Welding technology has come a long way. There was a time when the only available way to join two pieces of metal were rudimentary joints. MIG welding is a process by which a solid wire electrode is used to join two metal plates. You feed the wire electrode through a welding gun and onto the welding pool. In the welding process, you also send an arc which protects the weld pool from any forms of contamination during the welding process through the welding gun. Whether you are new to welding or have some intermediate level of skill, here are three guidelines that can simplify the process for you.
The Safety of the Operator
Safety is what determines the quality and efficiency of a welding job. Before you start soldering the two pieces of metal together, you are advised to check for possible hazards. The most common risks to welding are electric shock, arc rays, fumes, gases, hot parts and noise. Wearing the right gear, which includes bodysuits, welding glasses, gloves and the right boots, will protect you from most of these hazards. Additionally, ensure the room you are welding in is properly ventilated as this reduces the risk of suffocation. If you are doubtful about the flow of air, invest in a respirator.
The Soundness of the Connections
Before you switch on the power source and start welding, check your connections and ensure they are tight and secure. Start with the front of the gun and walk backward to the electric cord connecting it to the power outlet. Always ensure that the ground cable is close to your worktable whenever you are handling the welding task. Finally, use compressed air when removing all debris that collects on the consumable parts of the gun.
The Suitable Shielding Gas
Different wires will react differently to different types of shielding gases. Some wires will do well when shielded with carbon dioxide, others will do well with argon or a mixture of the two. If you are not sure about the best shielding gas for your wire type, consult an expert to help you match them correctly. Carbon steel wire, for example, is properly protected by carbon or carbon and argon shielding gas.
These are a few of the safety guidelines to follow when setting up the work station for a welding job. If you aren't sure you can handle welding on your own, it is best to choose a competent welder to handle it for you.Share
