How does distortion occur? Welding usually involves heating of the materials at the joint to fuse them together. This heat creates expansion and contraction. If the heating and cooling is uneven, distortion can occur. This distortion comes from residual stress. There...
At Technoweld, we are often approached about the best practice for welding, in particular, GTAW (TIG welding) of a pipe. We’ve compiled some best practices around pipe joints. This blog is important for those completing the welding tickets as it is specifically...
In part 3 of the Gas Metal Arc Welding (GMAW) blog, we will discuss the power circuit. Often people forget the basics when setting up gas metal arc welding machines, it’s these basics that create a lot of frustration with welders. Welding is complex but it doesn’t...
Mechanical property is a material’s capacity to cope with a range of applied external forces such as shear stresses, load, weather conditions, and time. Mechanical engineers can measure the ability of the metal to resist shearing, stretching, twisting, compressing or...
There is a myriad of reasons you might, or might not, like your welds or metal to display a variety of colours. You may be a sculptor creating a new piece of welded steel artwork, the colours are unlike anything else. Welding in itself is an art. The various colours...
Arc Welding is the process by which two pieces of metal are joined together by the use of electrical energy. Arc welding creates an electric arc that melts the base metal and typically a filler wire. The subsequent pool of molten metal then solidifies and fuses the...
The basic requirement of welding management is having a qualified welding procedure and qualified welders to AS1554 or AS3992. When starting a project, it is important to understand what the project requires, or you may get caught out. As a minimum, the purchase order...
Golden Rules of Welding explains the basics of welding. Developed by Technoweld Director, Graham Fry who holds a Bachelor of Adult Education, international welding engineer, a vast number of nationally and internationally recognised supervision/inspection...
Are you looking to demonstrate your personal competence to existing clients and prospective employers? Perhaps you want to prove the competence of your welding staff to customers and clients? Gaining a CSWIP certification in the relevant welding related disciplines is...
Whether you have a small welding business or are a multinational manufacturing company, your ultimate goal should always be to create a high-quality product with a long lifespan. No matter how experienced your welders are, to consistently provide welding quality of...
