Abstract
The present invention relates to an active agent for low-carbon steel tungsten argon arc welding, which is prepared from 48 wt% of SiO2, 12 wt% of NaCl, 10 wt% of Cr2O3, 16 wt% of TiO2, 8 wt% of MnO and 6 wt% of B2O3. A certain amount of active agent is placed in a container. A right amount of acetone is added, and the active agent is made into paste. The pasty active agent is coated at the surface of a workpiece to be welded by a flat hair brush, and welding can be carried out after the acetone is volatilized. The active agent can obviously increase the penetration depth of the welding, the heat input of the workpiece is reduced, and the welding deformation is minimum. Meanwhile, the sensitivity of the penetration depth to the fluctuation of trace elements of base materials can be effectively reduced.
Description
Technical field
The present invention is a kind of activating agent that is applied in the argon tungsten-arc welding (TIG weldering).
Technical background
Argon tungsten-arc welding can be used for the connection of all metals, but that its weak point is a welding penetration is shallow, and production efficiency is not high.Single track welding mild steel, fusion penetration only about 3mm, for the butt joint of the slab more than the 3mm, need bevel, fill silk, and multi-pass welding just can be finished, and welding deformation is also bigger.To the thick steel plate of 10mm, to weld 5,6 roads usually and just can finish.Another problem that TIG welding low-carbon steel exists is, welding penetration is wayward, and fusion penetration fluctuates along with the fluctuation of the trace element in the mother metal (as O, S).Under identical welding conditions condition, often can not get identical welding penetration, bring a lot of inconvenience to practical operation.Ukraine's crust institute of welding has used the activating agent that is used for titanium alloy first in order to solve the problems referred to above that exist in the titanium alloy T IG welding.Be not used in the activating agent of low-carbon steel argon tungsten-arc welding at present.
Summary of the invention
The present invention is a kind of activating agent that is used for mild steel TIG weldering, is by SiO
2, NaCl, Cr
2O
3, TiO
2, MnO, B
2O
3Form, its weight proportion is: SiO
2: 48～52%, NaCl:8～12%, Cr
2O
3: 6～10%, TiO
2: 12～16%, MnO:8%, B
2O
3: 6%.According to above-described activating agent, be Powdered, add acetone to activating agent in use, make it become pasty state, the pasty state activating agent is applied, treat to weld after the acetone volatilization.
Specific implementation
The activating agent weight proportion of most preferred embodiment of the present invention is: SiO
2: 48%, NaCl:12%, Cr
2O
3: TiO 10%,
2: 16%, MnO:8%, B
2O
3: 6%.To the welding conditions that thickness of slab is 6,8, the low-carbon steel plate of 10mm is taked be:
The thickness of slab current/voltage welds fast arc length welding gun inclination angle throughput
mm A V cm/min mm ° L/min
6 140 12-13 70 3 90 8
8 160 12-14 70 3 90 10
10 260 14-18 70 3 90 12
A certain amount of activating agent is placed container, add proper amount of acetone, make it become pasty state.With flat hairbrush the pasty state activating agent is coated on surface of the work to be welded, coating thickness is advisable can hide the mother metal true qualities, and the about 20mm of coating width, every meter welding bead activating agent consumption treat just can weld after the acetone volatilization about 0.3g.
When not using activating agent, the thick sheet material of welding 10mm need be opened double V-groove, fills silk, and five, six roads just can be finished.Welding Angular Deformation reaches 10.When using activating agent, can make fusion penetration increase by 2.5 times.For the butt joint of the mild steel below the 10mm, need not bevel, adopt the straight flange groove not stay the gap butt joint, can once weld and finish.
Use activating agent of the present invention, welding penetration is significantly increased, but the electric current of welding remains unchanged, so under identical welding current condition, reduced the heat input of workpiece, the distortion of welding is minimum.Can effectively reduce simultaneously the sensitiveness of weld penetration to the fluctuation of mother metal trace element.
