Titanium alloy is in Laser-MIG Composite Welding process; because titanium alloy chemistry activity is very high; add that the fast high-temperature area area of Laser-MIG Composite Welding speed is larger, welding high-temperature area is very easily subject to the pollution of surrounding environment, therefore must carry out strict gas shield to welding high-temperature area.Adopt of existing Titanium Laser Welding dragged cover, frock or realizes the protection to welding high-temperature region to methods such as weld seam injecting protective gas more; but it is fast that these methods are difficult to adapt to titanium alloy Laser-MIG Composite Welding speed; the features such as welding high-temperature area is large, protection effect is poor.
Summary of the invention
For the deficiencies in the prior art; the present invention proposes a kind of gas shield device of titanium alloy Laser-MIG Composite Welding; for titanium alloy Laser-MIG Composite Welding feature, design and adapt to the fast gas shield device with welding the problems such as high-temperature area is large of laser-MIG hybrid welding speed of welding.
The present invention adopts following technical scheme to realize:
A gas shield device for titanium alloy Laser-MIG Composite Welding, mainly comprises: MIG torch head, jointing, drag cover main body; Also comprise: protection letter shoot joint, connecting plate, porous escape pipe, high-temperature flexible shirt rim;
Wherein, MIG torch head is connected with dragging cover main body by jointing, drags cover main body and MIG torch head relative position and angle to regulate by jointing, and high-temperature flexible shirt rim is arranged on drags cover bottom part body; Drag cover body front end to be connected with connecting plate; Porous escape pipe is placed in to drag in cover main body and by protection letter shoot joint and connects protection source of the gas.
Particularly,
Drag cover main body and MIG torch head relative position and angle, regulate by the governor motion on jointing; This governor motion is holding screw.
Dragging cover main body and weld seam tangential direction angular range is 5 °～30 °; Dragging the height adjustment range of the relative MIG torch head of cover main body is 0～10mm.
High-temperature flexible shirt rim adopts stainless steel or its refractory metal material to manufacture, and structure is that multilayered metal film connects by knot that can be undone by a pull.
High-temperature flexible shirt rim can self adaptation cover main body and the gap of surface of the work, the automatic adjustment height 0～10mm in high-temperature flexible shirt rim; Drag cover main body to contact by high-temperature flexible shirt rim with surface of the work, protection zone and external environment condition are kept apart.
MIG torch head, drag cover main body and connecting plate to connect into continuous protection zone, laser-MIG welding pool and weld seam are formed to continuous protection.
Advantage of the present invention is: drag cover main body to be connected with MIG torch head by jointing, connection angle, position and fastening degree can regulate by the screw on jointing.This device can be in Laser-MIG Composite Welding process; dragging cover body interior porous escape pipe to be connected with the protective gas carrier pipe that drags cover afterbody; can be discharged into equably around weld seam; constantly provide sufficient protection gas to weld seam, guarantee the welding quality of weld seam, simultaneously; drag cover and workpiece to pass through high-temperature flexible shirt rim close contact; realize with surface of the work and fitting well, can effectively isolate and improve protection effect protection zone, and not produce movement interference with workpiece.The present invention can adapt to preferably laser-MIG hybrid welding speed of welding soon and weld the features such as high-temperature area is large, protects respond well.
