In TIG welding (Tungsten inert gas), the welding arc is formed between a non-consumable tungsten electrode and the workpiece. The shielding gas is always an inert gas that does not affect the welding process per se. Usually, the shielding gas is argon and it protects not only the molten weld but also the electrode in the torch from oxygenation. The filler material may not be necessary for TIG welding. The pieces can be fused also by melting the groove together. If a filler is used, it is fed into the molten weld manually and not through the welding torch as in MIG/MAG welding. Therefore, the TIG welding torch has a completely different structure than  a MIG/MAG torch . Various  TIG welding  methods include, for example, the DC TIG welding method that uses direct current, AC TIG welding that utilizes alternating current and pulse TIG.     What is Lift-Arc TIG Ignition? With the Lift-Arc Ignition feature, to start the arc the tungsten electrode is touched on the ...

Welding is a serious job. It is used to join pieces of metal together and is a very skilled trade. So what are the different types of welding and what are they used for in industry?   Stick Welding Stick welding, also known as Arc welding , is doing it the old-fashioned way. Stick welding is a bit harder to master than MIG welding, but you can pick up stick welding equipment for very little if you want to have a go at home. Stick welding uses a stick electrode welding rod.   MIG Welding MIG welding  is one of the easier types of welding for beginners to learn. MIG welding is actually two different types of welding. The first use bare wire and the second flux core. Bare wire MIG welding can be used to join thin pieces of metal together. Flux core MIG welding can be used outdoors because it does not require a flow meter or gas supply. MIG welding is usually the welding of choice for DIY enthusiasts and hobby welders who don’t have the money to spend on expensive equip...

Plasma cutting is a process that we have seen evolve from its humble beginnings in the 1960s to its current popularity as a widespread cutting technology for a wide range of industries, from manufacturing shops to automotive repair and restoration to industrial construction to salvage and scrap operations. In this blog, we will take an in-depth look at what plasma cutting is and how it works, as well as the advantages and disadvantages of the technology.   What is plasma cutting and how does it work? Plasma is a conductive, ionized gas-like substance. It has long been used as a very effective material for cutting steel, stainless steel, aluminum, brass, copper and many other conductive metals in the correct environment. Following the application of computer numerical control (CNC) technology in the 1980s and recent manufacturing improvements,  plasma cutting machines  not only offer advantages over conventional cutting due to the absence of metal chips, producing cleaner...
