Orbital-TlG-a great way to join pipes

摘要

Although pipes have been welded using mechanised systems since the 1960's, the TIG-process still accounts for a considerable amount of manual welding. Yet, there are many good reasons to explore the use of orbital TIG-welding for applications ranging from single-run welding of thin-walled stainless pipes to multi-run welding of thick-walled pipes, and even narrow-gap welding: centre dot Young welders are difficult to recruit. centre dot Operator ergonomics are improved significantly. centre dot Remote control and video control options. centre dot Increased duty cycle - so higher productivity. centre dot Welding procedures repeatable - resulting in a consistent weld quality. centre dot Good control over heat input. centre dot Equipment available for use "on site". There are two main catagories of mechanised welding systems: centre dot Stationary: the welding head has a fixed position while the pipe rotates. centre dot Orbital: the pipe has a fixed horizontal or vertical position while the welding head rotates.
