Hyundai Heavy Industries Co. Ltd. (HHI), the world’s biggest shipbuilder and a leading offshore facilities contractor, announced that it has developed a new automatic welding process to build offshore facilities.
The new hot-wire TIG (Tungsten Inert Gas) robot welding process combines conventional hot-wire TIG welding with the 6-axis robot that HHI independently developed. The robot works six times faster than manual welding, as it can continuously supply more welding wires. Also, it features a remote control system to enhance work efficiency.
HHI will apply this automatic welding to special pipes, made of duplex and super duplex stainless steel, to build offshore facilities such as FPSOs and offshore platforms under construction at its offshore yard, beginning this month.
