When you’re aiming for clean and successful welds, the way you initiate the arc plays an important role. In TIG welding (Gas tungsten arc welding –GTAW), getting off to the right start isn’t just about skill; it’s about choosing the right technique for the job. Today, we will compare tig welding ignition methods: scratch vs lift…
When it comes to welding, one of the most critical aspects to understand is the different types of joints in welding that are utilized to create strong and durable welded structures. The joint is where two pieces of metal are fused together through the welding process. Selecting and properly preparing the right type of joint…
AC and DC welding are two different types of welding currents that affect how the arc is created and maintained between the electrode and the workpiece. AC stands for alternating current, which changes its direction periodically. DC stands for direct current, which flows in one direction only. The choice of welding current can have a…
Flux-Core and MIG welding are two of the most commonly used welding techniques. Flux-Core welding uses a continuously-fed consumable electrode, which is shielded by a flux compound to protect the weld area from atmospheric contamination. MIG welding, on the other hand, uses a continuously-fed consumable wire electrode and a shielding gas to protect the weld…
What is the Right Shielding Gas for Welding Aluminum? Controlling aluminium welds entails a variety of elements, including selecting the proper filler metal and shielding gas composition, as well as ensuring your power supply is properly set up to ensure quality welds as the end result. Inert Shielding Gases When deciding what is the right…
What is the best shielding gas for welding stainless steel? Welding stainless steel may be accomplished in a variety of methods, each requiring a particular shielding gas. We will examine the most popular stainless steel welding methods and determine which gas types is best for each. Properties of Stainless Steel Stainless steel has been used…
What is the best shielding gas for welding mild steel? There are many different ways that you can choose to weld mild steel and with each arc process a different shielding gas is likely to be need. In this article we look at the most common processes used in welding mild steel and assess which…
MIG welding gases. The choice of shielding gas is crucial in Gas Metal Arc Welding (GMAW), more commonly known as MIG welding. Discover how to choose the best shielding gas for your task. Shielded gas-assisted MIG welding delivers cleaner and quicker welds, eliminating the need to constantly change electrodes just like you would with stick…
Fusing Metal – welding is the process in which two pieces of metal are fused together using heat and or pressure. Welding is therefore a fabrication process that is a crucial part of the manufacturing operations and, as with any manufacturing processes, the welding procedure used to fabricate a part or structure is dependent on…
Reverse polarity welding and when to use it is a question that crops up regularly. It is an important topic as it will drastically affect the quality of the weld. To understand when you should employ reverse polarity welding you need to have a grasp of current and polarity as a whole. In this article…
