thick materials that are more than 3/16″, use a grinder or a plasma cutter. However, you can settle with a square groove weld for thin metals.
Follow the right angle
Whether it’s a square groove weld or a v-groove weld you’re doing, ensure that the electrode is kept at the right angle to the metal, but do lean it in the direction that you are welding. Tilting it in another direction will make your welds ineffective, and the whole welding activity would be dangerous.
Have grace under pressure
When you start your arc, don’t worry if your electrode gets stuck to the metal. Just slightly twist the electrode. Doing so will loosen it, enabling you to attempt again.
Move the electrode smoothly and steadily
Do this so that the arc won’t break. Moving the electrode too distant from the metal isn’t a good idea. To correct this, start over and make sure that you keep the same distance away from the joint. Work out the most suitable arc length. Read the manufacturer’s guidelines and specifications. In general, however, electrodes with a diameter of 1/8″ or more require an arc length of 1/8″. For smaller electrodes, an arc length of 1/16″ is more appropriate.
Apply the right speed
Your travel speed can also affect the penetration. If you move the electrode too slowly, your weld pool will build up, and you’ll end up with excessive weld deposit. If you move too fast, your welds will be inconsistent and narrow. The key is to find the right speed, which you can figure out if you take some time to practice.
Stick welding isn’t actually that complicated. It’s a simple welding process as long as you know these crucial tips. And now that you do, you can now apply them the next time you weld!
