Based on the analysis of the stress-strain state of welded joints, it is shown that when welding saddle branches to existing gas pipelines at low temperatures using the proposed technology and standard welding, the differences in the values of stresses and displacements occurring are insignificant. Numerical calculations have shown that when welding a saddle branch at low temperatures using the proposed technology, it can be expected that the joint strength will not be lower than when welding under standard conditions.
