Types of welding joints & Current setting

 Welding Joint 

1. TEE Welding joint.
2. EDGE Welding joint.
3. CORNER Welding joint.
4. BUTT  Welding joint.
5. LAP Welding joint.

Now that you have a better understanding of some basic welding techniques and the process behind them, here are some quick tips we would recommend to any beginner welder:

• Understanding AC and DC currents. Learning what current to use for your job is a necessary step in getting a strong weld. Depending on the job and the tools you use this can vary.

• Clean the material before starting. A good scrub with a wire brush, grinder, or sandpaper will remove a majority of the dirt and rust from the material, this helps to get a stronger weld and better porosity.

• Remember to put your helmet down. Even some of the most experienced welders are known to forget this step, most of the time because their hands are preoccupied or they simply forget in the process of things. Remember that you can’t weld without working eyes!

• Tacking is a necessary step as it ensures the material is secure and in place before welding. Tack welding is putting short, set-up welds that hold the edges together and are easily correctable if a part needs to be dissembled and re-secured before welding.

Some basic and useful welds that are great for beginners to practice are:

• A grinder will soon become your best friend. It’s safe to say if you’re new to welding your first one, two, or 30 attempts at welding something specific won’t turn out as planned. But never fear! a grinder can cut that bad boy back like nothing ever happened. Patience helps too.
• Blueprints. If not taking a specialized course, taking the time to understand blueprints can go a long way in helping you understand the reason and uses for welds in practical applications.
• Popcorn or Bacon? Many might tell you if your welding sounds like popcorn popping in a microwave your settings are either too hot or too weak for the job. Teachers often say to listen for that sweet sound, similar to bacon frying in a pan, to know if your weld is in a good setting.

• Have your head to the side, away from the smoke, is also best practice so you have a full view of the joint as you weld.

Miller Electric offers a great read on improving the Stick welding technique through their CLAMS guide, which provides all the informative and necessary steps to consider when beginning stick welding.

These points being:

Current setting

1. Length of arc
2. Angle of electrode
3. Manipulation of the electrode
4. Speed of travel

What is more, an understanding of the settings for Stick, MIG, and TIG welding can help you in grasping the concepts behind various other techniques of welding.

Understanding the Process

Basic welding is more than just melting two pieces of metal together, first, you must consider the type of welding machine you will use and what job you’ll be using it for. Now there are a variety of different methods of Arc welding, although the most common processes are Metal Inert Gas (MIG) welding, Tungsten Insert Gas (TIG) welding, and Stick welding.
