Aluminium Welding: How to Weld Aluminium Aluminum is a lightweight, thin metal which is used commonly in  welding workshops . With this metal, welding has to be done at low temperatures. Otherwise, you will simply wind up blowing holes in your materials. Aluminum is quite reactive, so forms an oxide layer when it’s exposed. This poses a challenge to welding as it leads to permeable welds, so you’ll need to scrub the oxide layer from utilizing a wire brush before welding. Nevertheless, you’ll have to work quickly as it will take simply a matter of moments to form once again.   Knowing the best ways to weld aluminum is tougher than welding steel, as it requires a great deal more care, factor to consider, and customized devices. Each different kind of welding needs different equipment and strategies, once you comprehend everything that’s involved, aluminum welds look clean, smooth, wise, and they’re resistant. Why use aluminum? Aluminum is among the most popular materials ...

The sheet metal production process powers Australian industry– almost every kind of producer relies, in some way, on parts, specialized components, structures, or devices that is a direct outcome of sheet metal fabrication. From big commercial structures and supports to the most sensitive digital assemblies, sheet metal plays a key role. Exactly what is the sheet metal working procedure? Sheet metal fabrication is made up of almost as many individual processes and tools as the applications it serves. Their common goal, from laser cutting, to push brake forming, is to convert a sheet of metallic product into use for a particular task. This can be achieved with some methods. Bending and Forming The bending procedure in sheet metal utilizes unique tools, such as press brakes, to produce U flexes, V flexes, and custom forms from flat metal sheets. Folding, machining, and stamping are all typical methods to flex or form metal. Rotary and elastomer flexing can produce brand-new shapes e...

How Computer Design Effects Melbourne Sheet Metal Fabrication in 2018 How Computerized Design Impacted Sheet Metal In 1957, Patrick J. Hanratty, a computer scientist and “father of computer-aided design (CAD) and manufacturing (CAM)”, developed PRONTO, which was the first commercial numerical-control programming system. In 1960, Ivan Sutherland, a computer scientist and “father of computer graphics”, created SKETCHPAD, which demonstrated the basic principles and feasibility of computer technical drawing, at the  Massachusetts Institute of Technology  Lincoln Laboratory in Cambridge, Massachusetts. PRONTO, SKETCHPAD, And Synthavision The first CAD systems, like PRONTO and SKETCHPAD, served as technical replacements of drawing boards. While continuing to use two-dimensional ideas, designers created technical drawings that consisted from 2D wireframe primitives like a line, arc, B-spline, and so on. Productivity of design increased, but the original computer softwares cost...

Welding Gifts That’ll Make Christmas Awesome Welders are not easy people to shop for, but you wouldn’t expect that people who fuse metal together for a living would be.Despite this, we  love the welders in our lives  and only want the best for them. To help you on your mission to buy that  perfect gift for your  welder  in Melbourne , we recently asked many of our welder friends and co-workers what they’d love to receive from their loved ones during the holidays. This list is a result of that research, and hopefully it’ll help you on your way to gifting bliss. 1. Welding Gear Bag With Helmet Catch By Revco Welding is a gear-intensive disciple, what with all the protective gear and welding tools that are an essential part of the process. This welding gear bag by Revco is specially designed with compartments for all the welding accessories needed to get the job done, and best of all – a helmet catch that can fit most types of welding helmets. The bag is very ...

Disposable Masks vs PAPR respirators for welding and cutting processes When asking ‘what is the best respirator for welding and metal cutting?’ a number of factors need to be considered. But first we’ll give a bit of background. The fumes given off during welding or a hot cutting process is a varying mixture of airborne gases and very fine particles. Respirators protect from welding fumes which are formed when the metal is heated above its boiling point and vapours condense in the atmosphere creating very fine, solid particulates. These particulates can be a mixture of metallic oxides, silicates and fluorides. If inhaled, they may cause ill health and are often dismissed or not correctly protected against. Welding fumes are recognised internationally and are classified as a possibly carcinogenic to humans should we be exposed to them for long or even regular short periods of time. It is also generally accepted that stainless steel fumes are more hazardous than that of mild (carbon...

From Twist Drills to Rotabroach Cutters – The Evolution of Hole Making For over 100 years the most common method of producing holes in steel work was with conventional type twist drills. The 1970’s saw the first ever annular hole cutter which became known worldwide as the Rotabroach cutter. With the introduction of TCT cutters 15 years later, mag drills have evolved from the two man operation “widow makers” weighing 45kg to now just weighing 8.5kg. The Widow Maker Stephen A.  Morse  of East Bridgewater, Massachusetts invented the twist drill in 1861. They have remained the most common way of producing holes, up to this present day. The early drill bits were manufactured by producing two grooves opposite sides to each other in a round bar, the bar was then twisted to produce the flutes. Nowadays, the flutes of the drill bit are ground into the bar by rotating and passing the bar over a grind wheel which precision grinds the flutes. The force and energy required to the produ...
