The use of lasers in manufacturing is becoming more wide spread and is suitable for a wide range of processes such as cutting, welding, drilling and engraving / marking.
To meet the needs and challenges of our laser customers, BOC's LASERLINE® encompasses the complete package of gases, customised gas supply systems and a range of added value technical services.
The use of lasers for cutting has been utilised since the 1960s. Whilst the use of C02 lasers remains critical, the growth in the use of solid state or fibre lasers has been a significant technological development in recent years.
The requirements of our customers are also evolving and include issues surrounding gas purity and the cutting of more unusual materials, with the correct selection of 'Laser' and 'Assist' gas being critical.
Laser gases - are used to generate the laser light. The correct gas quality is essential to maintain high laser reliability and ensure process productivity.
Assist gases - the choice of assist gas is extremely important and can have a significant effect on the process quality and productivity.
The use of lasers for welding is gathering momentum, particularly in applications that previously employed resistance welding.
Utilised in a range of industrial environments, from micro-electronics manufacturing to shipbuilding, it's the automotive sector that has taken the lead in the development of laser welding offering the following benefits over resistance welding:
Lower heat input
Small heat affected zone (HAZ)
Lower distortion rate
Higher welding speed
The correct selection of welding gas plays a critical role. Aside from protecting the molten and heat affected areas of the workpiece against the ambient atmosphere, it helps to increase welding speeds whilst improving the mechanical properties of the weld.
