Technical field
The present invention relates to the inside and outside welders of a kind of steel pipe and flange welding.
Background technology
When large-scale pipeline welds, relatively effective welding procedure is two-sided welding, that is, relies on inside and outside welder to steel pipe
Inside and outside two sides is carried out with the interconnecting piece of flange to weld simultaneously.This just needs a kind of device that can execute inside and outside two sides welding, i.e.,
Inside and outside welder.
It is disclosed in Chinese invention patent ZL201210166735.2 " a kind of inside and outside two-sided welding device of steel pipe and flange "
The inside and outside welder of a kind of steel pipe and flange welding, wherein " internal welding device includes internal welding machine head, is arranged on board
The first guide rail, the welding machine seat being slidably disposed on the first guide rail and the pushing meanss for elapsing welding machine seat, it is described in
Welding head is set on welding machine seat, and first guide rail is located at the same side of connection template with driven wheel, and the first guide rail is along even
The axis direction for connecing template is extended；The internal welding machine head can be stretched into along the first guide rail in intercommunicating pore "；Its outer welder packet
It includes lifting and traversing equipment, outer welding head is set to the matched slide bar outer end of a lateral guide groove.As it can be seen that the technology of the patent of invention
In scheme, internal welding device can only be in axial translation, and outer welder can only also be moved in longitudinal and axial both direction, adjusts
It is smaller to save dimension, is especially unable to Butt welding gun and carries out angle adjustment with respect to the spatiality of steel pipe and the attachment weld of flange.
And a kind of Chinese invention patent application " welder of pipe and the two-sided automatic welding of flange "（Application publication number CN
104607766 A）In disclosed technology, " internal welding device with outer welder include and stand on pedestal pillar, make
Crossbeam be fixed on pillar casing I and fastening bolt, so that welding gun is fixed on crossbeam welding gun casing, installation and casing on weldering
Rifle wig-wag, the welding gun casing connect with the casing II on crossbeam ".It is well known that welding oscillator is a kind of general weldering
Ancillary equipment is connect, it can be achieved that welding gun swings along bead direction, for increasing weld width.But its welding wire angle can only opened
Adjustment casing cannot adjust at any time in the welding process with respect to the angle of crossbeam when beginning to pass through installation before welding, it more difficult to realize certainly
Dynamic adjustment.
