Description
Technical field
The present invention relates to technical fields, and in particular to a method of for box beam bottom welding.
Background technique
Existing box beam backing weld method generally includes argon arc welding, welding electrode arc welding, automatic consumable electrode gas-arc
Weldering plus ceramic substrate.There are following disadvantages for these methods: the backing welding carried out using argon arc welding, welding electrode arc welding, butt welding
The operation level requirement of work is higher, and it is easy to appear burning and being lack of penetration in actual production, weldquality is difficult to control.
The backing welding carried out using argon arc welding, welding electrode arc welding, low efficiency, back of weld poor flatness need to polish or machine, at
This height.The backing welding for adding ceramic substrate to carry out using automatic gas metal-arc welding, ceramic substrate needs are pasted onto liner support
On plate, and it also requires liner supporting plate is fixed in tooling, mechanism is cumbersome, laborious time-consuming.
Summary of the invention
The present invention is intended to provide a kind of method for box beam bottom welding.
The invention provides the following technical scheme:
A method of it, will be pre- as needed between insulating joint box beam and insulating joint for box beam bottom welding
Standby group is padded in back of weld sticking flexible in the axially proximate interface solid point postwelding of insulating joint box beam, is then adopted to gap
Bottoming tack welding is carried out with automatic gas metal-arc welding to fix；The box beam clamping to be welded that solid point is welded is to rotating welding
In tooling；Angle of welding gun is adjusted to 30 °~50 °, and adjusts welding gun to the position of weld seam, electrode extension 10-15mm；It adjusts
Automatic welding bottoming is carried out with bottom welding technological parameter, operator is by observation monitor in welding process, according to monitor
The molten bath state and intermittent condition of upper real-time online carry out welding parameter fine tuning, until bottoming process terminates, after bottoming again
Capping parameter is called to be filled capping to box beam.
The argon arc welding solid point is that solid point weld seam is formed at 120 ° of solid points 1 along welded workpiece circumferencial direction.
In the backing welding parameter, angle of welding gun: 30 °~50 °；Carry on the back protection air-flow amount: 20L/min, welding in the pipeline back side
Degree: 365 °；It fills in capping parameter, welding degree: 1095 °.
Compared with prior art, the beneficial effects of the present invention are: the present invention is since back of weld has liner, molten iron will not flow
The defects of dropping down, realize one side welding with back formation, overlap, pit will not be generated, due to smooth welded seam, eliminate postwelding polishing,
Turning process, has saved welding wire, saves machining period, accelerates manufacturing schedule, reduces technical difficulty of operation；Improve weldering
Stitch quality, the purpose that structure is simple and convenient to operate, is at low cost, being easy to promote and apply in production, easy to operate, labor intensity
Low, weld is accepted rate is high, and back of weld is smooth, and postwelding does not need to be processed back of weld.
Specific embodiment
Below in conjunction with the embodiment of the present invention, technical scheme in the embodiment of the invention is clearly and completely described,
