MIG Welding Tips and Techniques for Beginners | Welding Page



How to Weld - MIG Welding : 11 Steps

Putting to practice any of those tips is probably going to enhance the standard and sturdiness of your weld.



  • CLEAN, CLEAN, CLEAN


The number one failure of a MIG welder is porosity. the foremost common explanation for porosity is welding a unclean , oily, painted surface. of these contaminants get trapped within the weld, leading to holes that resemble a sponge. “Farmers too often fail to adequately prepare the metal before welding,” says Welding Page’s John Leisner. “This includes grinding or removing paint, rust, dirt, and other surface contaminants and also fully grinding out cracks, oftentimes beyond what's immediately visible.”


  • GET an excellent GROUND


Collier considers this the foremost common failure with MIG welding. “Your welder doesn’t care if you've got a nasty ground. It just keeps pumping out welding wire anyway regardless of if your gun is sputtering and stuttering,” he explains.

Lincoln Electric’s Karl Hoes says a welding arc requires a smooth flow of electricity through an entire circuit . Welding current will seek the trail of least effort . So if care isn't taken to put the welding ground on the brink of the arc, the present may find another pathway. Firmly attach the clamp to reveal metal as close as possible to the arc.

  • KEEP YOUR STICKOUT SHORT

As a general rule, keep the space the wire stands proud from the top of the gun’s contact tip to between 1/4 and 3∕8 inch. “This simple tip can have the most important effect on your MIG welding,” says Jody Collier.


  • USE BOTH HANDS


“Use both hands whenever possible,” Collier urges. “Rest the crook of the gun neck in one hand and hold the spare the trigger within the other hand. Don’t hesitate when it involves having your prop hand on the brink of the weld. Get a heat-resistant, heavy welding glove if you would like it.”


  • hear YOUR WELDER


Music to your ears should be a gentle buzz while welding. a gentle hiss can indicate your voltage setting is just too high, notes Leisner. “A loud, raspy sound could indicate the voltage is just too low. A crackling sound sort of a machine gun going off indicates too high an amperage setting,” he adds.

  • KEEP THE ARC UP FRONT

“For better penetration, keep the arc at the vanguard of the weld puddle,” says Collier.

The exception to the present rule would be when welding thin sheet . during this case, keep the arc back farther within the puddle to stop burn-through.

  • MATCH DRIVE ROLLS | GUN CABLE LINER | CONTACT TIP TO THE WIRE SIZE

Surprisingly, this basic matching up is usually ignored. If you're trying to run .030- diameter wire through .035 rolls, you'll end up constantly changing feed speed and never getting that setting right, because the grooves on the rolls are overlarge . an equivalent advice applies to the gun cable liner and get in touch with tip size.


  • PUSH OR PULL


The most common method is to push the gun toward the direction of the welding page. Forehand welding produces shallow penetration with a flat, wide, smooth surface with you mig welding.

The second approach comes once you drag the gun (the backhand method). This produces a deep penetration weld that's narrow and high within the center.

So what method do you have to use? That depends on the thickness of the metal you're welding and the way deeply you would like to penetrate the weld.

  • WATCH WHEN WELDING OUT OF POSITION

If you're welding vertically, horizontally, or overhead, “keep the weld pool small for best weld bead control, and use the littlest wire diameter size you'll ,” says Leisner.


  • REPLACE CONTACT TIPS LIBERALLY


“Contact tips are cheap,” says Collier. “Keep a pack in your toolbox and replace them often.” Worn contact tips are typically oval and cause an erratic ARC. Also, if a tip enters the molten weld pool, it should be immediately replaced. for many casual welders, an honest rule of thumb to assure high-quality welding is to vary the tip after consuming 100 pounds of wire.


  • READ YOUR BEAD


You can learn tons by watching your finished welding bead, says Eisner.

A convex-shape or ropy bead often indicates that your setting is just too cold for the thickness of the repair and there isn’t enough heat being produced to penetrate the bottom metal. A concave-shape bead indicates a drag with heat input.

Thanks to the internet, that we all can get a detailed information on almost everything. Below we gathered all of the important information you need to know before purchasing a welder best for you home use. Keep in mind, the best home welder is the one that works well for any job at hand.

Picking a welding machine for home use is pretty straight forward, once you know what you actually need to look for. You should always be able to narrow down what MIG welder for home or other types will work well and choose the one from the list of these best MIG welding machines. We have already researched and only compiled the ones which are good as a home use or hobby welder.

In case, you are a professional welder or just someone with a deep interest in heating metals, you will find value and quality in using a MIG (Metal Inert Gas) welder. Such kind of machine provides a range of uses which even beginners can immediately perform. Obviously, they are not particularly cheap, purchasing one is an investment. Thus, it is important for you and your pocket to pick the right model with affordable price. With Welding Page at the end, you will most probably find the best MIG welder for your home use for welder, hobby or profession. But first, let’s have a look at the top three products.

