Essential Welding Tips and Tricks for Professionals of All Ages

Whether you’re a seasoned professional, just getting into the welding profession or a passionate welding DIYer and hobbyist, it can’t hurt to brush up on some tips. Detailed below are tips for a couple of different welding methods, in addition to some general safety tips and reminders to ensure that your welding minimizes harm to yourself, others around you and your work setting.

Metal Inert Gas (MIG) Welding

Also known as gas metal arc welding (GMAW) or metal active gas (MAG) welding, MIG welding relies on the continuous feeding of a spool of hot metal wire to melt two components of metal together. MIG welding is typically quicker and easier to do than TIG welding, which we’ll get to in a moment.

Make Sure Your Wire Is Feeding Properly

Choosing the correct drive roll is crucial to your wire’s continuous feed during the course of the MIG welding process. Not enough tension can result in a poor feed. Bends in the wire can also lead to lost tension, so be sure to keep the gun as straight as you possibly can.

Know the Correct Specs for the Job and Your Equipment

This includes knowing which kind of gas best accommodates your wire, be it argon, carbon dioxide or a mix of the two. The kind of job you’re working on dictates specific kinds of wires and gas. Additionally, the contact tip recess you use varies depending on the type of project you hope to complete. Generally, you want to increase the size of the recess in conjunction with the current.

Point Your Wire at the Leading Edge of the Weld Puddle

To ensure best accuracy during the MIG welding process, keep your electrode pointed at the leading edge (i.e., toward the metal that has not yet been welded) of the weld puddle or pool. If you’re welding in an unusual position, you should use a wire with a smaller diameter to keep the weld pool small and minimize drip.

Tungsten Inert Gas (TIG) Welding

TIG welding, otherwise known as gas tungsten arc welding (GTA or GTAW), is a process that uses a tungsten electrode aided by a shielding gas, usually argon or helium, to fuse metal. This process is more precise than MIG welding, but also more time-consuming.

Choose the Right Rod Size for the Job

Ideally, the thickness of the rod should match the thickness of the metal you’re working on. You wouldn’t want to use a thick rod — say, 1/8” in diameter — on a weak piece of metal because you could easily put a hole through it with the sheer heat of the rod relative to the sheet. One benefit of TIG welding is the increased precision, but you still have to use the right tools to reap that advantage.

Clean Your Metal Before TIG Welding

If the metal you wish to TIG weld is rusted, scaled or painted, you’ll want to grind it down before you get started. Unlike MIG welding, TIG welding is more easily compromised if the metal is not clean. Polishing the metal alone will not suffice and can result in a tacky-looking finished product if you elect to take shortcuts in preparation.

Make Sure to Extend Your Tungsten Electrode to the Right Length

Having the tip of your electrode positioned at the proper length is crucial to the final product when you’re TIG welding. If the tip is not sticking out far enough, you won’t be able to see it — or, consequently, where you’re welding the metal. On the other hand, if the tip is out too far from the cup, the heat of the torch won’t be concentrated enough around the area you’re trying to weld and will probably end up melting your rod into the weld.

Safety Tips for Welding of All Kinds

It could be argued that many of the tips already presented fall into the category of safety tips, which is true. Having a working knowledge of the right equipment certainly contributes to minimizing the number of personal injuries experienced by welders. However, there are additional measures that should be taken to further reduce such risks.

Have a Spotter

It’s always a good idea to have someone watch you while you’re welding, if you can. This is especially true when welding around flammable materials. Having another set of eyes in the vicinity can reduce the risk of fires in the event that sparks get out of hand. Also, make sure to familiarize yourself with your surroundings and locate the nearest fire exits.

Personal Protective Equipment

Referred to as PPE for short, personal protective equipment is your first and last line of defense against heat, sparks and other hazards associated with welding. Wearing a mask with a shade dark enough to sufficiently protect your eyes from the brightness of the arc is an absolute must. You should also wear flame-retardant cotton or leather clothing with long sleeves and long pants, as well as fire-resistant gloves, to protect your extremities from sparks. Additional eye protection beneath the mask is also recommended, on top of some sort of ear protection to prevent impalement by debris.

Check Your Ventilation

It’s of the utmost importance that you are able to breathe clean air while you weld. You should always wear an approved respirator to protect your lungs against the fumes of dangerous metal oxide compounds. If you experience issues with your ventilation system, stop welding and address the problem immediately.
