There has recently been a lot of misconceptions around different respirators, particularly P2 and N95 masks. We have outlined and explained the differences between respirator standards and their applications. What is P1 Rating? P1 is a respiratory filter rating under the AS/NZS1716 standards for use in Australia and New Zealand. Protects against mechanically generated particles. […]

Having Porosity Problems with Gasless MIG Welding Wire?
Porosity (air bubbles or pin holes in the weld metal) is not only ugly, but it will also significantly weaken the weld joint. Here’s a checklist to help you diagnose what is causing the problem: 1) Check the Polarity The wrong polarity will cause porosity and a host of other problems too. Check that […]

What makes metals different?
The properties of metals explained Metals and alloys have various mechanical, thermal and electrical properties that set them apart from each other and make them more suited to a particular task. The following properties will need to be considered when welding or selecting a metal for a particular task. Hardness Hardness is a desirable property […]
The History of Welding
Welding is not a recent development, but is continually evolving to suit different design and manufacturing requirements. Many joins required to withstand heavy loads were joined using hot riveting, where a red-hot rivet was placed through two overlapping sections of metal and hammered over. As the rivet cooled it contracted, forming a tight join between […]
The History of Aluminium
Aluminum (also known as aluminium) is the most abundant metal element in the earth’s crust. And it’s a good thing, too, because we use a lot of it. About 41 million tons are smelted each year and employed in a wide arrange of applications. From auto bodies to beer cans, and from electrical cables to aircraft […]
The history of Iron & Steel
The development of steel can be traced back 4000 years to the beginning of the Iron Age. Proving to be harder and stronger than bronze, which had previously been the most widely used metal, iron began to displace bronze in weaponry and tools. For the following few thousand years, however, the quality of iron produced would depend as […]

How does a Punch and Die actually work?
Punching with Punch & Die tooling is a more versatile method than Jobber Drilling for repetitive hole cutting. Punch & Dies allow greater flexibility with regards to size, dimensions and efficiency. Drilling alternatives can be limited by the size and the dimensions of the hole needing to be drilled. Larger diameter holes require pre-drilling and […]