  • Getting started


Unfortunately, there is no single welding process suitable for all applications, so let’s begin with an overview of the basic processes and highlight the capabilities and advantages of each. This will help match a process to your specific needs.

If you have previous welding experience, feel free to skip ahead with welding page. If you’re a beginner, this section will give you a better understanding of the types of welders available, how each performs and the degree of welding skill required to operate each. In addition, you’ll find examples of right applications best suited for each process.

Matching your needs and welding skills with a process is critical before moving on to discuss specific welder model options on welder page.

  • Overview of welding processes

The most common welding page are MIG, TIG and stick. Each process has its own benefits and limitations and is better suited to certain applications. There’s no “one size fits all” approach.

MIG Welding — MIG welder use a wire welding electrode on a spool that is fed automatically at a constant pre-selected speed. The Weding Page, created by an electrical current between the base metal and the wire, melts the wire and joins it with the base, producing a high-strength weld with great appearance and little need for cleaning. MIG welding is clean, easy and can be used on thin or thicker plate metal.

Similar to MIG welding, flux-cored arc welding (FCAW)* is a wire-feed process but differs in that self-shielded flux-cored welding page does not require a shielding gas. Instead, flux-cored wire is used to shield the arc from contamination. This is a simple by welding page, efficient and effective welding approach, especially when welding outdoors, in windy conditions or on dirty materials. The process is welding page used in construction because of its high welding speed and portability.

Easiest process to seek out out
High welding speeds possible
Better control on thinner metals
Cleaner welds possible with no slag to scrub
Same equipment are often used for Flux-Cored Welding


  • TIG Welding

The Basics - Welding for Beginners | Best Welder for Beginners

The Basics - Welding for Beginners


Welder are everywhere, and they are doing amazing things. From diving a few hundred feet underwater to repair a few holes sprung in a steel ship out at sea to out in the cold vacuum of space, welding on a spacecraft that requires repair…Or even (and just as practical) you might just find an old bloke that simply wants to weld together a nice new steel table for his workshop.

Whatever the case, if you’re interested in taking up welding yourself, enrolling in specialised training to suit your goals is always the best way to learn. If you’re a DIY type of person and enjoy a little trial and error, this article can serve to help you understand some of the basic process and rules when it comes to beginner welding techniques.

  • Safety

First off, like with any work in the machine or steel working industry, a conversation on safety is necessary. For beginners, understanding the dangers and safety precautions necessary in the workplace is a fundamental step in becoming a great welder.

For the sake of avoiding this article becoming a guide on workplace safety itself, we highly recommend reading Safe Work Australia’s Model Code of Practice on Welding Processes. This outlines everything you need to know about safety standards, discussing all topics from identifying possible hazards to proper ventilation and protective equipment.

  • 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. The most basic form Adam Byron for welder and a great start for beginners, is Arc welding.

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.




  • MIG WELDING


MIG Welding is regarded as the easiest type of welding to learn, it works by using a wired welding electrode on a spool that is automatically fed through at a constant speed as you work. The arc melts the wire and joins it together at the base, resulting in a strong and clean weld.

The reason why gas is used in this welding technique, is because it provides a shield of fog that surrounds the puddle of hot liquid metal created when welding at intense temperatures. This gas shield keeps the weld puddle free of any contaminants and is what helps ensure a strong weld with low porosity (the empty spaces in a material). This process is useful in welding a variety of materials such as mild steel, stainless steel and aluminum welding Tips for New Welder.

A clear downfall of this method though, is using a gas requires an environment usually indoors and away from any wind or elements that might blow the gas away. This can be remedied with gas-less MIG welding, which uses flux-core wire. Flux-core wire is similarly fed through automatically and is made with a coating that creates the gas while you weld- This option provides a messier finish, with welds requiring more clean-up, and flux-core wire can be pricey.


  • TIG WELDING


TIG welding, on the other hand, is harder to learn and takes some practice before you can master it.

TIG welding is more physically complicated, as it requires a large welding rod to be fed manually into the weld puddle, and also uses a protective gas to protect the weld puddle. When TIG welding, you need to simultaneously: control the torch, feed the wire, move at correct speed and also use the correct current. This is usually used for thinner gauged metals and can be applied when working on toolboxes or kitchen sinks for example.


  • STICK WELDING


Similar to TIG, Stick welding involves using a fixed length electrode in joining metals, being a fixed length, the electrode is manually fed by the welder. Most DIY welder go to Stick welding as a basis for learning how to start weld journey.

This welding technique is one of the most versatile, inexpensive and forgiving processes of the craft. It can be done in just about any setting and is a good choice if a basic joint or attachment is required.

A downside to stick welding though, is that it often provides a messy finish and would not be a viable option where a smooth, clean finish is desired (such as in sheet metal working for automobiles).



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

These points being:


  1. Current setting
  2. Length of arc
  3. Angle of electrode
  4. Manipulation of the electrode
  5. 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.


This article only scratches the surface on the craft and if you will leave with only one piece of information before starting, let it be that safety is always first!
