Welding wire is a metal filament supplied in coils, spools, reels or individual rods (rods). It is used as an additive for welding operations in manual (MMA, TIG), automatic (SAW) or semi-automatic (MIG, MAG) mode in shielding gases, as well as for cutting (CUT) steels, non-ferrous metals. When melted during welding, it fills the weld…
In the 19th century, types of metal structures were joined by riveting. For example, this is how the famous Eiffel Tower was made. In the XX century, metal was most often joined by welding. And in the XXI century, the most relevant way of connecting metals is gluing, a convenient alternative to welding. Metal-to-metal bonding is a process in…
TIG (Tungsten Inert Gas) welding, also known as GTAW (Gas Tungsten Arc Welding), is an arc aluminum for beginners process that uses a non-consumable tungsten electrode to produce the weld using a tig torch and welding machine. The weld area is protected from contamination by an inert shielding gas, usually argon or helium. TIG welding…
As a professional welder, I often get asked – what is MIG welding? In simple terms, MIG (metal inert gas) welding, also known as GMAW (gas metal arc welding), is a versatile, economical fusion welding process that joins metal pieces together by heating them with an electric arc established between a continuously fed wire electrode…
Table of Contents Introduction Knowing how to properly repair plastic items is an invaluable skill that can save money while reducing environmental waste. As more and more plastic products enter our homes and workplaces, cracks and breaks are inevitable. Rather than throwing these items away and further adding to the plastic pollution crisis, simple repair…
Brazing aluminum is a useful technique for joining aluminum parts. It creates strong, sealed joints by melting and flowing a filler metal into the joint clearance. Here is a step-by-step guide to brazing aluminum. Materials Needed The main materials needed for aluminum brazing include: Type Examples Torch Propane torch, oxy-acetylene torch Brazing rods 4043, 4145,…
Aluminum has become ubiquitous across many industries due to its viele desirable properties. Its lightweight yet strong nature makes it ideal for applications ranging from automobile manufacturing to building construction. While aluminum fabricating often utilizes TIG welding using a tig welder, MIG welding aluminum using a mig machine has been growing in popularity as the…
For example: If your device uses 60 Watts and is plugged into a 120V outlet, then: Amps = Watts / Volts Amps = 60W / 120V Amps = 0.5 Amps So if the device uses 60 Watts from a 120 volt power source, the current or amperage needed is 0.5 Amps. To summarize, divide the…
Do you also believe that white-collar workers have a high income than blue-collar workers? Just because they dress professionally and go to an air-conditioned office daily does not make them earn more. Sometimes, the case is the opposite. The blue-collar workers can generate high incomes too. One common profession that can lead to this is…
What is a tungsten electrode and where is it used? A tungsten electrode is a round rod made of pure tungsten or tungsten with additives (alloying agents). Tungsten is used in argon-arc TIG welding with a non-melting electrode. If you are wondering why “non-melting”, the answer is very simple. Tungsten has the highest melting point…
