Welding Tips and Tricks to Take your Welding Skill Up to a Notch

Are you looking for some effective welding tips and trick that you can implement right away? Then you are one the right page. In this very article, I am going to show some advanced tips and tricks that will help you to level up a bit of your skill.

Having that said, if any of you are expecting to learn to weld from this guide, then hit the back button right now because this is not the guide you are looking for. So let’s not waste and get started!

Step By step tricks

1.

Welding thick steel


Most welders don’t know that adjusting the amps, wire speed and volts on a wire welder can make transfer modes fine-tuned to thick metal. Globular and spray mode of the machine is for welding on thick material. The only limitation of these two modes is, they can only weld on metal that is 1/8-inch thicker.


When the voltage, feed speed, and the amp is set higher than the standard short circuit mode, that can produce large globes of expelled wire. And this mode delivers great deep penetration on thicker materials. That being said, they produce a lot of spatter as well.


And when the amps, wire-speed, volts are higher than the globular model that results in a stream of small molten droplets which sprays over the arc from the wire to metal. However, in order to get the genuine spray, you will need to use argon rich gas. With the spray arc, you can get good looking weld beads. That being said, spray arc can be used for only flat and horizontal fillet welding.

2.

Cleaning off impurities 


According to studies, a lot of newcomer welders forget to prepare the metal properly before welding which results in a bad weld. Preparing the metal means, removing dust, rusts, dirt and other contaminants that the metal consists. Before welding cleaning, the metal is highly important since the quality of the weld widely depends on that. In order to clean the metal entirely and effectively, you might use a grinder or wire brush.


Another reason for cleaning the metal is Hydrogen. It is a big enemy of welding, it can destroy even the finest welds easily. And hydrogen is available everywhere, it is on the rust, dirt, water, grease, manure, paints, etc. So what can you do to get rid of it? More brutal cleaning. Using a top-notch grinder for cleaning metal can solve the issue completely.

3.

Controlling the angle, direction, and speed


Angle, direction, and speed control is a highly important skill to develop, welder that have good knowledge about these, they will be able to produce a great weld.


When welding if it produces slag then you have to drag the rod. Let’s make it more simple, just remember when you are welding with flux-core wire or a stick welder, you would want to drag the wire or the rod. And when you are using MIG welder, then you have to push the wire forward.


When you are doing wire welding hold the gun at 10 degrees to 15-degree angle towards the direction you will be pushing. And when stick welding you have to maintain a 20-degree to 30-degree angle towards the direction you will be dragging the wire. And hold the wire or rod at 45-degree angle when you are doing fillet weld.


Arc spacing: Being able to adjust the travel speed is another thing that contributes to good weld. Plus adjusting the speed is important so that the arc remains within the leading weld pool. You have to keep a work distance of 3/8 - ½ inches and for stick welding, the distance should 1/8-inches between the workpiece and the rod tip.

4.

Gas selection


When MIG welding being able to choose the right gas is a great skill since the quality of the MIG weld depends on the gas. However, let me give you a little idea about different gases.


  • If you want to produce great-looking welds and want to weld at higher amp than you are going to require 75-percent argon and 25-percent CO2. That being said, Co2 can create a lot of spatter.
  • For welding on a rusty metal or heavy plate steel, you are going to need 85-percent argon and 15-percent CO2. And you will get spatter.
  • When doing spray transfer welding on the heavy or thicker metal you will need 90-percent argon and 10-percent Co2.
  • You will need pure 100-percent argon for welding on a sheet of aluminum. A mixture of argon and helium will also work.
  • And in order to weld in stainless steel, you are going to need 90-percent argon, 7.5-percent Helium, and 2.5-percent CO2.
5.

Welding aluminum


Welding aluminum requires good welding skill and some equipment as well. However, there is a misconception that is wire welder cannot weld aluminum. You can weld aluminum with any wire welder and the process is easy as well. But there are a few things that you might need to add to your inventory.


You would need to purchase U-groove drive rolls which will support the wire and won’t crush it down. And you have to keep the adjustment of the drive-roll at the loose side. You will also need to replace the cable liner by Nylon. Teflon, or other similar products.


And always remember when welding aluminum, you are going to need 100-percent pure argon gas, a mixture of argon and helium will work as well. Choose a 3/16 or 1/6 diameter aluminum filler wire and the reason is they are easy to feed through the gun cable.


Before you weld the aluminum you want to clean off all kind of grease, manure, oil, etc. with mild alkaline solutions like string soap or degreaser. Do not use strong alkaline or acidic cleaners. That’s the preparation you have to take before welding, once you have cleaned the aluminum you are all set to weld.
