How Carbon Content Affects the Weldability of Steels

And its effects on strength, hardness, ductility and machinability

Steel is an alloy of iron and carbon along with several other elements in small quantities, all of which have an impact on its properties. Steels can contain varying amounts of carbon and are typically categorized as low, medium or high carbon steels. Low carbon steels are those containing 0.30% carbon or less.  Medium carbon […]

The Importance of the Heat Affected Zone (HAZ)

When we weld we generate enough heat in the welding arc to melt the filler metal and base material.  Or just the base material is we are welding autogenously (as in GTAW without filler).  The edges of the base material melt and combine with the filler metal to create what is called the composite zone.  […]

How to Weld High Carbon Steels

High carbon steels are those containing 0.45% carbon or higher. They are typically considered “hard to weld” because they are crack sensitive and are susceptible to undergoing significant changes in their physical and mechanical properties after welding.  However, high carbon steels can be welded successfully and without problems by having a sound understanding of the […]

How to Weld Abrasion Resistant – AR – Plate

Abrasion resistant (AR) steel plate is used in applications requiring abrasion and impact resistance.  It is alloyed with high levels of carbon in order to attain high levels of hardness through the quenched and tempered process.  AR plate is primarily used in conveyors, buckets, dump liners, construction attachments, grates, body armor and ballistic plates. AR […]
