Introduction Do you need a cutting tool for occasional repair and maintenance work? Did you recently embark on a new upscale project that requires higher cutting volumes? Are you looking for an alternative to your current mechanical saw? These scenarios provide great reasons to investigate plasma cutting. With the cost of machines on the decline, smaller-sized, portable machines flooding the market and technology offering increased benefits and easier usage — it may be time to take a serious look at plasma for your cutting applications. The benefits of plasma cutting include ease of […]

Welding cast iron steels

September 12, 2011Welding Cast Iron, Welding Guides

WELDING OF CAST IRON Cast iron is an extremely versatile material, used in thousands of industrial products. It is hard, wear-resistant, and relatively inexpensive. Like steel, it is available in many different grades and compositions. While we usually think of cast iron as being brittle (having low ductility), this is not true of all cast irons, as we shall see shortly. Cast iron, like steel, is an iron-carbon alloy. In composition and structure, and in some of its properties, it is quite different from steel. While many grades of cast […]

Guidelines for Welding Cast Iron Tips and Techniques SOURCE: Lincoln Electric Guidelines for Welding Cast Iron Background Cast iron is difficult, but not impossible, to weld. In most cases, welding on cast iron involves repairs to castings, not joining casting to other members. The repairs may be made in the foundry where the castings are produced, or may be made to repair casting defects that are discovered after the part is machined. Mis-machined cast iron parts may require repair welding, such as when holes are drilled in the wrong location. […]

Pulse welding – Mig pulsed welder

August 28, 2011Mig Welding Articles

Pulsed MIG May Solve Aluminum Fabrication Problems — Q&A Q: What’s the difference between spray transfer and pulsed spray transfer? A: Pulsed spray transfer, commonly called pulsed MIG, puts less heat into the work yet maintains many benefits of spray transfer, such as good fusion, high deposition rates and/or fast travel speeds. In pulsed spray transfer, the power source switches between a high peak current and a low background current. The peak current pinches off a spray transfer droplet and propels it toward the weldment. The background current maintains […]

Buying a MIG welder

May 13, 2011Mig Welding Articles

Courtesy of DIY Welding UK, visit this article at their site. The main difference between cheap and expensive MIG welders is ease of use. For anyone new to welding that can equate to possibility of use. ——————————————————————————– It’s really difficult to put the differences into words. On the forum we have a section that helps people learn to MIG weld where people can post photos of their welds and ask for advice. It’s easy to tell from the photos which price range people have bought in. Those who have bought […]

Welding Acronyms – Meaning of welding terms.

May 10, 20112 commentsWelding Acronyms, Welding Guides

Arc [Arc Length] – The physical gap between the end of the electrode and the point where the arc makes contact with the base metal. Duty-cycle – As per EN/AS50974.1, the minutes out of a 10-minute period a welder / welding machine can be operated at maximum rated output. For example, a 60% duty cycle @ 300 Amps means that the welding machine can be used for 6 minutes (at 300 Amps) and then must be allowed to cool with the fan running for 4 minutes. This reduces the chance of […]

What is Plasma Cutting?

April 20, 2011Plasma Cutting

WHAT IS PLASMA CUTTING? Plasma cutting is a process that is used to cut steel and other metals of different thicknesses (or sometimes other materials) using a plasma torch. In this process compressed air is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. The plasma is sufficiently hot to melt the metal being cut and moves sufficiently fast to blow molten metal away […]

Tig Welding

April 19, 201120 commentsTig Welding

Tig Welding, Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors […]
