摘要
At least one welding torch is moved along a guide to define a fixed path along a joint to be welded. The torch position is sensed to provide location signals which control the recovery from a store of welding parameter signals, corresp. to respective locations, which control the welding operation to provide the desired welding parameter. Used partic. welding joints in a workpiece or interconnected workpieces such as oil or gas transmission pipes. System provides automatic welding of pipe joints etc. with an improved rate of metal deposition and improved quality of weld.
