Hardfacing Techniques and the Requirements During Its Processing! The equipments which are used for drilling stones or mountains, digging the ground and farming are made of strong iron but with time they get failed to perform the given task due to losing the grip that creates friction. In Austria, most of the metal equipments are made following hardfacing technologies. This can be done by build-up, overlay or by combining both. Build-up technique is used to refurbish old equipments and to give back the same original shape by placing weld layers on the top end. Overlay is done protect the equipment from losing its metal during use in extreme situations. If we combine both of them, it helps in extending an equipments life and durability for best results.
The welding process depends on the shape and size of the equipment. Hardfacing on a small scale can be done using stick or flux-cored welding processes while to hardface thick and large size equipments, submerged arc welding process is suitable. Read More:-
