Welding is an essential industrial process, but it can be dangerous if you’re inexperienced. Before you pick up your welding machine for your next project, be sure you’re prepared. The following guide will help you stay safe and knowledgeable about this process.

What to Know About Welding

1. Understand the Different Welding Processes

There are several ways to weld objects together. Wire welding method, like stick or metal inert gas (MIG), makes use of wires to join materials together. In stick welding, the wire electrode is melted to create filler that adds strength to the fusion. Its wire coating turns into gas that acts as a shield, protecting the weld against contaminants like nitrogen, oxygen, hydrogen, and water vapor that can weaken the joint. MIG welding, on the other hand, uses a welding gun, where the nozzle tip contains the consumable electrode wire while releasing the shielding gas for protection.

Tungsten inert gas (TIG) welding is a two-handed technique where a tungsten-tipped torch creates the spark for fusing and feeds inert gas to the weld. The filler metal is then added by dipping and removing it alternately into the weld pool instead of being continuously fed.

2. Learn the Right Input Voltage

Welding machines come in two voltages—110v and 230v. The higher the machine’s amp output, the more suitable it is for thicker materials. Find the equipment that offers both options through a built-in voltage amplifier circuit, allowing you to switch easily between the two over time.

3. Invest in Quality Welding Machine

Welding machines are devices that generate the electrical current used for welding. Some models are multi-purpose, which means you can use them for different techniques. Invest in a beginner-friendly welding machine with an easy-to-understand interface and automatic features that adjust settings according to the materials and consumables of your project.

4. Choose the Right Consumables

Consumables refer to the solid wire, covered electrode, or filler rod that gets consumed during the welding process. Depending on the welding technique used, they can offer protection by turning their coating into an inert gas, serve as filler metal for TIG welding, or form the heat source. Install the consumables securely to prevent leakages that can cause injuries and damage property.

5. Keep Safety in Mind

When welding, safety is paramount. Invest in the right gear, including glasses, fire-resistant clothing, gloves, and a welding helmet. Know the necessary safety protocols, such as adequate ventilation and proper distance from flammable materials, to prevent accidents.
