Gas-pressure welding

the welding process with heating of metal by gas flame and by sagging (pressing) the heated details. Heating is produced by multi-ardent welding torches with the large quantity (to hundred and more) of small fires, evenly distributed over the nagrevayemoy surface, which partially is fused in 1-2 min,

Gas-pressure welding it is joint pipes; 1 - burner; 2- pipe; 3- fires of burner; 4 channels for the gas; 5- channels for the cooling water; 6- joint of pipes.

they squeeze and are connected after which detail. Heating is conducted usually by acetylene-oxygen flame, sediment it is produced by hydraulic device with the clamps for the durable seizure of the combinable details. G. s. produce, for example., jointing conduits (Fig.), RR rails and the like G. s. is frequently substituted by electric resistance welding, k. K. khrenov.
