Abrégé

A hybrid welding system that comprises a plasma welding unit (Plasma unit) and a MIG welding unit with a non-consumable electrode (cathode) and a consumable electrode, where the electrodes are positioned relative each other so that their respective axes form an angle α so that arcs initiated from the electrodes intersect a workpiece plane to define an impingement point distance D. A gas shielding nozzle forms a confined space around the tips of the electrodes, accommodates and covers them and keeps the angle α between them inside the confined space and impingement point distance D. The Plasma unit comprises thermal cooling means with a channel surrounding the cathode down to the nozzle and tip of the cathode and also the tip of the MIG electrode around the gas shielding nozzle. A heat absorbing fluid circulates inside the cooling channel, especially at the electrodes tips that concentrate the highest amount of heat at highest temperature. Electrically insulating porous ceramic cover and filler surround the cathode. Oval shaped magnetic horns control the distance D and prevent the electrical arcs of the two electrodes from deflecting from and brought closer to each other. This prevents disturbances in the melting pool and controls the deposition rate.

A hybrid welding system (100) that comprises a plasma welding unit (Plasma unit) (300) and a MIG welding unit (200) with a non¬ consumable electrode (cathode) (305) and a consumable electrode (225), where the electrodes are positioned relative each other so that their respective axes form an angle a so that arcs initiated from the electrodes intersect a workpiece plane to define an impingement point distance D. A gas shielding nozzle (345) forms a confined space around the tips of the electrodes, accommodates and covers them and keeps the angle a between them inside the confined space and impingement point distance D. The Plasma unit (300) comprises thermal cooling means with a channel (320) surrounding the cathode (305) down to the nozzle (345) and tip of the cathode and also the tip of the MIG electrode around the gas shielding nozzle (345). A heat absorbing fluid circulates inside the cooling channel (320), especially at the electrodes tips that concentrate the highest amount of heat at highest temperature. Electrically insulating porous ceramic cover (500) and filler (510) surround the cathode (305). Oval shaped magnetic horns (610) control the distance D and prevent the electrical arcs of the two electrodes from deflecting from and brought closer to each other. This prevents disturbances in the melting pool and controls the deposition rate.

The invention is an apparatus and method for Orbital welding of pipes or pipe segments together to form a pipeline, i.e., Orbital welding. A scanner welding unit, a control unit and a welding unit are combined to travel along and above a seam, which is formed between two interfacing base/cylindrical surfaces of every two pipe or pipe segments, scan the pipes/pipe segments relative positioning, alignment and levelling, and their surface geometry and topography and overlay a welding material starting from the root layer at the bottom of the seam and up to its edge and sealing it with a capping layer. The welding unit lowers a welding tip into the seam that may rotate on its axis at different angels relative to the surface during welding. The scanner unit may alert on mismatches on the relative position of the pipes/pipe segments before or after welding and in some cases enable repositioning for a more hermetically sealed weld.
