Short intro to welding

With various types of welding and consumables, the topic might seem a bit overwhelming. However, this short guide to welding basics will help you understand the correct type of welding necessary for your application and which consumables you need from a reputable company like MiCan Industrial Supplies.

Types of welding

MIG (gas metal arc welding) is a method of arc welding that uses a small wire supplied via a tube to weld to metal. It is quicker, cheaper, and simpler than TIG welding and is often employed for automotive and do-it-yourself tasks. TIG (gas tungsten arc welding) necessitates the use of both hands as well as a foot (to operate the foot pedal). As a result, it is more expensive, time-consuming, and challenging to use when welding big pieces of stainless steel or non-ferrous material. Plasma cutters require expert control since they employ a high-energy beam to fuse the material.

Guide to welding consumables

Welding, like any other skill, does not become second nature quickly. Becoming a qualified welder can take anything from seven months to two years and much more to properly understand the dozens of diverse techniques, materials, and instruments that professional welders use every day. To create great, lasting welds on every project, you must grasp the science behind the processes, including knowing the link between process and materials and selecting the appropriate consumables like welding rods, welding wires, and welding electrodes.

Flux-cored vs solid wire

MIG welding employs a continuous supply of solid wire and a shielding gas supplied from a separate bottle to protect the weld pool from impurities. The shielding gas is usually argon or a 75 – 35 percent mixture of argon and carbon dioxide, or argon and helium. It is suitable for working with thinner materials like sheet metal and will create a nice, clean weld under these conditions. Flux-cored wires can be further categorised into two types: gas-shielded and self-shielded. Like solid wire, gas shielded flux cored wire necessitates using a bottle of gas to protect the weld pool. On the other hand, self-shielding wire produces its own shielding gas when the flux core is burnt. As a result, flux-cored wire is more portable since it does not require an extra gas tank. Gas shielded and self-shielding flux-cored wires are both appropriate for usage on heavier materials and in outdoor applications. Seamed and seamless flux-cored wire is another sub-category. Flux-cored wire is typically manufactured by putting powdered flux core material into a U-shaped piece of outer material, which is then twisted and sealed lengthwise. This leaves a tiny seam down the length of the wire, which must be lubricated for it to pass smoothly through the welding machine. A certain amount of lubricant is unavoidably extruded into the weld pool, increasing the possibility of contaminants and resulting in a worse quality weld. The core material in a seamless flux-cored wire is poured into a hollow tube, resulting in a smooth wire that does not require lubrication.

Rod electrodes

Tungsten arc welding use rod electrodes. Through this process, the tungsten rod warms to melt the metal of the base material to generate the weld, and the rod itself is not consumed.

Welding safety

Welding is a challenging skill to grasp, and carelessness can easily cause injuries. These are a few critical points about welding safety to keep in mind.

Noise

Noise levels beyond a certain threshold might be harmful to your hearing. Heavy traffic, trains, lawnmowers, and motorcycles are all examples of this. Flame cutting may generate over 100dB of noise, putting you at risk of tinnitus, dizziness, and high blood pressure. Wearing earplugs can help you avoid irreversible hearing loss caused by prolonged exposure to loud high levels.

Electric shock

When working with live electrical circuits and molten metal, the chance of receiving a direct or secondary electrical shock is significant. Therefore, always take the required precautions.

Ultraviolet (UV) radiation

Arc-eye is a frequent and painful ailment caused by the intense light released during welding. When you don’t use a specialised welder’s visor or helmet, gases, sparks, dust, or other particles might cause vision loss.

Gases

Welding fumes include several substances that have been linked to respiratory problems. Wearing a respirator mask will assist in filtering the air. While a welding profession might be demanding, taking care of one’s health and safety on the work can make it a tremendously rewarding one.
