Abstract
The invention discloses a protection gas for welding a steel wheel, which comprises the following ingredients by volume percent: 87 to 94 percent of argon, 5 to 10 percent of carbon dioxide and 1 to 3 percent of oxygen. Appropriate oxygen is added in the original gas, so the drop transfer of weld metal can be increased while the electric arc is stabilized, the drop transfer current can be reduced, the metal wetting quality can be improved, a better weld seam shape can be obtained, and at the same time the welding splash can be greatly reduced.
Description
Technical field
The invention belongs to passenger car with steel wheel assembly welding procedure, be specifically related to the steel wheel welding and use protective gas.
Background technology
Wheel welding is the important process that wheel is produced, and the quality of welding procedure directly influences the presentation quality and the security performance of product.
At present, wheel industry welding protection gas adopts the form of argon gas and carbon dioxide mix gas mostly.Argon gas is an inert gas, mainly plays the effect of shrinking electric arc.Carbon dioxide is to improve speed of welding as the major advantage of protective gas, and the molten bath is darker.But the existence of carbon dioxide also has its disadvantageous place, is exactly that particle transition meeting causes appearance of weld not add, and produces more splashing.
Summary of the invention
The object of the present invention is to provide a kind of steel wheel welding to use protective gas; In original protection gas, add suitable oxygen, in stable arc, can increase the droplet transfer of weld metal; Reduce the droplet transfer electric current; Improve the metal wellability, obtain appearance of weld better, greatly reduce the generation of spatter simultaneously.
For achieving the above object, technical scheme of the present invention is:
Protective gas is used in the steel wheel welding, and its composition percent by volume is: argon gas 87～94%, carbon dioxide 5～10%, oxygen 1～3%.
Under welding parameters such as identical electric current, voltage, speed of welding and gas flow; Adjustment different protective gases proportioning, welding are accomplished the back and are found a kind of The Best Mixed to protect the gas proportioning according to quality of weld seam molding, spatter particle what, spatter particle diameter size and weld penetration situation.
Beneficial effect of the present invention
Compare with traditional protection gas (argon gas+carbon dioxide), protective gas of the present invention adds minor amounts of oxygen simultaneously through improving argon content, reducing the carbon dioxide gas body burden; Make welding arc more stable; Increase the droplet transfer of weld metal, reduced the droplet transfer electric current, improved the metal wellability; Obtain appearance of weld better, simultaneously because the minimizing of carbon dioxide greatly reduces the generation of spatter.
The specific embodiment
Below in conjunction with embodiment the present invention is further specified.
Table 1 is the embodiment of the invention.
Table 1 unit: volume ratio
| Argon gas | Carbon dioxide | Oxygen | |
| Embodiment 1 | 87％ | 10％ | 3％ |
| Embodiment 2 | 92％ | 5％ | 3％ |
| Embodiment 3 | 94％ | 5％ | 1％ |
| Embodiment 4 | 93％ | 5％ | 2％ |
| Embodiment 5 | 91％ | 7％ | 2％ |
| Embodiment 6 | 89％ | 8％ | 3％ |
| Comparative example | 85％ | 15％ | - |
Guaranteeing under the identical situation of other welding parameter, adopting traditional binary gas welding to connect to connect and do contrast with ternary gas welding of the present invention.
The present invention's three vigour and comparative example two vigour are respectively got two wheels and are done contrast; The particle diameter mean value that splashes after tradition adopts the binary gas welding to connect is respectively 1.23mm, 1.22mm, and the particle diameter mean value that splashes after adopting ternary gas welding of the present invention to connect is respectively 0.87mm, 0.77mm.And it is obviously many than three vigour to splash after traditional binary gas welding connects.Simultaneously, the state that guarantees spray transfer weld down the fusion penetration that thin plate adopts three vigour to obtain being fit to (0.5～1.0mm), but adopt traditional binary gas welding connect fusion penetration often excessive (>=1.3mm), sometimes even burn-through sheet material.
Adopt ternary of the present invention protection gas welding to connect, can realize the conversion of short circuiting transfer to spray transfer, the particle that splashes obviously reduce and particle diameter little; Electric arc is comparatively stable, and weld penetration is shaped better; Quality of weld seam molding is good, weld seam machinery function admirable.
