Afrox claims that ‘one of the most innovative recent developments to take place in the South African welding and cutting industry’ is the launch of its Lindoflamm® special torches and burners from parent company, The Linde Group.
A first for South Africa, the Lindoflamm® special torches and burners provide optimal heat transfer to the work piece, reducing gas consumption, improving productivity, quality and therefore total cost — as well as enhancing safety on the factory floor.
Afrox’s Johan Pieterse, Business Manager, Process Development, explains, “Our parent company’s research and development activities focus not only on improving existing customer processes, but also on completely new technologies. Lindoflamm is a perfect example of this, offering pre-heating, flame straightening and heat treatment solutions for manufacturers and fabricators working to the highest industry standards.”
Pre-heating with acetylene and compressed air, Pieterse explains, is a critical requirement in the fabrication industry and plays a very important role in the integrity of the weld. It prevents failures such as hydrogen-induced cracking, as well as common failures in the heat-affected zone. An increasing number of fine-grained structural steels are being used for the construction of structures, apparatus, and equipment – increasing the importance of pre-heating prior to welding.
