Method for joining tubular elements made of stainless steel, an alloy thereof, aluminum or other equivalent metallic materials |
摘要 |
A method for joining tubular elements made of stainless steel, an alloy thereof, aluminum or other equivalent metallic materials, particularly for providing coolant gas piping for refrigeration systems, comprising the steps of:
- deforming a first head portion (11a) of a first tubular element (11) so as to reduce its outside diameter to a size which allows its insertion in a second head portion (12a) of a second tubular element (12) to be joined to the first tubular element (11),
- inserting the first head portion (11a) in the second head portion (12a), so that a welding channel (15) is formed between the end (13) of the second head portion (12a) and the facing connecting portion (14) between the tubular body (11b) and the first head portion (11a) of the first tubular element (11a),
- performing a welding operation with the addition of material between the first element (11) and the second element (12) inside the welding channel (15). |
