Basics of distortion in welding

Basics of distortion in welding

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...

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...
An overview of the mechanical properties of metals

An overview of the mechanical properties of metals

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...
Why do we use Colour in Welding?

Why do we use Colour in Welding?

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...
The Basics of Electricity in Welding

The Basics of Electricity in Welding

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...
